NEW QUESTION # 71
Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.
Which action would solve this problem?
- A. Disable the BPDU block function on the distribution switch.
- B. Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
- C. Disable the BPDU block function on the access switches.
- D. Configure the links between the access switches and the distribution switch as a trunk port.
Answer: D
Explanation:
Access interfaces in an L2PT-enabled VLAN should not receive L2PT-tunneled PDUs. If an access interface does receive L2PT-tunneled PDUs, there might be a loop in the network, and the device will shut down the interface.

You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.
Which statement is correct in this scenario?
- A. MVRP works with RSTP and VSTP.
- B. When enabled, MVRP affects all interfaces.
- C. The forbidden mode does not register or declare VLANs.
- D. Timers dictate when link state changes are propagated.
Answer: C
Explanation:
MVRP is disabled by default on the switches and, when enabled, affects only trunk interfaces.
Once you enable MVRP, all VLAN interfaces on the switch belong to MVRP (the default normal registration mode) and those interfaces accept PDU messages and send their own PDU messages.
forbidden - The interface does not register or declare VLANS (except statically configured VLANs).
