Sample Questions — Cisco ENCOR (350-401)

5 free sample questions from this practice exam. Correct answers are highlighted.

1. An enterprise campus network uses HSRP between two distribution switches to provide default gateway redundancy for access-layer VLANs. Which HSRP router forwards traffic for the virtual IP address under normal operating conditions?

A The active router ✓ Correct
B The standby router
C The router in listen state
D The primary router

2. A network team is designing a campus network and wants to implement Stateful Switchover (SSO) on their distribution switches. Which primary benefit does SSO provide during a supervisor module failure on a redundant chassis switch?

A The standby supervisor takes over without interrupting traffic forwarding, providing hitless failover ✓ Correct
B SSO eliminates the need for redundant supervisor hardware by using software-based recovery
C SSO accelerates routing protocol reconvergence after a supervisor failure
D SSO prevents Spanning Tree topology changes during supervisor failover

3. A network engineer configures a GRE tunnel between two routers. After configuration, the tunnel interface comes up but the engineer observes that large packets are being dropped. Which GRE characteristic is the most likely cause?

A GRE does not support encryption, so large packets containing sensitive data are dropped by security policy
B GRE adds a 24-byte overhead that causes large packets to exceed the physical MTU, resulting in fragmentation or drops ✓ Correct
C GRE keepalives are failing, causing the tunnel to intermittently drop traffic for large flows
D GRE does not support IP multicast, so large multicast packets are discarded at the tunnel interface

4. A network engineer is configuring an EtherChannel between two Cisco switches. On Switch A, the ports are configured with `channel-group 1 mode active`. Which mode must be configured on Switch B for the EtherChannel to form using LACP?

A channel-group 1 mode desirable
B channel-group 1 mode auto
C channel-group 1 mode on
D channel-group 1 mode passive ✓ Correct

5. A network engineer is examining the OSPF neighbor states on a multi-access Ethernet segment. After DR/BDR election, which neighbor state is expected between two DROther routers on the same segment?

A Full
B 2-Way ✓ Correct
C ExStart
D Loading
