CompTIA 220-1102 Online Questions & Answers

• Question 581:

  A web developer installs and launches a new external web server. Immediately following the launch, the performance of all traffic traversing the firewall degrades substantially. Which of the following considerations was overlooked?

  A. OS compatibility
  B. Quality of service
  C. 32- vs. 64-bit architecture
  D. Storage requirements
  B. Quality of service

  ---

  Explanation

  The performance degradation following the launch of a new external web server suggests that Quality of Service (QoS) considerations were overlooked. QoS settings help prioritize traffic to ensure that critical services like web servers receive the bandwidth they need without negatively impacting the overall network performance. Without proper QoS configuration, the new server's traffic could overwhelm the firewall, leading to widespread performance issues.

• Question 582:

  A user reports a PC is running slowly. The technician suspects it has a badly fragmented hard drive. Which of the following tools should the technician use?

  A. resmon exe
  B. msconfig.extf
  C. dfrgui exe
  D. msmfo32.exe
  C. dfrgui exe

  ---

  Explanation

  dfrgui.exe is a built-in tool in Windows that can be used to defragment a hard drive. Defragmenting a hard drive can improve its performance by rearranging the data on the hard drive so that files are stored in contiguous blocks, which can improve the speed at which the data can be read from the drive. When a hard drive is badly fragmented, it can cause the PC to run slowly as the computer has to work harder to access the scattered data. Therefore final answer is

  C.

• Question 583:

  A help desk technician runs the following script: Inventory.py. The technician receives the following error message:

  How do you want to Open this file?

  Which of the following is the MOST likely reason this script is unable to run?

  A. Scripts are not permitted to run.
  B. The script was not built for Windows.
  C. The script requires administrator privileges,
  D. The runtime environment is not installed.
  D. The runtime environment is not installed.

  ---

  Explanation

  The error message is indicating that the script is not associated with any program on the computer that can open and run it. This means that the script requires a runtime environment, such as Python, to be installed in order for it to execute properly. Without the appropriate runtime environment, the script will not be able to run.

• Question 584:

  A customer called the help desk to report that a new USB CD drive is not working. Which of the following tools should the technician use to diagnose the issue?

  A. lusrmgr.msc
  B. devmgmt.msc
  C. certmgr.msc
  D. perfmon.msc
  B. devmgmt.msc

  ---

  Explanation

• Question 585:

  A user reports a computer is running slow. Which of the following tools will help a technician identity the issued

  A. Disk Cleanup
  B. Group Policy Editor
  C. Disk Management
  D. Resource Monitor
  D. Resource Monitor

  ---

  Explanation

  Resource Monitor is a Windows utility that can be used to monitor and analyze the system resources and processes running on a computer. It can be used to identify and troubleshoot any issues that might be causing the computer to run slowly, such as CPU usage, memory usage, disk I/O, and network usage.

• Question 586:

  Once weekly a user needs Linux to run a specific open-source application that is not available for the currently installed Windows platform. The user has limited bandwidth throughout the day. Which of the following solutions would be the MOST efficient, allowing for parallel execution of the Linux application and Windows applications?

  A. Install and run Linux and the required application in a PaaS cloud environment
  B. Install and run Linux and the required application as a virtual machine installed under the Windows OS
  C. Use a swappable drive bay for the boot drive and install each OS with applications on its own drive Swap the drives as needed
  D. Set up a dual boot system by selecting the option to install Linux alongside Windows
  B. Install and run Linux and the required application as a virtual machine installed under the Windows OS

  ---

  Explanation

  The user should install and run Linux and the required application as a virtual machine installed under the Windows OS. This solution would allow for parallel execution of the Linux application and Windows applications2. The MOST efficient solution that allows for parallel execution of the Linux application and Windows applications is to install and run Linux and the required application as a virtual machine installed under the Windows OS. This is because it allows you to run both Linux and Windows together without the need to keep the Linux portion confined to a VM window 3.

• Question 587:

  A technician is tasked with configuring a computer for a visually impaired user. Which of the following utilities should the technician use?

  A. Device Manager
  B. System
  C. Ease of Access Center
  D. Programs and Features
  C. Ease of Access Center

  ---

  Explanation

  The Ease of Access Center is a built-in utility in Windows that provides tools and options for making a computer easier to use for individuals with disabilities, including the visually impaired. In the Ease of Access Center, the technician can turn on options like high contrast display, screen magnification, and screen reader software to help the user better interact with the computer.

• Question 588:

  Which of the following command-line tools will delete a directory?

  A. md
  B. del
  C. dir
  D. rd
  E. cd
  D. rd

  ---

  Explanation

  To delete an empty directory, enter rd Directory or rmdir Directory . If the directory is not empty, you can remove files and subdirectories from it using the /s switch. You can also use the /q switch to suppress confirmation messages (quiet mode).

• Question 589:

  A technician is troubleshooting a PC that is unable to perform DNS lookups. Utilizing the following firewall output:

  

  Which of the following ports should be opened to allow for DNS recursion?

  A. 1
  B. 53
  C. 80
  D. 123
  E. 445
  B. 53

  ---

  Explanation

  DNS (Domain Name System) lookups are essential for translating human-friendly domain names into IP addresses that computers use to communicate. DNS typically uses port 53 for its communication. In the provided firewall output, various

  ports are either allowed or blocked for outgoing traffic. For DNS recursion, which is the process of resolving domain names to IP addresses, port 53 must be open. Port 53: This is the standard port used by DNS for queries and responses.

  The fact that it is currently blocked (as per the firewall output) is the reason why DNS lookups are failing. Opening port 53 will allow the DNS requests to pass through the firewall, enabling the resolution of domain names to IP addresses.

  Other ports mentioned in the output are used for different services and protocols:

  Port 1 is generally not used for standard services. Port 445 is associated with SMB (Server Message Block) for file sharing in Windows environments. Port 123 is used by NTP (Network Time Protocol) for time synchronization. Port 80 is used

  for HTTP traffic, which is web traffic but not related to DNS lookups.

• Question 590:

  A new employee was hired recently. Which of the following documents will the new employee need to sign before being granted login access to the network?

  A. MSDS
  B. EULA
  C. UAC
  D. AUP
  D. AUP

  ---

  Explanation

  A new employee will need to sign an AUP before being granted login access to the network. An AUP is an Acceptable Use Policy that defines the rules and guidelines for using network resources and services in an organization. An AUP typically covers topics such as security, privacy, ethics, compliance and liability issues related to network usage. An AUP helps protect the organization and its users from legal, regulatory and reputational risks associated with network activities. An MSDS is a Material Safety Data Sheet that provides information about hazardous substances and how to handle them safely. An MSDS is not related to network access or usage. A EULA is an End User License Agreement that specifies the terms and conditions for using a software product or service. A EULA is usually provided by software vendors or developers and does not apply to network access or usage in general. A UAC is a User Account Control that is a security feature that prompts users for permission or confirmation before performing certain actions that require elevated privileges or affect system settings. A UAC is not a document that needs to be signed by users but a mechanism that helps prevent unauthorized changes or malware infections on a system.
