Question 9

Your Windows desktop system is running sluggishly. You have a magnetic hard drive and an M.2 drive. What could you do that might improve system performance? Choose two.

A) run optimize and defragment drive on the magnetic media drive
B) run disc cleanup on both drives
C) run optimize and defragment drive on the M.2 drive
D) run sfc

Answer 9

A, B
If you save many large files, and the hard drive gets to be under 10% free space, it’s performance can slow down dramatically. The disc cleanup utility will show you how much disk space is being taken up by temporary files, log files, the recycle bin, and other items that can easily be deleted. This could free up some disk space. Optimize and defragment Drive will help with mechanical hard drives, but not the solid state drives. In fact running it could damage a solid state drive. As you access and change files on a drive, the parts of the drive can end up scattered in different places. With a mechanical drive, retrieving the file will be faster if the files pieces are all next to each other on the drive. Defragmenting the drive rearranges it and puts each file scattered pieces together. System file Checker should be run if you’re having problems related to your system files. It will not free up space on your drive

Question 18

While booting up a Windows pc, you find it takes a long time at the welcome screen. The message “your roaming profile isn’t synchronized with the server…” appears. Which two of the following are true?

A) the user profile service detected a slow connection
B) a locally cashed profile was loaded
C) user profile service is not running
D) screen resolution is not compatible with the user’s profile

Answer 18

A, B

The windows user profile service detects when there is a slow link between the client computer and the domain controller. The service will then load the user’s profile from a copy that is cashed on the local machine. If the user has used a different machine since the last time they used the current one, then the profile changes will not be on the local machine.

Question 19

You just installed new external speakers on a Windows computer, and you have received an error message saying, “not enough USB controller resources” . What would most likely be causing this error? Choose two

A) the motherboard is damaged
B) USB devices are drawing more power than the limit
C) there are too many devices on a USB 3.0 Hub controller
D) the speaker drivers are conflicting with the USB hub controller drivers

Answer 19

B, C
USB ports provide limited power to the devices connected to them. If that power is exceeded one or more the devices attached to the controller may stop working and the error message, not enough USB controller resources, maybe generated. They also have a limited number of endpoints available on each port. Some devices use more endpoints than others and if the limit is exceeded, the same error message will be generated.

Question 20

Several mobile device users have reported that when they eat lunch in the garden next to the office building, they have limited internet connectivity. What is the most likely fix for this?

A) boost WAP signal strength
B) have all the users reboot their devices
C) reboot the WAP
D) have the users turn on Wi-Fi on each of their devices

Answer 20

Reboot the WAP

A limited connectivity error means that your device is able to connect to Wi-Fi but not to the internet. The fact that this is happening with several users in the same area likely means that it is a problem with the wireless access point, not an individual device. The users are getting a limited connectivity error, so they are connecting to the WAP but not getting an IP address from the DHCP server or router. Tricycling the WAP off and back on to resolve the issue. If that doesn’t work, troubleshoot the connection between the WAP and the router.

Question 21

A user on your network complains that they see a message for a long time that says, waiting for the user profile service, and their profile is very slow to load. What could be the problem?

A) there is a slow link between the domain controller and the client, but it was not correctly detected by the user profile service
B) the user has never logged into this computer before
C) Windows needs to be updated
D) the user entered an invalid password

Answer 21

A

This message happens when the user profile service incorrectly identifies the connection between the client and the server as a fast connection, when it is actually slow. These settings can be configured on the domain controller. If the user profile service detects a slow connection, it will load a cached profile from the local machine instead of the roaming profile on the server. If it is the first time the user has logged into a particular machine, then the profile will take longer to load because the entire profile is loaded not just the changes, but it would not generate this error message

Question 22

You are working on a Windows client and have received an error message saying, not enough USB controller resources. Which of the following is not a possible remedy for this situation?

