CompTIA 220-1101 Exam With Confidence Using Practice Dumps

Input voltage must be validated to ensure desktop PCs can operate in different regions with varying power standards (e.g., 110V in North America vs. 220V in Europe). Failure to verify input voltage compatibility can lead to hardware damage or operational issues.

Option B (BIOS language support): Incorrect. While language support may be helpful, it is not critical for hardware deployment across regions.

Option C (Supply chain security): Incorrect. This refers to ensuring secure sourcing of components but does not directly impact deployment.

Option D (Power efficiency): Incorrect. Power efficiency may be important for energy savings but is not relevant to regional compatibility.

SAS stands for Serial Attached SCSI, which is a type of interface that connects storage devices to servers or workstations. SAS supports both mechanical hard disk drives (HDDs) and solid state drives (SSDs), but not other types of storage devices, such as NVMe M.2, mSATA, or optical drives12.

RAID stands for Redundant Array of Independent Disks, which is a method of combining multiple storage devices into a logical unit that provides improved performance, reliability, or both. RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping), which means that data is written across two or more striped sets of mirrored drives34.

Therefore, the only type of storage device that the technician can install in a server that only has SAS connectors and wants to use RAID 10 is mechanical HDDs. Mechanical HDDs use spinning platters and moving heads to store and access data, and they are usually cheaper and have larger capacities than SSDs, but they are also slower and more prone to failure .

DHCP (Dynamic Host Configuration Protocol) is a protocol that allows a device to automatically obtain an IP address and other network settings from a DHCP server, such as a home router. This simplifies the network configuration and avoids IP address conflicts. DHCP is a common requirement for home networks that have multiple devices that need Internet access.

A gateway is a device that connects two different networks, such as a home network and the Internet. A gateway usually performs routing functions, which means it determines the best path for packets to reach their destination. A gateway also often performs NAT (Network Address Translation), which allows multiple devices on a home network to share a single public IP address. A gateway is a necessary requirement for home networks that need Internet access.
