CompTIA CompTIA Certifications 220-1102 Questions & Answers

• Question 541:

  Which of the following does MFA provide?

  A. Security enhancement

  B. Encryption

  C. Digital signature

  D. Public key infrastructure

  Correct Answer: A

  MFA stands for multi-factor authentication, which is an electronic authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN1. MFA provides security enhancement by making it harder for attackers to compromise the user's identity or credentials, as they would need to obtain more than just the username and password. MFA can also prevent unauthorized access to sensitive data or resources, as well as reduce the risk of identity theft or fraud2.

• Question 542:

  Which of the following environmental factors are most important to consider when planning the configuration of a data center? (Select two).

  A. Temperature levels

  B. Location of the servers

  C. Humidity levels

  D. Noise levels

  E. Lighting levels

  F. Cable management

  Correct Answer: AC

  Temperature and humidity levels are the most important environmental factors to consider when planning the configuration of a data center, as they directly affect the performance, reliability, and energy efficiency of the IT equipment. Excessive heat or moisture can cause overheating, corrosion, condensation, or static electricity, which can damage the hardware and lead to data loss or service disruption. Therefore, data centers need to monitor and control the temperature and humidity levels within the recommended ranges by using various cooling systems, airflow management, and sensors12.

• Question 543:

  A user reports seeing random, seemingly non-malicious advertisement notifications in the Windows 10 Action Center. The notifications indicate the advertisements are coming from a web browser. Which of the following is the best solution for a technician to implement?

  A. Disable the browser from sending notifications to the Action Center.

  B. Run a full antivirus scan on the computer.

  C. Disable all Action Center notifications.

  D. Move specific site notifications from Allowed to Block.

  Correct Answer: D

  The best solution for a technician to implement is to disable the browser from sending notifications to the Action Center. This will prevent the random advertisement notifications from appearing in the Windows 10 Action Center, which can be

  annoying and distracting for the user. The technician can follow these steps to disable the browser notifications1:

  Open the browser that is sending the notifications, such as Microsoft Edge, Google Chrome, or Mozilla Firefox.

  Go to the browser settings or options menu, and look for the privacy and security section. Find the option to manage site permissions or notifications, and click on it. You will see a list of sites that are allowed or blocked from sending

  notifications to the browser and the Action Center. You can either block all sites from sending notifications, or select specific sites that you want to block or allow.

  Save the changes and close the browser settings.

  This solution is better than the other options because:

  Running a full antivirus scan on the computer (B) is not necessary, as the advertisement notifications are not malicious or harmful, and they are not caused by a virus or malware infection. Running a scan will not stop the notifications from

  appearing, and it will consume system resources and time. Disabling all Action Center notifications ?is not advisable, as the Action Center is a useful feature that shows notifications and alerts from various apps and system events, such as

  email, calendar, security, updates, etc. Disabling all notifications will make the user miss important information and reminders, and reduce the functionality of the Action Center. Moving specific site notifications from Allowed to Block (D) is not

  the best solution, as it will only stop the notifications from some sites, but not from others. The user may still receive advertisement notifications from other sites that are not blocked, or from new sites that are added to the Allowed list. This

  solution will also require the user to manually manage the list of sites, which can be tedious and time- consuming.

• Question 544:

  A technician wants to mitigate unauthorized data access if a computer is lost or stolen. Which of the following features should the technician enable?

  A. Network share

  B. Group Policy

  C. BitLocker

  D. Static IP

  Correct Answer: C

  BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices1. BitLocker helps mitigate unauthorized data

  access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled1. Network share, Group Policy, and Static IP are not features that can prevent unauthorized

  data access if a computer is lost or stolen.

• Question 545:

  Which of the following should be documented to ensure that the change management plan is followed?

