Software Troubleshooting (1) Flashcards
Your network has 24 Windows 8.1 workstations. The office manager is concerned about spyware. What does Windows 8.1 come with, if anything, that will help thwart spyware?
Windows Firewall
Windows Defender
Windows Anti-malware
Windows Defender
There are many other forms of malware in addition to viruses. While a true antivirus program will scan for viruses, anti-malware programs are a superset of virus scanners and will look for more than just traditional viruses. One program included with Windows that falls into this category is Windows Defender, which is mainly a spyware detector (and incorporates Microsoft Security Essentials, or MSE, with it as of Windows 8 and later)
An iPhone user calls to report that his phone has no wireless connectivity. What is the first thing you should tell him to do?
Turn the phone off and back on.
Perform a reset to the factory default.
Check whether airplane mode is on.
Check whether airplane mode is on.
A common cause for lack of wireless connectivity is for a device to be in airplane mode. Make sure the device is not in that mode, and do a hard reboot if necessary
A Windows 7 workstation will not boot properly. Instead, there is an error message stating that there is no OS found. How do you fix this problem?
Boot to the installation DVD, open a command prompt, and type Startup Repair.
Boot to the installation DVD, open SFC, and choose Startup Repair.
Boot to the installation DVD, open System Recovery Options, and choose Startup Repair.
Boot to the installation DVD, open System Recovery Options, and choose Startup Repair.
If the operating system is missing, it could be due to a bad or corrupt boot sector on the hard drive, or the operating system may indeed be missing. If the hard drive is actually OK, then use the installation DVD (you may have to set the BIOS to use the DVD drive as your primary boot device) or the Windows Repair CD. In Windows 10, Windows 8/8.1, and Windows 7, go to System Recovery Options and choose Startup Repair
You have a user with an iPhone, and the device appears to be locked up. You need to tell him how to perform a hard reset. What do you tell him?
Press and hold the Sleep/Wake and Home buttons for at least 10 seconds until you see the Apple logo and then let go.
Press and hold the Sleep/Wake button until the red slider appears and then drag the slider to power off the device.
Use a paperclip or pen point to press and hold the indented reset button on the bottom of the phone until you see the Apple logo and then let go.
Press and hold the Sleep/Wake and Home buttons for at least 10 seconds until you see the Apple logo and then let go.
If the system is unresponsive, then a soft reset will not work. A hard reset is the next choice. With Apple’s iPhone, iPad, and iPod Touch, forcing a restart on the device is done by pressing and holding the Sleep/Wake and Home buttons for at least 10 seconds until you see the Apple logo
Your company purchases a custom database software package from an outside vendor. You install the client software on a Windows 10 workstation, and it crashes when you try to open it. You remove the software and reinstall it, but it still crashes when you open it. What should you do next?
Run an antivirus remediation on the workstation.
Contact the vendor to see whether an update or patch is available.
Delete and reinstall Windows.
Contact the vendor to see whether an update or patch is available.
When an application crashes, you want to isolate the cause of the crash—it could be a compatibility issue, hardware, or a host of other problems—and solve it. One step to take early on is to look for updates/patches/fixes to the application released by the vendor
On your MacBook Pro, you use the Safari browser to surf the Internet. Yesterday a friend borrowed your laptop. Today, when you try to browse the web, no matter what site URL you type in to the address bar, you are sent to a different website. What is most likely happening to your computer?
A practical joke by your friend
Browser redirection
Rogue antivirus
Browser redirection
This is a classic symptom of browser redirection. The perpetrator has one goal, which is to direct you to websites that he wants you to visit, regardless of what you actually want to see. Removing the redirector might be as simple as uninstalling an application (by dragging it to the Trash and emptying the Trash), or it might require full-scale virus (malware) mitigation
A Windows 8.1 workstation boots with this error message: “Security Center service cannot be started.” You try to start the service manually, but it still refuses to start. What should you do to try to fix the issue?
Use automated system recovery to fix the service.
Run REGSVR32 to fix the issue.
Run SFC /SCANNOW to fix the issue.
Run SFC /SCANNOW to fix the issue.
