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.

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?
To resolve the issue, configuring all devices for SNMPv3 informs with priv is the correct action. SNMPv3 informs are reliable because they require an acknowledgment from the recipient device, ensuring that the notification has been received. The 'priv' option in SNMPv3 provides encryption, securing the data being transmitted. Thus, using SNMPv3 informs with priv will ensure that notifications are both reliable and encrypted.
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.
B is correct. "informs" is "reliable"
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

B is correct
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
B is my choice
The given answer is correct
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
Nice, thanks for pointing this out!
The given answer is correct
The router configured to "send" out something is "TRAP". Auth makes it reliable and Priv makes it confidential ... Answer is D.
Not true, reliable means he waits for a response from the NMS. Traps are not reliable. Informs are.
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
sorry D
should not be B
