At ValidExamDumps, we consistently monitor updates to the CompTIA 220-1101 exam questions by CompTIA. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the CompTIA A+ Certification Exam Core 1 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by CompTIA in their CompTIA 220-1101 exam. These outdated questions lead to customers failing their CompTIA A+ Certification Exam Core 1 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the CompTIA 220-1101 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A computer that contains critical data has not been backed up and will not boot past a S. M.
The technician should run diagnostics on the faulty hard drive using a boot disk first when a computer that contains critical data has not been backed up and will not boot past a S.M.A.R.T. error that indicates imminent hard disk failure.

A customer's Windows tablet PC was dropped and is no longer responding to touch input on the left half of the screen. The screen protector has several scratches. but the glass is not broken. Which of the following should a technician do to diagnose the issue?
The digitizer is the component that converts the touch input into electrical signals that are processed by the tablet. If the digitizer is damaged or malfunctioning, it may not register the touch input correctly or at all. The technician can test the digitizer using a diagnostic tool or by replacing it with a known good one. Updating the device drivers, replacing the damaged screen protector, or performing a factory reset are unlikely to fix the issue, as they do not address the hardware problem.
A technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots_ When the technician tries to tum on the laptop, the computer starts beeping and does not pass POST The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. Which of the following is the most likely cause of this Issue?
Memory modules are physical components that store data and instructions for the computer to access and process. Memory modules have different specifications and features, such as type, speed, capacity, voltage, and form factor. These specifications and features must be compatible with the motherboard and the processor of the computer, otherwise the memory modules may not work properly or cause errors.
In this scenario, the technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots. DDR3 stands for Double Data Rate 3, and it is a type of memory technology that offers faster performance and lower power consumption than its predecessors. DDR3 RAM modules have different variants, such as DDR3L, DDR3U, or DDR3R, which have different voltage requirements. For example, DDR3L operates at 1.35V, DDR3U operates at 1.25V, and DDR3R operates at 1.5V.
When the technician tries to turn on the laptop, the computer starts beeping and does not pass POST. POST stands for Power-On Self-Test, and it is a process that checks the hardware components and functionality of the computer before loading the operating system. If POST detects an error or a failure, it may produce a series of beeps or codes to indicate the problem. The number and pattern of beeps or codes may vary depending on the manufacturer or model of the computer.
The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. This means that the motherboard is not receiving enough power from the memory module to operate normally. This could indicate that the memory module is not compatible with the motherboard or the processor, or that it is defective or damaged. The most likely cause of this issue is that the technician installed an unsupported memory module that has a lower voltage than what the motherboard or the processor requires.
To resolve this issue, the technician should remove the newly installed RAM module and replace it with a compatible one that has the same voltage as the existing ones. The technician should also check the specifications and features of the motherboard and the processor to ensure that they support the type, speed, capacity, and form factor of the memory modules. The technician should also follow proper safety precautions when handling memory modules, such as wearing an anti-static wrist strap, avoiding physical damage or static discharge, and aligning the notches correctly.
New memory modules were installed in several Windows desktops but some users are still reporting performance issues. Upon investigation, a systems administrator notices the desktop has not recognized the new memory modules. Which of the following should the systems administrator perform to help resolve this issue?
To resolve the issue of new memory modules not being recognized, the systems administrator should configure appropriate settings within the BIOS. This can include enabling memory mapping or setting memory speed and timings. Reference: CompTIA A+ Certification Exam Objectives, 220-1001 Section 1.8
Configure appropriate settings within the BIOS. If new memory modules were installed in several Windows desktops but some users are still reporting performance issues and the desktop has not recognized the new memory modules, the systems administrator should configure appropriate settings within the BIOS to help resolve this issue.
Which of the following allows for a beam of light to transmit data through a flexible cable?
Single-mode fiber uses a beam of light to transmit data over long distances through a very thin, flexible cable. It is commonly used for high-speed data transmission across wide areas, such as between buildings or over long distances within a network. Single-mode fiber offers a higher bandwidth and longer distance capabilities compared to other types of fiber optics.
D . Single-mode fiber: Transmits data using light through a fiber optic cable, making it ideal for long-distance communication.
Why the other options are incorrect:
A . Coaxial: Coaxial cables use electrical signals, not light, to transmit data.
B . HDMI: HDMI (High-Definition Multimedia Interface) is used for transmitting audio and video signals but does not use light for data transmission.
C . Thunderbolt: Thunderbolt cables transmit data using electrical signals and are typically used for high-speed data transfer and display connections.
This falls under the Networking and Hardware domain in the CompTIA A+ Core 1 exam.
