• Question 272:

  A user's mobile phone has become sluggish A systems administrator discovered several malicious applications on the device and reset the phone. The administrator installed MDM software. Which of the following should the administrator do to help secure the device against this threat in the future? (Select TWO).

  A. Prevent a device root
  B. Disable biometric authentication
  C. Require a PIN on the unlock screen
  D. Enable developer mode
  E. Block a third-party application installation
  F. Prevent GPS spoofing
  C. Require a PIN on the unlock screen
  E. Block a third-party application installation

  ---

  Explanation

  To help secure the device against this threat in the future, the administrator should require a PIN on the unlock screen and block a third-party application installation. Requiring a PIN on the unlock screen can help to prevent unauthorized access to the device, while blocking third-party application installation can help to prevent malicious applications from being installed on the device.

• Question 273:

  A user's corporate laptop with proprietary work information was stolen from a coffee shop. The user logged in to the laptop with a simple password, and no other security mechanisms were in place. Which of the following would MOST likely prevent the stored data from being recovered?

  A. Biometrics
  B. Full disk encryption
  C. Enforced strong system password
  D. Two-factor authentication
  B. Full disk encryption

  ---

  Explanation

  If your computer is ever stolen, or has an on-path attack attempt to steal data. Having entire drive encrypted through bitlocker will keep data unreadable for those who do not the proper tokens and passwords.

• Question 274:

  An employee has been using the same password for multiple applications and websites for the past several years. Which of the following would be best to prevent security issues?

  A. Configuring firewall settings
  B. Implementing expiration policies
  C. Defining complexity requirements
  D. Updating antivirus definitions
  B. Implementing expiration policies

  ---

  Explanation

  To prevent security issues related to an employee using the same password for multiple applications and websites, implementing expiration policies (B) is best. Password expiration policies require users to change their passwords at regular intervals, which helps to mitigate the risks associated with password reuse. Regularly changing passwords reduces the chances of unauthorized access from compromised credentials.

• Question 275:

  Which of the following is a consequence of end-of-lite operating systems?

  A. Operating systems void the hardware warranty.
  B. Operating systems cease to function.
  C. Operating systems no longer receive updates.
  D. Operating systems are unable to migrate data to the new operating system.
  C. Operating systems no longer receive updates.

  ---

  Explanation

  End-of-life operating systems are those which have reached the end of their life cycle and are no longer supported by the software developer. This means that the operating system will no longer receive updates, security patches, or other new features. This can leave users vulnerable to security threats, as the system will no longer be protected against the latest threats. Additionally, this can make it difficult to migrate data to a newer operating system, as the old system is no longer supported.

• Question 276:

  Which of the following is an advantage of using WPA2 instead of WPA3?

  A. Connection security
  B. Encryption key length
  C. Device compatibility
  D. Offline decryption resistance
  C. Device compatibility

  ---

  Explanation

  Device compatibility is an advantage of using WPA2 instead of WPA3. WPA2 is the previous version of the Wi-Fi Protected Access protocol, which provides security and encryption for wireless networks. WPA3 is the latest version, which offers improved security features, such as stronger encryption, enhanced protection against brute-force attacks, and easier configuration. However, WPA3 is not backward compatible with older devices that only support WPA2 or earlier protocols. Therefore, using WPA3 may limit the range of devices that can connect to the wireless network. Connection security, encryption key length, and offline decryption resistance are advantages of using WPA3 instead of WPA2.

  When a user reports that their workstation is behaving strangely after opening a suspicious email, the first step a technician should take is to run a virus scan on the computer. This is because opening a suspicious email is a common way for

  viruses and malware to infect a computer. Running a virus scan can help identify and remove any infections that may be causing the computer to behave strangely.

• Question 278:

  A customer, whose smartphone's screen was recently repaired, reports that the device has no internet access through Wi-Fi. The device shows that it is connected to Wi-Fi, has an address of 192.168.1.42. and has no subnet mask. Which of the following should the technician check next?

  A. Internal antenna connections
  B. Static IP settings
  C. Airplane mode
  D. Digitizer calibration
  A. Internal antenna connections

  ---

  Explanation

  Given that the smartphone's screen was recently repaired and now experiences issues with Wi-Fi connectivity, despite showing that it is connected to a network, the problem could be related to the internal antenna connections that might have been disturbed or disconnected during the repair process. Internal Antenna Connections: Smartphones use internal antennas for Wi-Fi and cellular connections. If these antennas are not properly connected, the device may show as connected to a Wi-Fi network but fail to transmit data effectively, resulting in no internet access. Checking static IP settings (B) would be relevant if the device were not obtaining an IP address at all, but the device does have an IP address. Airplane mode (C) would prevent the device from connecting to Wi-Fi networks entirely. Digitizer calibration (D) is related to the touchscreen functionality and would not affect Wi-Fi connectivity.

• Question 279:

  The calendar application on an employee's smartphone is experiencing frequent crashes, and the smartphone has become unresponsive. Which of the following should a technician do first to resolve the issue?

  A. Reinstall the application on the smartphone.
  B. Update the smartphone's OS.
  C. Reset the smartphone to factory settings.
  D. Reboot the smartphone.
  D. Reboot the smartphone.

  ---

  Explanation

  Rebooting the smartphone is the first and simplest step to resolve the issue of frequent crashes and unresponsiveness. Rebooting clears the memory, closes the background apps, and refreshes the system. It can also fix minor glitches and bugs that may cause the calendar app or the smartphone to malfunction12. The other options are either too drastic or unnecessary. Reinstalling the application may not solve the problem if the issue is with the smartphone itself. Updating the smartphone's OS may not be possible or helpful if the device is unresponsive or incompatible. Resetting the smartphone to factory settings will erase all the data and settings on the device, which should be the last resort.
