Cisco ENCOR Cisco ENCOR 350-401 Trivia 3 — Questions and Answers
Question 1: Which LISP component is responsible for mapping endpoint identifiers (EIDs) to routing locators (RLOCs)?
- ITR
- ETR
- Map-Server (Correct answer)
- PxTR
Correct answer: Map-Server
The LISP Map-Server stores and resolves EID-to-RLOC mappings, responding to queries from Ingress Tunnel Routers.
Question 2: What does the ENCOR exam topic 'network assurance' primarily involve using Cisco DNA Center for?
- Static route redistribution
- Proactive monitoring and AI-driven insights (Correct answer)
- BGP route reflector configuration
- Manual VLAN provisioning
Correct answer: Proactive monitoring and AI-driven insights
Cisco DNA Center Network Assurance uses AI/ML to proactively monitor network health and provide actionable insights.
Question 3: Which 802.11 feature allows a wireless client to roam between APs without re-authenticating by caching PMK keys?
- 802.11r (Fast BSS Transition) (Correct answer)
- 802.11k (Radio Resource Management)
- 802.11v (BSS Transition Management)
- 802.11w (Management Frame Protection)
Correct answer: 802.11r (Fast BSS Transition)
802.11r Fast BSS Transition pre-caches PMK security keys on neighboring APs, dramatically reducing roaming latency.
Question 4: In EIGRP, what is the Feasible Condition (FC) used to determine?
- Whether a route should be redistributed
- Whether a successor route is loop-free (Correct answer)
- Whether a neighbor relationship is active
- Whether summarization should occur
Correct 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.
Question 5: Which virtualization technology allows multiple logical routers to share the same physical hardware while maintaining completely separate routing tables?
- VRF (Correct answer)
- VLAN
- VPC
- VSS
Correct answer: VRF
Virtual Routing and Forwarding (VRF) creates multiple independent routing table instances on a single physical device.
Question 6: What is the primary function of NETCONF compared to SNMP for network management?
- NETCONF uses UDP while SNMP uses TCP
- NETCONF provides transactional configuration with rollback support (Correct answer)
- NETCONF only supports read operations
- NETCONF requires more bandwidth than SNMP
Correct answer: NETCONF provides transactional configuration with rollback support
NETCONF provides transactional configuration management with commit/rollback capabilities over SSH, which SNMP lacks.
Question 7: Which VXLAN component is responsible for handling BUM (Broadcast, Unknown unicast, Multicast) traffic in an ingress replication model?
- VTEP flood list (Correct answer)
- Multicast group mapping
- EVPN Route Type 3
- ARP suppression table
Correct 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.
