220-1102 Practice Question: Remotely access a Windows 10 computer that is…
This 220-1102 practice question tests your understanding of remotely access a windows 10 computer that is…. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician needs to remotely access a Windows 10 computer that is located on a different network subnet. The technician has administrative credentials. Which technology should be configured to allow this remote access without additional third-party software?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Remote Desktop with port forwarding on the router
Remote Desktop (RDP) with port 3389 forwarded allows full remote control across subnets. It is built into Windows Pro/Enterprise editions.
B
Distractor review
Remote Assistance
Remote Assistance requires an outbound invitation from the target computer, which is not suitable for always-on remote access.
C
Distractor review
Quick Assist
Quick Assist is a Windows 10/11 tool for screen sharing but typically used for one-time support and not designed for persistent remote access across subnets.
D
Distractor review
SSH
SSH is not installed by default on Windows and is primarily for command-line access, not full graphical remote desktop.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.

Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

FAQ
Questions learners often ask
What does this 220-1102 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Remote Desktop with port forwarding on the router — Remote Desktop Protocol (RDP) can be used for remote access over different subnets if port 3389 is forwarded on the router to the target computer. This allows the technician to connect from a remote location using the Remote Desktop client. Remote Assistance requires an invitation, Quick Assist is primarily for Windows 10/11 support sessions, and SSH is not a native Windows feature for remote desktop.
What should I do if I get this 220-1102 question wrong?
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 220-1102 subnetting questions on CIDR, address ranges, and subnet selection.
