Cisco ENCOR Cisco ENCOR 350-401 MCQ 2 — Questions and Answers
Question 1: Which OSPF network type is used by default on a point-to-point serial link?
- Broadcast
- Non-broadcast
- Point-to-point (Correct answer)
- Point-to-multipoint
Correct answer: Point-to-point
OSPF defaults to the point-to-point network type on serial links, eliminating the need for DR/BDR election.
Question 2: In SD-Access, which component serves as the control plane node managing LISP map-server and map-resolver functions?
- Border node
- Edge node
- Fabric wireless LAN controller
- Control plane node (Correct answer)
Correct answer: Control plane node
The control plane node in SD-Access runs the LISP map-server and map-resolver, maintaining the endpoint-to-RLOC mapping database.
Question 3: What is the default administrative distance of an EIGRP internal route?
- 90 (Correct answer)
- 110
- 100
- 70
Correct answer: 90
EIGRP internal routes have an administrative distance of 90, making them preferred over OSPF (110) but less preferred than static routes (1).
Question 4: Which QoS mechanism is used to prevent a single traffic flow from monopolizing bandwidth through token consumption limits?
- Weighted Fair Queuing
- Policing (Correct answer)
- Shaping
- CBWFQ
Correct answer: Policing
Policing drops or re-marks traffic that exceeds the configured rate, immediately discarding excess tokens without buffering.
Question 5: In VXLAN, what is the role of the VTEP (VXLAN Tunnel Endpoint)?
- Routes packets between different VNIs
- Encapsulates/decapsulates Layer 2 frames in UDP packets (Correct answer)
- Provides control plane signaling via LISP
- Manages multicast group membership
Correct answer: Encapsulates/decapsulates Layer 2 frames in UDP packets
The VTEP encapsulates Layer 2 Ethernet frames into UDP/IP packets for transport across the Layer 3 underlay network.
Question 6: Which Spanning Tree Protocol feature allows a port to immediately transition to forwarding state when connected to an end device?
- Root Guard
- BPDU Guard
- PortFast (Correct answer)
- Loop Guard
Correct answer: PortFast
PortFast bypasses the STP listening and learning states, allowing an edge port to immediately enter forwarding state.
Question 7: What does the BGP attribute MED (Multi-Exit Discriminator) influence?
- How traffic exits the local AS to a neighbor AS
- How external neighbors send traffic into your AS (Correct answer)
- The preference of routes within the local AS
- The weight assigned to a BGP session
Correct answer: How external neighbors send traffic into your AS
MED is a non-transitive attribute sent to external neighbors to suggest the preferred entry point into your autonomous system.
