NEW QUESTION # 33
Refer to Exhibit:
A company has deployed 200 AP-635 access points. To take advantage of the 6 GHz band, the administrator has attempted to configure a new WPA3-OWE SSID in Central but is not working as expected.
What would be the correct action to fix the issue?
- A. Change the SSID to WPA3-Enhanced Open.
- B. Change the SSID to WPA3-Enterprise (CNSA).
- C. Change the SSID to WPA3-Personal.
- D. Change the SSID to WPA3-Enterprise (CCM).
Answer: A
Explanation:
The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.
WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:
Select the Security Level from the drop-down list. The following options are available:
WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.
WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.
WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.
WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.
The other options are incorrect because:
A) WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
B) WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.
D) WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
NEW QUESTION # 34
A company deployed Dynamic Segmentation with their CX switches and Gateways After performing a security audit on their network, they discovered that the tunnels built between the CX switch and the Aruba Gateway are not encrypted. The company is concerned that bad actors could try to insert spoofed messages on the Gateway to disrupt communications or obtain information about the network.
Which action must the administrator perform to address this situation?
- A. Enable Enhanced PAPI security
- B. Enable Enhanced security
- C. Enable GRE security
- D. Enable Secure Mode Enhanced
Answer: B
Explanation:
Explanation
To address the situation of unencrypted tunnels between the CX switch and the Aruba Gateway, the administrator must enable Enhanced security on both devices. Enhanced security is a feature that provides encryption and authentication for GRE tunnels between CX switches and Aruba Gateways using IPSec.
Enhanced security can be enabled globally or per tunnel on both devices using CLI commands or Web UI options. The other options are incorrect because they either do not provide encryption or authentication for GRE tunnels or do not exist as features. References:

NEW QUESTION # 35
In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?
- A. No encryption is applied.
- B. RADIUS protocol is utilized.
- C. Authentication information is not exchanged
- D. The Gateway will not respond.
Answer: C
Explanation:
Explanation
This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE. References:

NEW QUESTION # 36
You need to ensure that voice traffic sent through an ArubaOS-CX switch arrives with minimal latency What is the best scheduling technology to use for this task?
- A. QoS shaping
- B. Strict queuing
- C. DWRR queuing
- D. Rate limiting
Answer: B
Explanation:
Explanation
Strict queuing is the best scheduling technology to use for voice traffic on an AOS-CX switch. Scheduling is a mechanism that determines how packets are transmitted from different queues on an egress port. Strict queuing is a scheduling method that gives the highest priority queue absolute preference over all other queues, regardless of their size or utilization. Voice traffic should be assigned to the highest priority queue and scheduled with strict queuing to ensure minimal latency and jitter. The other options are incorrect because they are either not scheduling methods or not optimal for voice traffic. References:

NEW QUESTION # 38
You are doing tests in your lab and with the following equipment specifications
* AP1 has a radio that generates a 10 dBm signal
* AP2 has a radio that generates a 11 dBm signal
* AP1 has an antenna with a gain of 9 dBi
* AP2 has an antenna with a gain of 12 dBi.
* The antenna cable for AP1 has a 2 dB loss
* The antenna cable for AP2 has a 3 dB loss
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for APT?
- A. 26 dBm
- B. 30 dBm
- C. 17 dBm
- D. -12 dBm
Answer: C
Explanation:
The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.
EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:
EIRP = P + G - L
where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.
For AP1, we have:
P = 10 dBm G = 9 dBi L = 2 dB
Therefore,
EIRP = 10 + 9 - 2 EIRP = 17 dBm

NEW QUESTION # 40
You are setting up a customer's 15 headless loT devices that do not support 802.1X. What should you use?
- A. Multiple Pre-Shared Keys (MPSK) with WPA3-AES
- B. Clearpass with WPA3-PSK
- C. Multiple Pre-Shared Keys (MPSK) Local
- D. Clearpass with WPA3-AES
Answer: C
Explanation:
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

NEW QUESTION # 41
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A. routed port in custom VRF
- B. SVI, VLAN trunk allowed all on ISL in default VRF
- C. loopback 0 and OSPF area 0 in default VRF
- D. SVI, VLAN trunk allowed all on ISL in custom VRF
Answer: A
Explanation:
Explanation
To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF. References:

NEW QUESTION # 42
You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The show arp command displays the ARP table for a specific VRF or all VRFs on the switch. The ARP table contains the IP address to MAC address mappings for hosts that are directly connected to the switch or reachable through a gateway. If the client device is connected to another switch by VSX LAG, the ARP entry for the client device will not be present on the primary switch unless it has communicated with it recently. Therefore, to find the IP address of the client device, the administrator should run the show arp command on the secondary switch in the VSX pair, specifying the VRF name that contains the client device's subnet.

