CrowdStrike Certified Falcon Administrator (CCFA) — Question 99

Which port and protocol does the sensor use to communicate with the CrowdStrike Cloud?

Answer options

• A. TCP port 22 (SSH)
• B. TCP port 443 (HTTPS)
• C. TCP port 80 (HTTP)
• D. TCP UDP port 53 (DNS)

Correct answer: B

Explanation

The correct answer is B, as the sensor communicates with the CrowdStrike Cloud over TCP port 443 using HTTPS, which is a secure protocol. The other options are incorrect because port 22 is for SSH, port 80 is for unencrypted HTTP traffic, and port 53 is used for DNS queries, none of which are used for this specific communication.
