3.

You have a customer that has installed an updated device driver for their sound card and now it is not functioning properly. How can you roll back the driver

  • Go to Device manager and click Roll Back Driver.

  • Go to Device Manager, click on the Device and Roll Back Driver.

  • Go to Device Manager. Right-click on the Device. Click Properties. Click on the Driver tab and Click Roll Back Driver.

  • Restart the computer in Last known good configuration Mode.

Explanation

Correct Answer C. Go to Device Manager. Right-click on the Device. Click Properties. Click on the Driver tab and Click Roll Back Driver.

Explanation

To roll back a device driver, you must access the device's properties in the Device Manager, where you can find a "Driver" tab. In this tab, there is an option to roll back to a previous driver version. This is the correct procedure for rolling back a device driver.

Why other options are wrong

A. Go to Device manager and click Roll Back Driver.

This option is incomplete and lacks the necessary steps to properly access the device and its properties in the Device Manager.

B. Go to Device Manager, click on the Device and Roll Back Driver.

Clicking on the device is only part of the process; you also need to access the "Properties" section, which is missed in this option.

D. Restart the computer in Last known good configuration Mode.

This option may restore the system to a previous state, but it does not specifically target rolling back a driver update. It is more of a general troubleshooting step for system-related issues.


4.

When creating a text file using the built-in open() function with 'a' mode, what will occur if a file is written to a directory which contains a file having the same name

  • The file is appended to, with the original contents saved.

  • An OS Error.

  • The file is overwritten.

  • A duplicate is created with a modified filename.

Explanation

Correct Answer A. The file is appended to, with the original contents saved. 

Explanation

In Python, when using the 'a' mode (append mode) to open a file with the open() function, it will not overwrite the file. Instead, it will open the file for writing, and any new content will be added to the end of the file, preserving the original content. If the file doesn't exist, it will be created.

Why other options are wrong

B. An OS Error.

Using the 'a' mode will not result in an OS error unless the file is inaccessible or the user doesn't have write permissions. In general, the append mode will not generate an error in normal conditions, even if the file already exists.

C. The file is overwritten.

This is incorrect because the 'a' mode explicitly avoids overwriting the file. Overwriting a file would happen in 'w' mode (write mode) or 'x' mode (exclusive creation), not in append mode.

D. A duplicate is created with a modified filename.

Append mode does not create a duplicate file. It will modify the existing file, adding content to the end. If a file with the same name exists, it will be appended to, not duplicated or renamed.


5.

Cloud file storage services, like Dropbox and Box, allow people to move to the cloud for some of their storage needs. These services include ________ with their desktop versions, so that you can easily have the same version of every file in multiple places (desktop, laptop, online)

  • Hypervisors

  • On-demand apps

  • Synchronization apps

  • Resource pooling

Explanation

Correct Answer C. Synchronization apps

Explanation

Synchronization apps ensure that files stored in a cloud-based service are kept up to date across multiple devices. When a user edits or adds a file on one device, the synchronization app automatically updates the cloud copy and then reflects those changes on all other connected devices. This allows for consistent access to the most recent file version regardless of location or device.

Why other options are wrong

A. Hypervisors

Hypervisors are used in virtualization to allow multiple operating systems to run on a single physical machine. They are not related to file synchronization or cloud storage. Including this as an option is misleading because hypervisors serve an entirely different purpose in IT infrastructure.

B. On-demand apps

While on-demand apps refer to applications that are accessed as needed (often via the cloud), they are not specific to keeping file versions synchronized across devices. On-demand computing refers more to the availability of services rather than maintaining file consistency across platforms.

D. Resource pooling

Resource pooling refers to a cloud computing concept where multiple users share a pool of resources (like storage, processing power, etc.). While it’s relevant to cloud infrastructure, it does not directly relate to the functionality that keeps file versions consistent across devices.

When selecting a processor to match system needs, what features should you NOT consider

  • Reviews of processors, including benchmarks and comparisons to other processors

  • Processor's ability to multitask, the number of cores, and multithreading abilities and which programs can make use of the abilities

  • Balancing the performance and power of the CPU with the entire system, including graphics adaptors and hard drives

  • Finding the latest and most powerful processor available no matter the cost

Explanation

Correct Answer D. Finding the latest and most powerful processor available no matter the cost

Explanation

While the latest and most powerful processor might sound appealing, it is not always the best option if it exceeds your budget or doesn’t match your system needs. Selecting the right processor involves balancing performance with the overall system requirements, such as memory, storage, and graphics. Often, a less powerful processor may be more cost-effective and still fulfill the tasks required.

