CompTIA Cloud+ (CV0-004) — Question 112

A social networking company operates globally. Some users from Brazil and Argentina are reporting the following error: website address was not found. Which of the following is the most likely cause of this issue?

Answer options

• A. Client DNS misconfiguration
• B. Regional DNS provider outage
• C. DNS server misconfiguration
• D. DNSSEC key mismatch

Correct answer: B

Explanation

The correct answer is B, as a regional DNS provider outage would affect users in a specific geographic area, leading to the reported error. Options A and C refer to misconfigurations that would generally affect all users, while D relates to DNSSEC issues that are less likely to cause the 'website address not found' error for a localized group.
