220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2026)

An eSIM (embedded SIM) allows users to change carriers and provision new cellular service without installing any physical hardware. It is managed via software and is ideal for international travelers who need to switch providers quickly.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Install and configure mobile device network connectivity:

" eSIMs provide carrier flexibility by enabling remote provisioning and profile switching, making it possible to connect to different networks without a physical SIM card. "

CompTIA A+ teaches that RAID 6 is the RAID level that uses double parity, allowing the array to survive the failure of two drives simultaneously. RAID 6 stripes data across all disks like RAID 5 but stores two independent sets of parity information, making it far more fault-tolerant.

RAID 0 has no parity and provides only performance. RAID 1 mirrors data but uses no parity. RAID 5 uses single parity and can tolerate only one disk failure. Because the question explicitly asks for double parity, only RAID 6 is correct.

RAID 0 (striping) provides the fastest read (and write) speeds at the lowest cost, as all disk capacity is used for storage and performance. However, it offers no redundancy.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – RAID types:

" RAID 0 stripes data across multiple disks, offering the best performance and lowest cost but no fault tolerance. "

An IDE hard drive uses a Molex connector for power. This 4-pin connector is a standard for older drives.

Why Not A (F type): F type connectors are used for coaxial cables in video and internet applications.

Why Not B (SC): SC connectors are for fiber optic cables.

Why Not D (Lightning): Lightning connectors are for Apple devices.

When both charging and dock-connected peripherals fail at the same time, the problem is most likely with the dock itself or its internal controller circuitry rather than the laptop’s operating system or a single peripheral device. The technician has already verified key prerequisites: the dock has power, the laptop ports show no physical damage, and system firmware (BIOS/UEFI) is current. Those checks reduce the likelihood of a simple firmware incompatibility or a damaged laptop connector.

In CompTIA A+ troubleshooting methodology, the next step is to substitute with a known-good component to isolate the fault quickly. Replacing (or testing with) another dock confirms whether the original docking station has failed. If the replacement dock restores charging and peripherals immediately, the root cause is confirmed without unnecessary invasive actions.

Switching the power supply could be a valid step if power was questionable, but the prompt states the dock already has power and still provides no function—pointing to dock failure. Reinstalling the OS is excessive and unlikely because charging through a dock is not primarily OS-dependent. Rolling back BIOS updates is also not indicated because the issue persists despite current firmware and there is no evidence the BIOS update caused it.

An SSD (Solid-State Drive) is the correct choice because it stores data using flash memory (NAND) and is commonly available in large capacities suitable for operating systems, applications, and mass storage. In CompTIA A+ Core 1 terms, SSDs contain no moving parts, which makes them faster and more reliable than mechanical drives for many workloads. They provide significantly improved read/write performance, lower latency, reduced heat output, and better shock resistance—important for both desktops and especially laptops. SSDs are also widely used in modern systems via SATA or NVMe (PCIe) interfaces, with NVMe offering the highest performance for large data transfers.

The other options do not match “flash memory”: DVD-RW is optical media with limited capacity and slower speeds, intended for removable storage rather than large-volume primary storage. An HDD can store large volumes of data but uses magnetic platters and moving heads, not flash memory. Tape is also magnetic media, typically used for backups and archival storage, and while it can store large amounts, it does not use flash and is designed for sequential access rather than fast random access. Therefore, SSD is the best answer.

DHCP Dynamic Host Configuration Protocol is the service that automatically assigns IP addresses and other essential network settings to devices when they join a network. Instead of manually configuring each device with an IP address, subnet mask, default gateway, and DNS servers, a DHCP server provides these settings dynamically from a defined address pool. This reduces configuration errors, prevents IP conflicts, and makes network administration easier—especially in environments with many devices or frequent changes. In the DHCP process, a client broadcasts a request, the DHCP server offers an address, the client requests that offered address, and the server acknowledges it, granting the device a lease for a specific period. The lease can be renewed, and administrators can also configure reservations to always give the same IP to a particular device based on its MAC address.

DNS is used for resolving hostnames to IP addresses, not assigning them. SMTP is for sending email between mail servers and clients. SNMP is used for monitoring and managing network devices. Therefore, DHCP is the correct service for automatically assigning IP addresses.

Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

Why Not D (Print server): A print server manages print jobs but doesn’t enforce authentication.