If the service refuses to start, even manually, it is possibly corrupt. (It is also possible that you have malware, but we’ll focus on it being corrupt first.) The system file checker (SFC) utility can fix the key system files needed to run this Windows service. If that doesn’t fix it, then follow the steps needed to mitigate malware, or reinstall Windows
A user has an iPhone and has forgotten the passcode. He has entered in the passcode several times, and it will not unlock. He turned the phone off and back on, and the passcode is still invalid. What can he do to unlock the phone?
Perform a reset to the factory default.
Crack the phone using a back door from Apple.
Perform a hard reset.
Perform a reset to the factory default.
Unfortunately, the only solution to a locked phone (or system lockout) is to perform a reset to factory specifications. That means that all the data on the phone is gone, unless it was synced with iTunes or iCloud (or the appropriate Android equivalent)
You want to display the contents of your iPad on a full-sized computer monitor. The monitor has a DVI connector. What do you need to do?
Plug the monitor in to the iPad’s DVI port.
Purchase a USB to DVI adapter.
Purchase a Lightning to DVI adapter.
Purchase a Lightning to DVI adapter.
iPads and iPhones are not large enough to have external DVI or other video ports. If you want to project to an external monitor, you need an adapter or an app that will allow you to broadcast to the monitor over Wi-Fi or Bluetooth
You are troubleshooting a Windows 10 workstation that could have malware on it. To follow the best practices for malware removal, what is the first step you should take?
Update the anti-malware software.
Enable system restore and create a restore point.
Identify malware symptoms.
Identify malware symptoms.
The best practices for malware removal is a seven-step process. Identify malware symptoms, quarantine the infected system, disable system restore (in Windows), remediate infected systems (including update anti-malware software and scan and remove the malware), schedule scans and run updates, enable system restore and create a restore point (in Windows), and educate the end user
Recently, users on your company network have been flooded with unrequested emails trying to sell them goods and services. Which solution will most likely resolve this issue?
Install antivirus on all client computers.
Install a spam filter on the email server.
Renew the invalid certificate on the email server.
Install a spam filter on the email server.
Spam is defined as any unwanted, unsolicited email, and not only can the sheer volume of it be irritating, it can often open the door to larger problems. While spam is not truly a virus or a hoax, it is one of the most annoying things with which an administrator must contend. Installing or enabling a spam filter on the email server is the best solution
Your network has several dozen mobile device users. Several of them have reported that there are areas within your office where network access is very slow. What can you use to test wireless access?
Wi-Fi analyzer
Cell tower analyzer
Data transmission analyzer
Wi-Fi analyzer
A Wi-Fi analyzer can be used on your network to see signal strength, channels used, and various other network metrics. Any company with a wireless network should have one for troubleshooting purposes
You just installed a new sound card in a Windows 7 workstation. Now, the computer has crashed and given you a blue screen of death. You turn the computer off. What should you try to resolve the issue?
Boot to the Windows installation CD and start the Recovery Console.
Boot to Safe Mode and uninstall the sound card driver.
Remove the sound card from the computer and reboot.
Boot to Safe Mode and uninstall the sound card driver.
The first rule with BSOD errors is to reboot. If the problem goes away, it could have just been a one-time problem. But since you just installed the sound card, it’s most likely the sound card driver that caused the issue. Reboot into Safe Mode and uninstall the driver. After you reboot again, look on the manufacturer’s site for an updated driver
An iPad user reports that when he is in a certain part of the building, his wireless connection intermittently drops. What are the two most likely causes of this? (Choose two.)
Poor wireless buffering in the iPad
Interference with the wireless signal
Weak signal strength from the wireless access point
Retracted Wi-Fi antenna on the iPad
Interference with the wireless signal
Weak signal strength from the wireless access point
There are a number of reasons intermittent wireless connections can occur, but the two most common are lack of a good signal and interference. Increasing the number of repeaters, or being closer to them, can address the lack of a good signal. Interference can be addressed by reducing the number of devices competing for the same channel or by moving away from walls or obstacles
A network user with an Android tablet wants to back up and synchronize her data with her phone. Which service should she use to perform these tasks?
Google Sync
Google Cloud
Android Sync
Google Sync
Because problems tend to happen no matter how careful you may be, it is important to back up devices and be able to restore from those backups after an incident. Google Sync is available for backups and synchronization of data between Android-based devices and PCs
