220-1102 Question 207
Single answerRapid Security Response (RSR)A user with a company-issued iPhone reports that after installing an iOS Rapid Security Response (RSR), an internal web application began crashing in Safari. The security team wants to keep protections in place whenever possible, but the user needs temporary access to the app while the issue is investigated. Which action should the technician take FIRST?
- A
Remove the Rapid Security Response update from the iPhone and test the app again
- B
Perform a full factory reset of the iPhone and restore the user data from backup
- C
Disable all automatic updates so the iPhone will not receive future security fixes
- D
Downgrade the iPhone to the previous major iOS version using recovery mode
Show answer and explanation
Correct answer: A
Explanation
Rapid Security Response (RSR) is Apple's mechanism for delivering important security fixes more quickly than a full OS release on supported versions of iOS, iPadOS, and macOS. In a real support scenario, if a problem starts immediately after an RSR, the best first action is to remove that specific response if the platform allows it, then retest. This follows a standard troubleshooting principle: reverse the most recent, least invasive change first. Apple documentation describes RSR as a separate security delivery method and notes that responses can be removed in supported situations, unlike a normal full system update. For A+ Core 2 purposes, candidates should recognize that RSR is intended for rapid security patching and that targeted rollback of the response, when available, is preferable to factory resets, major OS downgrades, or disabling future updates.
- A. Correct.
Correct. Apple allows Rapid Security Responses to be removed separately from the main OS update in supported cases, which makes this the least disruptive first troubleshooting step when a problem appears immediately after an RSR. It lets the technician confirm whether the issue is tied to the security response while avoiding unnecessary data loss or a full OS rollback.
- B. Incorrect.
Incorrect. A factory reset is far more disruptive than necessary and is not an appropriate first step for an issue that began right after a specific security update. Resetting and restoring also does not specifically test whether the RSR caused the Safari compatibility problem.
- C. Incorrect.
Incorrect. Disabling automatic updates reduces the device's security posture and does not address the current compatibility issue in a targeted way. It may also cause the device to miss future critical patches. The goal is temporary troubleshooting with minimal security impact, not broad suppression of updates.
- D. Incorrect.
Incorrect. Downgrading to a previous major iOS version is not the normal first response to an RSR-related application issue and is often limited or unsupported depending on signing status. It is much more invasive than removing the specific Rapid Security Response.
