Which extended ACL entry command option matches all ports greater than the specified number?

To match all ports greater than a specified number in an extended ACL (Access Control List), the command option used is the greater than (gt) operator. This command is pivotal in scenarios where you need to filter traffic based on port numbers, specifically allowing or denying traffic that uses ports exceeding a particular value.

The "gt" operator allows the configuration of rules that can be very useful in managing network traffic more granularly. For example, if a network administrator wants to allow all traffic above a certain port number for specific applications or services, utilizing this command will achieve that goal effectively.

The other options serve different functions. The equal (eq) operator would only match a specific port number, the less than (lt) operator would match all ports less than the specified number, and the not equal (neq) operator would match all ports except the specified one. Thus, the usage of "gt" is essential for targeting a range of ports above a given threshold, making it the correct choice for this question.
