Question 26

There are two Community-fiter:
ip communityfiter 1 pemit 100:1 200:1
ip community-filter 2 pemit 100:1
ip commmunityfiter2 pemit 200:1
Which of the following description about the above communityfite is correct? (Multiple choice)

A.A BGP route matches community-filter 2 as long as the community attributes carried in the route contain 100:1 or 200:1, or both.

B.A BGP route matches community-filter 2 only when the community attributes carried in the route contain both 100:1 and 200:1.

C.A BGP route matches community-filter 1 as long as the community attributes carried in the route contain 100:1 or 200:1, or both.

D.A BGP route matches community-filter 1 only when the community attributes carried in the route contain both 100:1 and 200:1.

Question 27

As shown in the figure, in the IPv4 and IPv6 environment, the SEL field in the ISIS NET address always takes the value 00.

A.False

B.True

Question 28

Which of the following description is wrong about the MPLS BGP VPN?

A.BGP Soo is used to prevent routes routed from a VPN site from going back to the site through the MPLS backbone. Soo is an extended community attribute automatically generated by MP-BGP.

B.The TTL field in the tag has the effect of preventing loops.

C.IBGP establishes a stable BGP neighbor relationship for the ARPback interface address.

D.Route switching between PE and CE can be static route, OSPF multi-instance, IS-iS multi-instance, EBGP.

Question 29

If the value of the Option field in the 0SPFv3 Hello packet sent by the GigabitEthermet 0/0/0 interface on the router is 0x000013, which of the following descriptions are correct? (Multiple Choice)

A.The router is an OSPFv3 device with forwarding capability.

B.Router A supports AS-External-LSA flooding

C.GigabitEthernct0/0/0 port of Router A belongs to the NSSA area.

D.Gigabit/thernet0/0/0 port of Router A will participate in IPv6 route calculation.

Question 30

Non-Stopping-Forwarding (NSF) and Non-Stopping Routing (NSR) are two solutions for high reliability. Which of the following statements are correct? (Multiple choice)

A.NSF routers do not need to support NSF through specific packet negotiation.

B.After the NSR is enabled, if the main control board fails when the service batch backup is not completed, the NR switch cannot be completed.

C.After the NSF is enabled, the router performs the master/slave switchover. The routing table and the forwarding table remain unchanged. Therefore, traffic is not lost during the GR time.

D.NSR routers need to negotiate NSR support through specific packet negotiation.
