NEW QUESTION # 54
Your GRE tunnel is not transitioning to the Upstatus. What would be the first step in troubleshooting the problem?

  • A. Verify tunnel endpoint reachability.
  • B. Verify that the status of the management interface is up.
  • C. Verify the status of the management routing instance.
  • D. Verify that the routing instance for GRE tunnels is created.

Answer: A


NEW QUESTION # 55
You have DHCP snooping enabled but no entries are automatically created in the snooping database for an interface on your EX Series switch. What are two reasons for the problem? (Choose two.)

  • A. Dynamic ARP inspection is enabled on the interface.
  • B. MAC limiting is enabled on the interface.
  • C. The device that is connected to the interface has a static IP address.
  • D. The device that is connected to the interface has performed a DHCPRELEASE.

Answer: B,C

Explanation:
The DHCP snooping feature in Juniper Networks' EX Series switches works by building a binding database that maps the IP address, MAC address, lease time, binding type, VLAN number, and interface information 1
. This database is used to filter and validate DHCP messages from untrusted sources 1 .
However, there are certain conditions that could prevent entries from being automatically created in the snooping database for an interface:
* MAC limiting: If MAC limiting is enabled on the interface, it could potentially interfere with the operation of DHCP snooping. MAC limiting restricts the number of MAC addresses that can be learned on a physical interface to prevent MAC flooding attacks 1 . This could inadvertently limit the number of DHCP clients that can be learned on an interface, thus preventing new entries from being added to the DHCP snooping database.
* Static IP address : If the device connected to the interface is configured with a static IP address, it will not go through the DHCP process and therefore will not have an entry in the DHCP snooping database
1 . The DHCP snooping feature relies on monitoring DHCP messages to build its database 1 , so devices with static IP addresses that do not send DHCP messages will not have their information added.
Therefore, options B and C are correct. Options A and D are not correct because performing a DHCPRELEASE would simply remove an existing entry from the database 1 , and Dynamic ARP inspection (DAI) uses the information stored in the DHCP snooping binding database but does not prevent entries from being created 1 .


NEW QUESTION # 56
What is the default MAC age-out timer on an EX Series switch?

  • A. 300 seconds
  • B. 30 seconds
  • C. 30 minutes
  • D. 300 minutes

Answer: A

Explanation:
The default MAC age-out timer on an EX Series switch is 300 seconds 1 2 . The MAC age-out timer is the maximum time that an entry can remain in the MAC table before it "ages out," or is removed 3 1 . This configuration can influence efficiency of network resource use by affecting the amount of traffic that is flooded to all interfaces 1 . When traffic is received for MAC addresses no longer in the Ethernet routing table, the router floods the traffic to all interfaces 1 .


NEW QUESTION # 57
Exhibit.

The ispi _ inet. 0 route table has currently no routes in it.
What will happen when you commit the configuration shown on the exhibit?

  • A. The inet. 0 route table will be completely overwritten by the ispi . inet. 0 route table.
  • B. The ISPI . inet. 0 route table will be imported into the inet. 0 route table.
  • C. The inet. 0 route table will be imported into the ispi . inet. 0 route table.
  • D. The ISPI . inet. 0 route table will be completely overwritten by the inet. o route table.

Answer: C

Explanation:
Explanation
The configuration shown in the exhibit is an example of a routing instance of type virtual-router. A routing instance is a collection of routing tables, interfaces, and routing protocol parameters that create a separate routing domain on a Juniper device1. A virtual-router routing instance allows administrators to divide a device into multiple independent virtual routers, each with its own routing table2.
The configuration also includes a rib-group statement, which is used to import routes from one routing table to another. A rib-group consists of an import-rib statement, which specifies the source routing table, and an export-rib statement, which specifies the destination routing table.
In this case, the rib-group name is inet-to-ispi, and the import-rib statement specifies inet.0 as the source routing table. The export-rib statement specifies ispi.inet.0 as the destination routing table. This means that the routes from inet.0 will be imported into ispi.inet.0.
Therefore, the correct answer is B. The inet.0 route table will be imported into the ispi.inet.0 route table.

