z Regarding the NSSA area of ​​the OSPF protocol, the following statements are incorrect: _______

• A. Only one ABR can exist in an NSSA area
• B. There can be multiple ASBRs in an NSSA area
• C. Tpe7 LSA must be injected into the NSSA area
• D. ABRs in NSSA areas must convert Tpe7 LSAs to Tpe5 LSAs

In the topology shown in the figure, the following configurations are performed on RTA and RTB respectively:
RTA-ospf-1-area-0.0.0.1]network 192.168.0.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.1.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.2.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.3.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.4.0 0.0.0.255 Now it is required that the RTC cannot learn the routes configured in the above RTA, what configuration can be performed on the router?

• A. RTB-ospf-1-area-0.0.0.1]abr-summar192.168.0.0 255.255.248.0 not-advertise
• B. RTB-ospf-1-area-0.0.0.0]abr-summar192.168.0.0 255.255.0.0 not-advertise
• C. RTC-ospf-1-area-0.0.0.1]abr-summar192.168.0.0 255.255.224.0 not-advertise
• D. RTB-ospf-1-area-0.0.0.1]abr-summar192.168.0.0 255.255.252.0 not-advertise

Which of the following statements about IS-IS and OSPF is true _______.

• A. An IS-IS router can only belong to one area, and different interfaces of an OSPF router can belong to multiple areas
• B. IS-IS is better than OSPF in scalability, but OSPF is more widely used
• C. The backbone area of ​​IS-IS must be Area0 and must be continuous
• D. IS-IS operates at the transport layer, OSPF operates at the network layer, both use the SPF algorithm

The three autonomous systems AS200 shown in the figure are the filtering ASs of AS100 and AS300, among which AS100 advertises the route 10.1.1.0/24 to AS200.
The main device configuration is as follows:
RTC:
bgp 100
network 10.1.1.0 255.255.255.0
undo snchronization
peer 200.1.2.2 as-number 200
peer 200.1.2.2 route-policCOM export
peer 200.1.2.2 advertise-communit# ,
route-policCOM permit node 10
applcommunit100:100
#
RTB
#
bgp 200
undo snchronization
peer 200.1.2.1 as-number 100
peer 200.1.3.2 as-number 300
peer 200.1.2.1 route-policCOM import
peer 200.1.3.2 advertise-communit#
route-policCOM permit node 10
if-match communit10
applcommunit200:200
#
ip communit-list 10 permit 100:100
Then on the RTC, the correct statement about the routing of 10.1.1.0/24 is ____.

• A. Its community attribute is <100:100> , <200:200> , because the community attribute is actually appended by the intermediate AS.
• B. Its community attribute is empty because the community attribute will not be passed to the external AS any more.
• C. Its community attribute is <100:100> because the community attribute represents the source of the route.
• D. Its community attribute is <200:200> because the community attribute was changed by the intermediate AS.

The network is shown in the figure, requiring RTA and RTB to establish OSPF neighbor relationship and exchange routes. To achieve the above purpose, please complete the configuration of RTA. RTA]ipv6
