CompTIA 220-1202 Exam Dumps

One of the most common causes for performance degradation on smartphones isstorage or memory overloaddue to excessive apps.Uninstalling unused appsis a basic but effective first diagnostic step.

FromTravis Everett -- All-in-One Exam Guide:

''Start troubleshooting sluggish smartphones by clearing unused apps and files before performing advanced diagnostics or resets.''

The correct answer is B. Task Manager, because Task Manager allows technicians to view, manage, and terminate running processes, including those that are frozen or unresponsive. If an application process is already running but not responding, launching it again will fail until the existing process is stopped.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, Task Manager is the primary Windows tool for troubleshooting application hangs, excessive resource usage, and nonresponsive programs. Technicians can end the task and relaunch the application cleanly.

The Travis Everett & Andrew Hutz -- All-in-One Exam Guide explains that Resource Monitor provides detailed performance metrics but is not optimized for quickly terminating frozen applications. Event Viewer logs errors but does not resolve active process issues.

The Mike Meyers / Mark Soper Lab Manual reinforces that Registry Editor should never be used for live application troubleshooting due to the risk of system instability.

Because the issue involves an unresponsive background process, Task Manager is the fastest and safest tool to resolve the problem, making B the correct answer.

The correct answer is C. Perform a clean installation. When ransomware has encrypted files and the organization does not pay the ransom, the priority is to remove all traces of malware and rebuild the system from a trusted state. Quentin Docter's Complete Study Guide explains that in ransomware situations, remediation may not be possible because user files are encrypted. It further states that in cases where no one can be certain what the malware payload has done, the proper remediation might be to sanitize the drive and reinstall the operating system from an image or manually reinstall it. A recovery partition or Windows Recovery Environment repair may leave infected files, settings, persistence mechanisms, or damaged user data behind. Upgrading to Windows 11 does not guarantee malware removal. A clean installation removes the existing compromised OS and provides the best path to full operation, followed by restoring clean data from known-good backups.

A ''utility failure'' means the building's AC power source has dropped out (blackout) or sagged severely, causing the workstation to lose power instantly and shut down. The best way to prevent an immediate shutdown during these events is an Uninterruptible Power Supply (UPS), which contains a battery and can continue supplying AC power long enough to keep the PC running briefly and allow a graceful shutdown. Mike Meyers' Lab Manual states that a UPS ''continues to supply AC power...during both brownouts and blackouts via a battery,'' preventing the computer from instantly losing power when the utility fails. Quentin Docter likewise explains that UPS devices protect against ''power sags and even power outages,'' using stored battery energy so the administrator (or OS integration) can safely shut down rather than crash off.

A surge suppressor protects from spikes, not outages. A redundant PSU only helps if the PSU fails, and Docter notes it cannot keep a system running during a power outage. A line voltage regulator helps stabilize voltage but doesn't provide power when utility power is absent.

The correct answer is C. Setting up image deployment for PXE, because PXE (Preboot Execution Environment) allows operating system installations and upgrades to be performed over the network without using removable storage. Since all removable media is disabled for security reasons, PXE-based deployment preserves existing security controls while enabling centralized OS upgrades.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, PXE is commonly used in enterprise environments to deploy or upgrade operating systems at scale. PXE works by booting client machines from a network interface and pulling installation images from a secured deployment server.

The Travis Everett & Andrew Hutz -- CompTIA A+ All-in-One Exam Guide explains that PXE is especially valuable when USB drives and external media are restricted. It ensures consistency, reduces human error, and maintains compliance with organizational security policies.

The Mike Meyers / Mark Soper Lab Manual reinforces that copying ISO files locally still requires write access and may violate security baselines. External drives are explicitly prohibited, and hardware tokens are authentication tools---not deployment mechanisms.

Because PXE enables secure, centralized, removable-media-free OS upgrades, it is the most appropriate solution, making C the correct answer.