What are the requirements to ensure that WMM is working effectively'? (Select two)
- A. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
- B. The Aruba AOS10 APs installed have to be converted to controlled mode
- C. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
- D. The AP needs to be connected via a tagged VLAN to the wired port
- E. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
Answer: A,C
Explanation:
Explanation
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work. References:

- C. The optimal rate for sending multicast frames is based on the lowest broadcast rate across all associated clients.
- D. The optimal rate for sending multicast frames is based on the lowest unicast rate across all associated clients.
Answer: D
Explanation:
Explanation
multicast transmission optimization is a feature that allows the IAP to select the optimal rate for sending broadcast and multicast frames based on the lowest of unicast rates across all associated clients1. When this option is enabled, multicast traffic can be sent at up to 24 Mbps. The default rate for sending frames for 2.4 GHz is 1 Mbps and 5.0 GHz is 6 Mbps. This option is disabled by default1.
NEW QUESTION # 45
Refer to the exhibit.
A company has deployed 200 AP-635 access points. To but is not working as expected What would be the correct action to fix the issue?
- A. Change the SSID to WPA3-Personal
- B. Change the SSID to WPA3-Enhanced Open
- C. Change the SSID to WPA3-Enterprise (CCM).
- D. Change the SSID to WPA3-Enterpnse (CNSA).
Answer: D
Explanation:
Explanation
According to the Aruba Campus Access Professional documents1, WPA3-Enterprise is a security mode that supports 802.1X authentication and encryption with either AES-CCM or AES-GCMP. WPA3-Enterprise also optionally adds usage of Suite-B 192-bit minimum-level security suite that is aligned with Commercial National Security Algorithm (CNSA) for enterprise networks2. This mode provides the highest level of security and is suitable for government and financial institutions.
The exhibit shows that the SSID is configured with WPA3-Enterprise (CCM), which uses AES-CCM as the encryption protocol. However, this mode is not compatible with some devices that require CNSA compliance.
Therefore, changing the SSID to WPA3-Enterprise (CNSA) would fix the issue and allow all devices to connect to the network.

A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch'? (Select two )
- A. On the source AOS-CX switch, the destination specified is the administrators desktop
- B. The encapsulation protocol used is VXLAN.
- C. The encapsulation protocol used is GRE.
- D. The encapsulation protocol is UDP.
- E. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
Answer: A,C
Explanation:
Explanation
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''
- A. Role-based policies enhance User Based Tunneling across the campus network and the policy traffic is protected with iPsec
- B. Group Based Policy ID is applied on egress VTEP after device authentication and policy is enforced on ingress VTEP
- C. Role-based policies are tied to IP addresses which have an advantage over IP-based policies and role names are sent between VTEPs
- D. Group Based Policy ID is applied on ingress VTEP after device authentication and policy is enforced on egress VTEP
Answer: D
Explanation:
Explanation
This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms. References:

NEW QUESTION # 49
When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?
- A. MAC tables
- B. UDLD
- C. QSVI
- D. RPVST+
Answer: A
Explanation:
Explanation
The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B. MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.
One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.

With the Aruba CX 6000 24G switch with uplinks of 1/1/25 and what does the switch do when a client port detects a loop and the do-not-disabie parameter is used?
- A. The network analytics engine is triggered.
- B. Port status led blinks in amber with 100hz.
- C. An event log message is created.
- D. Port status will be validated once status is cleared
Answer: C
Explanation:
Explanation
The correct answer is B. An event log message is created.
The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.
The other options are incorrect because:
A: Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable1.
C: The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.
D: Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.
