200-901 Network Fundamentals Practice Question

Which THREE of the following are characteristics of HTTP/2 compared to HTTP/1.1?

⚠ Common exam trap

Cisco often tests the misconception that HTTP/2 is purely a performance upgrade without structural changes, leading candidates to incorrectly select plaintext headers or assume multiple TCP connections are still required.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Header compression using HPACK

HPACK compression reduces header overhead by encoding header fields, which is a key improvement over HTTP/1.1's uncompressed headers. This minimizes latency and bandwidth usage, especially for repeated headers like cookies and user-agent.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Header compression using HPACK
Why this is correct
HPACK reduces header overhead.
✓
Binary framing layer
Why this is correct
HTTP/2 uses binary, not text.
✗
Plaintext headers for debugging
Why it's wrong here
HTTP/2 uses compressed binary headers.
✗
Requires multiple TCP connections for parallel requests
Why it's wrong here
HTTP/1.1 often uses multiple connections; HTTP/2 uses one.
✓
Multiplexed streams over a single TCP connection
Why this is correct
Multiple streams can be sent concurrently.
