Cisco ENCOR 350-401 Trivia Flashcards

Which LISP component is responsible for mapping endpoint identifiers (EIDs) to routing locators (RLOCs)?

Answer: Map-Server

The LISP Map-Server stores and resolves EID-to-RLOC mappings, responding to queries from Ingress Tunnel Routers.

What does the ENCOR exam topic 'network assurance' primarily involve using Cisco DNA Center for?

Answer: Proactive monitoring and AI-driven insights

Cisco DNA Center Network Assurance uses AI/ML to proactively monitor network health and provide actionable insights.

Which 802.11 feature allows a wireless client to roam between APs without re-authenticating by caching PMK keys?

Answer: 802.11r (Fast BSS Transition)

802.11r Fast BSS Transition pre-caches PMK security keys on neighboring APs, dramatically reducing roaming latency.

In EIGRP, what is the Feasible Condition (FC) used to determine?

Answer: Whether a successor route is loop-free

The Feasible Condition ensures a feasible successor's reported distance is less than the current successor's feasible distance, guaranteeing a loop-free alternate path.

Which virtualization technology allows multiple logical routers to share the same physical hardware while maintaining completely separate routing tables?

Answer: VRF

Virtual Routing and Forwarding (VRF) creates multiple independent routing table instances on a single physical device.

What is the primary function of NETCONF compared to SNMP for network management?

Answer: NETCONF provides transactional configuration with rollback support

NETCONF provides transactional configuration management with commit/rollback capabilities over SSH, which SNMP lacks.

Which VXLAN component is responsible for handling BUM (Broadcast, Unknown unicast, Multicast) traffic in an ingress replication model?

Answer: VTEP flood list

In VXLAN ingress replication, each VTEP maintains a flood list of remote VTEPs and replicates BUM traffic to each peer unicast.
