  ---

  Explanation

  EAP-TLS is a method of authentication that uses certificates to establish a secure tunnel between the client and the server. The certificates have a validity period and must be renewed before they expire. If the user has been on an extended leave and has not logged in to the computer in several months, it is possible that the certificate on the client or the server has expired and needs to be renewed. The other options are not directly related to EAP-TLS authentication or 802.1X network access.

  Explanation

  Windows is the operating system that typically requires the most computing resources from the host computer, compared to the other options. Computing resources include hardware components such as CPU, RAM, disk space, graphics card, and network adapter. The minimum system requirements for an operating system indicate the minimum amount of computing resources needed to install and run the operating system on a computer. The higher the minimum system requirements, the more computing resources the operating system consumes. According to the web search results, the minimum system requirements for Windows 10 and Windows 11 are as follows12: CPU: 1 GHz or faster with two or more cores (Windows 10); 1 GHz or faster with two or more cores on a compatible 64-bit processor (Windows 11) RAM: 1 GB for 32-bit or 2 GB for 64-bit (Windows 10); 4 GB (Windows 11) Disk space: 16 GB for 32-bit or 32 GB for 64-bit (Windows 10); 64 GB (Windows 11) Graphics card: DirectX 9 or later with WDDM 1.0 driver (Windows 10); DirectX 12 compatible with WDDM 2.0 driver (Windows 11) Network adapter: Ethernet or Wi-Fi (Windows 10); Ethernet or Wi-Fi that supports 5 GHz (Windows 11) The minimum system requirements for macOS Ventura are as follows: CPU: Intel Core i3 or higher, or Apple M1 chip RAM: 4 GB Disk space: 35.5 GB Graphics card: Metal-capable Network adapter: Ethernet or Wi-Fi The minimum system requirements for Chrome OS are as follows: CPU: Intel Celeron or higher RAM: 2 GB Disk space: 16 GB Graphics card: Integrated Network adapter: Ethernet or Wi-Fi The minimum system requirements for Android are as follows: CPU: 1 GHz or higher RAM: 512 MB Disk space: 8 GB Graphics card: OpenGL ES 2.0 Network adapter: Ethernet or Wi-Fi The minimum system requirements for Linux vary depending on the distribution, but a common example is Ubuntu, which has the following minimum system requirements: CPU: 2 GHz dual core processor or better RAM: 4 GB Disk space: 25 GB Graphics card: 1024 x 768 screen resolution Network adapter: Ethernet or Wi-Fi Based on the comparison of the minimum system requirements, Windows has the highest requirements for CPU, RAM, disk space, and graphics card, while Chrome OS and Android have the lowest requirements. macOS and Linux have moderate requirements, depending on the hardware and software configuration. Therefore, Windows is the operating system that typically requires the most computing resources from the host computer.

• Question 166:

  Which of the following provide the BEST way to secure physical access to a data cento server room? (Select TWO).

  A. Biometric lock
  B. Badge reader
  C. USB token
  D. Video surveillance
  E. Locking rack
  F. Access control vestibule
  A. Biometric lock

  ---

  Explanation

  A biometric lock requires an authorized user to provide a unique biometric identifier, such as a fingerprint, in order to gain access to the server room. A badge reader requires an authorized user to swipe an access card in order to gain access. Both of these methods ensure that only authorized personnel are able to access the server room. Additionally, video surveillance and access control vestibules can be used to further secure the server room. Finally, a locking rack can be used to physically secure the servers, so that they cannot be accessed without the appropriate key.

It can lead the victim to a phishing site where the cybercriminal can lure the target into sharing their private data. It is literally called ''USB baiting''

• Question 170:

  A user's antivirus software reports an infection that it is unable to remove. Which of the following is the most appropriate way to remediate the issue?

  A. Disable System Restore.
  B. Utilize a Linux live disc.
  C. Quarantine the infected system.
  D. Update the anti-malware.
  C. Quarantine the infected system.

  ---

  Explanation

  Quarantining the infected system is the most appropriate way to remediate the issue of an infection that the antivirus software cannot remove. Quarantining means isolating the system from the network and other devices to prevent the infection from spreading or causing further damage. Quarantining also allows the technician to perform further analysis and removal of the infection without risking the security of other systems or data. Some of the steps involved in quarantining an infected system are: Disconnect the system from the internet and any local network connections, such as Wi-Fi, Ethernet, Bluetooth, or USB. Disable any file-sharing or remote access services on the system, such as Windows File Sharing, Remote Desktop, or TeamViewer. Use a separate device to download and update the antivirus software and any other tools that may be needed to remove the infection, such as malware scanners, rootkit removers, or bootable rescue disks. Transfer the updated antivirus software and tools to the infected system using a removable media, such as a CD, DVD, or USB flash drive. Scan the removable media for any infections before and after using it on the infected system. Run the antivirus software and tools on the infected system and follow the instructions to delete or quarantine the infection. If the infection is persistent or complex, it may require booting the system from a rescue disk or using a Linux live disc to access and clean the system files. After the infection is removed, restore the system to a previous clean state using System Restore, backup, or recovery partition. Scan the system again to ensure that it is clean and secure. Reconnect the system to the network and update the system and the antivirus software.
