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

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 baseline documentation says the valid network range ends at 192.168.232.255, but the user’s gateway is 192.168.233.1, which is outside the permitted network range. CompTIA A+ emphasizes that devices must have a gateway inside their own subnet.

Given a mask of 255.255.255.0, the user’s subnet is 192.168.223.x, so the gateway must be in 192.168.223.x, not 192.168.233.x.

DNS settings are public and acceptable. The IP address and subnet mask are valid within the documented address space.

Therefore, the incorrect setting is the gateway, which prevents external routing. Correcting it resolves the connection issue, matching CompTIA’s routing and TCP/IP troubleshooting procedures.

ECC (Error-Correcting Code) RAM is commonly used in servers because it can detect and correct memory errors, providing greater stability and reliability for mission-critical environments.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.2 – Types of RAM:

“Servers often require ECC memory, which can detect and correct single-bit errors, preventing data corruption and increasing system reliability.”

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.

A Virtual Private Network (VPN) creates an encrypted, secure tunnel across a public or untrusted network. It uses authentication credentials to ensure that only authorized users can connect, keeping data safe from interception.

Comprehensive and Detailed Explanation:

Laptop Wi-Fi antennas run through the display bezel and connect via small coaxial clips. After motherboard replacement, these are often not fully seated, causing weak or unstable Wi-Fi.

CompTIA Concepts:

Laptop hardware troubleshooting

Antenna connector checks after repair

WLAN performance issues caused by antenna misalignment

To add additional wired network devices in a simple and cost-effective manner, the best solution is an unmanaged switch. CompTIA A+ explains that unmanaged switches require no configuration, provide instant port expansion, and operate using plug-and-play functionality. This makes them ideal for home offices where the user wants more Ethernet ports without dealing with administrative overhead or complex setup.

An unmanaged switch automatically forwards traffic using MAC addresses, expanding the network without altering IP configuration or security settings. It is inexpensive compared to other networking equipment and requires no firmware updates, VLAN management, or routing knowledge.

A DSL modem or cable modem provides internet service but does not increase the number of available network ports beyond the single LAN port commonly offered. A firewall controls traffic but does not expand physical connectivity. Therefore, neither modem nor firewall options meet the requirement of adding more wired devices.

Thus, the unmanaged switch is the simplest, cheapest, and most practical choice for expanding connectivity in a home office environment.

In networked print environments, print jobs are processed through a system service called the print spooler. CompTIA A+ stresses that when shared printers fail due to job overload, the problem often lies with a hung or overloaded spooler service, especially when multiple jobs are sent simultaneously. The spooler queues, organizes, and processes print jobs; if it becomes overwhelmed or corrupted, printing stops completely even though the network and printer hardware remain functional.

After verifying network connectivity—as the question states— the next logical and CompTIA-aligned troubleshooting step is to restart the spooler service (D). Restarting it clears stuck or corrupt jobs, reinitializes print processing, and restores functionality without requiring a full server reboot or reinstallation of drivers.

Rebooting the server (A) may work but is unnecessarily disruptive and affects multiple services. Reinstalling printer drivers (B) is only warranted for driver corruption issues and is not the first step for spooler congestion. Resetting the printer to factory defaults (C) erases settings and is far too drastic for a simple print queue issue.

Therefore, the most efficient and technically correct action is restarting the print spooler service, restoring printing immediately while maintaining normal server operations.

PoE (Power over Ethernet) allows both data and electrical power to be delivered over the same Ethernet cable. A PoE injector adds power to Ethernet cables for devices that need it.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 – Networking hardware:

“Power over Ethernet (PoE) technology and PoE injectors enable both power and data transmission to compatible network devices like access points and IP cameras.”

A managed switch allows an administrator to enable or disable individual ports as part of network security and management. If a port on a managed switch has been disabled, the device connected to that port will lose connectivity, which matches the scenario described.
