Click the Exhibit button.

 

You notice that there is a problem with the OSPF adjacency between two routers, R1 and R2. The relevant system logs from R1 are shown in the exhibit.

 

What would cause this behavior?

 

A.

R2 was dropping R1’s OSPF hello packets.

B.

R1 was dropping R2’s OSPF hello packets.

C.

R1’s interface went down and came back up.

D.

There is an OSPF hello timer mismatch between the two routers.

 

Answer: A

A.

The classifier does not contain a mapping for this precedence value.

B.

The classifier is assigning the traffic a high loss priority.

C.

The classifier is assigning the traffic to the best-effort forwarding class.

D.

The classifier is dropping the traffic.

Click the Exhibit button.

 

 

 

 

You are trying to establish an OSPF adjacency between R1 and R2, but the adjacency does not establish.

 

Referring to the exhibit, what is causing the adjacency to fail?

 

A.

The MD5 key ID values are mismatched between R1 and R2.

B.

R1 has both family inet and family iso configured on the link toward R2.

C.

The IP subnet mask is mismatched between R1 and R2.

D.

The interface type is mismatched between R1 and R2.

 

Answer: D

 

 

QUESTION 7  

 

policy-options {

 

policy-statement accept-static {

 

from protocol static;

 

then accept;

 

}

 

}

 

 

Click the Exhibit button.

 

The policy shown in the exhibit is deployed on a router and used as the only BGP export policy. The router is sending only one BGP route to its peers. However, when you run the CLI command test policy accept-static 0.0.0.0/0, the policy matches thousands of routes.

 

Which statement explains this discrepancy?

 

A.

All policies have an implicit then accept final term.

B.

The default policy for BGP is to reject all routes.

C.

The default policy for the test policy command is to accept all routes.

D.

The test policy command always shows all routes, regardless of whether they match the

 

 

 

 

policy, when you use the 0.0.0.0/0 argument.

 

Answer: C

 

 

QUESTION 8

You are troubleshooting a problem where an OSPF adjacency between two neighboring routers will not form.

 

What are two reasons for this problem? (Choose two.)

 

A.

One or both of the connected interfaces are missing the family inet statement.

B.

One or both of the connected interfaces are missing the family iso statement.

C.

The connected interfaces are not on the same subnet.

D.

Another IGP is running on one or both of the routers, overriding OSPF.

 

Answer: BD

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 high loss priority.

B.

The BA classifier is assigning the traffic to the best-effort queue with a low loss priority.

C.

The BA classifier is assigning the traffic to the expedited forwarding queue with a high loss priority.

D.

The BA classifier is assigning the traffic to the expedited forwarding queue with a low loss priority.

 

Answer: D

 

 

QUESTION 10

Your Layer 2 network uses VLAN IDs 100 through 400 and you are required to load- balance these VLANs between two different root bridges. You are currently using the default RSTP settings and notice that all VLANs are using the same root bridge.

 

How do you ensure the VLANs are load-balanced between two root bridges?

 

A.

Configure MSTP with two MSTI reg
ions and split the VLAN range between them.

B.

Configure VSTP with two VLAN groups and split the VLAN range between them.

C.

Configure two RSTP instances and split the VLAN range between them.

D.

Configure STP and RSTP and split the VLAN range between them.
