Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 854

Which QoS queuing method transmits packets out of the interface in the order the packets arrive?

Answer options

• A. custom
• B. weighted-fair
• C. FIFO
• D. priority

Correct answer: C

Explanation

The correct answer is C, FIFO (First In, First Out), which processes packets strictly in the order they arrive without prioritization. Options A, B, and D involve additional criteria for packet handling, such as customization, weighted distribution, or prioritization, which do not guarantee the order of arrival is preserved.
