If performance isnot a primary concernand the user requireslarge, cost-effective storage, a2TB 5400rpm SATA HDDis ideal. It offers high capacity at a lower price point than SSDs and faster HDDs.
Option A:NVMe drives offer exceptional speed but are significantly more expensive per GB and not necessary when read/write speed is not a concern.
Option B:RAID 1 improves redundancy but cuts usable capacity in half and uses expensive SSDs.
Option D:SAS drives are fast and reliable but are enterprise-grade and expensive overkill for desktop use.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 1.3: Given a scenario, install and configure storage devices.

A docking station allows users to connect multiple peripherals (monitor, keyboard, mouse, etc.) to a laptop with a single connection, reducing cable clutter and improving convenience.

"A docking station enables the use of multiple external devices with a laptop using only one or two connections, making it ideal for office environments." Verified Source:

CompTIA A+ repeatedly highlights that modern motherboards require two power connectors:
* The 24-pin ATX main power connector
* The 4-pin or 8-pin CPU power connector (EPS connector)
If the CPU power connector is missing, the system will not POST, even though other components appear to have power. This is a very common mistake after replacing PSUs and is specifically noted in CompTIA materials as a frequent cause of "no boot" scenarios.
Insufficient wattage usually causes instability, not a total failure to start. RAM is unrelated to powering on.
Redundant PSUs are used in servers, not gaming PCs.
Thus, the missing CPU power connector is the correct diagnosis and matches A+ hardware troubleshooting guidelines.

DHCP normally assigns IP addresses dynamically using timed leases, meaning the address may change after expiration. However, many devices-such as servers, printers, or specialized workstations-require permanent, predictable IP addresses. CompTIA A+ identifies a DHCP reservation as the correct method for assigning a consistent IP while still using DHCP.
A reservation binds a device's MAC address to a specific IP address in the DHCP server. Each time the device requests an address, the DHCP server recognizes the MAC address and issues the same IP. This provides reliability while still allowing centralized management of network addressing.
A lease is temporary and not permanent. An exclusion simply removes certain IP addresses from the assignable pool-it does not assign any device a fixed address. A scope option configures additional network parameters such as DNS, gateway, or WINS settings but does not assign static IPs.
Therefore, a reservation is the correct method to permanently assign an IP address using DHCP without requiring static configuration on the device itself.

If the system reports"Bootable device not found", and the BIOS is configured correctly, the next step is torun diagnostics on the hard driveto check for physical or logical failure. It could be a sign of afailing drive or corrupt boot sector.
Option A:Reformatting the drive would erase data not a diagnostic step.
Option C:RAM does not affect whether a drive is bootable.
Option D:Replacing the drive should only be doneafter diagnostics confirm failure.
