IT Essentials 7.0 Practice Final Exam (Chapters 10-14) Test Online

Hint

On a hard disk, up to four primary partitions can be created. Alternatively, up to three primary partitions plus an extended partition can be created, and the extended partition can further be divided into multiple logical drives, if desired. Only one primary partition can be made the active partition at any time. It is the active partition that used by the operating system to boot a PC.

Hint

The primary partition that is marked active must carry the boot files for both the operating systems.In this case the data can be stored in the three logical drives created in the extended partition, leaving one extra primary drive for additional storage.

Hint

Typical causes of operating system problems are as follows:

• corrupted or missing system files
• incorrect device driver
• failed update or service pack installation
• corrupted registry
• failing of faulty hard drive
• incorrect password
• virus infection
• spyware

Hint

Rooting and jailbreaking mobile devices allows customization of the OS which enables user and app access to the root directory. In addition, rooting and jailbreaking may cause a device to not properly create or maintain sandboxing features. Both of these can create security risks to the device. The three incorrect options are all considered potential benefits of rooting and jailbreaking mobile devices

Hint

To help secure and protect the software and data on mobile devices, it is a best practice to do frequent backups. Another best practice is to ensure that all patches and updates are applied to software and applications. Patches and updates usually fix vulnerabilities as well as introduce new features.

Hint

Quick battery draining is most likely caused by roaming between call towers, a display that is set to a high level of brightness, or apps that are using too many resources. If an app is not compatible with the device, the device OS will freeze. If the operating system has encountered an error, the device will fail to respond.

Hint

Device tracking relies on GPS function. Turning off the GPS when not in use and disabling or removing apps that use the GPS function may prevent a device from being tracked.

Hint

The LCD screen consumes the most power on most mobile devices. The CPU, camera, and media player use power, but less extensively than the LCD screen does.

Hint

The Mac Disk Utility allows an administrator to configure automatic disk backups. The Deja Dup tool is a tool built into the Linux OS for backing up data. Disk Error-Checking is a Windows tool for checking the integrity of files and folders. The System Restore tool is a Windows tool for allowing an administrator to roll back the operating system to a previous configuration.

Hint

Two possible solutions to a reported missing or corrupt are to register the DLL file using the regsvr32 command or restart the computer in Safe Mode and run sfc/scannow. Windows Startup Repair is used solve Windows startup problems. Adjusting the program startup settings by using msconfig is applicable only to programs that start correctly. Drivers relate to hardware, not to programs.

Hint

If a computer locks without an error message, hardware or software could be the issue. Problems could include the following:

• The CPU or FSB are set incorrectly on the motherboard or in the BIOS.
• The computer is overheating.
• An update has corrupted the operating system.
• The RAM is failing or a RAM module is failing.
• The hard drive is failing.
• The power supply is failing.
• The computer has a virus.

Hint

The message “BOOTMGR is missing” could be a symptom of a missing or damaged BOOTMGR, a Boot Configuration Data file missing or damaged, a boot order not set correctly in BIOS, a corrupted MBR, or a failing hard drive. Because the OS cannot be located to start, the fix cannot be done using a regular command.

Hint

The bootrec command can be used to repair and troubleshoot MBR issues. The chkdsk command can be used to check the integrity of files and folders by scanning the hard disk surface for physical errors. The sfc command can be used to verify and replace important Windows system files.

Hint

Windows Credential Manager will only store passwords for websites that are visited using Explorer or Edge. Credentials created with other browsers must be managed from within the browser software.

Hint

By setting up an alternate IPv4 address on the laptop, the user will be able to move between a network with DHCP and another network that requires a static IPv4 address.

Hint

Call centers sometimes have different names for level one and level two technicians. Level one technicians might be known as level one analysts, dispatchers, or incident screeners. Level two technicians might be known as product specialists or technical-support personnel. The level two technician is usually more knowledgeable than the level one technician is about technology, or has been working for the company for a longer period of time. When a problem cannot be resolved within a predetermined amount of time, the level one technician prepares an escalated work order.

Hint

Level two technicians are primarily tasked with receiving and working on escalated work orders. Their tasks involve using remote access software to connect to the computer of a customer to perform maintenance and fixes.

Hint

A chain of custody requires accurate and thorough documentation to track the collected evidence.

Hint

It is not permissible to install, copy, or share digital content (including software, music, text, images, and video) in violation of copyright and software agreements or applicable laws. This is legally and ethically wrong.

Hint

When dealing with customers, a technician must show professionalism in all aspects. When explaining the solution to solve the problem, a technician should provide a simple step-by-step process of instructions. The technician should speak in plain terms and avoid the industry jargon.

