Which two details are captured from the subnet mask? (Choose two.)
The correct answer is A. portion of an IP address that refers to the subnet D. part of an IP address that refers to the host. A subnet mask is a 32-bit number that divides an IP address into two parts: (A) the network/subnet portion - the bits where the mask has 1s identify which part of the IP address refers to the network or subnet; and (D) the host portion - the bits where the mask has 0s identify…

Explanation
A subnet mask is a 32-bit number that divides an IP address into two parts: (A) the network/subnet portion - the bits where the mask has 1s identify which part of the IP address refers to the network or subnet; and (D) the host portion - the bits where the mask has 0s identify which part of the IP address refers to the specific host on that subnet. The subnet mask does not capture the default gateway (B) - that is a separate configuration. It does not provide a unique host ID (C) by itself; that comes from the host portion of the IP address combined with the mask. It does not indicate the physical network connection (E) - that is determined by the network interface.
