Which operator matches either of two conditions in a display filter?

• A. &&
• B. ||
• C. **
• D. ->

Answer: (B)

Using the OR behavior is how you express “either condition” in a display filter. The OR operator is written as two vertical bars: ||. It evaluates to true if at least one of the two conditions is true, so a filter like tcp || udp will match packets that are either TCP or UDP.

In contrast, the AND operator (&&) requires both conditions to be true at the same time, which isn’t what “either” means. The other symbols don’t represent a logical OR for combining conditions in display filters, so they don’t achieve the same behavior.
