Why each option

To capture real packets associated with a specific Security Group Tag (SGT) on a Cisco Firepower device, the correct command syntax involves specifying "type inline-tag" followed by the SGT value. This command allows the engineer to filter and capture traffic directly related to SGT 64 for troubleshooting connectivity issues.

Acapture CAP type inline-tag 64 match ip any anyCorrect

The command `capture CAP type inline-tag 64 match ip any any` correctly specifies an inline-tag capture, which is used to filter and capture packets based on their Security Group Tag (SGT). The `type inline-tag` keyword indicates that the following number, `64`, is the SGT to match, allowing the engineer to isolate and analyze traffic associated with that specific SGT.

Bcapture CAP match 64 type inline-tag ip any any

The syntax `capture CAP match 64 type inline-tag ip any any` is incorrect because `type inline-tag` must precede the SGT value.

Ccapture CAP headers-only type inline-tag 64 match ip any any

While `headers-only` is a valid option for packet capture, the primary issue is the SGT matching syntax, which is correctly formed in option A, and this option adds an unnecessary restriction.

Dcapture CAP buffer 64 match ip any any

The syntax `capture CAP buffer 64 match ip any any` is incorrect; `buffer` is a keyword to specify buffer size, not for matching an SGT, and it's misplaced in the command for SGT filtering.
