Click the Exhibit.

You have deployed the access control configuration to the distribution switch.
Referring to the exhibit, which statement is true?

A. Only the first host to authenticate will have access to the network; other hosts will be blocked.

B. All hosts connected to the access switch will have access to the network without authentication.

C. All hosts connected to the access switch will have access to the work after one device authenticates.

問題2

Click the Exhibit.

Referring to the exhibit, you have EBGP peerings with both ISP1 and ISP2. You are receiving the
172.25.12.0/24, 172.25.13.0/24, 172.25.14.0/24, and 172.25.15.0/24 routes through both neighbors. You must ensure that traffic to these prefixes are load balances through both service providers. You have configured a load-balancing policy and have applied it to the forwarding table, but the prefixes are not being load balanced.
What is required to accomplish this task?

A. The multihop feature should be enabled between both neighbors.

B. The multipath multiple-as feature should be used between both neighbors.

C. The as-override feature should be used between both neighbors.

D. The include-mp-next-hop feature should be used between both neighbors.

正確答案: B

B. Create and apply an import policy to set the route preference on routes learned from ISP2 to be lower than those learned from ISP1.

C. Create and apply an import policy to set the route preference on routes learned from ISP2 to be higher than those learned from ISP1.

D. Create and apply an import policy to set the local preference on routes learned from ISP2 to be higher than those learned from ISP1.

正確答案: D
