An engineer configured a Cisco router to send reliable and encrypted notifications for any events to the management server. It was noticed that the notification messages are reliable but not encrypted. Which action resolves the issue?
A.
Configure all devices for SNMPv3 informs with auth.
B.
Configure all devices for SNMPv3 informs with priv.
C.
Configure all devices for SNMPv3 traps with auth.
D.
Configure all devices for SNMPv3 traps with priv.
B The "inform" message is a type of SNMPv3 notification that requires an acknowledgment from the recipient device, making it a reliable way of transmitting information. The "priv" option in SNMPv3 provides encryption of the data being transmitted, ensuring that the information is secure and cannot be intercepted by unauthorized users.
summary of Informs and traps:
Both use DEST port 162 udp (Router to NMS)
Informs - request for acknowledgement to the NMS (more critical events)
- more reliable than trap messages since acknowledgement required by NMS
Traps - "fire and forget" (less critical events)
- less overhead
Priv(privacy) - encryption (DES, AES) that is supported in SNMP version 3
I think B i correct:
The following example shows how to configure a remote user to receive traps at the “noAuthNoPriv” security
level when the SNMPv3 security model is enabled:
Device(config)# snmp-server group group1 v3 noauth
Device(config)# snmp-server user remoteuser1 group1 remote 10.12.8.4
Device(config)# snmp-server host 10.12.8.4 informs version 3 noauth remoteuser config
The major difference between an inform request and a trap is that an SNMP agent has no way of knowing if an SNMP trap was received by the SNMP manager. However, an SNMP inform request packet will be sent continually until the sending SNMP manager receives an SNMP acknowledgement.
"Reliable" is stated clearly in the question
The answer should be B because the major difference between an inform request and a trap is that an SNMP agent has no way of knowing if an SNMP trap was received by the SNMP manager. However, an SNMP inform request packet will be sent continually until the sending SNMP manager receives an SNMP acknowledgement. The keyword is "reliable" here
Actually B is right since Inform packets are performed for events in SNMP, while traps are independent sents from agent to manager. But I guess the trick is in the word event
