NEW QUESTION 1
A help desk technician determines a motherboard has failed. Which of the following is the most logical next step in the remediation process?

• A. Escalating the issue to Tier 2
• B. Verifying warranty status with the vendor
• C. Replacing the motherboard
• D. Purchasing another PC

Answer: B

Explanation:
Verifying warranty status with the vendor is the most logical next step in the remediation process after determining that a motherboard has failed. A warranty is a guarantee from the vendor that covers the repair or replacement of defective or faulty products within a specified period of time. Verifying warranty status with the vendor can help the technician determine if the motherboard is eligible for warranty service and what steps to take to obtain it. Escalating the issue to Tier 2, replacing the motherboard, and purchasing another PC are not the most logical next steps in the remediation process.

A technician needs administrator access on a Windows workstation to facilitate system changes without elevating permissions. Which of the following would best accomplish this task?

• A. Group Policy Editor
• B. Local Users and Groups
• C. Device Manager
• D. System Configuration

Answer: B

Explanation:
Local Users and Groups is the best option to accomplish this task. Local Users and Groups is a tool that allows managing the local user accounts and groups on a Windows workstation. The technician can use this tool to create a new user account with administrator privileges or add an existing user account to the Administrators group. This way, the technician can log in with the administrator account and make system changes without elevating permissions. Group Policy Editor, Device Manager, and System Configuration are not correct answers for this question. Group Policy Editor is a tool that allows configuring policies and settings for users and computers in a domain environment. Device Manager is a tool that allows managing the hardware devices and drivers on a Windows workstation. System Configuration is a tool that allows modifying the startup options and services on a Windows workstation. None of these tools can directly grant administrator access to a user account.

NEW QUESTION 7
Which of the following involves sending arbitrary characters in a web page request?

• A. SMS
• B. SSL
• C. XSS
• D. VPN

Answer: C

Explanation:
XSS stands for cross-site scripting, which is a web security vulnerability that allows an attacker to inject malicious code into a web page that is viewed by other users1. XSS involves sending arbitrary characters in a web page request, such as a query string, a form field, a cookie, or a header, that contain a malicious script. The web server does not validate or encode the input, and returns it as part of the web page response. The browserthen executes the script, which can perform various actions on behalf of the attacker, such as stealing cookies, session tokens, or other sensitive information, redirecting the user to a malicious site, or displaying fake content

• A. Delete the browser cookies and history.
• B. Reset all browser settings.
• C. Change the browser default search engine.
• D. Install a trusted browser.

Answer: D

Explanation:
The customer’s web browser is likely infected by a browser hijacker, which is
a type of malware that changes the browser’s settings and redirects the user to malicious websites. A browser hijacker can also steal the user’s personal data, display unwanted ads, and install more malware on the device. To remove a browser hijacker, the user should first uninstall the browser from the Control Panel, then scan the device with an antivirus or anti-malware program, and finally install a trusted browser from a legitimate source. Deleting the browser cookies and history, resetting the browser settings, or changing the browser default search engine may not be enough to get rid of the browser hijacker, as it may have embedded itself into the system or other browser components.

• B. Kerberos
• C. Preshared key
• D. WPA2/AES

Answer: D

Explanation:
WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.

NEW QUESTION 14
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.

Answer: D

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.

The technician can enable a Screensaver lock by choosing a screensaver from the drop-down menu, setting a wait time in minutes and checking the box that says “On resume, display logon screen”. This will lock the computer and require a password or PIN to log back in after the screensaver is activated. Ease of Access is an option in the Windows settings that allows users to adjust accessibility features and settings, such as narrator, magnifier, high contrast and keyboard shortcuts. Ease of Access is not related to enabling a Screensaver lock. Privacy is an option in the Windows settings that allows users to manage privacy and security settings, such aslocation, camera, microphone and app permissions. Privacy is not related to enabling a Screensaver lock. Update and Security is an option in the Windows settings that allows users to check and install updates, troubleshoot problems, backup files and restore system.

NEW QUESTION 17
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

Answer: C

Explanation:
Mobile device multifactor authentication (MFA) is a method of verifying a user’s identity by requiring two or more factors, such as something the user knows (e.g., password, PIN, security question), something the user has (e.g., smartphone, OTP app, security key), or something the user is (e.g., fingerprint, face, iris)12. The combination of fingerprint and password meets the requirements for mobile device MFA because it uses two different factors: something the user is (fingerprint) and something the user knows (password). The other combinations do not meet the requirements because they use only one factor: something the user knows (password or PIN) or something the user does (swipe).

• A. Cryptominer
• B. Phishing
• C. Ransomware
• D. Keylogger

Answer: C

Explanation:
Ransomware is malicious software that encrypts files on a computer, making them inaccessible until a ransom is paid.
