An organization wants to manage accounts and access policies consistently across many network devices. Which approach best fits that goal?
- A
Centralized AAA
- B
A separate local database on each device
- C
Accounting without authentication
- D
A named method list that bypasses the AAA server
A Cisco IOS-style login method list tries TACACS+ and then local authentication. The TACACS+ server responds and denies a user's login. What should you expect?
- A
The device always tries the local account after any TACACS+ result.
- B
The device tries the local account because a denial means the server did not respond.
- C
The device does not bypass the server's denial by trying the local account.
- D
The device grants access because the server has responded.
A small network needs access control that can continue working without an external AAA server. Which is a suitable advantage of using each device's local database?
- A
It centrally synchronizes policies across all devices.
- B
It can work independently of an AAA server and suit a small number of devices.
- C
It requires a reachable TACACS+ server for each login.
- D
It automatically centralizes accounting records from every device.
Select all accurate descriptions of the three AAA functions.
- A
Authentication verifies a user's identity.
- B
Authorization determines which commands or resources an authenticated user may use.
- C
Accounting records activity such as session times or commands used.
- D
Authentication by itself determines every command the user may run.
Select all statements accurately describing TACACS+ or RADIUS.
- A
TACACS+ is commonly used for network-device administration.
- B
RADIUS is described as separating authentication, authorization, and accounting, while TACACS+ combines them.
- C
TACACS+ separates its authentication, authorization, and accounting functions.
- D
RADIUS cannot return service or configuration information.
Recording session activity can support auditing and troubleshooting, but the recording itself does not grant the user access.
- A
True
- B
False
A named AAA method list can be applied to a specific line or service.
- A
True
- B
False
In centralized AAA, what is the term for the network device that sends requests to the shared server?
Which protocol is commonly used for centralized network-device administration and separates authentication, authorization, and accounting?
In the command aaa accounting exec default start-stop group tacacs+, how many distinct session boundaries are recorded by start-stop? Enter the count as an integer.
In the illustrative Cisco IOS-style setup, the authorization request covers the user's session, and the accounting method records activity.
RADIUS can return service and information.
You are preparing to enable AAA on a production device. Explain why you should keep an active management session open while testing a second login, and describe one additional safeguard to use before deployment.
On Cisco IOS-style devices, what single-word method-list name applies by default to the relevant service?
An administrator has successfully logged in. Which AAA function determines whether that administrator may change a switch's configuration?
- A
Checking whether the submitted credentials match an identity
- B
Deciding which commands an authenticated user may use
- C
Recording the user's session start and stop times
- D
Creating a shared user database across devices
A small site has only a few network devices and needs access control to keep working if its AAA server is unreachable. Which approach best fits this need?
- A
Use centralized AAA because each device must contact a shared server to authenticate locally
- B
Use local access control because each device can check its own user database without an AAA server
- C
Use accounting because it creates accounts on devices automatically
- D
Use a named method list because it stores user credentials centrally
An organization wants to manage accounts and access policies consistently across many network devices. Which approach best meets that goal?
- A
Centralized AAA, because it supports shared identity and policy management across many devices
- B
Local access control, because it automatically synchronizes accounts across all devices
- C
Accounting, because it determines which commands each user may run
- D
A named method list, because it removes the need for device-server communication
An administrator creates a method list named ops rather than using default. Which statement describes how a named method list can be used?
- A
It always overrides every other method list on the device
- B
It is used only to record session start and stop times
- C
It can be applied to a specific line or service
- D
It automatically provides local authentication if a server denies access
On Cisco IOS-style method lists, if the TACACS+ server responds and denies access, the device then tries the local account.
- A
True
- B
False
