Traffic flows through your network, as shown in the exhibit. You have configured a rewrite rule on R1 to mark HTTP traffic with a specific DSCP value.

What must you do to ensure that the HTTP traffic preserves its DSCP value as it leaves your CoS domain?

  1. Use behavior aggregate classifiers mapping the HTTP traffic to the specific DSCP value on R1 and R2.

  2. Use rewrite rules mapping the HTTP traffic to the specific DSCP value on R2 and R3.

  3. Use a rewrite rule mapping the HTTP traffic to the specific DSCP value on R3.

  4. Use the default settings already in place on the device.

Your company is integrating another OSPF area into your existing OSPF infrastructure. You created a virtual link that spans Area 2 and connects Area 3 to the backbone area.

Based on the exhibit, what is preventing the adjacency?

  1. The interface configured for the virtual link is incorrect. It should be a vt and not a vl interface.

  2. No designated router (DR) has been elected.

  3. The backup route to Area 2 has not been configured.

  4. The wrong transit area is configured.
