CompTIA Exam Objectives 220-1101, Domain 3.1

Answer : B

Reasoning: A docking station is designed to provide a central connection point for multiple peripherals, such as monitors, keyboards, mice, and network cables. It allows users to quickly connect or disconnect all devices by simply docking or undocking their laptop, improving mobility and reducing wear and tear on individual ports.

Why the Other Options Are Incorrect:

A . Serial interfaces:

Serial interfaces are outdated and rarely used in modern laptops or peripherals. They are not practical for facilitating the connection of multiple devices.

C . Network switch:

A network switch is used to connect multiple devices to a network, but it does not simplify the connection of peripherals to a laptop.

D . USB hub:

A USB hub can extend the number of available USB ports but lacks the full functionality of a docking station, such as video output or Ethernet connectivity.

Practical Example:

A user with a laptop, external monitors, keyboard, and mouse can use a docking station to connect all devices with a single action, instead of plugging in each device manually.

CompTIA A+ Exam Objective Alignment:

Answer : C

A firewall monitors and filters incoming and outgoing network traffic based on security rules, protecting the network from unauthorized access and threats.

Why Not A (Switch): A switch connects devices within a network but does not monitor or filter traffic.

Why Not B (Access point): An access point provides Wi-Fi connectivity but does not filter traffic.

Why Not D (Hub): A hub simply broadcasts data to all connected devices without filtering traffic.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.2, network security concepts.

Answer : C

When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.

Option A:Entering a PIN is only relevant during initial pairing and may not be prompted again.

Option B:Turning off Wi-Fi doesn't typically affect Bluetooth; they operate on similar frequencies but don't conflict this way in normal use.

Option D:If Bluetooth were disabled, the device wouldn't appear at all, not just show as ''not connected.''

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.5: Given a scenario, connect and configure accessories and ports of mobile devices.

Answer : D

A blinking orange light typically indicates a failed hard drive in the RAID array. In RAID 1 (mirroring), you can replace the failed drive and rebuild the array without data loss.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 -- RAID configuration and troubleshooting:

'In the event of a hard drive failure in RAID 1, replace the failed disk and allow the array to rebuild using the remaining mirrored disk.'
