During a network outage, a technician discovers a new network switch that was not listed in the support documentation. The switch was installed during a recent change window when a new office was added to the environment. Which of the following would most likely prevent this type of mismatch after next month's change window?
Correct Answer:
B
This would ensure that the support documentation reflects the current state
of the network and prevents any confusion or mismatch during a network outage. Updating the network diagrams is also one of the best practices for network documentation, as
stated in the Official CompTIA A+ Core 2 Study Guide1. The other options are not as effective or feasible as option B. Performing annual network topology reviews is too infrequent and may not capture recent changes. Allowing network changes once per year is too restrictive and may not meet the business needs. Routinely backing up switch configuration files is important, but it does not help with identifying new switches or devices on the network.
A user's computer unexpectedly shut down immediately after the user plugged in a USB headset. Once the user turned the computer back on, everything was functioning properly, including the headset. Which of the following Microsoft tools would most likely be used to determine the root cause?
Correct Answer:
A
Event Viewer is a Microsoft tool that records and displays system events, errors, warnings, and information. Event Viewer can help troubleshoot and diagnose problems, such as unexpected shutdowns, by showing the details of what happened before, during, and after the incident. Event Viewer can also show the source of the event,
such as an application, a service, a driver, or a hardware device. By using Event Viewer, a technician can identify the root cause of the unexpected shutdown, such as a power failure, a thermal event, a driver conflict, or a malware infection.
A technician is upgrading the backup system for documents at a high-volume law firm. The current backup system can retain no more than three versions of full backups before failing. The law firm is not concerned about restore times but asks the technician to retain more versions when possible. Which of the following backup methods should the technician MOST likely implement?
Correct Answer:
C
Incremental backup is a backup method that only backs up the files that have changed since the last backup, whether it was a full or an incremental backup. Incremental backup can save storage space and bandwidth, as it does not copy the same files over and over again. Incremental backup can also retain more versions of backups, as it only stores the changes made to the files. However, incremental backup can have longer restore times, as it requires restoring the last full backup and all the subsequent incremental backups in order to recover the data. The law firm is not concerned about restore times but asks the technician to retain more versions when possible, so incremental backup would be a suitable choice for them.
A hard drive that previously contained PI I needs to be repurposed for a public access workstation. Which of the following data destruction methods should a technician use to ensure data is completely removed from the hard drive?
Correct Answer:
A
Shredding is a data destruction method that physically destroys the hard drive by cutting it into small pieces using a machine. Shredding ensures that data is completely removed from the hard drive and cannot be recovered by any means. Shredding is suitable for hard drives that contain PII (personally identifiable information),which is any information that can be used to identify, contact, or locate an individual. Degaussing, low-level formatting, and recycling are not data destruction methods that can guarantee complete data removal from a hard drive.
A user's company phone was stolen. Which of the following should a technician do next?
Correct Answer:
B
Remotely wiping the device is the best option to prevent unauthorized access to the company data stored on the phone. A low-level format, degaussing, or providing the GPS location of the device are not feasible or effective actions to take in this scenario.
