CompTIA Security+ (SY0-601) — Question 583

Callers speaking a foreign language are using company phone numbers to make unsolicited phone calls to a partner organization. A security analyst validates through phone system logs that the calls are occurring and the numbers are not being spoofed. Which of the following is the most likely explanation?

Answer options

• A. The executive team is traveling internationally and trying to avoid roaming charges.
• B. The company’s SIP server security settings are weak.
• C. Disgruntled employees are making calls to the partner organization.
• D. The service provider has assigned multiple companies the same numbers.

Correct answer: B

Explanation

The correct answer is B because weak security settings on the company's SIP server can allow unauthorized calls to be made, which aligns with the scenario described. Option A does not relate to the unsolicited nature of the calls, C is less likely as it does not explain the language barrier, and D does not apply since the calls were validated as not being spoofed.