  A. Scope of the change

  B. Purpose of the change

  C. Change rollback plan

  D. Change risk analysis

  Correct Answer: A

  The scope of the change is one of the elements that should be documented to ensure that the change management plan is followed. The scope of the change defines the boundaries and limitations of the change, such as what is included and excluded, what are the deliverables and outcomes, what are the assumptions and constraints, and what are the dependencies and risks. The scope of the change helps to clarify the expectations and objectives of the change, as well as to prevent scope creep or deviation from the original plan. The scope of the change also helps to measure the progress and success of the change, as well as to communicate the change to the stakeholders and the team

• Question 546:

  Which of the following macOS features can help a user close an application that has stopped responding?

  A. Finder

  B. Mission Control

  C. System Preferences

  D. Force Quit

  Correct Answer: D

  The correct answer is D. Force Quit. Force Quit is a macOS feature that allows users to close an application that has stopped responding. To use Force Quit, users can press and hold Option (or Alt), Command, and Esc (Escape) keys together, or choose Force Quit from the Apple menu in the corner of the screen. A Force Quit window will open, where users can select the application that they want to close and click Force Quit123. References and The web search results provide information about how to force an app to quit on Mac using different methods, such as keyboard shortcuts, mouse clicks, or menu options. The results also explain what to do if the app cannot be forced to quit or if the Mac does not respond. The first result1 is from the official Apple Support website and provides detailed instructions and screenshots on how to force an app to quit on Mac using the keyboard shortcut or the Apple menu. It also explains how to force quit the Finder app and how to restart or turn off the Mac if needed. The second result2 is from the same website but for a different region (UK). It has the same content as the first result but with some minor differences in spelling and wording. The third result4 is from a website called Lifehacker that provides tips and tricks for various topics, including technology.

• Question 547:

  A payroll workstation has data on it that needs to be readily available and can be recovered quickly if something is accidentally removed. Which of the following backup methods should be used to provide fast data recovery in this situation?

  A. Full

  B. Differential

  C. Synthetic

  D. Incremental

  Correct Answer: A

  A full backup does not depend on any previous backups, unlike differential or incremental backups, which only save the changes made since the last backup. A synthetic backup is a type of full backup that combines an existing full backup with incremental backups to create a new full backup, but it still requires multiple backup sets to recover data. Therefore, a full backup is the most suitable for the payroll workstation that needs to have its data readily available and recoverable. You can learn more about the differences between full, differential, incremental, and synthetic backups from this article.

• Question 548:

  A technician is investigating options to secure a small office's wireless network. One requirement is to allow automatic log-ins to the network using certificates instead of passwords. Which of the following should the wireless solution have in order to support this feature?

  A. RADIUS

  B. AES

  C. EAP-EKE

  D. MFA

  Correct Answer: A

  RADIUS is the correct answer for this question. RADIUS stands for Remote Authentication Dial-In User Service, and it is a protocol that provides centralized authentication, authorization, and accounting for wireless networks. RADIUS can support certificate-based authentication, which allows users to log in to the network automatically without entering passwords. RADIUS also provides other benefits, such as enforcing security policies, logging user activities, and managing network access. AES, EAP-EKE, and MFA are not wireless solutions, but rather encryption algorithms, authentication methods, and security factors, respectively.

• Question 549:

  The battery life on an employee's new phone seems to be drastically less than expected, and the screen stays on for a very long time after the employee sets the phone down. Which of the following should the technician check first to troubleshoot this issue? (Select two).

  A. Screen resolution

  B. Screen zoom

  C. Screen timeout

  D. Screen brightness

  E. Screen damage

  F. Screen motion smoothness

  Correct Answer: CD

  Screen timeout is the setting that determines how long the screen stays on after the user stops interacting with the phone. Screen brightness is the setting that determines how much light the screen emits. Both of these settings affect the battery life of the phone, as keeping the screen on longer and brighter consumes more power than turning it off sooner and dimmer. A technician should check these settings first to troubleshoot the issue of low battery life and adjust them accordingly. Screen resolution, screen zoom, screen damage, and screen motion smoothness are not settings that directly affect the battery life or the screen staying on for a long time.
