What this SystemVerilog verification operator question tests

This is an easy SystemVerilog question that checks familiarity with a common data-structure operator used throughout testbench development. The operator provides FIFO-like behaviour—pushing data in during generation and popping it out during checking—and is essential vocabulary for anyone writing SystemVerilog verification code.

Understanding this operator and when to use it is foundational for building robust testbenches. Interviewers ask it to confirm you have hands-on experience with SystemVerilog's verification primitives, not just theoretical knowledge of the language syntax.
