220-1201 Exam Dumps - CompTIA A+ Questions and Answers

The symptoms clearly point to a hardware-level signal degradation issue, which is most commonly caused by a malfunctioning or damaged Wi-Fi antenna in the smartphone. CompTIA A+ mobile device troubleshooting emphasizes comparing the affected device ' s signal strength with other nearby devices. In this case, other devices in the same location have stronger Wi-Fi signals, meaning the network itself is functioning normally. The consistent low signal across multiple networks strongly suggests antenna failure.

Modern smartphones use internal antenna assemblies located along the frame or behind the back cover. If the antenna becomes loose, damaged, or obstructed, the device may show weak or unstable Wi-Fi connectivity, especially in crowded environments where strong, stable reception is required to maintain a connection.

Option B (outdated Wi-Fi standard) would limit speed but not cause significant signal weakness compared to surrounding devices. Option C (interference) affects all devices in an area similarly—not just one device. Option D (power settings) may reduce background activity or scanning frequency, but it does not cause consistently low signal strength.

Therefore, the most likely cause is a malfunctioning Wi-Fi antenna inside the smartphone.

D. Crimper:

A crimper is used to terminate an RJ45 cable properly by attaching the connector to the twisted-pair wires.

If the termination is not done correctly, the connection will be intermittent or fail entirely.

Incorrect Options:

A. Toner probe: Used to locate cables or trace their path, not for terminating RJ45 connectors.

B. Cable tester: Useful for testing connectivity but does not fix termination issues.

C. Punchdown: Used to connect wires to a patch panel or keystone jack, not for RJ45 connectors.

Key Takeaway: A crimper is the proper tool for fixing an improperly terminated RJ45 connection.

Comprehensive and Detailed Explanation From Exact Extract:

PIN printing (also known as secure printing) ensures that documents are held in a queue until the authorized user enters a PIN directly at the printer. This prevents unauthorized viewing of confidential documents.

Answer of both steps below.

A group of wires with different colors AI-generated content may be incorrect.

A screenshot of a computer AI-generated content may be incorrect.

Cloud storage platforms—such as OneDrive, Google Drive, and Dropbox—use synchronization to ensure that files updated on one device automatically update on all connected devices. CompTIA A+ defines synchronization as a key cloud characteristic that keeps local folders and cloud-stored versions consistent, enabling seamless multi-device collaboration.

Synchronization allows users to:

Modify files offline and have them sync once online

Access identical data on laptops, desktops, and mobile devices

Ensure real-time updates across multiple users or clients

Maintain version consistency and conflict resolution

A network share (A) is local to an organization and does not automatically sync across devices. Availability (C) relates to uptime and reliability, not file updates. Metered utilization (D) refers to cloud billing models where usage is tracked, not data syncing.

Thus, synchronization is the capability that ensures local folders update dynamically whenever changes occur.

TPM 2.0 (Trusted Platform Module) is often disabled by default in the UEFI BIOS. Enabling it is necessary to meet the requirements for certain Windows installations, including Windows 11.

Why Not B (Install an HSM): A Hardware Security Module (HSM) is a separate device used for cryptographic functions and is not related to TPM on the motherboard.

Why Not C (Perform a clean install): A clean installation will not bypass the TPM 2.0 requirement.

Why Not D (Implement BitLocker): BitLocker requires TPM but does not resolve its absence or lack of activation.

Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

Why Not D (Print server): A print server manages print jobs but doesn’t enforce authentication.

Degraded performance that occurs only during business hours strongly suggests network congestion caused by simultaneous data and voice traffic. According to CompTIA Core 1 (220-1201) networking objectives, combining voice (VoIP) and data traffic on the same network without proper segmentation can lead to latency, jitter, and packet loss, especially during peak usage periods.

Implementing VLANs (Virtual Local Area Networks) allows administrators to logically separate voice and data traffic, enabling better traffic management and prioritization. VLANs also support Quality of Service (QoS) policies that ensure time-sensitive voice traffic is prioritized over standard data traffic, improving call quality and overall performance.

Replacing switches with higher-capacity models is costly and unnecessary if proper traffic segmentation has not yet been implemented. Adding RAM to PCs or VoIP lines does not address network-level congestion. Firmware updates may improve stability but will not resolve sustained performance degradation caused by traffic contention.

CompTIA highlights VLAN implementation as a best practice for environments that use IP phones, especially when performance issues occur during high utilization periods.

Data centers and high-performance servers prioritize stability and fault tolerance. CompTIA A+ identifies ECC (Error-Correcting Code) RAM as the standard memory used in such environments. ECC RAM automatically detects and corrects single-bit memory errors, preventing system crashes, data corruption, and downtime—critical requirements for servers running mission-critical workloads.

ECC memory is commonly paired with registered/buffered modules (RDIMM) for additional stability, but ECC itself is the defining feature required in data center environments. Non-ECC, unbuffered memory is used in consumer desktops where minor memory errors pose minimal risk.

Single-channel memory (B) is simply a configuration and does not imply reliability. Unbuffered RAM (C) is not used in enterprise-grade systems because it lacks error correction and electrical stabilization. RDIMM (D) includes buffering but may come with or without ECC; however, ECC is the key requirement highlighted by the question.

Therefore, the correct answer is ECC RAM.

When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.

Option A:Entering a PIN is only relevant during initial pairing and may not be prompted again.

Option B:Turning off Wi-Fi doesn’t typically affect Bluetooth; they operate on similar frequencies but don’t conflict this way in normal use.

Option D:If Bluetooth were disabled, the device wouldn’t appear at all, not just show as “not connected.”
