CompTIA 220-1102 Online Questions & Answers

• Question 671:

  Which of the following is the MOST important environmental concern inside a data center?

  A. Battery disposal
  B. Electrostatic discharge mats
  C. Toner disposal
  D. Humidity levels
  D. Humidity levels

  ---

  Explanation

  One of the most important environmental concerns inside a data center is the level of humidity. High levels of humidity can cause condensation, which can result in corrosion of components and other equipment. Low levels of humidity can cause static electricity to build up, potentially leading to electrostatic discharge (ESD) and damage to components. Therefore, it is crucial to maintain a relative humidity range of 40-60% in a data center to protect the equipment and ensure proper operation.

• Question 672:

  A customer needs to purchase a desktop capable of rendering video.

  Which of the following should the customer prioritize?

  C. GPU
  D. HDMI
  C. GPU

  ---

  Explanation

  For rendering video, the most critical component a customer should prioritize in a desktop is:

  GPU (Graphics Processing Unit): The GPU is specifically designed to handle complex graphics and video rendering tasks. A powerful GPU will significantly improve performance in video rendering applications. NIC (Network Interface Card):

  Important for network connectivity but irrelevant for video rendering. USB: Useful for peripherals but does not impact video rendering capabilities. HDMI: An important output interface for connecting monitors but not crucial for the rendering

  process itself.

• Question 675:

  A user's laptop has been performing slowly and redirecting to unfamiliar websites. The user has also noticed random pop-up windows. Which of the following is the first step a technician should take to resolve the issue?

  A. Scan for malware and ransomware.
  B. Perform a system restore.
  C. Check the network utilization.
  D. Update the antivirus software.
  A. Scan for malware and ransomware.

  ---

  Explanation

  The most likely cause of the user's laptop issues is that it has been infected by some type of malware or ransomware. Malware and ransomware are malicious software that can harm, exploit, or disrupt devices or networks12. They can cause symptoms such as slow performance, browser redirects, pop-up windows, data encryption, or ransom demands12. Therefore, the first step a technician should take to resolve the issue is to scan the laptop for malware and ransomware using a reliable and updated anti- malware tool34. This can help identify and remove any malicious software that may be present on the laptop. Scanning for malware and ransomware is more effective and urgent than the other options because: Performing a system restore may not remove the malware or ransomware, as some of them can persist or hide in the system files or backup copies34. Moreover, a system restore may result in data loss or corruption, as it restores the system to a previous state and deletes any changes made after that point5. Checking the network utilization may not help diagnose or fix the problem, as the malware or ransomware may not be using the network at all, or may be using it in a stealthy or encrypted manner34. Furthermore, checking the network utilization does not address the root cause of the issue, which is the presence of malicious software on the laptop. Updating the antivirus software may not be sufficient to detect or remove the malware or ransomware, as some of them may evade or disable the antivirus software, or may be too new or unknown for the antivirus software to recognize34. Additionally, updating the antivirus software does not guarantee that the laptop will be scanned for malware or ransomware, as the user may need to initiate or schedule the scan manually.

• Question 676:

  A technician is working on a Windows 10 PC that has unwanted applications starting on boot. Which of the following tools should the technician use to disable applications on startup?

• Question 677:

  A company wants to reduce the negative ecological impacts of its business and has decided to hire an e- waste company to dispose of equipment.

  Which of the following should the e-waste company provide the business?

  A. Non-disclosure agreement
  B. Certification of destruction
  C. Low-level formatting
  D. Shredding/drilling
  B. Certification of destruction

  ---

  Explanation

  When disposing of e-waste, it is important to ensure that the data on the equipment is securely destroyed and that the disposal process complies with environmental regulations. Non-disclosure agreement: Relates to confidentiality, not

  disposal. Certification of destruction: The correct document verifying that the equipment has been disposed of in accordance with regulations and standards, ensuring data is irretrievably destroyed. Low-level formatting: A method to wipe data

  but does not guarantee compliance with e-waste disposal regulations.

  Shredding/drilling: Physical destruction methods that might be used, but certification of destruction is the documentation needed.

  CompTIA A+ Exam Objectives [220-1102] - 3.7: Explain the importance of physical security measures.

• Question 678:

• Question 679:

  A user received the following error upon visiting a banking website:

  The security presented by website was issued a different website' s address .

  A technician should instruct the user to:

  B. close out of the site and contact the bank.
  C. continue to the site and contact the bank.
  D. update the browser and contact the bank.
  A. clear the browser cache and contact the bank.

  ---

  Explanation

  The technician should instruct the user to clear the browser cache and contact the bank (option A). This error indicates that the website the user is visiting is not the correct website and is likely due to a cached version of the website being stored in the user's browser. Clearing the browser cache should remove any stored versions of the website and allow the user to access the correct website. The user should also contact the bank to confirm that they are visiting the correct website and to report the error.
