CompTIA A+ Core 2 (220-1202)Operational ProceduresMedium
A technician is troubleshooting a network connectivity issue for a remote user. The user reports that they are unable to access internal company resources but can browse external websites. The technician suspects a misconfigured VPN connection. Which of the following remote access technologies is MOST likely being used?
- ASSH (Secure Shell)
- BVPN (Virtual Private Network)
- CRDP (Remote Desktop Protocol)
- DVNC (Virtual Network Computing)
Show answer & explanationAnswer & explanation
Correct answer: B. VPN (Virtual Private Network)
A VPN creates a secure tunnel over a public network, allowing remote users to access internal company resources as if they were on the local network. The symptom of being able to access external sites but not internal ones strongly points to a VPN issue, as the VPN is what routes internal traffic.
Why the other options are wrong
- A. SSH is primarily used for secure command-line access or file transfers to specific servers, not for general internal network access.
- C. RDP is for remote desktop access to a specific machine, not for general network access to internal resources.
- D. VNC is similar to RDP, providing graphical remote access to a single machine, not network-wide internal resource access.
Virtual Private Network (VPN)
A secure, encrypted connection over a public network that allows remote users to access a private network and its resources.
- Creates a secure tunnel
- Allows access to internal network resources
- Encrypts data in transit
Memory trick: VPN is the key to the company's internal door.
