FC0-U71 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. C:\Users\jsmith> netstat -ano Active Connections Proto Local Address Foreign Address State PID TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 1056 TCP 0.0.0.0:445 0.0.0.0:0 LISTENING 4 TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING 1200 TCP 192.168.1.100:49152 52.84.12.34:443 ESTABLISHED 3400 TCP 192.168.1.100:49153 10.0.0.5:80 TIME_WAIT 0
Refer to the exhibit. A technician sees an established connection to an external IP on port 443 from PID 3400. What is the most likely purpose of this connection?
⚠ Common exam trap
Many candidates confuse port 443 with other common services like SMB or RDP, or assume any encrypted connection is SSH (port 22), but the question specifically ties port 443 to HTTPS, which is the standard for secure web traffic.
Answer choices
Why each option matters

Correct answer & explanation
✓
Secure web browsing (HTTPS)
Port 443 is the default port for HTTPS (HTTP over TLS/SSL), which is used for secure web browsing. PID 3400 indicates a specific process, likely a web browser or an application making an encrypted HTTPS connection to an external IP. This matches the purpose of secure web browsing.
