-- Exhibit -Click the Exhibit button. You are asked to assist with a problem with a new EBGP peering between Site 1 and Site
2. Referring to the exhibit, Site 1 is not receiving the 100.100.0.0/16 routes from Site 2. Which action will resolve the problem?
A. Enable the advertise-inactive parameter for the EBGP peering.
B. Enable the as-override parameter for the EBGP peering.
C. Create an export policy to export the IBGP routes over the EBGP peering.
D. Create a next-hop-self policy and apply it as an export policy to the EBGP peering.
正解：A

Click the Exhibit button.
Traffic with the IP precedence value af21 ingresses the router and should be rewritten with the same value as it egresses; however, this traffic is rewritten to a different value.
Referring to the exhibit, what is the source of this problem?
A. The BA classifier is assigning the traffic to the best-effort queue with a low loss priority.
B. The BA classifier is assigning the traffic to the expedited forwarding queue with a high loss priority.
C. The BA classifier is assigning the traffic to the best-effort queue with a high loss priority.
D. The BA classifier is assigning the traffic to the expedited forwarding queue with a low loss priority.
正解：D

質問 3：
You are having problems redistributing RIP routes into OSPF. Your Junos device has the following configuration:
[edit protocols ospf]
user@router# show
import my-policy;
area 0.0.0.0 {
interface ge-0/0/0.0;
interface ge-0/0/ ;
interface ge-0/0/ {
passive;
}
}
What would resolve the problem?
A. Apply my-policy as an export policy under the [edit protocols rip] hierarchy.
B. Apply my-policy as an export policy under the [edit protocols ospf] hierarchy.
C. Use the area-range parameter instead of a routing policy.
D. Apply my-policy as an import policy under the [edit protocols rip] hierarchy.
正解：C

質問 4：
You want to receive routes from a remote EBGP peer as shown in the exhibit. The remote site has the same AS number as your own. You have successfully established the EBGP peering, but are not receiving any routes.
Which BGP group configuration parameter will enable you to receive routes from the remote EBGP peer?

A. as-override
B. multipath
C. remove-private
D. advertise-inactive
正解：A

Click the Exhibit button.
You are sending traffic to the ge-0/0/0 interface on R1 with the expedited forwarding (101) IP precedence bits. However, the counters on the router show that it is not processing any traffic in the expedited forwarding queue.
Referring to the exhibit, what is causing the problem?
A. The classifier is assigning the traffic to the best-effort forwarding class.
B. The classifier is dropping the traffic.
C. The classifier does not contain a mapping for this precedence value.
D. The classifier is assigning the traffic a high loss priority.
