NEW QUESTION # 36
Click the Exhibit button.
A network administrator is investigating why traffic from R2 is not being forwarded to R1 Referring to the show isis database command output shown in the exhibit, what is causing this problem on the network?
- A. R1 and R2 are in different IS-IS areas.
- B. R2 is ignoring specific LSPs from R1 in its SPF calculations.

Answer: B
NEW QUESTION # 37
Exhibit:
CE-1, CE-2, and CE-3 are part of a single VPLS VPN An Ethernet frame has just arrived at PE-3 from CE-3. It has a source MAC address of CE-3 and a destination MAC address of CE-1. You want to know what PE-3 does with the Ethernet frame.
Referring to the exhibit, which statement is correct?
- A. It forwards the packet to PE-1 only.
- B. It drops the packet because the destination MAC address is not for PE-3.
- C. It forwards the packet to PE-1 and PE-2.
- D. It drops the packet because the destination MAC address is not in PE-3's MAC table.
Answer: C
Explanation:
The difference is that, for VPLS, packets can traverse the service provider networks in point-to-multipoint fashion, meaning that a packet originating from a CE device can be broadcast to all the PE routers participating in a VPLS routing instance. In contrast, a Layer 2 VPN forwards packets in point-to-point fashion.
NEW QUESTION # 38
Exhibit:
Referring to the exhibit, which two statements are true? (Choose two.)
- A. The route-distinguisher configuration allows routes to be shared between CE-1 and CE-2.
- B. The route-distinguisher configuration stops routes from being shared between CE-1 and CE-2.
- C. The vrf-target configuration stops routes from being shared between CE-1 and CE-2.
- D. The vrf-target configuration allows routes to be shared between CE-1 and CE-2.
Answer: A,C
NEW QUESTION # 39
You are creating an LDP-signaled Layer 2 circuit between two sites. Site1 and Site2 use different VLAN IDs to connect to your PE devices In this scenario, which encapsulation type must be used on the logical interfaces?
- A. vlan-vpls
- B. vlan-tcc
- C. vlan-ccc
- D. vlan-bridge
Answer: B
Explanation:
Configure the logical unit of the customer edge interface with a VLAN ID: NOTE:
The VLAN ID cannot be configured on logical interface unit 0. The logical unit number must be 1 or higher.
The same VLAN ID must be used when configuring the customer edge interface on the other PE switch.

Referring to the exhibit, which statement is correct?
- A. You should use VRF export policies on RR-1 to control which routes are sent to each PE router.
