QUESTION 21:
At which location in an access control list is it recommended that you place the
more specific entries?
A. in the middle of the access control list?
B. higher in the access control list
C. lower in the access control list
D. at the bottom of the access control list
Answer: B
Explanation:
Place more specific access list statements higher in the access list. Ensure statements at
the top of the access list do not negate any statements found lower in the list.
For example; blocking all UDP traffic at the top of the list negates the blocking of SNMP
packets lower in the list.
Care must be taken that statements at the top of the access list do not negate any
statements found lower in the list.
QUESTION 22:
How does HIPS inspect for attacks?
A. by intercepting traffic that is incoming to the network interface card
B. by inspecting syslog messages
C. by inspecting traffic that is outgoing from the network interface card
D. by intercepting calls to the OS kernel
E. by inspecting API message between applications
Answer: D
Explanation:
HIPS operates by detecting attacks occurring on a host on which it is installed.

HIPS works by intercepting operating system and application calls, securing the
operating system and application configurations, validating incoming service requests,
and analyzing local log files for after-the-fact suspicious activity.
QUESTION 23:
Which component within the Cisco Network Admission Control architecture acts as
the policy server for evaluating the endpoint security information that is relayed
from network devices, and for determining the appropriate access policy to apply?
A. CiscoWorks
B. CiscoWorks VMS
C. Cisco Secure ACS
D. Cisco Trust Agent
E. Cisco Security Agent
