CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 431:

  An organization has some computers running macOS and some computers running Windows. The computers running macOS also need to run a piece of software that is only available on Windows. Which of the following BEST describes the solution for running Windows software on a computer running macOS?

  A. Operating system spoofing

  B. Remote software provisioning

  C. Indirect software implementation

  D. Cross-platform virtualization

  Correct Answer: D

  Cross-platform virtualization would be the best solution for running Windows software on a computer running macOS. This involves running a virtual machine (VM) on the macOS computer, which emulates a Windows environment and allows the Windows software to be installed and run within the VM. Cross-platform virtualization allows a computer running macOS to run Windows software. It involves creating a virtual machine on the macOS computer and installing a Windows operating system on it.

• Question 432:

  Which of the following is a valid use for PaaS?

  A. Off-site backups

  B. An application development environment

  C. A virtual server installation and configuration model

  D. A web application for asset management

  Correct Answer: B

  PaaS (Platform as a Service) is a cloud computing model in which a provider offers a platform that allows developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure. An application development environment is a valid use for PaaS. References: CompTIA A+ Certification Exam Objectives 1001, 1.7

• Question 433:

  While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is extremely polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?

  A. The channel is reserved for licensed band use.

  B. The channel selection is defective; contact the manufacturer.

  C. The channel must be unlocked by the vendor.

  D. The device requires a firmware update to unlock the channel.

  Correct Answer: A

  The 2 band is subdivided into up to 14 channels, spaced at 5 MHz intervals from 2412 MHz up to 2484 MHz. Wi-Fi requires bandwidth of approximately 20 MHz, not 5 MHz. Consequently, a site designer needs to choose the channels that do not overlap. On a WLAN where only the first 11 channels are available, channels 1, 6, and 11 can be selected as non-overlapping. Note: In the Americas, regulations permit the use of channels 1-11 only, while in Europe, channels 1-13 are permitted. In Japan, all 14 channels are permitted.

• Question 434:

  A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor The technician sees both a flashing green LED and a flashing orange LED on the workstation's NIC. Which of the following should the technician do FIRST?

  A. Check the RJ45 end connectors, the jacks, and the ends of the run of the Cat 5 UTP cable for loose connections, pinched bends, and visible damage.

  B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run.

  C. Replace the entire run of Cat 5 UTP cable with Cat 5 STP cable.

  D. Upgrade the entire cable run to multimode fiber.

  Correct Answer: A

  The flashing green LED on the NIC indicates that the NIC is receiving power, and the flashing orange LED indicates that the NIC is attempting to establish a network connection. Since the technician installed a Cat 5 UTP cable for this connection, the issue is most likely related to the cable or the connectors. Therefore, the technician should first check the RJ45 end connectors, the jacks, and the ends of the run of the Cat 5 UTP cable for loose connections, pinched bends, and visible damage.

• Question 435:

  A user acquired a new workstation and is attempting to open multiple targe Excel files simultaneously. The user is not experiencing the expected performance when executing such large requests. Which of the following should a technician do FIRST?

  A. Increase the swap partition.

  B. Upgrade the CPU in the workstation.

  C. Upgrade the power supply in the workstation.

  D. Upgrade the RAM in the workstation.

  Correct Answer: D

  Opening multiple large Excel files simultaneously requires a large amount of RAM. Upgrading the RAM in the workstation should improve performance. References: CompTIA A+ Certification uide, Ninth Edition, Chapter 9

• Question 436:

  Which of the following should the data center hardware technician implement to ensure maximum uptime for customers' virtual machines?

  A. Line conditioner

  B. AC voltage regulator

  C. Uninterruptible power supply

  D. Cloud storage backup

  Correct Answer: C

  An uninterruptible power supply (UPS) can help ensure maximum uptime for customers' virtual machines by providing a backup power source in case of a power outage or other power-related issues. A line conditioner and AC voltage regulator are designed to stabilize the power supply, but do not provide backup power. Cloud storage backup is a way to backup data, but does not directly impact uptime. References: CompTIA A+ Certification Exam: Core 1 - Page 159

• Question 437:

  A customer reports that access to the network fileshare has become much slower than usual, but local applications do not seem to have trouble. The technician checks the download bandwidth and finds no issues. Which of the following should the technician check NEXT?

  A. Level of network utilization

  B. Customer use of two-factor authentication

  C. Amount of local drive space

  D. RAID array drive health

  Correct Answer: A

  The technician should check the level of network utilization to determine if there is an excessive amount of traffic that may be causing the slow access to the network fileshare. This can be done using network monitoring tools to track the amount of data being transmitted on the network. References: CompTIA A+ Certification Exam Objectives 1001, 2.9

• Question 438:

  Which of the following would MOST likely be used to obtain electronic images of a large number of printed documents?

  A. NFC device

  B. ADF/flatbed scanner

  C. Camera/webcam

  D. QR scanner

  Correct Answer: B

  ADF/flatbed scanner would most likely be used to obtain electronic images of a large number of printed documents. References: CompTIA A+ Certification uide, Exam 220-1001, Page 351

• Question 439:

  A technician needs to recommend an internet connection for a customer who travels around the world and wants to have connectivity while visiting remote camping locations. Some of the locations the customer visits have limited or unreliable cellular service. Which of the following connection types should the technician recommend?

  A. Satellite

  B. DSL

  C. Fiber D. Hotspot

  Correct Answer: A

  The connection type that the technician should recommend is Satellite. Satellite internet is a good option for people who travel around the world and want to have connectivity while visiting remote camping locations. It works by using terminals

  which can give you internet access in remote locations as long as they have a line of sight to the satellite in orbit above12.

  Since the customer travels to remote camping locations with limited or unreliable cellular service, the best recommendation is satellite internet connection. Satellite internet uses a dish to connect to satellites orbiting the earth, which can

  provide coverage anywhere in the world as long as there is a clear line of sight to the satellite. This is especially useful in remote areas where traditional terrestrial connections are not available. References:

  CompTIA A+ Certification Exam Objectives - 220-1001: 1.6 Given a scenario, evaluate connection type and bandwidth.

• Question 440:

  A technician is setting up a new desktop computer and will be installing the hard drive directly on the motherboard without using cables to connect it. Which of the following will the technician be installing?

  A. Thunderbolt

  B. eSATA

  C. M.2

  D. SCSI

  Correct Answer: C

  M.2 is a form factor for solid-state drives (SSDs) that enables direct attachment to the motherboard without the need for cables. Thunderbolt is a high-speed interface that supports data transfer, video output, and charging. eSATA is an external interface for connecting SATA devices. SCSI is an older interface standard for connecting hard drives, printers, and other peripherals. Installing a hard drive directly on the motherboard without using cables is usually done with an M.2 slot. References: CompTIA A+ Certification uide, Ninth Edition, Chapter 5