Why other options are wrong

A. Reviews of processors, including benchmarks and comparisons to other processors

This is crucial when selecting a processor, as it helps to compare various processors' performance, power consumption, and overall efficiency. Reviews and benchmarks provide valuable insights into which processor will meet your specific needs.

B. Processor's ability to multitask, the number of cores, and multithreading abilities and which programs can make use of the abilities

These are essential features to consider because they affect the performance of multitasking and specialized tasks. For example, a processor with more cores and multithreading capabilities can significantly improve performance for programs that support such features.

C. Balancing the performance and power of the CPU with the entire system, including graphics adaptors and hard drives

This is important because the processor should be chosen based on the entire system's requirements, not in isolation. Balancing performance with the rest of the system ensures the best overall user experience and system efficiency.


7.

Which of the following positions have a computer knowledgebase at their disposal to help them investigate the technology problems at hand

  • Database Administrator

  • Trainer

  • CIO

  • Help Desk Analyst

Explanation

Correct Answer D. Help Desk Analyst

Explanation

A Help Desk Analyst is responsible for assisting users with technical issues, and they have access to knowledge bases, troubleshooting guides, and other resources to investigate and resolve technology problems. They serve as the first point of contact for resolving issues.

Why other options are wrong

A. Database Administrator

A Database Administrator (DBA) specializes in managing and maintaining databases, but they are not typically focused on resolving broader technology problems outside of database management.

B. Trainer

A Trainer is someone who teaches others how to use technology, but they may not necessarily have direct access to technical resources for investigating issues.

C. CIO

A Chief Information Officer (CIO) oversees an organization's IT strategy and operations but does not typically deal with the day-to-day technical support or troubleshooting that requires access to a knowledge base.


8.

A user's computer is running slow. The recommended action is to add RAM. Besides opening the case and physically checking the RAM, how else could you determine the type of memory you need

  • Call another technician

  • Device Manager

  • Ask the user

  • Look on the Manufacturer's Website

Explanation

Correct Answer B. Device Manager

Explanation

Device Manager is a built-in tool in Windows operating systems that allows you to view hardware information, including the type of RAM installed on the system. By accessing the system’s memory properties through Device Manager, you can determine the memory specifications needed for upgrades or replacements.

Why other options are wrong

A. Call another technician

While another technician might help, this option is not as efficient as using tools like Device Manager to get the information directly from the computer itself.

C. Ask the user

The user may not be aware of the specific type of memory installed in their computer, especially if they haven't upgraded or checked it previously. Asking the user might not provide accurate information.

D. Look on the Manufacturer's Website

While the manufacturer's website can be helpful for finding compatible memory for a specific model, it is better to check directly from the system using Device Manager, as it provides precise information about the currently installed RAM.


9.

 What is the purpose of the control unit in the CPU

  • To perform arithmetic operations

  • To manage the flow of instructions

  • To store data

  • To handle input / output operations

Explanation

Correct Answer B. To manage the flow of instructions

Explanation

The control unit (CU) in the CPU is responsible for directing the operation of the processor. It manages the flow of instructions from memory to the appropriate processing units within the CPU, ensuring that operations are carried out in the correct order. It controls the sequence of operations and coordinates the other components of the CPU.

Why other options are wrong

A. To perform arithmetic operations

Performing arithmetic operations is the role of the arithmetic logic unit (ALU), not the control unit. The ALU handles operations like addition, subtraction, multiplication, and division.

C. To store data

Storing data is the function of registers or memory units, not the control unit. The control unit manages instructions and coordinates activities, but it does not store data directly.

D. To handle input / output operations

Handling input and output operations is typically managed by the input/output (I/O) systems and controllers, not the control unit. The control unit may send signals to initiate I/O operations, but it does not directly handle them.

Haven operates an e-commerce platform for her bridal store, which is secured with SSL encryption and has a valid digital certificate. What is the correct URL format for her secure website

Explanation

Correct Answer B. https://www.havenbridals.com

Explanation

The "https://" prefix indicates that the website is secured using SSL (Secure Sockets Layer) encryption, ensuring that data transmitted between the user's browser and the website is encrypted. This is standard for any secure website, especially those that handle sensitive information such as customer details and payment information.

Why other options are wrong

A. http://www.havenbridals.com

This URL does not indicate a secure connection, as it uses "http" instead of "https." Websites with only "http://" are not encrypted, making them less secure for handling sensitive customer data.

C. ftp://www.havenbridals.com

The "ftp://" prefix is used for File Transfer Protocol, which is a method of transferring files over the internet, not for secure web browsing. It is not used for regular website access, particularly not for e-commerce platforms.

D. www.havenbridals.com

While this URL could work for the website, it does not explicitly indicate whether the connection is secure. The lack of the "https://" means the website may not be secured with SSL encryption, which is important for handling sensitive customer information securely.
