What is the maximum number of SATA devices that can be connected to a single port?
A. Incorrect: It suggests a multiplicity that SATA does not support; SATA connections are designed for single-device use.
B. Incorrect: Although SATA can connect two devices in some configurations like with port multipliers, the standard connection allows only one device per port.
C. Incorrect: It implies a level of connectivity that goes beyond what SATA supports for direct point-to-point connections.
D. Correct: SATA is designed to support a single device per port for optimal performance and reliability.
When crimping an RJ45 connector, what should a technician ensure before compressing the connector?
A. Correct: It ensures that the strain relief grips the cable jacket, protecting individual conductors from stress.
B. Incorrect: Twisting together the conductors after insertion does not improve conductivity; proper alignment and crimping do.
C. Incorrect: Tightening contacts with a screwdriver applies to modular plugs, not RJ45 connectors which use a crimp tool for compression.
D. Incorrect: Uneven wires can damage the connector or cause poor connections, defeating the purpose of even wire seating.
What is the primary purpose of airplane mode?
A. Incorrect: It enhances battery life but does not fully capture airplane mode's primary purpose of disabling wireless communication.
B. Incorrect: Although airplane mode supports flight safety rules, its main function is to disable all wireless signals rather than providing a special security feature.
C. Correct: It accurately describes the primary purpose of airplane mode: to disable all wireless communication, including Wi-Fi and Bluetooth.
D. Incorrect: It is turning off mobile data, but it is part of airplane mode, this option does not mention disabling other forms of wireless communication like Wi-Fi and Bluetooth.
What is a primary use case for IaaS?
A. Incorrect: It describes a specific scenario where IaaS can be used but does not capture its primary purpose of deploying and managing virtual machines.
B. Incorrect: It is more aligned with traditional IT operations rather than the cloud-based deployment model offered by IaaS.
C. Incorrect: High-performance computing resources are typically associated with specialized services or platforms designed to handle such demands, not general-purpose IaaS offerings.
D. Correct: It accurately describes the primary use case of Infrastructure as a Service, which involves deploying and managing virtual machines across multiple locations for flexibility and scalability.

C. Incorrect: Managing DNS configurations is the role of a DNS server, not DHCP.
D. Correct: DHCP dynamically assigns IP addresses to devices within a network.
Which statement best describes USB-C accessory mode?
A. Incorrect: It only mentions data transfer and omits charging support.
B. Incorrect: It limits functionality to charging alone, ignoring simultaneous data transfer capability.
C. Correct: USB-C accessory mode supports both charging and data transfer at the same time.
D. Incorrect: Audio output is not a primary function of USB-C accessory mode.
What is the main advantage of using a hypervisor?
A. Incorrect: It increases storage capacity, which is unrelated to a hypervisor's primary function of managing virtual machines.
B. Correct: It allows multiple operating systems to run on a single piece of hardware simultaneously, showcasing the core benefit of virtualization.
C. Incorrect: Improving network performance between VMs is not the main advantage of using a hypervisor; that would be more related to networking configurations or software within the VMs.
D. Incorrect: Providing additional security features for VMs is important but secondary compared to running multiple OSes on one piece of hardware.
Which DDR5 characteristic helps maintain performance as memory signaling speeds increase?
A. Correct: It describes how DDR5 RAM reduces latency through improved signal integrity, enhancing performance.
B. Incorrect: Increased power consumption would hinder rather than enhance performance.
C. Incorrect: Supporting single-channel operation only would limit bandwidth and reduce overall performance compared to dual-channel configurations.

How are A+ Core 1 questions generated?
dotCreds builds A+ Core 1 practice questions from CompTIA documentation, standards, and source-backed references, with official or primary sources preferred first. The questions are written for realistic study practice, not copied from exam dumps.
How are explanations sourced?
Each question includes a source-backed explanation and a link to the documentation or reference used to validate the answer. If an official page is too broad, dotCreds uses a reputable answer-level reference instead of pretending a generic page proves the answer.
What score do I get?
The page tracks today's answered count and accuracy for the 10-question daily set, then saves a 7-day score history on this device so you can see your recent practice trend.
Why use this site?
The site is the fastest way to start A+ Core 1 practice without installing anything. It is built for daily recall, quick weak-topic discovery, and source-backed explanations you can review immediately.
Why use the app when available?
The web page is the quick free sampler. If a dotCreds app is available for A+ Core 1, the app is better for larger banks, focused weak-domain drills, longer review sessions, and mobile study routines.
