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 show command output displays the LDP neighbor state. What does the 'Downstream' label mode indicate about label distribution?
Explanation: In the context of LDP, 'Downstream' label mode means that a router advertises label bindings for all prefixes in its routing table to its LDP neighbors without waiting for an explicit request. This is the default label distribution mode for LDP, where labels are proactively sent to all peers. Option D correctly identifies this behavior.
Refer to the exhibit. Which statement about this BGP configuration is true?
Explanation: The `next-hop-self` command under the VRF address-family instructs the PE router to set its own IP address as the next-hop for routes advertised to the route reflector. This is necessary in MPLS L3VPN environments to ensure that the route reflector (and other PEs) can reach the customer prefix via the advertising PE, avoiding reachability issues when the original next-hop is not directly connected across the MPLS core.
A service provider is deploying a new MPLS core with Segment Routing and requires fast convergence upon link failure. They plan to use TI-LFA (Topology Independent Loop-Free Alternate). What is a prerequisite for TI-LFA to provide protection against any single link failure?
Explanation: TI-LFA relies on the IGP having a complete view of the network topology to compute a post-convergence path that avoids the failed link. OSPF and IS-IS are link-state protocols that flood link-state advertisements (LSAs) or link-state packets (LSPs) to provide this full topology database, which is essential for TI-LFA to calculate a loop-free backup path for any single link failure.
Refer to the exhibit. An engineer pushes this XML configuration via NETCONF, but the device rejects it with an error stating 'invalid policy-map structure'. What is the problem?
Explanation: The error 'invalid policy-map structure' occurs because the policy-map references a class name that has not been defined in a class-map beforehand. In Cisco IOS, a class-map must exist before it can be used inside a policy-map; otherwise, the device rejects the configuration as structurally invalid.
Based on the exhibit, what is the purpose of the 'mpls ldp neighbor ... password cisco' commands?
Explanation: The 'mpls ldp neighbor ... password cisco' command configures a Message Digest 5 (MD5) authentication password for the LDP session with a specific neighbor. This ensures that the TCP connection used for LDP exchanges is authenticated, preventing spoofed or unauthorized LDP messages from being accepted, as defined in RFC 5036.
