  A. With STP, a designated port can transition to the forwarding state without waiting for the protocol times to expire.

  B. STP uses point-to-point and edge port designations.

  C. With RSTP, a designated port can transition to the forwarding state without waiting for the protocol times to expire.

  D. RSTP uses point-to-point and edge port designations.

  Correct Answer: CD

• Question 17:

  Click the Exhibit button.

  

  You have created a GRE tunnel as shown in the exhibit. The router with tunnel endpoint A is dropping the packets originating from User A and destined to User B.

  What would cause this problem?

  A. Endpoint A has the internet-options gre-path-mtu-discovery parameter enabled.

  B. User A requested fragmentation and Endpoint A has the clear-dont-fragment-bit parameter enabled.

  C. Endpoint A is missing a policy statement that allows User A's traffic into the tunnel.

  D. User A is sending maximum size default Ethernet frames with the DF bit enabled.

  Correct Answer: D

• Question 18:

  What are two functions of bridging? (Choose two.)

  A. blocking

• Question 20:

  Each PC and IP phone in your network is connected to a switch using the same port. All incoming data traffic is untagged and belongs to the v10 VLAN, while traffic coming from the IP phones is tagged with a VLAN value of 20 and should belong to the v20 VLAN on your switch.

  In this scenario, which statement is correct?

  A. You must enable the voice VLAN feature on the incoming interfaces and assign the v20 VLAN.

  B. You must enable an IRB interface and assign it to the v10 and v20 VLANs.

  C. You must enable LLDP-MED on the incoming interfaces and assign the v20 VLAN.

  D. You must enable the guest VLAN feature on the incoming interfaces and assign the v20 VLAN.

  Correct Answer: A