NEW QUESTION # 58
Exhibit

You have configured a GRE tunnel. To reduce the risk of dropping traffic, you have configured a keepalive OAM probe to monitor the state of the tunnel; however, traffic drops are still occurring.
Referring to the exhibit, what is the problem?

  • A. For GRE tunnels, the OAM protocol requires that the BFD protocols also be used.
  • B. The "event link-adjacency-loss" option must be set.
  • C. LLDP needs to be removed from the gr-1/1/10.1 interface.
  • D. The hold-time value must be two times the keepalive-time value

Answer: D

Explanation:
Explanation
A keepalive OAM probe is a mechanism that can be used to monitor the state of a GRE tunnel and detect any failures in the tunnel path. A keepalive OAM probe consists of sending periodic packets from one end of the tunnel to the other and expecting a reply. If no reply is received within a specified time, the tunnel is considered down and the line protocol of the tunnel interface is changed to down1.
To configure a keepalive OAM probe for a GRE tunnel, you need to specify two parameters: the keepalive-time and the hold-time. The keepalive-time is the interval between each keepalive packet sent by the local router. The hold-time is the maximum time that the local router waits for a reply from the remote router before declaring the tunnel down2.
According to the Juniper Networks documentation, the hold-time value must be two times the keepalive-time value for a GRE tunnel2. This is because the hold-time value must account for both the round-trip time of the keepalive packet and the processing time of the remote router. If the hold-time value is too small, it may cause false positives and unnecessary tunnel flaps.
In the exhibit, the configuration shows that the keepalive-time is set to 10 seconds and the hold-time is set to
15 seconds for the gr-1/1/10.1 interface. This means that the local router will send a keepalive packet every 10 seconds and will wait for 15 seconds for a reply from the remote router. However, this hold-time value is not two times the keepalive-time value, which violates the recommended configuration. This may cause traffic drops if the remote router takes longer than 15 seconds to reply.
Therefore, option D is correct, because the hold-time value must be two times the keepalive-time value for a GRE tunnel. Option A is incorrect, because BFD is not required for GRE tunnels; BFD is another protocol that can be used to monitor tunnels, but it is not compatible with GRE keepalives3. Option B is incorrect, because the "event link-adjacency-loss" option is not related to GRE tunnels; it is an option that can be used to trigger an action when a link goes down4. Option C is incorrect, because LLDP does not need to be removed from the gr-1/1/10.1 interface; LLDP is a protocol that can be used to discover neighboring devices and their capabilities, but it does not interfere with GRE tunnels5.

NEW QUESTION # 59
Exhibit

Your BGP neighbors, one in the USA and one in France, are not establishing a connection with each other.
Referring to the exhibit, which statement is correct?

  • A. The BFD liveness is set too high.
  • B. The BFD liveness must be configured on the BGP group.
  • C. The BFD liveness must be configured on the BGP neighbor.
  • D. The BFD liveness is set too low.

Answer: C

Explanation:
* The exhibit shows the configuration of BFD liveness detection for BGP at the global level, which applies to all BGP neighbors by default 1 . However, this configuration does not specify the session mode, which determines whether BFD uses single-hop or multihop mode to communicate with a neighbor 2 .
* For single-hop BGP neighbors, which are directly connected on the same subnet, the session mode can be either automatic or single-hop. For multihop BGP neighbors, which are not directly connected and require multiple hops to reach, the session mode must be multihop 2 .
* Since your BGP neighbors are in different countries, they are likely to be multihop neighbors. Therefore, you need to configure the session mode as multihop for each neighbor individually at the [edit protocols bgp group group-name neighbor address bfd-liveness-detection] hierarchy level 2 . For example:
protocols { bgp { group usa { neighbor 192.0.2.1 { bfd-liveness-detection { session-mode multihop; } } } group france { neighbor 198.51.100.1 { bfd-liveness-detection { session-mode multihop; } } } } }
* If you do not configure the session mode for multihop neighbors, BFD will use the default mode of automatic, which will try to use single-hop mode and fail to establish a BFD session with the remote neighbor 2 . This will prevent BGP from using BFD to detect liveliness and failover.
* Therefore, the answer B is correct, as you need to configure the BFD liveness detection on the BGP neighbor level with the appropriate session mode for multihop neighbors.


NEW QUESTION # 60
Which statement about aggregate routes is correct?

