Question

A Network Management Station (NMS) is using SNMP to manage some Cisco routers and switches with SNMPv2c. Which of the following answers most accurately describes how the SNMP agent on a router authenticates any SNMP Get requests received from the NMS?a. Using a username and hashed version of a password
b. Using either the read-write or read-only community string
c. Using only the read-write community string
d. Using only the read-only community string

Answer 1

Answer:

b. Using either the read-write or read-only community string.

Explanation:

The SNMP agent on a router authenticates any SNMP Get requests received from the NMS using either the read-write or read-only community string.

In the SNMPv2c, if the NMS sends either the read-write or read-only community string requests, SNMP Get requests will be allowed.

Answer 2

Answer:

A. Using a username and hashed version of password

Explanation:

SNMP v2 allows password hashing with MD5, unlike the early versions SNMP v1 which sends passwords in clear-text over the network which allows packet sniffing to read the password, but the password hashing has to be configure n SNMP v2.

Therefore using a username and hashed version of a password would be most accurately describes how the SNMP agent on a router authenticates any SNMP Get requests received from the NMS.
