Cisco Updated 300-710 Exam Questions and Answers by cade

Traditionally, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets. A transparent firewall, on the other hand, is a Layer 2 firewall that acts like a “bump in the wire,” or a “stealth firewall,” and is not seen as a router hop to connected devices. However, like any other firewall, access control between interfaces is controlled, and all of the usual firewall checks are in place. Layer 2 connectivity is achieved by using a " bridge group " where you group together the inside and outside interfaces for a network, and the ASA uses bridging techniques to pass traffic between the interfaces. Each bridge group includes a Bridge Virtual Interface (BVI) to which you assign an IP address on the network. You can have multiple bridge groups for multiple networks. In transparent mode, these bridge groups cannot communicate with each other.https://www.cisco.com/c/en/us/td/docs/security/asa/asa97/configuration/general/asa-97-general-config/intro-fw.html

Interface → outside

Source Host → any

Packet 1 source → 209.165.201.2

Packet 2 source → 209.165.201.1

Packet 4 ICMP message → echo reply

Unused Options:

209.165.202.1

209.165.202.2

The capture must run on the FTDv outside interface, where the client’s translated address is 209.165.201.2. Selecting any as the source-host criterion captures both the outbound echo requests and the inbound ICMP responses. The first request therefore appears as 209.165.201.2 to 209.165.202.2. When the initial traceroute probe expires at R1, the router generates an ICMP time-exceeded response using its interface address 209.165.201.1. A later probe reaches Server1, which returns an ICMP echo reply from 209.165.202.2 to 209.165.201.2. The completed-answer exhibit in List B places several IP addresses inconsistently; the mapping above follows the displayed topology and actual ICMP traceroute packet flow.
