220-1201 Practice Question: A technician is setting up a new web server that…
A technician is setting up a new web server that must be accessible from the internet using HTTPS. The server is behind a firewall that performs port forwarding. After configuration, external users cannot reach the server, but internal users can. Which protocol and port combination must be forwarded to the server?
⚠ Common exam trap
Candidates often mistakenly choose UDP 443 due to confusion with QUIC or DNS, but the CompTIA A+ exam expects TCP 443 as the standard for HTTPS traffic.
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
✓
TCP 443
HTTPS uses TCP port 443 by default. Since the server must be accessible from the internet via HTTPS, the firewall must forward TCP port 443 to the server's internal IP address. Internal users can reach the server because they are on the same local network and bypass the firewall's port forwarding rule, but external traffic on port 443 is blocked unless the rule is correctly configured.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TCP 80
Why it's wrong here
Port 80 is used for HTTP, not HTTPS; forwarding only port 80 would not allow HTTPS access.
- ✗
UDP 443
Why it's wrong here
HTTPS uses TCP, not UDP; UDP 443 is not standard for web traffic.
- ✓
TCP 443
Why this is correct
HTTPS uses TCP port 443, so forwarding this port allows secure web access from the internet.
- ✗
TCP 3389
Why it's wrong here
Port 3389 is used for RDP (Remote Desktop Protocol), not web traffic.
