The NTLDR loader file is a key component of the Windows XP boot process, and the system will not boot without it. The file can be retrieved from the Recovery Console, from SFC, or from bootable media (recovery DVD, repair disk, and so on)
An iPhone user is concerned about her privacy. She wants to ensure that others can’t hack into her phone and track her location without her knowing about it. Which of the following actions will provide her with the least amount of protection to help prevent this from happening?
Install an iPhone anti-malware app.
Update iOS as soon as updates or patches are available.
Disable Location Services.
Update iOS as soon as updates or patches are available.
iPhones 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 iOS as soon as updates are available and install anti-malware software. She can also disable Location Services in Settings➢ Privacy➢ Location Services
A user reports that the battery life on his iPhone is very short. It works for only about three hours before it needs to be recharged. What can you recommend he do to extend the battery life? (Choose two.)
Turn off unnecessary wireless connections.
Perform a reset to the factory defaults.
Set the screen to automatically dim.
Install an antivirus app.
Turn off unnecessary wireless connections.
Set the screen to automatically dim.
Tips for increasing battery life include keeping OS updates applied (they may include energy-saving patches), avoiding ambient temperatures that are too high or too low, letting the screen automatically dim, and turning off location-based services. You should also disconnect peripherals and quit applications not in use (Bluetooth, for example, uses power when enabled, even if you are not using it to connect to anything)
You have just purchased an Android mobile phone and are concerned about security threats. Which of the following statements is true?
There are no viruses for Android-based mobile phones.
Android-based phones come with an automatically enabled antivirus app.
You should download and install an antivirus app.
You should download and install an antivirus app.
Viruses do exist for Android; some industry estimates say that 90 percent of mobile-based viruses are targeted at Android OSs. Install an antivirus app and make sure it’s kept up-to-date, just as you would on a PC
A Windows 7 workstation has started exhibiting slow system performance. Where can you go in Windows to find tools to help you troubleshoot this problem?
Control Panel ➢ Performance Information And Tools
Control Panel ➢ System Tools
Control Panel ➢ Device Manager
Control Panel ➢ Performance Information And Tools
Windows 7 has a Performance Information And Tools applet in the Control Panel. Once in there, click Advanced Tools to see a list of different tools that can help you monitor system performance. A lot of these tools are also located elsewhere, such as Event Viewer, Task Manager, Performance Monitor, DEFRAG, and others
You have an Android mobile phone. When you go outside, the screen of your phone is dim, and you can’t see anything. What should you do to resolve the problem?
Power the device off and back on again.
Adjust the screen brightness settings.
Remove the screen protector.
Adjust the screen brightness settings.
Check the settings on the device to see whether it is possible to brighten the screen. You can also change how quickly the phone dims with inactivity, as perhaps it’s automatically dimming too quickly
Before you install a new antivirus program, a technician recommends that you manually create a restore point. What will the restore point do?
It will create a copy of the entire hard drive.
It will create a copy of system configuration data.
It will create a copy of the Users folder and system configuration data.
It will create a copy of system configuration data.
A restore point is a copy, or snapshot, of your system configuration at a given point in time. It’s like a backup of your configuration but not your data. Snapshots are created within Windows from the System Restore program. If Windows will not load, Safe Mode can be used to run rstrui.exe, which will open a version of System Restore so you can use a snapshot
An employee with an iPhone quit, and you are giving his iPhone to a new employee. What should you do to the phone before giving it to the new user?
Perform a soft reset.
Reset to the factory default.
Adjust configurations/settings.
Reset to the factory default.
When you need to get to a safe state—such as when you are disposing of a device or assigning it to a new user—you can reset it to the factory default settings. To do this, tap Settings and then General. Scroll down until you see the Reset option and choose it. Tap Erase All Content And Settings. At this point, the iPhone or iPad will ask you to confirm the reset, and when you tap OK, it will start the process
Your iPad is experiencing slow performance. What are the best two options to increase performance speed? (Choose two.)
Close open apps.
Perform a reset to the factory default.
Increase the RAM.
Perform a soft reset.
Close open apps.
Perform a soft reset.
Slow performance is often related to RAM. Look for any apps that are running and can be closed, or perform a soft reset to try to free up memory. Resetting to the factory default will delete all data on the device. You can’t upgrade the RAM in an iPad
You are working on a Windows workstation. When it boots up, it produces an error message that says “Missing Boot.ini” and does not boot any further. What is the purpose of the Boot.ini file?
In Windows XP and older, it identifies where the boot files are for the operating system.
In Windows 7 and newer, it identifies where the boot files are for the operating system.
In Windows XP and older, it starts the bootstrapping of the operating system.
In Windows XP and older, it identifies where the boot files are for the operating system.
Different versions of Windows use different files to identify what operating systems are installed and where their boot files can be found. With Windows XP and earlier versions (something you need to know only because NTLDR is an objective), the text file Boot.ini is used to identify the operating systems installed, their locations, and the boot options to use. Windows 10, Windows 8, and Windows 7 use the Windows Boot Configuration Data (BCD) file instead
A user with an iPhone reports that almost immediately after she touches her touch screen, the screen becomes dark and hard to read. What should she do to fix this?
Remove the screen protector.
Adjust the settings to keep it from dimming so quickly.
Power the device off and back on again.
Adjust the settings to keep it from dimming so quickly.
Light can quickly drain a battery on a mobile device, and thus most of them include the ability to dim the display both manually and automatically after a period of inactivity. While you normally want these actions, if the settings are incorrect, the screen can be too dim to work with. Check the settings on the device to see whether it possible to brighten the screen and/or keep it from automatically dimming within a short period of time
You have an Android tablet. The screen does not seem to accurately sense where you are touching on the touch pad. You reboot and the problem is still there. What should you do?
Replace the tablet.
Calibrate the screen.
Disable the gyroscope.
Calibrate the screen.
One option for an inaccurate touch screen is to clean the screen, but that doesn’t often solve the problem. A better solution is to calibrate the screen. Each mobile OS handles it differently, so check the manufacturer’s website for help
Windows 10 workstation will not load Windows. Which file in the boot process is responsible for switching the system from real mode to protected mode?
BOOTMGR
WINLOAD
WINRESUME
WINLOAD
In Windows 10/8/7, WINLOAD.EXE is responsible for switching the system from real mode (which lacks multitasking, memory protection, and those things that make Windows so great) to protected mode (which offers memory protection, multitasking, and so on) and enables paging. In Windows 10/8/7, WINLOAD.EXE replaces NTLDR from the Windows XP days
You are working on a Windows 8.1 workstation that has dual monitors. For some reason, everything on the secondary monitor is upside down. What is the easiest solution to this problem?
Turn the monitor over.
Right-click the desktop, choose Screen Resolution, and change the monitor orientation.
Right-click the desktop, choose Video, and change the monitor orientation.
Right-click the desktop, choose Screen Resolution, and change the monitor orientation.
The easiest thing to try is to change the monitor orientation. This can be done through Control Panel, but an easy way to get to the setting is to right-click the Windows Desktop, choose Screen Resolution, and then change the orientation
A Windows 7 workstation will boot only into Safe Mode. Even after multiple reboots, Windows will not load properly. Which tool should you use to scan for problems?
MSCONFIG
Event Viewer
Recovery Console
Recovery Console
At times, a system will become corrupted to the point where it will only boot into Safe Mode and not allow a normal boot. While a hardware issue can cause this, it can often be associated with a damaged/missing driver. To address the problem, boot into the Recovery Console and scan for problems. You can also choose to boot to the Last Known Good configuration or resort to the recovery DVD
