PIX Certification Questions
The Cisco Secure PIX Firewall Advanced exam
(CSPFA 642-521) is one of the exams associated
with the Cisco Certified Security Professional and
the Cisco Firewall Specialist certifications.
Candidates can prepare for this exam by taking
the CSPFA v3.2 course. This exam includes
simulations and tests a candidate's knowledge and
ability to describe, configure, verify and manage
the PIX Firewall product family. CCNA or CCDA
recertification candidates who pass the 642-521
CSPFA exam will be considered recertified at the
CCNA or CCDA level.

A network team has been tasked to develop a Cisco Secure
ACS solution for port-based authentication. The network
operation center for all three regions is located at Region 1.
What is the best solution to ensure availability to a Cisco
Secure ACS for port-based authentication?
Install a centralized primary and secondary authentication
server at Region 1, which Region 2 and 3 will use for
authentication.
Install a primary authentication server at each region and
use one of the authentication servers from another region
for redundancy.
Install a primary authentication server at Region 1 for
Region 2 and 3 to authenticate, and install a secondary
authentication server at Region 2 and 3 for redundancy.
Install a primary authentication server at each region and a
secondary authentication server at Region 1 for the network
operation center clients only.

The dot1x port-control auto interface configuration
command has been configured on the Catalyst 2950 shown
in the graphic. What is the effect of this command when the
link between the switch and the end user becomes active?

The configuration of VLANs on the switch minimizes the
exploit by containing the flood of traffic to the VLAN
supporting the attacker.
The impact of the CAM table overflow attack can be
lessened with the implementation of macof.