Hint

When providing a solution to solve a problem, a technician should prepare to explain alternative ways that the technician can help the customer, if necessary, such as emailing information, faxing step-by-step instructions, or using remote control software to solve the problem.

Hint

The employee may have dropped off the laptop expecting repairs using the local user account. It is important to get permission from the customer before accessing other computer accounts, including the administrator account. If private information, such as usernames and passwords are being collected, it is important to keep them as confidential as possible.

Hint

Neither Windows XP nor Windows 7 32-bit can be upgraded to Windows 8.1 64-bit. A 32-bit operating system cannot be upgraded to a 64-bit operating system. A Windows XP system cannot be directly updated to Windows 8.1. In either of these cases, a clean installation must be performed.

Hint

Windows Home, Windows XP, and Windows Vista are not supported in the upgrade path to Windows 10. The 64-bit version of Windows 10 Enterprise cannot be downgraded to Windows 10.

Hint

There are many reasons that could cause a PC not to start, including hardware failure, MBR corruption, a hardware driver that was not installed properly, etc. One approach for PC troubleshooting is to boot the PC with a Windows 7 installation DVD and use the System Restore utility to restore the system. To access Safe Mode, we need to press the F8 key (not the F12 key). The other two options assume that the PC can start.

Hint

A 32-bit operating system can run on a x64 architecture, but it will not be able to use more than 4 GB of the system memory. A 64-bit OS includes features that provide additional security.

Hint

Master boot record (MBR) is the boot sector standard that supports a maximum primary partition of 2TB. MBR allows four primary partitions per drive. The globally unique identifier (GUID) partition table standard (GPT) can support enormous partitions with a theoretical maximum of 9.4ZB (9.4 x 10 to the 24th bytes). GPT supports a maximum of 128 primary partitions per drive.

Hint

When a base installation of an OS together together with applications is being performed, some computer and user specific information is included. This includes such items as SID, user accounts, and time zone. Before an image for deployment is finally created, the specific information must be removed. The Microsoft System Preparation (sysprep.exe) tool can be used for the task.

Hint

Botnets can be used to perform DDoS attacks, obtain data, or transmit malware to other devices on the network.

Hint

Data wiping software overwrites data multiple times. A degaussing wand or degaussing device uses magnetism to destroy data on a hard drive.

Hint

The User Accounts Windows Control Panel is used to create and manage local user accounts and configure passwords for each account. The Personalization Windows Control Panel is used to access the Screen Saver Settings window where the computer can be configured to display the logon screen if there is no use for a preconfigured amount of minutes.

Hint

After resolving a computer problem, the next step is to verify full functionality by ensuring that the OS is up to date and by testing the operation of the computer and the network that it is connected to. Documenting the issue and solution is the final step, whereas gathering information from the user and other sources are earlier steps in the troubleshooting process.

Hint

There are six steps in the troubleshooting process. 1. Identify the problem. 2. Establish a theory of probable cause. 3. Test the theory to determine cause. 4. Establish a plan of action to resolve the problem. 5. Verify full system functionality. 6. Document findings.

Hint

A proxy Trojan is a type of malware that uses one computer as a source device to launch attacks to other devices. Malware evolves quickly so it is important to obtain the most recent antimalware updates as a protective measure.

Hint

In addition to nontechnical users having a standard user account, it is also a best practice to make technical staff use a limited account. Then when an administrative task is needed, the technician uses the Run as Administrator option and provides the appropriate credentials of an account that has elevated credentials for the one task.

Hint

Users should have access to information on a need to know basis. When a user moves from job role to job role, the same concept applies.

Hint

The first thing the technician should do when addressing an “Invalid Boot Disk” error message is to ensure that the boot order in the UEFI/BIOS settings is set to drive that has the operating system installed as the first boot device.

Hint

The administrative command line tool regsvr32 in Windows 10 can be used to register and unregister .dll files and ActiveX controls in the Registry.

Hint

Use Disk Manage r to shrink the size of the existing partition. This creates unallocated space that can be used to create a new partition without loss of data on the existing partition.

Hint

The Windows Internet Protocol Version 4 (TCP/IPv4) Properties window includes an Alternate Configuration tab which allows an administrator to configure an alternative IP address for the PC to use if it is unable to contact a DHCP server.

Hint

Persistent data is data stored on an internal or external hard drive, or an optical drive. Data is preserved when the computer is turned off.

Hint

When a customer contacts a call center, the level one technician should always create a ticket and document the problem that the customer is experiencing. If the level one technician is unable to provide assistance, the technician should escalate the ticket to a level two technician.

Hint

Personally identifiable information (PII) is data that could be used to distinguish the identity of an individual, such as mother’s maiden name, social security number, and/or date of birth.
