What are the two most common methods of placing a BIG-IP device into a network environment? (Choose two.)

The correct answer is D. SNAT configuration F. Routed configuration. The two most common BIG-IP network placement methods are SNAT configuration and Routed configuration, each providing a different mechanism to ensure return traffic flows back through the LTM.

Why each option

The two most common BIG-IP network placement methods are SNAT configuration and Routed configuration, each providing a different mechanism to ensure return traffic flows back through the LTM.

AChanneled configuration

Channeled configuration is not a recognized BIG-IP network placement methodology.

BVLAN configuration

VLAN configuration describes internal network segmentation on the BIG-IP and does not define a network deployment topology.

CNAT configuration

NAT configuration is a general networking concept and is not classified as one of the primary BIG-IP placement methods.

DSNAT configurationCorrect

SNAT (Source Network Address Translation) configuration causes the BIG-IP to replace the client source IP with one of its own self IP addresses, forcing servers to always send return traffic back through the BIG-IP regardless of network routing.

EAsymmetric configuration

Asymmetric configuration is not a standard BIG-IP deployment mode - it describes a routing condition where traffic takes different paths in each direction, which BIG-IP deployments are specifically designed to avoid.

FRouted configurationCorrect

Routed configuration places the BIG-IP inline as the default gateway for backend servers, so server response traffic naturally traverses the LTM without requiring source address translation.
