- A
Screen Sharing in System Settings > Sharing.
Why wrong: Screen Sharing allows remote control of the Mac's desktop, but it does not provide file-level access as a network drive. It is not the correct tool for sharing files with a Windows machine.
- B
File Sharing in System Settings > Sharing, and ensure SMB is enabled.
File Sharing with SMB is the standard way to share folders with Windows clients. The user must also add the specific folder to the Shared Folders list and set appropriate permissions.
- C
Internet Sharing in System Settings > Sharing.
Why wrong: Internet Sharing allows the Mac to share its internet connection with other devices, not to share files. It is unrelated to the scenario.
- D
Remote Login in System Settings > Sharing.
Why wrong: Remote Login enables SSH access to the Mac, which is a command-line interface. While files could be transferred via SCP, it does not create a browsable network drive for a Windows user.
Quick Answer
The correct answer is to enable File Sharing in System Settings and ensure SMB is turned on. This works because macOS uses the Server Message Block (SMB) protocol for file sharing, which is the native file-sharing protocol built into Windows, allowing the two operating systems to communicate without any extra software. On the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of cross-platform networking and the specific role of SMB in a mixed macOS and Windows environment. A common trap is confusing File Sharing with Screen Sharing, which only provides remote desktop access, not folder access. Remember the memory tip: “SMB is for sharing files, not screens—if you want to map a drive, SMB must be alive.”
220-1102 macOS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of macos features and tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 user on a Mac running macOS Big Sur needs to share a folder on their local network with a Windows colleague. The user wants the folder to appear as a network drive on the Windows machine without installing additional software. Which macOS feature should they enable and configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
File Sharing in System Settings > Sharing, and ensure SMB is enabled.
File Sharing in System Settings uses SMB (Server Message Block) protocol, which is natively supported by Windows. By enabling File Sharing and adding the folder to the Shared Folders list, the Mac acts as an SMB server. The Windows user can then connect to it using the Mac's IP address or hostname. Screen Sharing is for remote desktop, not file sharing.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Screen Sharing in System Settings > Sharing.
Why it's wrong here
Screen Sharing allows remote control of the Mac's desktop, but it does not provide file-level access as a network drive. It is not the correct tool for sharing files with a Windows machine.
- ✓
File Sharing in System Settings > Sharing, and ensure SMB is enabled.
Why this is correct
File Sharing with SMB is the standard way to share folders with Windows clients. The user must also add the specific folder to the Shared Folders list and set appropriate permissions.

Static NAT maps one inside address to one outside address.

Why it's wrong here
Internet Sharing allows the Mac to share its internet connection with other devices, not to share files. It is unrelated to the scenario.
- ✗
Remote Login in System Settings > Sharing.
Why it's wrong here
Remote Login enables SSH access to the Mac, which is a command-line interface. While files could be transferred via SCP, it does not create a browsable network drive for a Windows user.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Remote Login enables SSH access to the Mac, which is a command-line interface. While files could be transferred via SCP, it does not create a browsable network drive for a Windows user.
Scenario analysis trap
Internet Sharing allows the Mac to share its internet connection with other devices, not to share files. It is unrelated to the scenario.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
