  E. Installer_Win10Enterprise.dmg
  D. Installer_x86.exe

  ---

  Explanation

  The 32-bit operating system can only run 32-bit applications, so the technician should execute the 32-bit installer. The "x86" in the file name refers to the 32-bit architecture. https://www.digitaltrends.com/computing/32-bit-vs-64-bit-operating-systems/

• Question 292:

  Which of the following would MOST likely be deployed to enhance physical security for a building? (Select TWO).

  A. Multifactor authentication
  B. Badge reader
  C. Personal identification number
  D. Firewall
  E. Motion sensor
  F. Soft token
  B. Badge reader
  E. Motion sensor

  ---

  Explanation

  Badge reader and motion sensor are devices that can be deployed to enhance physical security for a building. A badge reader is a device that scans and verifies an identification card or tag that grants access to authorized personnel only. A badge reader can help prevent unauthorized entry or intrusion into a building or a restricted area. A motion sensor is a device that detects movement and triggers an alarm or an action when motion is detected. A motion sensor can help deter or alert potential intruders or trespassers in a building or an area. Multifactor authentication is a method of verifying identity using two or more factors, such as something you know, something you have or something you are. Multifactor authentication is not a device that can be deployed to enhance physical security for a building but a technique that can be used to enhance logical security for systems or services. Personal identification number is a numeric code that can be used as part of authentication or access control. Personal identification number is not a device that can be deployed to enhance physical security for a building but an example of something you know factor in multifactor authentication. Firewall is a device or software that filters network traffic based on rules and policies. Firewall is not a device that can be deployed to enhance physical security for a building but a device that can be used to enhance network security for systems or services. Soft token is an application or software that generates one-time passwords or codes for authentication purposes. Soft token is not a device that can be deployed to enhance physical security for a building but an example of something you have factor in multifactor authentication.

  Users report that a network printer intermittently goes offline during the day.

  Which of the following commands should the technician use to confirm whether the printer has connectivity issues?

  A. ping
  B. netstat
  C. net
  D. nslookup
  A. ping

  ---

  Explanation

  To confirm whether a network printer has connectivity issues, the technician should use:

  ping: This command checks the connectivity to the printer by sending packets and measuring the response time. It helps determine if the printer is reachable on the network. netstat: Provides statistics and current network connections but

  does not directly confirm connectivity to a specific device.

  net: Used for network resources management but not specifically for checking connectivity. nslookup: Used for querying DNS to obtain domain name or IP address mapping, not for checking connectivity.

• Question 295:

  Which of the following filesystem formats would be the BEST choice to ensure read and write compatibility of USB flash drives across several generations of Microsoft operating systems?

  A. APFS
  B. ext4
  C. CDFS
  D. FAT32
  D. FAT32

  ---

  Explanation

  The best filesystem format to ensure read and write compatibility of USB flash drives across several generations of Microsoft operating systems is FAT32. FAT32 stands for File Allocation Table 32-bit and is a filesystem format that organizes and manages files and folders on storage devices using 32-bit clusters. FAT32 is compatible with most Microsoft operating systems since Windows 95 OSR, as well as other operating systems such as Linux and Mac OS X. FAT32 can support storage devices up to 2TB in size and files up to 4GB in size. APFS stands for Apple File System and is a filesystem format that organizes and manages files and folders on storage devices using encryption, snapshots and cloning features. APFS is compatible with Mac OS X 10.13 High Sierra and later versions but not with Microsoft operating systems natively. Ext4 stands for Fourth Extended File System and is a filesystem format that organizes and manages files and folders on storage devices using journaling, extents and delayed allocation features. Ext4 is compatible with Linux operating systems but not with Microsoft operating systems natively.

• Question 296:

  A technician is troubleshooting a Windows 10 PC that is unable to start the GUI. A new SSD and a new copy of Windows were recently installed on the PC. Which of the following is the most appropriate command to use to fix the issue?

  A. msconfig
  B. chkdsk
  C. sfc
  D. diskpart
  E. mstsc
  C. sfc

  ---

  Explanation

  The sfc command is a tool for scanning and repairing system files that are corrupted or missing on Windows operating systems12. System files are essential files that are required for the proper functioning of the operating system, such as the GUI, drivers, services, and applications. If system files are damaged or deleted, the operating system may fail to start or run properly, causing errors, crashes, or blue screens. The sfc command can be used to fix the issue of the PC that is unable to start the GUI, assuming that the problem is caused by corrupted or missing system files. The sfc command can be run from the command prompt, which can be accessed by booting the PC from the installation media, choosing the repair option, and selecting the command prompt option3. The sfc command can be used with different switches, such as /scannow, /verifyonly, /scanfile, or /offbootdir, depending on the situation and the desired action4. The most common switch is /scannow, which scans all the system files and repairs any problems that are found5. The syntax of the sfc command with the /scannow switch is: sfc /scannow The sfc command will then scan and repair the system files, and display the results on the screen. If the sfc command is able to fix the system files, the PC should be able to start the GUI normally after rebooting. If the sfc command is unable to fix the system files, the PC may need further troubleshooting or a clean installation of Windows.

• Question 297:

  Which of the following combinations meets the requirements for mobile device multifactor authentication?

  A. Password and PIN
  B. Password and swipe
  C. Fingerprint and password
  D. Swipe and PIN
  C. Fingerprint and password

  ---

  Explanation

  Multifactor authentication (MFA) requires the use of two or more verification factors to gain access to a resource such as an application, online account, or a VPN. The factors are categorized into something you know (like a password or PIN),

  something you have (like a security token or a smartphone), and something you are (like a biometric verification such as a fingerprint). Fingerprint and password: This combination meets the criteria for MFA as it uses two different categories

  of authentication factors: "something you are" (fingerprint) and "something you know" (password). This enhances security by combining two distinct methods of authentication.

  Other combinations mentioned:

  Password and PIN: Both of these factors fall under the same category of "something you know," and hence, do not constitute multifactor authentication. Password and swipe: Swiping a pattern is similar to a password in that it is something

  you know, so this does not qualify as multifactor authentication. Swipe and PIN: Again, both of these are "something you know" and do not qualify as multifactor authentication since they fall under the same category.

• Question 298:

  Which of the following authentication types is the most secure?

  A. WPA3
  B. WEP
  C. RADIUS
  D. TACACS+\
  E. WPS
  A. WPA3

• Question 299:

  A company is experiencing a DDoS attack. Several internal workstations are the source of the traffic. Which of the following types of infections are the workstations most likely experiencing? (Choose two.)

  A. Zombies
  B. Keylogger
  C. Adware
  D. Botnet
  E. Ransomware
  F. Spyware
  A. Zombies
  D. Botnet

  ---

  Explanation

  In a scenario where several internal workstations are the source of traffic in a DDoS attack, the workstations are most likely infected with one or both of the following:

  A. Zombies: Workstations infected with malware and controlled by an external entity to participate in a DDoS attack are often referred to as "zombies." These compromised machines become part of a botnet used for carrying out coordinated attacks.

  D. Botnet: A botnet is a network of compromised computers, including workstations, that have been infected with malicious software, turning them into "bots." These bots can be controlled remotely to carry out various malicious activities, including DDoS attacks.

  The other options (B. Keylogger,

  C. Adware,

  E. Ransomware, and

  F. Spyware) are types of malware or malicious software but are not directly associated with participating in DDoS attacks like zombies and botnets are.
