Question 1

On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router.
Both R1 and R4 have static routes to 192.168.1.0/24 , which are imported to BGP using the import-route command.
R1 adds a community attribute (1:1) to the route when sending it to peers.
All routers are enabled to transmit the community attribute .
Routing policies are configured on R2 and R3 to reject routes with community 1:1 .
In this case, which of the following is the path for traffic from R3 to 192.168.1.0/24?

A. R3 # R2 # R4 B. R3 does not have a route to 192.168.1.0/24 C. R3 # R2 # R1 D. R3 # R5 # R1

Question 2

VLAN aggregation uses multiple sub-VLANs to isolate broadcast domains on a physical network and aggregates these sub-VLANs into a logical super-VLAN. Which of the following statements is true about VLAN aggregation?

A. If different sub-VLANs belong to the same super-VLAN, hosts in these sub-VLANs can directly communicate at Layer 2. B. If a super-VLAN and the corresponding VLANIF interface are created on a core switch, the VLANIF interface goes Up as long as there is a physical interface in Up state on the core switch. C. If proxy ARP is enabled on the VLANIF interface corresponding to a super-VLAN, ARP entries can be generated to allow all sub-VLANs to communicate. D. When configuring VLAN aggregation, you can configure VLAN 1 as a super-VLAN.

Question 5

On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router. Both Rl and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command. R3 is configured with the peer y.y.y.y as-path-filter 1 import command for all peers. Which of the following sets of commands enables R3 to select the route with the longest AS_Path to 192.168.1.0/24?

A. ip as-path-filter 1 deny 65001s ip as-path-filter 1 permit .* B. ip as-path-filter 1 permit .* ip as-path-filter 1 deny 65001s ip as-path-filter 1 deny A65005 C. jp as-path-filter 1 deny .*6500 ip as-path-filter 1 permit .* D. ip as-path-filter 1 deny A65002 ip as-path-filter 1 deny A65005 ip as-path-filter 1 permit .*

Question 8

On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?

A. If the link between R2 and SI is disconnected, R1 recalculates the optimal path to R3 and performs path switching instantly. B. If the link between R1 and SI is disconnected and you check neighbor information on R1, the neighbor relationship between R1 and R2 will instantly display Down. C. If the link between R1 and SI is disconnected, Rl recalculates the optimal path to R3 and performs path switching instantly. D. If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3 because FRR is enabled on R1.
