Objective 2.3: Explain common logical networking concepts.

RAID 10 combines the benefits of RAID 0 and RAID 1. It uses a striped configuration across multiple disks (similar to RAID 0) to provide high-speed read and write access. Additionally, it also mirrors the striped array onto a second set of drives (similar to RAID 1), providing redundancy in case of a drive failure.

SSH (Secure Shell) encrypts data communications for secure remote login and management of network devices, ensuring all console connections are encrypted.

Why Not B (LDAP): LDAP is used for directory services and does not encrypt by default.

Why Not C (FTPS): FTPS encrypts file transfers, not console communications.

Why Not D (SMTP): SMTP is used for email transmission, not for securing login sessions.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, network security protocols​.

RAID 10 (also known as RAID 1+0) combines the features of RAID 1 (mirroring) and RAID 0 (striping) to provide both redundancy and performance enhancements. This configuration requires a minimum of four drives and offers fast data access through striping while ensuring data redundancy through mirroring. RAID 10 is ideal for environments where both data integrity and performance are critical, such as financial databases.

Syslog is used to log system events and tasks performed by applications, providing a centralized record of activity.

Why Not A (Fileshare): Fileshares store files but are not designed for event logging.

Why Not C (Database): Databases can store logs but are not a logging mechanism themselves.

Why Not D (SAN): A SAN is a storage solution, not a logging tool.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.6, system monitoring and logging​.

If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.

Why Not A (Replace the hard drive's USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.

Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.

Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, storage troubleshooting​.

The digitizer converts touch inputs into digital signals, enabling touch functionality on a monitor. This component is essential for touch screens to process user input and is covered under the CompTIA A+ Core 1 objective on display technologies for mobile devices​.

After replacing a hot-swappable hard drive in a RAID 5 array, the array must rebuild the data onto the new drive. This process involves reading data from the remaining drives and writing it to the new drive to restore full redundancy. The performance decrease is due to the intensive read and write operations necessary to rebuild the RAID array, which can take several hours depending on the size of the drives and the amount of data.

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.

Since the issue of the network connection dropping has been replicated on a known-good workstation using the same network cable, it suggests that the problem may not be with the individual workstations or the cable. The next logical step is to check for external interference, such as electrical or wireless interference that could be disrupting the network connection.

C. Validate the environment for external interference: External factors, such as nearby electronic devices or poor cabling, can cause intermittent network drops. Checking for interference would be a prudent next step.

Why the other options are incorrect:

A. Add new network hardware to reduce congestion: There’s no evidence that network congestion is the issue, and adding new hardware without identifying the cause is premature.

B. Assign a static IP to the impacted workstations: The issue appears to be related to the physical network connection or environment, not IP addressing.

D. Check the network logs for evidence of port flapping: Port flapping occurs when a network port rapidly switches between up and down states. While checking logs could provide information, external interference is a more likely culprit given the symptoms.

This issue is part of the Networking Troubleshooting domain in the CompTIA A+ Core 1 exam​.

Reducing the frequency of location checks using cellular location services will consume less battery power while still allowing the user to view weather forecasts while travelling. The other options may not solve the battery drain issue while using the weather application.

Configuring less frequent location checks using cellular location services is the best option for the salesperson to view weather forecasts while traveling without draining the battery too quickly. References: https://www.makeuseof.com/tag/5-ways-improve-battery-life-android-phone/

A docking station is a hardware accessory that allows laptops to connect to multiple peripherals and devices with a single connection. A docking station with DisplayPort would provide the necessary connectivity for the dual monitors, and it can also support the required peripherals such as the keyboard, mouse, and speakers. In addition, it will provide a wired network connectivity for faster and more reliable network access.

Reasoning: A cable tester capable of testing Power over Ethernet (PoE) functionality can verify whether the switchport is providing the required power to the phone. This tool measures both the presence of data and the voltage or wattage being provided through the Ethernet cable.

This is the most effective way to confirm that PoE is available on the port.

Why the Other Options Are Incorrect:

A. Network tap:

A network tap is primarily used to monitor network traffic, not to test for PoE availability. It cannot verify if power is being supplied through the Ethernet cable.

C. Loopback plug:

A loopback plug is used to test the functionality of a network port by creating a loop for transmitted and received signals. It does not measure or verify PoE availability.

D. Toner probe:

A toner probe is used for tracing and identifying network cables. It cannot test for PoE functionality.

Practical Example:

A PoE phone might not turn on due to a misconfigured or faulty switchport. Using a cable tester capable of measuring PoE would help the technician determine if the switchport is supplying sufficient power to the phone.

CompTIA A+ Exam Objective Alignment:

Objective 2.1: Identify common networking hardware and tools, including PoE-enabled devices and cable testers.
