1. Topic 1, New Set Questions
Which protocol authenticates connected devices before allowing them to access the LAN?
A. 802.1d
B. 802.11
C. 802.1w
D. 802.1x
Answer: D
Explanation:
802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server.
The supplicant is a client device (such as a laptop) that wishes to attach to the LAN/WLAN. The term
‘supplicant’ is also used interchangeably to refer to the software running on the client that provides
credentials to the authenticator. The authenticator is a network device, such as an Ethernet switch or
wireless access point; and the authentication server is typically a host running software supporting the
RADIUS and EAP protocols.
The authenticator acts like a security guard to a protected network. The supplicant (i.e., client device) is
not allowed access through the authenticator to the protected side of the network until the supplicant’s
identity has been validated and authorized. An analogy to this is providing a valid visa at the airport’s
arrival immigration before being allowed to enter the country. With 802.1X port-based authentication, the
supplicant provides credentials, such as user name/password or digital certificate, to the authenticator,
and the authenticator forwards the credentials to the authentication server for verification. If the
authentication server determines the credentials are valid, the supplicant (client device) is allowed to
access resources located on the protected side of the network.

2.What is a difference between TACACS+ and RADIUS in AAA?
A. Only TACACS+ allows for separate authentication.
B. Only RADIUS encrypts the entire access-request packet.
C. Only RADIUS uses TCP.
D. Only TACACS+ couples authentication and authorization.
Answer: A
Explanation:
Authentication and Authorization
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS
server to the client contain authorization information. This makes it difficult to decouple authentication and
authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions
that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible
to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates
on a Kerberos server, it requests authorization information from a TACACS+ server without having to
re-authenticate. The NAS informs the TACACS+ server that it has successfully authenticated on a
Kerberos server, and the server then provides authorization information.
During a session, if additional authorization checking is needed, the access server checks with a
TACACS+ server to determine if the user is granted permission to use a particular command. This
provides greater control over the commands that can be executed on the access server while decoupling
from the authentication mechanism.

3.Which statement about the IP SLAs ICMP Echo operation is true?
A. The frequency of the operation .s specified in milliseconds.
B. It is used to identify the best source interface from which to send traffic.
C. It is configured in enable mode.
D. It is used to determine the frequency of ICMP packets.
Answer: D
