CompTIA A+ Certification Exam: Core 2 Sample Questions (Q71-Q76):

NEW QUESTION # 71
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. 32- vs. 64-bit architecture
  • B. Storage requirements
  • C. Quality of service
  • D. OS compatibility

Answer: C

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.


NEW QUESTION # 72
When a user is in the office, the user's mobile phone loads applications and web browses very slowly on a cellular connection. Which of the following is the best way to fix this issue?

  • A. Update all applications on the phone.
  • B. Connect to the company's Wi-Fi network.
  • C. Change the settings on the phone to connect to a different cellular tower.
  • D. Install a cellular repeater at the office for this user.

Answer: B

Explanation:
The best way to fix the issue of slow cellular connection in the office is to connect to the company's Wi-Fi network. This will allow the user's mobile phone to access the internet through a faster and more reliable wireless network, instead of relying on the cellular network. Connecting to the Wi-Fi network will also save the user's data usage and battery life.
Some of the factors that can affect the cellular connection speed are the distance from the cell tower, the obstructions between the phone and the tower, the network congestion, the network technology, and the features of the phone12. In the office, the user may experience a weak or unstable cellular signal due to the building structure, the location, or the interference from other devices. Therefore, switching to the Wi-Fi network can improve the performance of the phone's applications and web browsing.

NEW QUESTION # 73
A technician is updating the OS on a number of Windows workstations. After successfully updating several workstations, the technician receives an error indicating that the upgrade takes more space than is available on one of the PCs. Which of the following should the technician do to proceed with the upgrade? (Select two).

  • A. Uninstall unused desktop applications.
  • B. Delete unnecessary files.
  • C. Restore the system files.
  • D. Add additional memory.
  • E. Update the driver software.
  • F. Unplug the extra hardware.

Answer: A,B

Explanation:
To free up space for the upgrade, the technician should delete unnecessary files and uninstall unused desktop applications. These actions will clear storage, making room for the update. Additional memory would not solve a storage issue, and driver updates are not relevant to the storage space problem.

NEW QUESTION # 74
A technician successfully removed malicious software from an infected computer after running updates and scheduled scans to mitigate future risks. Which of the following should the technician do next?

  • A. Create a system restore point.
  • B. Educate the end user on best practices for security.
  • C. Quarantine the host in the antivirus system.
  • D. Investigate how the system was infected with malware.

Answer: B

Explanation:
Educating the end user on best practices for security is the next step that the technician should take after successfully removing malicious software from an infected computer. Educating the end user on best practices for security is an important part of preventing future infections and mitigating risks. The technician should explain to the end user how to avoid common sources of malware, such as phishing emails, malicious websites, or removable media. The technician should also advise the end user to use strong passwords, update software regularly, enable antivirus and firewall protection, and backup data frequently. Educating the end user on best practices for security can help the end user become more aware and responsible for their own security and reduce the likelihood of recurrence of malware infections. Quarantining the host in the antivirus system, investigating how the system was infected with malware, and creating a system restore point are not the next steps that the technician should take after successfully removing malicious software from an infected computer. Quarantining the host in the antivirus system is a step that the technician should take before removing malicious software from an infected computer. Quarantining the host in the antivirus system means isolating the infected computer from the network or other devices to prevent the spread of malware.
Investigating how the system was infected with malware is a step that the technician should take during or after removing malicious software from an infected computer. Investigating how the system was infected with malware means identifying the source, type, and impact of malware on the system and documenting the findings and actions taken. Creating a system restore point is a step that the technician should take before removing malicious software from an infected computer. Creating a system restore point means saving a snapshot of the system's configuration and settings at a certain point in time, which can be used to restore the system in case of failure or corruption.

NEW QUESTION # 75
A technician is editing the hosts file on a few PCs in order to block certain domains. Which of the following would the technician need to execute after editing the hosts file?

  • A. Reset the network adapter.
  • B. Clear the browser cache.
  • C. Add a new network adapter.
  • D. Enable promiscuous mode.

Answer: A

Explanation:
Explanation
Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.
