Tools
This tool is used to attach an RJ‑45 connector to the end of a stranded patch cable by pressing the pins through the wire insulation to form a solid electrical connection.
What is a crimper?
This software layer, also called a Virtual Machine Monitor (VMM), allows a host computer to run multiple guest operating systems simultaneously.
What is a hypervisor?
A laser printer shows faint, unfused toner that easily wipes off the page. Which component likely needs replacement?
What is the fuser unit?
This RAID level stripes data across multiple drives for maximum performance but provides no redundancy, meaning a single disk failure destroys the entire array.
What is RAID 0?
This 802.11 standard operates only in the 5 GHz band and supports high throughput, making it faster than 802.11n.
What is 802.11ac?
This tool is used to secure each conductor into an Insulation Displacement Connector (IDC) when terminating solid-core network cabling at a wall jack or patch panel.
What is a punch‑down tool?
This type of hypervisor installs directly on server hardware without requiring a host OS, enabling high‑performance virtualization in enterprise environments.
What is a Type 1 hypervisor?
A user reports repeated vertical lines on printed pages. This common defect is usually caused by an issue with this rotating component.
What is the imaging drum?
This RAID level duplicates all data across two drives, offering simple redundancy with a 50% storage overhead.
What is RAID 1?
This Wi‑Fi band offers better range but suffers from more interference because its channels are only 5 MHz wide.
What is the 2.4 GHz band?
Technicians wear this device to prevent accidental electrostatic discharge while working inside a PC.
What is an ESD wrist strap?
One of the five NIST cloud characteristics, this feature allows cloud resources to automatically adjust to spikes or drops in demand.
What is rapid elasticity?
Multiple documents are stuck in the queue and nothing is printing. According to CompTIA A+, what is the first troubleshooting action you should take?
Correct Response: What is to clear or restart the print spooler / queue?
What is to clear or restart the print spooler / queue?
This RAID level uses block‑level striping with distributed parity, offering fault tolerance with at least three disks and more efficient storage than mirroring.
What is RAID 5?
802.11n achieves higher speeds than earlier Wi‑Fi standards by using these two technologies: multiple antennas and combining adjacent channels.
What are MIMO and channel bonding?
Also nicknamed “fox and hound,” this two‑piece tool lets you transmit a signal over a conductor and trace it to its termination in a bundle or patch panel.
What are a tone generator and probe?
When a company obtains exclusive access to development tools, environments, and runtime platforms from a remote data center, this cloud service model is being used.
What is Platform as a Service (PaaS)?
Epson inkjet printers use this print method, where a tiny element flexes to push ink through the nozzles.
What is the piezoelectric print method?
According to the CompTIA A+ practice material, this RAID level becomes completely unusable if any one of its disks fails.
What is RAID 0?
This wireless topology allows stations to dynamically discover one another and forward traffic, creating large coverage areas without many access points.
What is a wireless mesh network (WMN)?
Essential for diagnosing power supply issues, this handheld tool measures voltage, resistance, and current.
What is a multimeter?
When users log in through simple terminals to access desktops hosted on a central virtualization server, this type of environment is in use.
What is VDI (Virtual Desktop Infrastructure)?
When installing and configuring printers for CompTIA A+, you must check this macOS network service that automatically discovers devices like printers on the local network.
What is Bonjour?
This RAID configuration combines striping and mirroring, requires at least four disks, and provides excellent performance with high fault tolerance.
What is RAID 10?
A wireless card must support the same 802.11 standards as this device, which bridges clients to the wired network and broadcasts the SSID.
What is an access point (AP)?
