Practise exhibit-style questions that ask you to read a topology, table, command output or diagram before choosing the best answer.
Start Scenario PracticeRefer to the exhibit. The router has three LDP neighbors established. A network administrator notices that MPLS labels for the prefix 10.4.4.0/24 are not being advertised from this router to its neighbors, although the prefix is present in the routing table. Which is the most likely cause?
Explanation: LDP only advertises labels for prefixes that are the best path in the routing table (unless label advertisement is configured for all routes). If 10.4.4.0/24 is present but not the best path (e.g., a backup route or a route with a higher administrative distance), LDP will not allocate and advertise a label for it. This matches the symptom of the prefix being in the table but no label being advertised.
Which MEF Carrier Ethernet service type is used for a rooted-multipoint topology, where a single root site communicates with multiple leaf sites but leaf sites cannot communicate directly?
Explanation: E-Tree (Ethernet Tree) is a rooted-multipoint service where the root can communicate with leaves, but leaves cannot communicate with each other.
Refer to the exhibit. The router has an outgoing label of 'Pop' for prefix ***********. What does this imply?
Explanation: When a router has an outgoing label of 'Pop' for a prefix in MPLS, it indicates that the router is the penultimate hop (PHP) in the LSP. PHP means the router will remove (pop) the top label before forwarding the packet to the next hop, reducing the burden on the egress LSR. This is standard MPLS behavior as per RFC 3031, where the egress router signals an implicit null label (label 3) to its upstream neighbor.
Refer to the exhibit. A PE router is showing a VRF route. What does the [200/0] indicate?
Explanation: In the VRF route output, the [200/0] notation represents the administrative distance (200) and the metric (0) for the route. The administrative distance is a trustworthiness value used by the router to select the best path when multiple routing protocols provide routes to the same destination; a lower value is preferred. The metric is a protocol-specific cost, and here it is 0, indicating a directly connected or very low-cost path within the VRF.
Based on the exhibit, which statement is true about the QoS policy?
Explanation: The exhibit shows a QoS policy where the VOICE class is configured with the 'priority' command and a bandwidth statement of 10 percent. In Cisco IOS, the 'priority' command under a class map creates a strict priority queue (LLQ), and the bandwidth percentage defines the maximum amount of interface bandwidth that can be used by this queue, ensuring low-latency treatment for voice traffic. Therefore, option C is correct.
