220-1101 Exam Dumps - CompTIA A+ Questions and Answers

The first step to recover data from a failing drive is to clone the drive to another one, which means creating an exact copy of the drive’s contents, including the operating system, applications, files, and settings, to a new drive. Cloning the drive can preserve the data and prevent further damage or data loss from the failing drive. Cloning the drive can also allow the technician to boot from the new drive and access the data normally, without needing to reinstall the operating system or the applications12.

The other options are not as effective or relevant as cloning the drive. Accessing the Device Manager may not help with data recovery, as it is a tool that displays and manages the hardware devices and drivers on a PC. The Device Manager may show the status of the failing drive, but it cannot copy or restore the data from it3. Downloading the drive manufacturer’s diagnostic tool may help with identifying and repairing some errors or issues with the drive, but it may not be able to recover the data if the drive is physically damaged or corrupted. The diagnostic tool may also overwrite or erase some data during the repair process, which can make the data recovery more difficult or impossible4. Uninstalling the drive in the Device Manager may not help with data recovery, as it removes the drive from the system and its driver from the operating system. Uninstalling the drive may make the drive inaccessible or unrecognized by the PC, which can prevent the data recovery5. Replacing the drive with a new one may not help with data recovery, as it does not transfer the data from the old drive to the new one. Replacing the drive may also require reinstalling the operating system and the applications, which can take time and effort. Replacing the drive may also discard the old drive, which may still contain some recoverable data.

The MOST efficient next step the technician should complete is to check the printer paper path to locate any obstructions1. The error message “Paper Jam, Jam in fuser” indicates that there is a paper jam in the fuser2. The fuser is one of the parts of a laser printer most likely to fail without giving any explicit message2. 

The printer LCD screen indicates a paper jam in the fuser. The most efficient next step the technician should complete is to check the printer paper path to locate any obstructions. Applying a maintenance kit or replacing the fuser may not be necessary if the issue is caused by a paper jam.

The correct answer is D. Sandboxing.

Sandboxing is a security technique that isolates email attachments in a safe place until the attachments can be scanned for malware. A sandbox is a virtual environment that mimics the operating system and applications of the user, but prevents any changes or damage to the actual system. A sandbox can also monitor the behavior and activity of the attachments and detect any malicious code or actions12.

An approve listing is a security technique that allows only trusted or authorized email senders or domains to be received by the user. An approve listing can help reduce spam and phishing emails, but it does not scan or isolate email attachments for malware3.

A screened subnet is a security technique that creates a buffer zone between the internal network and the internet. A screened subnet uses firewalls and routers to filter and control the traffic that enters and exits the network. A screened subnet can help protect the network from external attacks, but it does not scan or isolate email attachments for malware.

Cross-platform virtualization is a technology that allows running multiple operating systems and applications on the same physical machine. Cross-platform virtualization can help improve efficiency, flexibility, and compatibility, but it does not scan or isolate email attachments for malware.

The first steps that the technician should perform are A. Check the version of the HDMI cable and B. Check the input source.

A possible cause of the problem is that the HDMI cable is not compatible with the 4K resolution of the monitor. HDMI cables have different versions that support different features and bandwidths. For example, HDMI 1.4 supports up to 4K at 30 Hz, while HDMI 2.0 supports up to 4K at 60 Hz1. The technician should check the version of the HDMI cable and make sure it matches the specifications of the monitor and the desktop.

Another possible cause of the problem is that the monitor is not set to the correct input source. The input source is the option that allows the monitor to switch between different video signals from different ports, such as HDMI, DVI, VGA, or DisplayPort2. The technician should check the input source and make sure it is set to HDMI, since that is how the desktop is connected to the monitor. The input source can usually be changed using the buttons or menu on the monitor itself2.

A limited wireless range after replacing the wireless card could indicate that the antenna is not properly connected to the card, or that the antenna is damaged or obstructed. According to the web search results, some possible steps to troubleshoot and verify the antenna’s connection are:

Open the laptop case and locate the wireless card and the antenna wires. Make sure that the wires are securely attached to the card’s connectors, and that they are not loose or broken12.

Check the position and orientation of the antenna. Make sure that it is not blocked by any metal objects, walls, or other sources of interference. Adjust the angle or location of the antenna if possible to improve the signal strength3.

Replace the antenna with a new one or a compatible one from another device. Test the wireless range and performance with the new antenna2.

