When a user starts their desktop computer, the Windows splash screen is shown with a rotating circle, but the login screen is never displayed. A technician researches the issue and finds the computer was just updated to the latest set of Windows patches. Which of the following would be the NEXT step the technician should follow to help solve this issue?

• A. Restart the computer

• B. Perform a Startup Repair

• C. Start in VGA mode

• D. Rebuild the user's profile

Answer explanation

B. Perform a Startup Repair The Windows Startup Repair is an automated feature that will examine each phase of the startup process and reconfigure any invalid or incorrect settings. This is a common repair to use when the startup process is not working properly after an application or operating system update. The incorrect answers: A. Restart the computer It's most likely the Windows patches caused this login problem, so restarting the system would still cause the system to exhibit the same issue. C. Start in VGA mode If Windows was displaying a completely black screen instead of the login prompt, then starting in VGA mode may be useful. In this example, the Windows splash screen and rotating circle are visible on the screen. D. Rebuild the user's profile A bad user profile might cause the desktop to appear differently than normal and user files may not be visible from the File Explorer. In this example, the desktop and other user files were not accessible because the login prompt did not appear.

A desktop technician is moving hard drives from one set of training room computers to another. Which of the following would allow the drives to be used in the new computers but prevent any of the existing data from being recovered?

• A. Shredder

• B. Quick format

• C. Drill

• D. Standard format

Answer explanation

D. Standard format The Windows standard format will overwrite each sector of the drive and prevent any recovery tools from restoring any of the previous data. The incorrect answers: A. Shredder A shredder will physically cut the drive into small pieces. This certainly prevents the recovery of the data, but it also causes the drive to be permanently damaged and unusable. B. Quick format A Windows quick format overwrites the file system table and marks all of the data on the drive as "deleted." None of the sectors are overwritten, and recovery software can often restore the remaining data. C. Drill A drill will ensure that the data cannot be recovered, but it physically damages the drive so that it cannot be used by others.

A technician is troubleshooting a problem with user’s laptop and very high utilization, even with no activity on the screen or user input to the operating system. Task Manager shows the CPU is operating at 100% utilization, memory utilization is slightly elevated, and there is a large amount of outbound network communication. Which of the following would be the MOST likely reason for these issues?

• A. System RAM is faulty

• B. User has not properly authenticated

• C. Laptop is part of a DDoS attack

• D. Network adapter is faulty

Answer explanation

C. Laptop is part of a DDoS attack High CPU utilization, memory use, and network traffic with no user intervention indicates a possible malware infection and participation in a DDoS (Distributed Denial of Service) attack. Of the available options, this would be the most likely reason for these symptoms. The incorrect answers: A. System RAM is faulty Bad system memory usually causes the system to fail with a Windows stop error or to simply hang. Bad system RAM would not cause the CPU, memory, or network issues on this user's laptop. B. User has not properly authenticated A user who has not authenticated would be expected to have less CPU, memory, and network resource usage. It would not be common for an authentication issue to cause this resource activity. D. Network adapter is faulty A bad network adapter might cause errors to accumulate on the network link, but it would not commonly cause an increase in CPU and memory usage.

A user's smartphone app shows a splash screen but disappears after a few seconds. Which of the following would be the BEST way for the a technician use to view logs and memory statistics for the app?

• A. Developer mode

• B. Cloud storage

• C. Jailbreaking

• D. Application spoofing

Answer explanation

A. Developer mode Developer mode enables features commonly used by developers but can be used by anyone to help with troubleshooting and information gathering. The incorrect answers: B. Cloud storage Cloud storage is useful for backing up a mobile device, but it doesn't provide any additional statistics or troubleshooting information. C. Jailbreaking Jailbreaking is an unsupported method to gain direct access to the smartphone operating system, and it's a direct violation of the software's end user license agreement. Jailbreaking should never be used on a corporate smartphone. D. Application spoofing An application that looks legitimate but is instead malicious is an application spoofing attack. Application spoofing does not provide any additional troubleshooting tools. More information: 220-1102, Objective 3.5 Troubleshooting Mobile Device Security https://professormesser.link/1102030501

A company has created an internal process to ensure that all PII is encrypted. Which of the following would be the MOST likely reason for adding this additional security?

• A. Helps prevent identity theft

• B. Improves application performance

• C. Allows customer data to be easily deleted

• D. Uses less storage space

Answer explanation

A. Helps prevent identity theft PII (Personally Identifiable Information) is any information that can identify an individual. This information can be an address, phone number, or date of birth. Encrypting PII will help prevent the unintended release of personal data and would assist with preventing identity theft. The incorrect answers: B. Improves application performance The process of encrypting and decrypting data adds more overhead to the data storage process. Although application performance may not become any worse, the encryption process would not commonly improve performance. C. Allows customer data to be easily deleted The removal of customer data is not made easier through the use of encryption. Although it's useful to have processes to remove user information, that process is managed in conjunction with the encryption and decryption process. D. Uses less storage space The encryption process would not commonly be used as a way to decrease the use of storage space. If encryption and decryption is being used, there is most likely a security focus for implementing such a process.

A system administrator is installing a file server into the corporate data center. Which of the following would be the BEST way to improve security of the file sharing service? (Select TWO)

• A. Enable a BIOS user password

• B. Connect the server to a wireless network

• D. Disable guest account

• E. Enable file storage quotas

• F. Enable password complexity

Answer explanation

: D. Disable guest account, and F. Enable password complexity The only available options associated with server security are those to disable guest accounts and increase the complexity of the passwords. Guest accounts can be exploited, and passwords that are easy to guess or set to defaults can be discovered by an attacker. The incorrect answers: A. Enable a BIOS user password Enabling a password during the startup process does not protect the server once it has started. B. Connect the server to a wireless network Wireless networks do not provide any additional application security. Connecting to a wireless network would not improve the security posture of the server. C. Limit the number of concurrent connections Limiting concurrent connections would restrict the throughput of the service and would not provide any security enhancements. E. Enable file storage quotas Storage quotas would conserve storage space on the server, but they would not provide any additional security enhancements.
