How is a CLI view different from a privilege level?
- A.
A CLI view supports only commands configured for that specific view whereas a privilege level supports commands available to that level and all the lower levels.
- B.
A CLI view can function without a AAA configuration whereas a privilege level requires AAA to be configured.
- C.
A CLI view supports only monitoring commands whereas a privilege level allows a user to make changes to an IOS configuration.
- D.
A CLI view and a privilege level perform the same function. However a CLI view is used on a Catalyst switch whereas a privilege level is used on an IOS router.
Correct Answer
A. A CLI view supports only commands configured for that specific view whereas a privilege level supports commands available to that level and all the lower levels.Explanation
A CLI view is different from a privilege level because it only supports the commands that are specifically configured for that view. On the other hand, a privilege level supports not only the commands available at that level but also all the commands available at lower levels. This means that a user with a higher privilege level can access and execute a wider range of commands compared to a user with a specific CLI view.Rate this question:

C. RADIUS uses UDP for transport and TACACS+ uses TCP.Explanation
Answer B is backwards. It’s TACACS+ that encrypts the whole communication, whereas RADIUS encrypts only the password. Answer D is incorrect but for a tricky reason. Although RADIUS is open source, TACACS+ isn’t quite a proprietary standard because Cisco has published it as an RFC (Request for Comment), part of the IETF standards track. Answer E is incorrect because RADIUS can use either ports 1645 and 1646 or ports 1812 and 1813 for authentication/authorization and accounting, respectively.Rate this question:

Which of the following are not included in the three main task areas in setting up for external AAA? (Choose all that apply.)
- A.
Configure the AAA network.
- B.
Install AAA supplicant software on IP hosts that will authenticate to the IOS router.
- C.
Identify traffic to which AAA is applied.
- D.
Set up users.
- E.
Install Cisco Secure ACS Solution Engine module on the Cisco IOS router.
Correct Answer(s)
B. Install AAA supplicant software on IP hosts that will authenticate to the IOS router.
E. Install Cisco Secure ACS Solution Engine module on the Cisco IOS router.Explanation
Answer B is correct because you do not need special software on an IP host in order to enable AAA for the network. Answer E is correct because the Cisco Secure ACS Solution Engine is an appliance that comprises a selfcontained AAA server solution. It is not an add-on module for a router, and the router is the AAA client in this scenario anyway.Rate this question:

Select the one answer with the correct two terms to fill in the following blanks. There are two distinct types of AAA authorization policies: .________ policies that define access rules to the router. .________ policies that define access rules through the router.
- A.
Network, Exec
- B.
Packet, Character
- C.
Character, Packet
- D.
Exec, Network
- E.
Administrative, User
Correct Answer
D. Exec, NetworkExplanation
The use of the terms “packet” and “character” are deliberately misleading because these refer to types of access in general (see Figure 3.10), but not specific types of AAA authorization policies. Answer E is simply wrong but sounds like it might be right to someone who hasn’t read the Exam Cram.Rate this question:

True or false. A general management guideline is to ensure that clocks on network devices are not synchronized with an external time source because this is a known vulnerability.
- A.
TRUE
- B.
FALSE
Correct Answer