  • A. Aggregate routes are used for advertising summarized network prefixes.
  • B. Aggregate routes are automatically generated for all of the subnets in a routing table.
  • C. Aggregate routes are always preferred over more specific routes, even when the specific routes have a better path.
  • D. Aggregate routes can only be used for static routing but not for dynamic routing protocols.

Answer: A

Explanation:
Aggregate routes are used for advertising summarized network prefixes 1 2 . They help minimize the number of routing tables in an IP network by consolidating selected multiple routes into a single route advertisement 1
. This approach is in contrast to non-aggregation routing, in which every routing table contains a unique entry for each route 1 .
Therefore, option D is correct. Options A, B, and C are not correct because:
* Aggregate routes can be used with both static routing and dynamic routing protocols 1 .
* Aggregate routes are not automatically generated for all of the subnets in a routing table. They need to be manually configured 1 .
* Aggregate routes are not always preferred over more specific routes. The route selection process in Junos OS considers several factors, including route preference and metric, before determining the active route 1 .


NEW QUESTION # 61
Exhibit

You are a network operator troubleshooting BGP connectivity.
Which two statements are correct about the output shown in the exhibit? (Choose two.)

  • A. The routers are exchanging IPv4 routes.
  • B. The R1 is configured for AS 65400.
  • C. The BGP session is not established.
  • D. Peer 10.32.1.2 is configured for AS 63645.

Answer: A,B

Explanation:
The output of the show bgp neighbor command shows the following information:
* The local AS number of R1 is 65400, as indicated by the line "Local: 10.32.1.1+179 AS 65400".
* The peer AS number of 10.32.1.2 is 63645, as indicated by the line "Peer: 10.32.1.2+179 AS 63645".
* The BGP session is established, as indicated by the line "State: Established".
* The routers are exchanging IPv4 routes, as indicated by the line "Type: External State: Established Flags: < Sync > " and the table showing the number of prefixes received and sent for inet.0 routing table. References: Enterprise Routing and Switching, Specialist (JNCIS-ENT) - Juniper Networks ,

NEW QUESTION # 62
Which statement is correct about controlling the routes installed by a RIB group?

  • A. An import policy is applied to the RIB group.
  • B. An export policy is applied to the RIB group.
  • C. Only routes in the last table are installed.
  • D. A firewall filter must be configured to install routes in the RIB groups.

Answer: A

Explanation:
A RIB group is a configuration that allows a routing protocol to install routes into multiple routing tables in Junos OS. A RIB group consists of an import-rib statement, which specifies the source routing table, and an export-rib statement, which specifies the destination routing table or group. A RIB group can also include an import-policy statement, which specifies one or more policies to control which routes are imported into the destination routing table or group 1 .
An import policy is a policy statement that defines the criteria for accepting or rejecting routes from the source routing table. An import policy can also modify the attributes of the imported routes, such as preference, metric, or community. An import policy can be applied to a RIB group by using the import-policy statement under the [edit routing-options rib-groups] hierarchy level 1 .
Therefore, option A is correct, because an import policy is applied to the RIB group to control which routes are installed in the destination routing table or group. Option B is incorrect, because all routes in the source routing table are imported into the destination routing table or group, unless filtered by an import policy.
Option C is incorrect, because a firewall filter is not used to install routes in the RIB groups; a firewall filter is used to filter packets based on various criteria. Option D is incorrect, because an export policy is not applied to the RIB group; an export policy is applied to a routing protocol to control which routes are advertised to other devices.

NEW QUESTION # 63
Which statement is correct about graceful Routing Engine switchover (GRES)?

  • A. The PFE restarts and the kernel and interface information is lost.
  • B. With no other high availability features enabled, routing is preserved and the new master RE does not restart rpd.
  • C. When combined with NSR, routing is preserved and the new master RE does not restart rpd.
  • D. GRES has a helper mode and a restarting mode.

