Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 300

By default, IP phones upgrade their images using the HTTP Service from the TFTP Server integrated into one or more of the call processing platforms. Which Port / Transport Protocol does this service use?

Answer options

• A. 6970 / UDP
• B. 443 / TCP
• C. 6970 / TCP
• D. 8080 / TCP

Correct answer: C

Explanation

The correct answer is C, as IP phones use TCP on port 6970 for image upgrades through the HTTP service. Options A and D are incorrect because they either use the wrong protocol or port. Option B is incorrect because it references HTTPS, which is not used for this specific service.
