CompTIA A+ Certification Exam: Core 2 Sample Questions (Q217-Q222):

NEW QUESTION # 217
A technician has been unable to remediate a persistent malware infection on a user's workstation. After the technician reinstalled the OS. the malware infection returned later that day. Which of the following is the most likely source?

  • A. Spyware
  • B. Rootkit
  • C. Trojan
  • D. Boot sector virus

Answer: D

Explanation:
A boot sector virus infects the master boot record (MBR) of a hard drive, the sector that contains information required to start the operating system after the computer is turned on. This type of virus is particularly insidious because it loads into memory immediately upon booting and before most antivirus programs start.
This makes it possible for the virus to evade detection and removal, and can easily reinfect a system even after the operating system is reinstalled if the boot sector is not cleaned.
* Boot sector virus:Given that the malware infection returned after the OS reinstallation, it's likely that the virus was not removed from the boot sector during the reinstallation process. Reinstalling the OS
* without cleaning the boot sector won't remove the infection, allowing the virus to continue to affect the system.
Other options:
* Trojan:A Trojan is a type of malware that disguises itself as legitimate software. While Trojans can be persistent, the reinstallation of the OS should remove any Trojans unless they are reintroduced after installation.
* Spyware:Spyware is designed to gather information about a person or organization without their knowledge. Like Trojans, spyware should be removed with an OS reinstallation unless it is reintroduced in some way.
* Rootkit:Rootkits are designed to enable continued privileged access to a computer while actively hiding their presence. While a rootkit could potentially survive an OS reinstall if it infects the firmware or certain areas outside the OS, the scenario described points more specifically to a boot sector virus, especially considering the immediate return of the infection after OS reinstallation.


NEW QUESTION # 218
A change advisory board did not approve a requested change due to the lack of alternative actions if implementation failed. Which of the following should be updated before requesting approval again?

  • A. End user acceptance
  • B. Scope of change
  • C. Rollback plan
  • D. Risk level

Answer: C

Explanation:
The rollback plan should be updated before requesting approval again. A rollback plan is a plan for undoing a change if it causes problems, and it is an important part of any change management process. If the change advisory board did not approve the requested change due to the lack of alternative actions if implementation failed, then updating the rollback plan would be the best way to address this concern.


NEW QUESTION # 219
A technician is installing new network equipment in a SOHO and wants to ensure the equipment is secured against external threats on the Internet. Which of the following actions should the technician do FIRST?

  • A. Change the default administrative password.
  • B. Install the latest operating system and patches
  • C. Ensure all devices are from the same manufacturer.
  • D. Lock all devices in a closet.

Answer: A

Explanation:
Explanation
The technician should change the default administrative password FIRST to ensure the network equipment is secured against external threats on the Internet. Changing the default administrative password is a basic security measure that can help prevent unauthorized access to the network equipment. Locking all devices in a closet is a physical security measure that can help prevent theft or damage to the devices, but it does not address external threats on the Internet. Ensuring all devices are from the same manufacturer is not a security measure and does not address external threats on the Internet. Installing the latest operating system and patches is important for maintaining the security of the network equipment, but it is not the first action the technician should take1


NEW QUESTION # 220
A customer has a USB-only printer attached to a computer. A technician is configuring an arrangement that allows other computers on the network to use the printer. In which of the following locations on the customer's desktop should the technician make this configuration?

  • A. Printer Properties/Ports tab
  • B. Printing Preferences/Advanced tab
  • C. Printer Properties/Security tab
  • D. Printer Properties/Sharing tab

Answer: D

Explanation:
The correct answer is B. Printer Properties/Sharing tab. This is the location where the technician can enable printer sharing and assign a share name for the USB printer. This will allow other computers on the network to access the printer by using the share name or the IP address of the computer that has the printer attached1.

NEW QUESTION # 221
A company recently outsourced its night-shift cleaning service. A technician is concerned about having unsupervised contractors in the building. Which of the following security measures can be used to prevent the computers from being accessed? (Select two).

  • A. Restricting user permissions
  • B. Enabling a screen lock
  • C. Restricting log-in times
  • D. Disabling AutoRun
  • E. Implementing data-at-rest encryption
  • F. Disabling local administrator accounts

Answer: B,C

Explanation:
The correct answers are D. Restricting log-in times and E. Enabling a screen lock. These are the security measures that can be used to prevent the computers from being accessed by unsupervised contractors in the building.
Restricting log-in times means setting a policy that allows users to log in only during certain hours, such as the regular working hours of the company. This will prevent unauthorized access by contractors who work at night1.
Enabling a screen lock means setting a policy that requires users to enter a password or a PIN to unlock their screens after a period of inactivity. This will prevent unauthorized access by contractors who might try to use the computers when the users are away2.