Answer: C

Explanation:
The Graceful Routing Engine Switchover (GRES) feature in Junos OS enables a router with redundant Routing Engines to continue forwarding packets, even if one Routing Engine fails.
GRES preserves interface and kernel information, ensuring that traffic is not interrupted.
However, GRES does not preserve the control plane.
To preserve routing during a switchover, GRES must be combined with either Graceful Restart protocol extensions or Nonstop Active Routing (NSR). When GRES is combined with NSR, nearly
75 percent of line rate worth of traffic per Packet Forwarding Engine remains uninterrupted during GRES. Any updates to the primary Routing Engine are replicated to the backup Routing Engine as soon as they occur.
Therefore, when GRES is combined with NSR, routing is preserved and the new master RE does not restart rpd.


NEW QUESTION # 64
Which statement is correct about IP-IP tunnels?

  • A. The TTL in the inner packet is decremented during transit to the tunnel endpoint.
  • B. IP-IP tunnels only support encapsulating non-IP traffic.
  • C. There are 24 bytes of overhead with IP-IP encapsulation.
  • D. IP-IP tunnels only support encapsulating IP traffic.

Answer: D

Explanation:
Explanation
IP-IP tunnels are a type of tunnels that use IP as both the encapsulating and encapsulated protocol. IP-IP tunnels are simple and easy to configure, but they do not provide any security or authentication features. IP-IP tunnels only support encapsulating IP traffic, which means that the payload of the inner packet must be an IP packet. IP-IP tunnels cannot encapsulate non-IP traffic, such as Ethernet frames or MPLS labels1.
Option A is correct, because IP-IP tunnels only support encapsulating IP traffic. Option B is incorrect, because IP-IP tunnels only support encapsulating non-IP traffic. Option C is incorrect, because the TTL in the inner packet is not decremented during transit to the tunnel endpoint. The TTL in the outer packet is decremented by each router along the path, but the TTL in the inner packet is preserved until it reaches the tunnel endpoint2.
Option D is incorrect, because there are 20 bytes of overhead with IP-IP encapsulation. The overhead consists of the header of the outer packet, which has a fixed size of 20 bytes for IPv43.

NEW QUESTION # 65
In RSTP, which three port roles are associated with the discarding state? (Choose three.)

  • A. disabled
  • B. alternate
  • C. root
  • D. designated
  • E. backup

Answer: A,B,E

Explanation:
Explanation
In Rapid Spanning Tree Protocol (RSTP), there are several port roles that determine the behavior of the port in the spanning tree123. The roles include root, designated, alternate, backup, and disabled123.
The discarding state is associated with the backup, alternate, and disabled roles123. In a stable topology with consistent port roles throughout the network, RSTP ensures that every root port and designated port immediately transition to the forwarding state while all alternate and backup ports are always in the discarding state2. Disabled ports are also in the discarding state3.
Therefore, options B, C, and D are correct.


NEW QUESTION # 66
You are receiving the BGP route shown in the exhibit from four different upstream ISPs.
Referring to the exhibit, which ISP will be selected as the active path?

  • A. ISP 2
  • B. ISP 4
  • C. ISP 1
  • D. ISP 3

Answer: B

Explanation:
In BGP, the path selection process is based on a set of attributes. The process starts by preferring the path with the highest weight, then the highest local preference, then the locally originated routes, and so on. If all these attributes are the same, then it prefers the path with the shortest AS path.
Referring to the exhibit, all four ISPs have the same weight, local preference, and origin.
However, ISP 4 has the shortest AS path. Therefore, ISP 4 will be selected as the active path.
So, option C is correct.


NEW QUESTION # 67

You have configured a GRE interface, but no traffic will flow.
Referring to the exhibit, which statement is true?

  • A. The gr-1/2/0 interface is an invalid GRE interface.
  • B. The IP subnet mask cannot be a /32.
  • C. The source and destination addresses cannot have the same third octet.
  • D. The unit number cannot be 0.

Answer: B


NEW QUESTION # 74
Exhibit

Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)

  • A. On R3 enable Level 1 on the ge-0/0/4 interface
  • B. On R1, enable Level 1 on the ge-0/0/1 interface.
  • C. On R1, disable Level 2 on the ge-0/0/1 interface.
  • D. On R3 disable Level 2 on the ge-0/0/4 interface.