A) plug a USB cable from a power block into one of the USB ports on the motherboard
B) purchase an external Hub or docking station that is separately powered and plug devices into it
C) move devices that don’t need USB 3 speed to USB 2.0 ports
D) disable the xhci mode option in the BIOS/UEFI settings

Answer 22

A
Plugging a USB cable from a power block into a port of the motherboard will not solve your problem, and it will likely destroy your motherboard. The first thing you should try is rearranging the devices that are using the USB ports. USB hubs have a limit as to how much power they can provide and the number of endpoints that each Port can support. A device may have multiple endpoints, and devices that are heavily involved in data transfer may use many more endpoints than other devices. Using an external Hub or docking station that is separately powered means that the port won’t be providing power to the devices, so this may result the issue. Disabling the xhci mode option in the bios, UEFI may help with the resource error but it will effectively turn off USB 3.0 and your hubs will behave like 2.0 ports

Question 23

You use an iPad and an iPhone at work. Which of the following represents the greatest threats to leaking personal files or data? Choose two

A) unauthorized root access
B) unintended Wi-Fi connections
C) unauthorized location tracking
D) High resource utilization

Answer 23

A, B
When authorized users access devices through unintended connections or unauthorized users access absconded devices such as with root access, they can access the data on the device. Every firm should have a policy for protecting data, encryption, and dealing with leaks when they occur.

Question 24

A smartphone user is concerned about their privacy and wants to ensure that others cannot hack into their phone and track down their location or access their personal data and pictures. Which of the following actions will provide them with some protection to help prevent this from happening? Choose two.

A) install an anti-malware app
B) install OS updates as soon as they are available
C) disable location services
D) enable sync with a cloud provider

Answer 24

A, B
Smartphones are susceptible to malware, just like any other computer device. Some malware can be configured to perform unauthorized location tracking. To help prevent this, always patch and update the OS as soon as updates are available and install anti-malware software. Some services such as match require that location services be enabled, but if the user chooses to location services can be disabled. Exactly how to do that depends on the device, but the option is most likely in the settings menu. Enabling sync with a cloud provider will make a backup of their data, but it does nothing to protect it from it being leaked

Question 25

A step in the malware removal best practices is to manually create a restore point and windows. what will the restore point do?

A) create a copy of the entire hard drive
B) create a copy of the user’s folder and system configuration data
C) create a copy of system configuration data
D) create a bootable media with copies of key system files

Answer 25

C
A restore point is a copy, or snapshot, of your system configuration at a given point in time. It is like a backup of your configuration but not your data. Snapshots are created within windows by clicking the search icon, typing create a restore point, and selecting it from the list of results. The system properties window opens. It should open on the system protection tab. If not, click the system protection tab, and near the bottom of the screen is a create button next to create a restore point right now for the drives that have system protection turned on. Clicking the create button begins the process of creating a restore point

Question 26

A user wants to use developer mode on their Android device to make some tweaks to the system. What setting will you tell them they should not leave on? Choose two

A) USB configuration
B) show touches
C) developer mode
D) debugging

Answer 26

C, D
If developer mode and the debugging feature are left on, then whenever the PC is connected to any computer, the Android device is essentially wide open, meaning that passwords, bank accounts, photos and so on are visible to anyone who accesses it. There are many features that can be manipulated and debugging mode, such as show touches, pointer location, transition animation scale and so on. Just ensure that developer mode and debugging are turned off when you are done with them

Question 27

You are attempting to share pictures with a friend using apples airdrop. You both have Wi-Fi and Bluetooth turned on. Neither of you is using your phone as a hotspot. They have you in their contacts list and their airdrop receiving setting is set to contacts only, yet you still can’t share files with them. Which of the following could be causing the problem? Choose two

A) you are set to receive from everyone
B) your contact card on their phone does not have your Apple ID email or phone number
C) you are not within Bluetooth range of each other
D) they turned off their hotspot

Answer 27

B, C
For airdrop to work, you both must have Wi-Fi and Bluetooth enabled. You need to be within Wi-Fi and Bluetooth range. If either party has a hotspot on, it must be turned off. If you are not in the receiver’s contact list and they have their airdrop set to receive from contacts only, then you will not be able to send them information. If you are in their contacts list, then your Apple ID email or your phone number must be in their contact card. If they change their airdrop receiving setting to everyone, then they can receive the file even if you are not in their contacts list
