The true statement is a downloadable ACLs are downloaded from the PIX Firewall to the Cisco Secure ACS server during authentication Answer: C Explanation: There are two methods of configuring downloadable ACLs on the AAA server. The first method, downloading named ACL Reference: Cisco Secure PIX Firewall Advanced 3.1 12-40

QUESTION 12 Jason the security administrator at Cisco Highway Inc.is working on configuring the PIX Firewall command. Why is the group tag in the aaa-server command important?

A. It is important because the group tag identifies which users require authorization to use certain services.

B. It is important because the group tag identifies which user groups must authenticate.

C. It is important because the aaa command references the group tag to know where to direct authentication, authorization, or accounting traffic.

D. It is important because the group tag enables or disables user authentication services. Answer: C Explanation: Use the aaa-server command to specify AAA server groups...The AAA command references the group tag to direct authentication, authorization, and accounting traffic to the appropriate AAA server.

QUESTION 13 You work as network administrator at Cisco Highway. Cisco Highway's primary PIX Firewall is currently the active unit in your failover topology. What will happen to the current IP addresses on the primary PIX Firewall if it fails?

A. The current IP addresses on the primary PIX Firewall remain the same, but the current IP addresses of the secondary become the virtual IP addresses you configured.

B. The current IP addresses will be deleted.

C. The ones on both the primary and secondary PIX Firewalls are deleted and both assume the failover IP addresses you configured.

D. The current IP addresses will become those of the standby PIX Firewall. Answer: D Explanation The failover feature allows you to use a standby PIX Firewall to take over the functionality of a failed PIX Firewall. When the active unit fails, it changes to the standby state, while the standby unit changes to the active state. The unit that becomes active takes over the active unit's IP addresses and MAC addresses, and begins passing traffic. The unit that is now in standby state takes over the standby IP addresses and MAC addresses.

QUESTION 14 The security team at Cisco Highway Inc.is looking for the truth about the PIX firewall. Which statement about the PIX Firewall is true?

A. The true statement is the PIX Firewall passes RIP updates between interfaces.

B. The true statement is the PIX Firewall uses the dynamically learned routes to forward traffic to the appropriate destinations but does not propagate learned routes to other devices.

C. The true statement is you cannot configure the PIX Firewall to learn routes dynamically from RIP version 1 or RIP version 2 broadcasts.

D. The true statement is the PIX Firewall uses dynamically learned routes to forward traffic to the appropriate destinations, passes RIP updates between its interfaces, and propagates learned routes to other devices. Answer: B Explanation: You can configure the PIX Firewall to learn routes dynamically from RIP version 1 or RIP version 2 broadcasts. Although the PIX firewall uses the dynamically learned routes itself to forward traffic to the appropriate destinations, it does not propagate learned routes to other devices. The Pix firewall cannot pass RIP updates between interfaces. It can, however, advertise one of its interfaces as a default route. Reference: Cisco Secure PIX Firewall Advanced 3.1 9-5

QUESTION 15 John the security administrator at Cisco Highway Inc.is working on configuring the PIX Firewall. John must choose two features on the PIX Firewall? (Choose two)

A. One feature is it uses Cisco Finesse operating system.

B. One feature is it uses Cisco IOS operating system.

C. One feature is it's based on Windows NT technology.

D. One feature is it analyzes every packet at the application layer of the OSI model.

E. One feature is it can be configured to provide full routing functionality.

F. One feature is it uses a cut-through proxy to provide user-based authentication connections. Answer: A, F Explanation: The PIX Firewall features the following technologies and benefits Non-Unix, secure, real-time, embedded system ASA Cut-through proxy - A user-based authentication method of both inbound and outbound connections, providing improved performance in comparison to that of a proxy server. Stateful packet filtering Finesse, a Cisco proprietary operating system, is a non-UNIX, non-windows NT, IOS- like operating system. Use of Finesse eliminates the risks associated with general-purpose operating system. Reference: Cisco Secure PIX Firewall Advanced 3.1 chap 3 pages 8-9

QUESTION 16 John the security administrator at Cisco Highway Inc.want to know what the default port number that the PIX Firewall uses to contact the AUS.

A. The default port number is 444

B. The default port number is 443 C. The default port number is 110

D. The default port number is 25 Answer: B Explanation: AUS uses port 443 SSL Reference: Page 18-12 of the course manual version 3.1

QUESTION 17 The security team at Cisco Highway Inc.is working on VoIP for the PIX Firewall. Which statements about the PIX Firewall in VoIP environments are true? (Choose two)

A. The true statement is the PIX Firewall allows SCCP signaling and media packets to traverse the PIX Firewall and interoperate with H.323 terminals.

B. The true statement is the PIX Firewall does not support the popular call setup protocol SIP because TCP can be used for call setup.

C. The true statement is the PIX Firewall supports the Skinny Client Control Protocol, which allows you to place IP phones and Call Manager on separate sides of the PIX Firewall.

D. The true statement is users behind the PIX Firewall can place outbound calls with IP phones because they use HTTP tunneling to route packets through port 80, making them appear as web traffic. Answer: A, C Explanation: Fix up protocol skinny port [-port] Enables the SCCP (skinny) protocol Dynamically opens pinholes for media sessions and nat -embedded IP addresses Supports Ip telephony Can coexist in an H323 environment Default port is 2000 Due to SCCP support, an IP phone and Cisco Call manager can now be placed on separate sides of the PIX Firewall.

F. The true statement is after you create a tunnel policy in the VPN tab's tunnel policy window, you must bind it to an interface from the Access Rules tab. Answer: B, E Explanation:

D: PDM hides the concept of the crypto map. IT does not support crypto maps that are not applied to any interface.

F: Open PDM -VPN tab --IPSec category ---tunnel policy ----select "Add" tunnel policy As you can see the interfaces is chosen in the Tunnel Policy window...not from the Access Rules tab (Not E)...the access rules tab is all about access lists and the PDM creates needed access list for VPN connections on its own...Again