Answer: A,B

Explanation:
Explanation
A: On R1, enable Level 1 on the ge-0/0/1 interface. In IS-IS, both levels (Level 1 and Level 2) are enabled by default when you enable IS-IS on an interface1. Level 1 systems route within an area2. If the destination is outside an area, Level 1 systems route toward a Level 2 system2. Therefore, enabling Level 1 on the ge-0/0/1 interface on R1 would allow packets to reach from R1 to R3.
D: On R3 enable Level 1 on the ge-0/0/4 interface Similarly, enabling Level 1 on the ge-0/0/4 interface on R3 would allow packets to reach from R1 to R3.
These explanations are based on the IS-IS configuration documents and learning resources available at Juniper Networks1 and Cisco34.


NEW QUESTION # 75
Which three protocols support BFD? (Choose three.)

  • A. OSPF
  • B. BGP
  • C. LACP
  • D. RSTP
  • E. FTP

Answer: A,B,C

Explanation:
Explanation
BFD is a protocol that can be used to quickly detect failures in the forwarding path between two adjacent routers or switches. BFD can be integrated with various routing protocols and link aggregation protocols to provide faster convergence and fault recovery.
According to the Juniper Networks documentation, the following protocols support BFD on Junos OS devices1:
BGP: BFD can be used to monitor the connectivity between BGP peers and trigger a session reset if a failure is detected. BFD can be configured for both internal and external BGP sessions, as well as for IPv4 and IPv6 address families2.
OSPF: BFD can be used to monitor the connectivity between OSPF neighbors and trigger a state change if a failure is detected. BFD can be configured for both OSPFv2 and OSPFv3 protocols, as well as for point-to-point and broadcast network types3.
LACP: BFD can be used to monitor the connectivity between LACP members and trigger a link state change if a failure is detected. BFD can be configured for both active and passive LACP modes, as well as for static and dynamic LAGs4.
Other protocols that support BFD on Junos OS devices are:
IS-IS: BFD can be used to monitor the connectivity between IS-IS neighbors and trigger a state change if a failure is detected. BFD can be configured for both level 1 and level 2 IS-IS adjacencies, as well as for point-to-point and broadcast network types.
RIP: BFD can be used to monitor the connectivity between RIP neighbors and trigger a route update if a failure is detected. BFD can be configured for both RIP version 1 and version 2 protocols, as well as for IPv4 and IPv6 address families.
VRRP: BFD can be used to monitor the connectivity between VRRP routers and trigger a priority change if a failure is detected. BFD can be configured for both VRRP version 2 and version 3 protocols, as well as for IPv4 and IPv6 address families.
The protocols that do not support BFD on Junos OS devices are:
RSTP: RSTP is a spanning tree protocol that provides loop prevention and rapid convergence in layer 2 networks. RSTP does not use BFD to detect link failures, but relies on its own hello mechanism that sends BPDU packets every 2 seconds by default.
FTP: FTP is an application layer protocol that is used to transfer files between hosts over a TCP connection. FTP does not use BFD to detect connection failures, but relies on TCP's own retransmission and timeout mechanisms.

NEW QUESTION # 78
Exhibit.

The ispi _ inet. 0 route table has currently no routes in it.
What will happen when you commit the configuration shown on the exhibit?

  • A. The inet. 0 route table will be completely overwritten by the ispi . inet. 0 route table.
  • B. The ISPI . inet. 0 route table will be imported into the inet. 0 route table.
  • C. The inet. 0 route table will be imported into the ispi . inet. 0 route table.
  • D. The ISPI . inet. 0 route table will be completely overwritten by the inet. o route table.

Answer: C

Explanation:
The configuration shown in the exhibit is an example of a routing instance of type virtual-router. A routing instance is a collection of routing tables, interfaces, and routing protocol parameters that create a separate routing domain on a Juniper device 1 . A virtual-router routing instance allows administrators to divide a device into multiple independent virtual routers, each with its own routing table 2 .
The configuration also includes a rib-group statement, which is used to import routes from one routing table to another. A rib-group consists of an import-rib statement, which specifies the source routing table, and an export-rib statement, which specifies the destination routing table.
In this case, the rib-group name is inet-to-ispi, and the import-rib statement specifies inet.0 as the source routing table. The export-rib statement specifies ispi.inet.0 as the destination routing table. This means that the routes from inet.0 will be imported into ispi.inet.0.
Therefore, the correct answer is B. The inet.0 route table will be imported into the ispi.inet.0 route table.
