- A
Install a third-party antivirus app.
Why wrong: Incorrect. Antivirus apps are not necessary for iOS encryption or remote wipe.
- B
Enable the device's passcode and Touch ID/Face ID.
Correct. A passcode is required to enable hardware encryption and to allow remote wipe via MDM.
- C
Disable iCloud backup for the device.
Why wrong: Incorrect. Disabling iCloud backup does not affect encryption or remote wipe capabilities.
- D
Set up a VPN connection for all traffic.
Why wrong: Incorrect. VPN encrypts data in transit, not the device itself, and does not enable remote wipe.
Question 523 of 1,020
iPhone Corporate Email Encryption and Remote Wipe
This 220-1201 practice question tests your understanding of mobile device application support. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is configuring a corporate iPhone for a new executive. The user needs to access company email, calendar, and contacts, but the company requires that all data be encrypted and the device be remotely wipeable. Which configuration step is essential?
Quick Answer
The answer is enabling the device’s passcode and Touch ID/Face ID, because this step is the prerequisite for both iPhone corporate email encryption and remote wipe. Without a passcode, iOS cannot enable hardware-based data encryption, and mobile device management (MDM) policies—including remote wipe—cannot be enforced. On the CompTIA A+ Core 1 220-1201 exam, this concept tests your understanding of iOS enterprise features and the chain of dependencies: passcode unlocks encryption, which then allows MDM to manage security. A common trap is choosing an MDM server configuration alone, but the exam emphasizes that encryption must be active first. Remember the memory tip: “No passcode, no protection—encryption and remote wipe both need that key.”
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
✓
Enable the device's passcode and Touch ID/Face ID.
Enabling the device's passcode and Touch ID/Face ID is essential because it activates hardware-backed encryption on iOS devices. Without a passcode, iOS cannot generate the encryption key required to protect data at rest, and remote wipe capabilities are contingent on the device being able to authenticate and enforce management commands. This step directly satisfies the corporate requirements for data encryption and remote wipeability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the misconception that encryption requires a third-party tool or that VPNs provide device-level encryption, when in fact iOS's built-in Data Protection is triggered solely by enabling a passcode.
Detailed technical explanation
How to think about this question
When a passcode is enabled, iOS uses the device's UID (a unique hardware key) combined with the user's passcode to derive a class key that encrypts the Data Protection class 'NSFileProtectionComplete'. This ensures that files are encrypted until the device is unlocked. Remote wipe is executed by the MDM server sending a command that triggers the device to overwrite the effaceable storage containing the encryption keys, making data irrecoverable without a passcode.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