RFID stands for Radio Frequency Identification, and it is a technology that uses electromagnetic fields to identify and track objects that have RFID tags attached to them. RFID tags are small devices that store information and can be read by RFID readers. RFID is most likely used to control door access because it allows for contactless and convenient authentication of authorized personnel. For example, an employee can use an RFID card or key fob to unlock a door by holding it near an RFID reader installed on the door. The reader will scan the tag and verify its ID number with the access control system, which will grant or deny access based on the predefined rules and permissions. RFID is a common and widely used type of door access control system, as it offers security, efficiency, and flexibility.

The manufacturer’s specifications for the components are the best source of information to determine the appropriate power supply for the workstation. The manufacturer’s specifications will list the power requirements and recommendations for each component, such as the graphics card, the CPU, the hard drives, and the motherboard. By adding up the power consumption of each component, the technician can estimate the total wattage needed for the workstation. The technician should also consider some extra headroom for future upgrades or peak loads. The technician can then choose a power supply that meets or exceeds the total wattage and has the right connectors and form factor for the workstation.

AAA stands for Authentication, Authorization, and Accounting, and it is a framework that provides security services for network access control. Authentication verifies the identity of a user or device that requests access to a network resource. Authorization determines what level of access or privileges are granted to a user or device based on their identity or role. Accounting tracks and records the usage of network resources by users or devices for billing or auditing purposes. RADIUS (Remote Authentication Dial-In User Service) is a protocol that implements AAA functions by communicating with a central server that stores user credentials and policies.

The most likely issue that prevents the user’s mobile device from saving pictures to an external drive at home is that the peripherals are managed via MDM (mobile device management). MDM is a software solution that allows an organization to remotely control, secure, and enforce policies on mobile devices, such as smartphones, tablets, or laptops. MDM can also restrict the access and functionality of the peripherals, such as external drives, cameras, microphones, or printers, that are connected to the mobile devices.

One of the possible reasons why the user’s mobile device can back up classified files to an external hard drive at work but not save pictures to an external drive at home is that the MDM policy allows only authorized peripherals to be used with the mobile device. For example, the MDM policy may require the external drive to have a certain encryption level, a specific serial number, or a valid certificate to be recognized by the mobile device. The external drive at work may meet these criteria, while the external drive at home may not. Therefore, the mobile device can back up the classified files to the external drive at work, but it cannot save the pictures to the external drive at home.

To resolve this issue, the user may need to contact the IT administrator or the MDM provider and request permission to use the external drive at home. Alternatively, the user may need to use a different method to transfer the pictures from the mobile device to the external drive, such as using a cloud service, a wireless network, or a USB cable.

The most likely action that would resolve the issue is to clean the keyboard. Sometimes dust, hair, and other debris can affect keyboard functionality. The technician can try to clean the keyboard as much as possible, which may be enough to get the keyboard back in working order

Port flapping, also known as link flapping, is a situation in which a physical interface on the switch continually goes up and down, causing intermittent connectivity for the devices connected to that port12. Port flapping can be caused by various factors, such as faulty or incompatible cables, hardware issues, configuration errors, or other network problems123.

The network logs show that interface 0/1 on the switch changes its status from up to down and vice versa several times within a short period of time. This indicates that the port is flapping and affecting the network connectivity. The log also shows that the switch was elected as the root bridge, which means that it is the central point of a spanning tree protocol (STP) network. STP is a protocol that prevents loops in a network by blocking some ports and creating a tree-like topology. Port flapping can cause STP to recalculate the topology and change the status of the ports, which can further disrupt the network performance2.

To troubleshoot port flapping, the technician should check the physical and hardware aspects of the device, such as cables, SFPs, gigabit interface converters, and power supplies. The technician should also check the configuration settings of the port, such as auto-negotiation, duplex mode, speed, power-saving features, and smartport. The technician should also check for other network issues that may cause port flapping, such as link synchronization and spanning tree issues123.

The most likely component that is failing and causing the PC to overheat is D. CPU fan. The CPU fan is a vital part of the cooling system that prevents the CPU from overheating by blowing air over the heatsink and dissipating the heat. If the CPU fan is faulty, noisy, or clogged with dust, it can reduce the airflow and cause the CPU temperature to rise12. This can result in poor performance, instability, or shutdowns of the PC.

The other components are less likely to be the cause of overheating. RAM, motherboard, and SSD do not generate as much heat as the CPU and usually do not require fans to cool them down1. They may overheat if there is poor ventilation in the case or if they are defective, but they are not as common as a failing CPU fan.

