NEW QUESTION # 399
A branch office suspects a machine contains ransomware. Which of the following mitigation steps should a technician take first?
- A. Remediate the system.
- B. Educate the system user.
- C. Disable System Restore.
- D. Quarantine the system.
Answer: D
Explanation:
The first mitigation step that a technician should take when a machine is suspected to contain ransomware is to quarantine the system. This means isolating the infected machine from the network and other devices, to prevent the ransomware from spreading and encrypting more dat a. The technician can quarantine the system by disconnecting the network cable, turning off the wireless adapter, or using firewall rules to block the traffic from and to the machine12.
This step is more important than the other options because:
Disabling System Restore (A) is not a priority, as it will not stop the ransomware from running or spreading. System Restore is a feature that allows users to restore their system to a previous state, but it may not work if the ransomware has encrypted or deleted the restore points. Moreover, disabling System Restore may prevent the user from recovering some data or settings in the future13.
Remediating the system (B) is the ultimate goal, but it cannot be done before quarantining the system. Remediating the system means removing the ransomware, restoring the data, and fixing the vulnerabilities that allowed the attack. However, this process requires careful analysis, planning, and execution, and it may not be possible if the ransomware is still active and communicating with the attackers. Therefore, the technician should first isolate the system and then proceed with the remediation steps12.
Educating the system user © is a preventive measure, but it is not a mitigation step. Educating the system user means raising awareness and providing training on how to avoid ransomware attacks, such as by recognizing phishing emails, avoiding suspicious links or attachments, and updating and patching the system regularly. However, this step will not help if the system is already infected, and it may not be effective if the user is not willing or able to follow the best practices. Therefore, the technician should focus on resolving the current incident and then educate the user as part of the recovery plan14.

NEW QUESTION # 400
Which of the following does MFA provide?
- A. Security enhancement
- B. Public key infrastructure
- C. Digital signature
- D. Encryption
Answer: A
Explanation:
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.

- D. EFS
Answer: D
Explanation:
EFS (Encrypting File System) is a feature that allows a user to encrypt a single folder or file on a Windows PC. It uses a public key encryption system to protect the data from unauthorized access. FAT32 and exFAT are file system formats that do not support encryption. BitLocker is a feature that encrypts the entire drive, not a single folder or file.

A PC is taking a long time to boot. Which of the following operations would be best to do to resolve the issue at a minimal expense? (Select two).
* Installing additional RAM
- A. Ending the processes in the Task Manager
- B. Defragmenting the hard drive
- C. Running the Disk Cleanup utility
- D. Removing the applications from startup
- E. Installing a faster SSD
Answer: A,E
Explanation:
The correct answers are B. Removing the applications from startup and E. Defragmenting the hard drive.
These are the operations that would be best to do to resolve the issue of a slow boot at a minimal expense.
* Removing the applications from startup means disabling the programs that run automatically when the PC is turned on. This will reduce the load on the CPU and RAM and speed up the boot process1.
* Defragmenting the hard drive means rearranging the files on the disk so that they are stored in contiguous blocks. This will improve the disk performance and reduce the time it takes to read and write data2.

NEW QUESTION # 408
A large university wants to equip all classrooms with high-definition IP videoconferencing equipment. Which of the following would most likely be impacted in this situation?
- A. GPU
- B. PAN
- C. SAN
- D. LAN
Answer: D
Explanation:
LAN is the most likely option to be impacted in this situation. LAN stands for Local Area Network, and it is a network that connects devices within a limited area, such as a building or a campus. Installing high-definition IP videoconferencing equipment in all classrooms would require a high bandwidth and reliable LAN infrastructure to support the video and audio transmission. The LAN would also need to be configured with proper security, quality of service, and multicast protocols to ensure the optimal performance of the videoconferencing system. SAN, GPU, and PAN are not directly related to this scenario. SAN stands for Storage Area Network, and it is a network that provides access to consolidated storage devices. GPU stands for Graphics Processing Unit, and it is a hardware component that handles graphics rendering and computation. PAN stands for Personal Area Network, and it is a network that connects devices within a short range, such as Bluetooth or infrared. Reference:

NEW QUESTION # 409
Which of the following ensures proprietary information on a lost or stolen mobile device cannot be accessed while the device is offline?
- A. Location applications
- B. Mandatory screen locks
- C. Device data encryption
- D. Remote wipe
Answer: C
Explanation:
Device data encryption (Option D) ensures that even if the device is lost or stolen, its data cannot be accessed without proper credentials, even while offline. Encryption protects the data at rest, making it unreadable without the decryption key.
* Remote wipe (Option A) requires the device to be online to receive the wipe command.
* Mandatory screen locks (Option B) provide a layer of security but can be bypassed with physical access in some cases.
* Location applications (Option C) help track the device but don't protect data.
