CompTIA Network+ (N10-006) — Question 18

A technician needs to install a server to authenticate remote users before they have access to corporate network resources when working from home.
Which of the following servers should the technician implement?

Answer options

• A. DNSSEC
• B. PPP
• C. RAS
• D. VLAN
• E. NAT

Correct answer: C

Explanation

The correct answer is C, RAS (Remote Access Service), which is specifically designed to provide remote users with secure access to network resources. The other options do not serve this purpose: A (DNSSEC) is for securing DNS data, B (PPP) is a protocol for direct connection, D (VLAN) is for network segmentation, and E (NAT) is for translating IP addresses.
