172.1.8.0/21.
Question302: Which of the following statements about OSPF authentication are false? (Choose two.)
Question303: Which command must be configured to establish a BGP peer relationship between indirectly connected EBGP peers?
Question304: Route filtering can filter not only routing information but also link-status information.
Question305: On a broadcast network or an NBMA network, not all neighbors need to set up adjacencies. Therefore, the concept about the adjacency is applicable to only the broadcast network or the NBMA network.
Question306: A Router ID is optional in the OSPF configuration.
Question307: Which of the following route selection mechanisms can adopt user-defined policies to determine data forwarding paths flexibly based on ACLs or packet lengths?
Question308: Which of the following statements about the Monitor Link group is false?
Question309: How many hosts are available per subnet if apply a /21 mask to the class B network?

Which of the following is the possible cause?

Question312: Which of the following statements about LACP are true? (Choose two.)
Question313: Which methods can be used to import local routes to BGP? (Choose two.)
Question314: The import-route limit command is used to set the maximum number of external routers that can be imported into an OSPF process.
Question315: What is the link ID of an ASBR-Summary-LSA?
Question316: In OSPF protocol, which of the following elements are used to describe one link? (Choose three.)
Question317: Policy-based routing and routing policy affect the forwarding of data packets in different ways: A routing policy mainly controls packet forwarding. According to the routing policy, packets can be forwarded with no need to use a routing table; policy-based routing mainly controls the importing, advertising, and receiving of routing information so as to affect the forwarding of data packets.
Question318: Which BGP attribute is not a well-known mandatory attribute?
Question319: Which of the following commands is used to display the IGMP routing table?
Question320: Which of the following routes matches the ACL filter given below?
"ad number 2001
rule 0 permit source 1.1.0.0 0"
Question321: After the session is re-established between the BGP GR helper and its neighbor, original forwarding entries are deleted.
Question322: Which of the following statements about state transition are true? (Choose three.)

Question324: Which switching technology reduces the size of broadcast domain?
Question325: Which of the following statements about VRRP are true? (Choose three.)
Question326: Based on BGP route selection rules, a local route that is automatically summarized takes precedence over a local route that is manually summarized.
Question327: Which BGP attributes are optional in a BGP Update packet? (Choose two.)
Question328: Default routes between routers are a low-cost solution. This is because using default routes requires less system resources than maintaining a complete routing table.
