Multiple Choice

Which of the following statements are valid Wireshark capture filters? (Choose TWO correct answers.)

The correct statement that represents a valid Wireshark capture filter is one that adheres to the syntax and rules set by Wireshark for capturing packets based on port numbers and protocols. The statement "tcp portrange 10000-15000" uses the appropriate format in Wireshark for filtering traffic. This syntax specifies that the filter is looking for TCP packets within a defined range of port numbers from 10000 to 15000. The keyword "tcp" indicates the protocol, and "portrange" is used correctly to specify a range of ports in this context. This precise formulation is essential for ensuring that the capture is limited to the desired traffic. In contrast, other choices may employ incorrect or unsupported syntax or conventions for defining capture filters within Wireshark. For example, using colons or a dash in a manner that does not conform to the specified syntax could result in an invalid filter. Therefore, the validity of a capture filter depends on its adherence to these rules, making the selected option a proper representation of how to filter by TCP port ranges in Wireshark.
