B: Educating end users is important but occurs later in the incident response process.
C: Disabling System Restore is part of cleanup, not containment.
D: Updating and scanning should occur after the system is quarantined to prevent further infection or spread.

NEW QUESTION # 64
An organization is experiencing an increased number of issues. A technician notices applications that are not installed by default. Users are reporting an increased number of system prompts for software licensing. Which of the following would the security team most likely do to remediate the root cause?
- A. Implement stronger controls to block suspicious websites.
- B. Deploy an internal PKI to filter encrypted web traffic.
- C. Remove users from the local admin group.
- D. Enable stricter UAC settings on Windows.
Answer: C
Explanation:
When users have local administrative rights, they can install unauthorized applications - leading to licensing prompts, unsupported software, and potential security risks. By removing users from the local Administrators group, installations require elevated credentials, ensuring that only approved software is installed and reducing these recurring issues.
NEW QUESTION # 65
A user recently returned from an international trip and finds that their smartphone can connect to the Internet and send emails while at home on Wi-Fi, but cannot access any data services once they leave the house. Which of the following should the technician do FIRST to resolve this issue?
- A. Disconnect the VPN.
- B. Enable cellular data.
- C. Reinstall the SIM card.
- D. Increase data limits.
Answer: B
Explanation:
If the phone works on Wi-Fi but not off Wi-Fi, the most likely issue is that cellular data is disabled (or restricted). This aligns directly with the CompTIA A+ objective language for mobile troubleshooting, which explicitly includes "wireless/cellular data network (enable/disable)." After travel, users often enable airplane mode or disable cellular data to avoid roaming charges, and sometimes forget to re-enable it.
Quentin Docter's mobile connectivity discussion repeatedly distinguishes Wi-Fi access from cellular connectivity and treats cellular settings as a primary area to verify when Internet access is not available away from Wi-Fi. While data caps/limits could throttle service, they usually don't make all non-Wi-Fi browsing and email impossible immediately. VPN issues might block some access, but the simplest "most likely" resolution based on the symptom is re-enabling cellular data. Reinstalling the SIM is possible, but again not the first, most likely fix given the scenario framing. Therefore, Enable cellular data (A) is correct.
NEW QUESTION # 66
A technician must map a network drive on a piece of legacy equipment running an end-of-life OS.
Which of the following is the best script to map the drive using simple Windows commands?
- A. Java
- B. Shell
- C. Batch
- D. VB
Answer: C
Explanation:
A batch script is the best choice for mapping a network drive using simple Windows commands because it can execute command-line instructions like net use in legacy and modern Windows environments.
NEW QUESTION # 67
A user is renaming a .txt file to a .xml file. After renaming the file, Windows Explorer shows the filename as Document....xml. However, the document properties show the type of file as Text Document (.txt). Which of the following controls enables the user to correctly change the file type?
- A. Format command
- B. Personalization
- C. Hide extensions
- D. Indexing options
Answer: C
Explanation:
This issue happens when Windows is hiding known file extensions. If extensions are hidden, the user may only be changing the visible name (for example, changing "Document" to "Document.xml"), while the real filename remains something like Document.xml.txt. Windows Explorer then displays "Document.xml," but file properties still show the true type as Text Document (.txt) because the actual extension at the end is still .
txt, and Windows determines file type by that extension. The fix is to show file extensions by turning off the
"hide extensions" behavior-i.e., uncheck "Hide extensions for known file types" in File Explorer Options
/View settings. Quentin Docter specifically calls out that "Hide Extensions For Known File Types" is commonly changed because seeing extensions is "really handy," and shows steps to deselect "Hide File Extensions For Known File Types." The All-in-One guide and Mike Meyers' Lab Manual both reinforce that you toggle extensions by deselecting "Hide extensions for known file types." References: Quentin Docter - CompTIA A+ Complete Study Guide (File Explorer Options/View: hide extensions setting); Travis Everett & Andrew Hutz - CompTIA A+ All-in-One Exam Guide (Folder Options
/View: toggle file extensions); Mark Soper - Mike Meyers' A+ Lab Manual (show/hide extensions and how to change the setting).

- C. Install anti-malware software.
- D. Deploy MDM.
Answer: D
Explanation:

- whitelisting approved applications and blocking all others. By deploying MDM, the help desk can centrally control which apps users may install on company-owned phones, preventing unauthorized tools from being added in the future.
NEW QUESTION # 71
A technician is unable to upgrade a desktop computer from Windows 10 to Windows 11. Which of the following is most likely preventing the upgrade?
- A. Slow HDD spindle speed
- B. High RAM latency
- C. Missing TPM module
- D. Low refresh rate
Answer: C
Explanation:
A missing TPM (Trusted Platform Module) is a common requirement for Windows 11, and its absence is most likely preventing the upgrade.
NEW QUESTION # 72
After a technician upgrades the RAM on a user's workstation, the system shows a "No boot device found" message. Which of the following is most likely the cause?
- A. The SATA HDD power cable is disconnected
- B. The boot order needs to be changed
- C. The installation disk is not available
- D. The drive needs to be reformatted
Answer: A
Explanation:
The correct answer is B. The SATA HDD power cable is disconnected, because RAM upgrades require opening the case, which can easily result in accidentally loosening or disconnecting internal cables. If the system cannot detect the boot drive, it will display a "No boot device found" error.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, one of the first troubleshooting steps after hardware changes is to verify that all internal cables-especially SATA data and power cables- are securely connected. A disconnected drive will not be detected by the BIOS or UEFI firmware.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that boot order changes are less likely unless the technician explicitly modified BIOS settings. Similarly, reformatting a drive would not occur during a RAM upgrade.
The Mike Meyers / Mark Soper Lab Manual reinforces that physical connection issues are among the most common causes of boot failures following hardware maintenance. A disconnected power cable prevents the hard drive from spinning up, making it invisible to the system.
Because the issue appeared immediately after opening the case for a RAM upgrade, the most likely cause is a disconnected SATA power cable, making B the correct answer.
