Question 1

In which firewall mode does Cisco Secure Firewall operate without IP addresses on its interfaces?

Answer 1

Transparent mode.

Question 2

What are the two firewall modes available in Cisco Secure Firewall?

Answer 2

Transparent and Routed modes.

Question 3

What advantage does routed mode have over transparent mode in Cisco Secure Firewall?

Answer 3

It supports advanced services like routing, DHCP, and VPN functionalities.

Question 4

Explain a practical scenario where transparent mode is preferable.

Answer 4

When firewall protection is required without changing the existing network addressing scheme.

Question 5

What is the primary functional difference between inline interfaces and inline tap interfaces?

Answer 5

Inline interfaces actively block malicious traffic, while inline tap interfaces only detect and monitor copied traffic without blocking.

Question 6

When would it be beneficial to deploy passive mode interfaces in your network? Provide an example scenario.

Answer 6

For intrusion detection purposes without affecting actual traffic flow, such as monitoring mirrored traffic for policy tuning or compliance verification.

Question 7

How does clustering differ from failover pair deployments in Cisco Secure Firewall? Provide one advantage.

Answer 7

Clustering groups multiple firewalls actively handling traffic simultaneously, increasing throughput and availability, whereas failover pairs have one active and one standby firewall. Advantage: Enhanced scalability alongside high availability.

Question 8

What scenario might justify using the fail-to-wire option with inline interfaces?

Answer 8

Ensuring business continuity by allowing traffic flow during firewall outages, power failures, or software upgrades.
