An NMS is unable to poll an IOS XE router using SNMPv2c with community string 'monitor'. The engineer verifies that the community string is configured correctly and the NMS IP is reachable. What is the most likely cause of the polling failure?

The SNMP agent is not enabled on the router

The NMS is using SNMPv3 instead of SNMPv2c

The ACL applied to the community string does not permit the NMS IP

The router's SNMP port is blocked by a firewall

An engineer is troubleshooting why an NMS cannot poll an IOS XR router via SNMPv2c. The engineer runs 'show snmp' and sees that the SNMP agent is enabled. What should the engineer check next?

Check the SNMPv3 user configuration

Verify the community string and any associated ACL

Verify the router's routing table

An engineer is troubleshooting SNMPv3 authentication failures on an IOS XE router. The 'show snmp user' output shows the user 'monitor' with authPriv and SHA/AES. The NMS is configured with the same username, but authentication still fails. What should the engineer check next?

Check the SNMP community string

Verify the authentication and privacy passwords on both sides

Verify the router's routing table

What is the key difference between SNMP traps and informs?

Traps are sent over TCP, while informs are sent over UDP.

Informs are acknowledged by the receiver, while traps are not.

Traps are only sent for critical events, while informs are for informational events.

Informs are only supported in SNMPv1, while traps are supported in all versions.

What is the purpose of applying an access list to an SNMPv2c community string on a Cisco IOS XR device?

To define the trap receiver for the community.

To specify which MIB objects the community can access.

To restrict which network management stations can use the community string.

To encrypt the community string in transit.
