質問72、 As shown in the figure, R1 and R2 form a VRRP backup group.

So which of the following descriptions about this backup group are correct? (Multiple choice)

The data of the three PCs is forwarded to the Internet via R2

The data of the three PCs is forwarded to the Internet via R1

質問73、 Which of the following descriptions about the Cluster List attribute in BGP is wrong?

When RR receives a BGP route carrying the Cluster_List attribute, and the attribute value contains the Cluster_ID of the cluster, RR considers that there is a loop in this route, so it will ignore the update about this route

The attribute is an optional transition type

Cluster_List is generated by the route reflector, which consists of a series of Cluster_ID

When a route is reflected by the reflector, the Cluster_ID of the RR will be added to the Cluster_List attribute of the route

質問74、 The following is the information output by a router through the display bgp routing-table command:
BGP Local router ID is 192.168.2.2 Status codes: *-valid, >-best, d-damped, h-history, i-internal, s- suppressed, S- Stale Origin: i-IGP, e-EGP, ? incomplete Total Number of Routes: 9 Network Next Hop MED LocPrfPrefVal Path/0gn*>1.1.1.9/32 0.0.0.0*)i 2.2.2.7/32 10.1 .1.2100 (65001)i 1.3.1 1000 (6501165001)i*i 1.2.2100 (65011)i*>i

質問85、 On the OSPF network shown in the figure, R1, R2, and R3 run OSPF, and R1 advertises four VPN routes to OSPF. A filter-policy needs to achieve the following goal: R1’s and R3’s routing tables contain the routes to 192.168.3.0/24, but R2’s routing table does not. Which of the following filter-policies cannot meet this requirement?

A filter-policy on R2 for filtering received routes

A filter-policy on R2 for filtering the routes to be advertised

A filter-policy on R1 for filtering the routes to be imported

A filter-policy on R1 for filtering the imported routes to be advertised

質問86、 During BGP route summarization configuration, the keyword can be used to suppress all specific routes so that only the summary route is advertised. The summary route carries the Atomic-aggregate attribute rather than the community attributes of specific routes.

質問87、 Which of the following descriptions about VRRP load sharing is correct? (Multiple choice)

Load sharing means that multiple VRRP backup groups undertake business at the same time

Multi-gateway load sharing is to achieve load sharing by creating multiple VRRP backup groups with virtual IP addresses and specifying different VRRP backup groups as gateways for different users
