Question 62

Is the following information about BGP4+ described correctly?

BGP4 can use dampening commands to suppress oscillations on IBGP routes.

Modifying the RouterID of BGP causes the BGP connection between routers to be re-established.

The Next Hop attribute in BGP4+ is represented by an IPv6 address, which can be the link-local address of the next hop.

BGP4+ does not support route auto-aggregate

Question 63

Is the following description of ospf virtual links correct?

A virtual connection can be established in any area, after which it itself belongs to the region

The virtual connection ip is used as the link address

Virtual links can be used to solve the problem of zone 0 being segmented

The cost of a virtual connection is zero and is the optimal link

Question 64

What kind of scenario can use AS one path and one filter?

Filter routes received from BGP neighbors based on the AS PATH attribute that the route carries.For example, the command peer x.X.x.x as path-filter import

The apply clause in Routepolicy

Filter routes sent to BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peerx. X.x.x as path-filter export

If-natch clause answer in Route-policy.

Question 65

Without dividing the zone, is the following description of the link state routing protocol correct?

Each router establishes a topology for the entire floodplain

Each router learns route entries directly from the route update and adds them to the routing table

Routers in the flood domain may receive the same link state information repeatedly

Routers throughout the flood domain have the same database of wrong-state states

The router will send all the mis-routing status information from one neighbor to all other neighbors to ensure the synchronization of the database

If the OSPP protocol is running in the network , after configuring the non-backbone area in the OSPP area as the Totally Stub region, the ABR router sends a message to Totally. The Stub region issues an LSA with an LS ID of 0000, and what type of LSA is the LAS to?

LSA5

LSA2

LSA1

LSA3

Question 67

If an administrator wants to manage certain routes on the router during operations, the following tools are listed below. These routes can be flagged so that administrators can configure policies

If the BGP protocol is running, the route is marked with the community attribute

Use ACLs to tag routes on the router.

Use the Tag value to mark the route on the router.

Use ipprefix to tag routes on the router.

Question 68

An existing router running BGP, HW1, has both IBGP neighbors and EBGP neighbors configured on the router. Are the IP Neighbors and EBGP Neighbors described below correctly?

The router will be connected directly from its EBGP IBGP neighbor, otherwise, IBGP-Multi-hop must be configured

The router sends BGP updates learned from its EBGP neighbors to its other IBGP neighbors and EBGP neighbors

IBGP neighbors can establish neighbor relationships through Loopback engagements

The router sends BGP updates learned from its IBGP neighbors to its other IBGP neighbors and EPGP neighbors

EBGP neighbors must be directly connected, otherwise, EBGP-Multi-hop must configure
