220-1102 Practice Question: A user is traveling and needs to access a file on…

A user is traveling and needs to access a file on their office computer. They have a dynamic IP address at the hotel. Which remote access technology should the technician recommend for a secure connection?

⚠ Common exam trap

CompTIA often tests the misconception that remote access requires a static IP or that direct RDP is acceptable, but the key is that a VPN handles dynamic IPs and provides encryption, which is essential for secure remote access over public networks.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Set up a Virtual Private Network (VPN) client on the user's laptop to connect to the office network.

A VPN client creates an encrypted tunnel between the user's laptop and the office network, allowing secure access to files regardless of the user's dynamic IP address. VPNs authenticate the user and encrypt all traffic, protecting data over untrusted networks like hotel Wi-Fi.

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Configure a direct RDP connection using the user's home IP address.

    Why it's wrong here

    Configuring a direct RDP connection using the user's home IP address is fundamentally flawed for accessing an office computer. To enable direct RDP from outside the network, the office computer's network would require a publicly routable IP address and specific port forwarding rules, exposing the internal machine directly to the internet. This practice is a significant security risk, making the office computer vulnerable to attacks, and is often impractical due to dynamic public IP addresses at the office location.

  • ✓

    Set up a Virtual Private Network (VPN) client on the user's laptop to connect to the office network.

    Why this is correct

    Setting up a Virtual Private Network (VPN) client on the user's laptop is the most secure and flexible solution for remote access. A VPN establishes an encrypted tunnel over any internet connection, allowing the user's laptop to securely become a virtual part of the office network, regardless of the user's current IP address. This provides encrypted access to all authorized internal network resources, such as shared drives, applications, and other services, as if the user were physically in the office.

  • ✗

    Use a remote desktop gateway that requires a static IP on the user's end.

    Why it's wrong here

    The statement that a Remote Desktop Gateway (RD Gateway) requires a static IP on the user's end is incorrect. An RD Gateway acts as a secure proxy, allowing remote users with dynamic IPs to connect to internal RDP resources without direct exposure of those resources to the internet. While the gateway server itself needs a static public IP and a valid certificate, the client connecting to it does not. However, RD Gateway primarily facilitates RDP access to specific machines, not general network access to shared folders or other services like a VPN.

  • ✗

    Email the file to the user as an attachment.

    Why it's wrong here

    Emailing a file to the user as an attachment is not a remote access solution and presents several significant drawbacks. This method lacks security, as email is not inherently encrypted, and it does not provide ongoing access to network resources or real-time collaboration. Furthermore, email attachments are subject to size limitations, can lead to version control issues, and do not address the broader need for a user to access an entire office network while traveling.
