220-1202 Exam Dumps - CompTIA A+ Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract:

Credential managers or password vaults (e.g., Windows Credential Manager, KeePass, or LastPass) store passwords securely. The integrity of such tools heavily depends on the strength of the master password protecting the vault. If compromised, all saved credentials could be exposed. Therefore, setting a secure master password is crucial.

A. Login time restrictions are general user account settings, not specific to credential managers.

C. TPM is used more commonly for full disk encryption, not specifically required for password managers.

D. The lock screen protects general access but does not protect stored credentials alone.

A VPN is the best choice because it is designed to provide secure remote access to an internal network over the Internet by creating an encrypted tunnel. Once the VPN is established, the remote user’s device effectively becomes part of the corporate network and can use the appropriate tools for each server type (for example, SSH to Linux and RDP to Windows) without exposing those management services directly to the public Internet. Quentin Docter explains that a VPN “extends your company’s internal network across the Internet,” creating a private connection through “encryption and encapsulation,” and that the host becomes part of the internal network (often receiving an internal IP). The All-in-One guide reinforces this by describing VPNs as an encrypted tunnel over the open Internet.

By comparison, RDP is “used exclusively with Microsoft operating systems,” so it doesn’t meet the Linux requirement. FTP is for file transfers, not full secure remote access, and RMM is primarily for centralized IT monitoring/management rather than a general user remote-access method.

The Local Users and Groups Manager (lusrmgr.msc) is the utility for managing user accounts, including renaming the default Administrator.

From Quentin Docter – Complete Study Guide :

“The lusrmgr.msc snap-in allows renaming and managing local user accounts, including the default administrator.” .

Device encryptionensures that even if someone bypasses biometrics or has physical access to the phone, they cannot read the stored data without the encryption key.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Encryption is the most effective way to protect data at rest. Even if the device is lost or stolen, encryption ensures the data remains inaccessible without the correct key or passcode.”

Adding ten high-end graphics/animation desktops can dramatically increase the electrical load on the room’s existing circuits. High-performance CPUs and GPUs draw substantially more wattage than typical office PCs, and that wattage translates into higher current (amperage) on the circuit. Mike Meyers’ Lab Manual explains the relationship V × A = W and warns that wiring and circuits have amperage ratings; pushing too much current can overheat wiring and trigger safety devices. It also explains that circuit breakers are rated for a specified amperage and will open (trip) when overloaded to prevent overheating and damage. Therefore, before deployment, the technician should calculate expected power draw per system and ensure the desktops are distributed across sufficient circuits (or that electrical upgrades are made) to avoid repeated breaker trips, overheating risks, and downtime. While temperature and humidity matter for environmental control, the question is specifically about introducing multiple power-hungry workstations, making circuit power consumption the most critical planning factor for safe, stable operation. This aligns with A+ operational/environmental concepts around proper power handling and avoiding overload conditions.

The first step in the IT change management process is to identify and propose the change. In this case, the technician notices a need (end-of-life network switches), so the appropriate action is to formally propose a change. This proposal would be documented and submitted for approval before any planning or implementation occurs.

According to the CompTIA A+ 220-1102 objectives under Operational Procedures (Domain 4.0), the change management process follows these typical steps:

Submit a change request (Propose the change)

Review and approval (Approve the change)

Planning and scheduling (Schedule the change)

Implementation

Documentation and review

Therefore, proposing the change is the correct first step in accordance with standard ITIL-based change management practices.

At large events such as music festivals, cellular towers may become congested due to the high volume of users attempting to connect simultaneously. This congestion causes slow or failed data connections, which explains the email application being unable to sync or connect. This is a common real-world mobile connectivity issue in crowded areas.

A. Lack of storage would prevent saving attachments, not prevent connection attempts.

B. Company firewalls usually don’t affect mobile access unless specific device restrictions are enforced.

D. Organizers do not have the ability to block the internet signal; only carriers manage mobile bandwidth.

The Linux machine likely formatted the drive in a file system like ext4, which Windows cannot natively read. Reformatting the drive toexFATallows cross-platform compatibility.

FromAll-in-One Exam Guide:

“When migrating data between OSes, using a file system like exFAT ensures compatibility. Windows cannot read Linux-native file systems such as ext4 without third-party tools.”

To allow Remote Desktop Protocol (RDP) access, the firewall must be configured to allow inbound connections on TCP port 3389. If the Windows Firewall blocks RDP, users will not be able to connect remotely even if the feature is enabled in system settings.

B. Computer Management allows configuration of services and local users, but not network access.

C. User Accounts is for account setup and control, but enabling remote access requires firewall configuration.

D. Ease of Access is unrelated to remote connectivity—it’s for accessibility features.

The correct answer is A. gpedit.msc , which opens the Local Group Policy Editor . Group Policy allows administrators to configure and enforce security-related settings, including screensaver timeout, password protection, and automatic locking , across systems or user accounts.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , Group Policy is commonly used to enforce security policies such as inactivity timeouts, especially in departments handling sensitive data like finance or HR.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that screensaver timeout settings can be configured under User Configuration → Administrative Templates → Control Panel → Personalization , ensuring systems lock automatically after a defined period of inactivity.

The Mike Meyers / Mark Soper Lab Manual reinforces that tools like certmgr.msc manage certificates, devmgmt.msc manages hardware devices, and perfmon.msc monitors system performance. None of these tools control user security policies.

Because the requirement is to enforce a shorter screensaver timeout for security , Group Policy Editor is the correct and professional tool, making A the correct answer.
