Free Practice Questions for CompTIA 220-1201 Exam

Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.

Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.

Why Not C (VPN): VPN secures communication but does not enforce device controls.

Why Not D (SSL): SSL secures data in transit but does not provide device management.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, device management concepts​.

A. Run the maintenance application:

Most modern printers include a built-in maintenance application that can calibrate the print heads and correct alignment issues. Running this tool is the first step to address misalignment.

Incorrect Options:

B. Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not alignment problems.

C. Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is not the first step for fixing alignment.

D. Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.

Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly installed printer.

Comprehensive and Detailed Step-by-Step Explanation:

To answer this question, we need to identify the port numbers associated with email protocols used in client-server communication.

Port 25 (SMTP - Simple Mail Transfer Protocol):

This port is primarily used for sending emails between mail servers and from mail clients to mail servers (sending outbound mail).

SMTP is an essential protocol for email traffic.

An eSIM (embedded SIM) allows users to change carriers and provision new cellular service without installing any physical hardware. It is managed via software and is ideal for international travelers who need to switch providers quickly.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Install and configure mobile device network connectivity:

"eSIMs provide carrier flexibility by enabling remote provisioning and profile switching, making it possible to connect to different networks without a physical SIM card."

The scan-to-SMB feature allows the printer to send scanned documents to a shared folder (SMB share) on the network. Setting up a network share enables the device to securely and conveniently save files for user access.

A RAID 1 array uses disk mirroring, meaning all data is written identically to two drives. When one drive fails, the other contains a complete, current copy of the data. CompTIA A+ emphasizes that RAID 1 is designed for fault tolerance, allowing continued operation even after a disk failure.

The correct action is to replace the defective drive and allow the RAID controller to rebuild (sync) the mirror onto the new disk. This restores redundancy and ensures ongoing data protection. The system can typically continue running during the rebuild process.

Option A is incorrect because attempting to repair a failed drive is unreliable and unnecessary—RAID 1 already provides a healthy copy. Option B ignores the importance of restoring redundancy, leaving the system vulnerable to data loss if the remaining drive fails. Option D (restore from backup) is unnecessary because RAID 1 already preserves the data.

Therefore, the best solution is to install a new drive and resynchronize the array, preserving all data with minimal disruption.

Adegraded RAID 1array usually meansone of the drives has failed or is failing. The correctnext step is torun diagnostics on each driveto identify the faulty one. RAID 1 uses mirroring, so one good drive should still contain all the data.

Option B:chkdsk checks file system integrity, not hardware drive health.

Option C:Rebuilding should only occurafteridentifying and replacing a faulty drive.

Option D:RAID 0 offers no redundancy and would destroy data in this context.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.5: Given a scenario, troubleshoot problems related to storage devices.

The 12VHPWR connector can supply up to 600 watts of power, designed for high-end graphics cards.

Why Not A (400W): This is less than the connector’s maximum capability.

Why Not B (MOW): This is an invalid option.

Why Not D (700W): The maximum supported power is 600W.

RAID 0 (striping) provides the fastest read (and write) speeds at the lowest cost, as all disk capacity is used for storage and performance. However, it offers no redundancy.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – RAID types:

"RAID 0 stripes data across multiple disks, offering the best performance and lowest cost but no fault tolerance."

Comprehensive and Detailed Explanation

CompTIA A+ VoIP and network performance topics stress the importance of Quality of Service (QoS) and traffic separation.

Creating a separate VLAN for VoIP:

Reduces congestion

Prioritizes voice traffic

Prevents voice packets from competing with data traffic

Improves latency, jitter, and packet loss issues during peak hours

This directly fixes intermittent VoIP quality issues.

Why the other options are incorrect

B. Route calls through a gigabit port – Internal port speed is not the bottleneck; congestion is.

C. Shielded cable – Does not solve bandwidth or QoS issues.

D. Increase bit rate – Makes the problem worse, requiring more bandwidth.
