Question 6: A technician has finished configuring AAA on a new network device. However, the technician is
unable to log into the device with LDAP credentials but is able to do so with a local user account.
Which of the following is the MOST likely reason for the problem?
A. Username is misspelled is the device configuration file
B. IDS is blocking RADIUS
C. Shared secret key is mismatched
D. Group policy has not propagated to the device
Correct Answer: C
Explanation
AAA through RADIUS uses a Server Secret Key (a shared secret key). A secret key mismatch could
cause login problems.
Authentication, authorization, and accounting (AAA) allows anetwork to have a single repository of
user credentials. A network administrator can then, for example, supply the same credentials to log
in to various network devices (for example, routers and switches). RADIUS and TACACS+ are
protocols commonly used tocommunicate with an AAA server.
