CompTIA 220-1201 Exam Dumps

The virtualization platform described matches the characteristics of containers. According to CompTIA Core 1 (220-1201) virtualization concepts, containers are lightweight virtualization solutions that share the host operating system and kernel, rather than running separate guest operating systems. This design allows containers to start almost instantly and be deployed rapidly, making them highly efficient and scalable.

Because containers share kernel resources, they use significantly fewer system resources compared to traditional virtual machines. However, this also results in limited isolation, since applications are not fully separated at the OS level. This tradeoff is a defining characteristic of container-based virtualization.

A Type 1 hypervisor runs directly on hardware and hosts fully isolated virtual machines, each with its own operating system, which does not align with the shared OS and kernel described. A virtual machine also includes a full guest OS, leading to slower startup times and greater resource usage. A virtual desktop refers to user desktop virtualization, not application-level virtualization.

CompTIA highlights containers as an example of application virtualization that prioritizes speed, efficiency, and portability over complete isolation.

Cable modems supplied by ISPs connect to the coaxial wall outlet using an F-type connector. CompTIA A+ specifies that F-type connectors are threaded coaxial connectors used in broadband cable internet, cable TV, and some satellite systems. They attach to RG-6 or RG-59 coaxial cable and provide a secure, shielded connection to the cable provider's infrastructure.

The cable modem requires this coaxial uplink to receive downstream and upstream signals from the ISP before converting them into Ethernet on the LAN side.

LC (B) is for fiber optic connectors, not coaxial. RJ45 (C) is an Ethernet connector and is used on the LAN side of the modem---not on the wall uplink. Lightning (D) is an Apple connector and irrelevant to networking hardware.

Thus, the correct connector for the ISP cable modem uplink is F-type.

USB-Cis a versatile connector capable oftransmitting data, video, audio, and power. With standards likeDisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more all through one cable.

Option B (HDMI):Supports video and audio but not general data transfer.

Option C (DisplayPort):Similar to HDMI supports video/audio but not general file transfer.

Option D (VGA):Legacy analog video only no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

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.

Modern motherboards require both the 24-pin ATX connector and a 4-pin or 8-pin CPU power connector. If the CPU power connector is not attached, the motherboard will receive power but the system will not boot. CompTIA A+ specifically lists this as a common mistake after replacing a power supply.

Insufficient wattage may cause instability, but usually the system still attempts to start. RAM does not prevent power-on if missing; instead, the system produces beep codes. Redundant PSUs are used in servers, not standard desktops.

Therefore, the missing CPU power connector is the most likely cause, and this scenario reflects typical troubleshooting steps outlined in A+ hardware diagnostics.