Therefore, the correct answer is D. CPU fan. This is the most likely component that is failing and causing the PC to overheat.

A sandbox environment is an isolated testing environment where code can be written and tested without impacting other infrastructure. This provides a safe and controlled environment for experimentation and development.

The best option that the technician should do to optimize performance is D. Utilize all channels. This option means that the technician should install the RAM modules in a way that maximizes the number of memory channels that are used by the motherboard. Memory channels are pathways that connect the memory controller to the RAM modules, and they allow data to be transferred between them. The more memory channels that are used, the higher the memory bandwidth and performance1.

DDR5 memory supports up to eight memory channels per module, which is twice as many as DDR42. However, not all motherboards can support eight channels per module, and some may only support four or two channels per module. Therefore, the technician should check the motherboard specifications and manual to determine how many memory channels it supports and how to install the RAM modules accordingly.

For example, if the motherboard supports four channels per module, then the technician should install four RAM modules in slots 1, 3, 5, and 7 to use all 16 available channels. If the motherboard supports two channels per module, then the technician should install eight RAM modules in all slots to use all 16 available channels. If the technician installs fewer modules than the number of slots, then some channels will be left unused and the performance will be lower1.

Three beeps indicate a "base memory read/write test error". Check out "beep codes" for more information.

Reseating the RAM is the best course of action to remediate the issue of three consecutive beeps during boot, as it may indicate a RAM failure or loose connection. By reseating the RAM, the technician can ensure that the connection is secure and the computer should boot normally. References: CompTIA A+ Certification Exam Objectives 1001, 1.9

The correct answers are C. Pickup roller and D. Separation pad.

A pickup roller is a rubber wheel that grabs the paper from the paper tray and feeds it into the printer. A separation pad is a small piece of cork or rubber that prevents more than one sheet of paper from being fed at a time. If the pickup roller or the separation pad is worn out, dirty, or damaged, it can cause the printer to pull multiple sheets of paper instead of a single sheet. This can lead to paper jams, misprints, or wasted paper.

To resolve this issue, a technician should investigate the condition of the pickup roller and the separation pad and replace them if necessary. The technician should also clean the paper tray and make sure the paper is loaded correctly and not stuck together.

A toner cartridge is a component that contains the toner powder used to create the printout on a laser printer. A tractor feed is a mechanism that uses sprockets to move continuous paper through a dot matrix printer. A duplexer is a device that allows a printer to print on both sides of the paper automatically. A fuser is a part of a laser printer that melts the toner onto the paper using heat and pressure. None of these components are related to the issue of pulling multiple sheets of paper from the paper tray.

Metered utilization of cloud resources refers to payments made only for resources that are used. Cloud providers offer a pay-as-you-go model where customers are charged based on their usage of resources. Customers can easily scale up or down their usage of resources as per their needs and only pay for what they use.

The internal antennas are the components that allow the laptop to receive and transmit wireless signals from and to the wireless access point. The internal antennas are usually located inside or around the laptop screen, and they are connected to the wireless network card or adapter by thin wires or cables. If the internal antennas are disconnected, damaged, or misaligned, the laptop may experience wireless connectivity issues, such as low signal strength, limited range, or intermittent connection.

In this scenario, a customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point. This could indicate that the technician accidentally disconnected or damaged the internal antennas during the screen replacement process, and that the laptop is not receiving enough wireless signals from the wireless access point. Therefore, the first thing that the technician should verify is that the internal antennas are properly connected and positioned inside or around the laptop screen.

To verify and reconnect the internal antennas, the technician should follow these steps :

Turn off the laptop and disconnect it from any power source or external device.

Remove the battery and any screws that secure the laptop screen bezel.

Carefully pry off the laptop screen bezel and expose the internal antennas.

Check if the internal antennas are intact and securely connected to the wireless network card or adapter. The internal antennas may have different colors or labels, such as black, white, gray, main, aux, or 1, 2.

If the internal antennas are disconnected or loose, reconnect them to the corresponding connectors on the wireless network card or adapter. Make sure that they snap into place and that there is no gap or bend in the wires or cables.

If the internal antennas are damaged or broken, replace them with compatible ones. Make sure that they have the same length and shape as the original ones.

Realign and reposition the internal antennas inside or around the laptop screen. Make sure that they do not interfere with any other component or cable, and that they follow the original path and direction.

Reattach the laptop screen bezel and secure it with screws.

Reinsert the battery and turn on the laptop.

Test the wireless connectivity and performance of the laptop.
