Cisco ENCOR Cisco ENCOR 350-401 Trivia 4 — Questions and Answers
Question 1: Which Python data structure is best suited to store YANG-modeled configuration data retrieved via NETCONF?
- List
- Dictionary (dict) (Correct answer)
- Tuple
- Set
Correct answer: Dictionary (dict)
NETCONF returns XML that maps naturally to nested Python dictionaries when parsed with libraries like xmltodict or ncclient.
Question 2: In Cisco SD-WAN (Viptela), which component distributes OMP routing updates between vEdge/cEdge routers?
- vManage
- vBond
- vSmart (Correct answer)
- vAnalytics
Correct answer: vSmart
The vSmart controller runs OMP (Overlay Management Protocol) and acts as the route reflector for all SD-WAN edge devices.
Question 3: What is the maximum number of equal-cost paths that OSPF supports for load balancing by default on Cisco IOS?
- 4 (Correct answer)
- 6
- 8
- 16
Correct answer: 4
OSPF defaults to 4 equal-cost paths for load balancing, though this can be increased with the 'maximum-paths' command.
Question 4: Which type of EVPN BGP route is used to advertise MAC and IP binding information learned from a local host?
- Route Type 1 (Ethernet Auto-Discovery)
- Route Type 2 (MAC/IP Advertisement) (Correct answer)
- Route Type 3 (Inclusive Multicast)
- Route Type 5 (IP Prefix)
Correct answer: Route Type 2 (MAC/IP Advertisement)
EVPN Route Type 2 carries MAC address and optional IP address bindings to enable L2 reachability across VXLAN fabric.
Question 5: Which Cisco security feature inspects traffic at Layer 7 and can block specific application signatures regardless of port?
- ACL
- NBAR2 (Correct answer)
- Port Security
- DAI
Correct answer: NBAR2
Network-Based Application Recognition 2 (NBAR2) performs deep packet inspection at Layer 7 to classify applications by signature, not just port.
Question 6: What happens to OSPF adjacency when two routers on the same link have mismatched MTU settings?
- Adjacency forms normally but routes may not be exchanged
- Adjacency gets stuck in EXSTART/EXCHANGE state (Correct answer)
- Adjacency forms but the link cost doubles
- Adjacency is rejected at the INIT state
Correct answer: Adjacency gets stuck in EXSTART/EXCHANGE state
MTU mismatch causes OSPF to fail during the database exchange phase, leaving adjacency stuck in EXSTART or EXCHANGE state.
Question 7: In a Cisco FlexConnect deployment, which forwarding mode allows the AP to switch traffic locally without sending it to the WLC?
- Central switching
- Local switching (Correct answer)
- Monitor mode
- Sniffer mode
Correct answer: Local switching
FlexConnect local switching allows the AP to forward traffic directly to the local network without tunneling it back to the WLC.
