Module 10: Virtualization, Cloud Computing, and Printers Flashcards
One of the users in your company is asking if he can install an app on his company-provided mobile device. The installation of apps by users is blocked on the company’s mobile devices, but you have tested and confirmed this app would be useful for everyone.
Which of the following will allow users to request a minimal version of the app that downloads only what is required to run?
Application streaming
Application streaming is on-demand software delivery in which a user requests an app, the app is packaged, and minimal code is sent to the client. If additional code is needed, the client will pull that code from the server. When the app is closed, the code can be cached for offline use or removed.
A Windows computer is shared between several users, each with his own local user account. Each user has his own dedicated, uniquely configured VM stored in a public folder on the computer.
Which of the following steps should be taken to secure the VMs so no user can copy or delete another user’s VM files? (Select TWO.)
Secure the VM files with permissions.
Apply encryption to the VM files.
Applying appropriate file/folder permissions to the files associated with a VM will protect the files from unauthorized access. Encrypting the files will provide another level of protection.
Encrypting the files associated with a VM will protect the files from unauthorized access. It is best practice to also apply file/folder permissions to the files.
Mary’s company has asked her to research new computers. The company wants to provide workers with minimal computers that have an operating system and a browser that will allow the workers to connect to a server. The server will do most of the necessary processing.
What kind of computer should Mary recommend?
Thin client
A thin client is a computer that has an operating system but little computing power of its own and might need to support only a browser used to communicate with the server. The server does most of the processing, while the user interacts directly with the thin client.
Kendra, a user, would like to share her serial printer that has no networking connectivity with the other users in her small office.
Which of the following would be the best choice for providing this functionality with the least effort and cost to the user?
Enable print sharing on the computer.
The printer is already connected and functioning using a directly attached RS-232 connection. The easiest, least costly method is to enable print sharing on the computer.
The administrative assistant of the company’s CEO is asking about a printer for her use only. It seems the shared department printer is overused, making the assistant wait to print the CEO’s last minute documents.
Which of the following technologies will best meet the administrative assistant’s request? (Select TWO.)
Bluetooth printer
Local printer
A Bluetooth connected printer would be an excellent wireless option for a single user whose computer is in close proximity to the printer.
A local printer is connected to modern computers using wired USB and would be a perfect solution for a printer to be used by one individual.
A company purchased a high-quality color laser printer to print color brochures and sales proposals. The printer is connected to a marketing PC via USB and is configured as a shared local printer for use by the sales and marketing teams. The manager is concerned about the cost of consumables for the printer and does not want users to unintentionally print to the printer.
What can be done to ensure that only authorized users can send print jobs to the printer?
Enable user authentication on the printer share.
Security is configured for a shared local printer on the computer that is performing the sharing. On the printer’s Properties dialog box, click the Security tab and set who has access to the printer and his allowed permissions.
Which of the following is the correct order for the steps of laser printing?
Processing, charging, exposing, developing, transferring, fusing, cleaning
This list is the correct order for the laser printing process.
A new printer has been added in your office and connected to a WAP for use by all users in the company.
Which of the following best describes the method of connectivity for the new printer?
Wireless infrastructure mode
Wireless infrastructure mode is a connectivity method in which devices connect to a central connectivity device such as a WAP (wireless access point). This would be the most likely wireless method of connectivity for a shared printer connected to a WAP.
Which of the following components provides the physical network connectivity for a virtual machine, managed by a Type 2 hypervisor, to connect to an Ethernet switch via a UTP patch cable?
Host computer’s physical network interface.
The host’s physical NIC is connected to the Ethernet LAN using a physical patch cable. The VMs virtual NIC is connected to the physical NIC, completing the connection.
A user is experiencing garbled print on each page printed from her printer.
Which of the following would be a probable cause for the garbled print? (Select TWO.)
Print drivers are corrupt or need to be updated.
An application on the computer is sending garbled print.
Corrupt print drivers will often produce garbled print. Updating the drivers may very well solve this issue.
The application on the computer can cause garbled print. Try printing from another application, and if the problem disappears, reinstall or repair the application.
You have been tasked with performing routine maintenance on an inkjet printer. After printing a test page, you notice missing lines of print in various areas throughout the page.
Which of the following should you do to resolve this issue? (Select TWO.)
Run the head cleaning utility.
Manually clean the print nozzles.
The first step in resolving an issue of missing lines on an inkjet printer is to run the head cleaning utility. This is typically done from the Services tab in the printer Properties dialog box, installed as an application or is launched from the printer’s control panel.
If after running the print head cleaning utility, the printer is still missing lines, you can manually clean the print head using distilled water and a cotton swab. If manual cleaning does not resolve the issue, the print head or print cartridge will need to be replaced.
The accounting department has implemented thin clients and VDI. One of the users is complaining that each time she powers on her thin client, she has access only to a web browser.
Which of the following is the most likely reason for this behavior? (Select TWO.)
The user has not signed in to the VDI server with her user account and password.
The user has entered incorrect credentials to the VDI server.
When a thin client in a VDI environment is powered on, the user launches a web browser, connects to the VDI provider, and signs in to receive her desktop. In the scenario, the user has access only to a browser, so she has not yet signed in.

You are troubleshooting an inkjet printer that prints areas on the page with random voids and missing colors.
Which of the following will best help resolve the problem? (Select TWO.)
Printer calibration
Head cleaning utility
Inkjet printers have a maintenance cycle in the print driver settings, within a separate application, or built into the printer console. Running a calibration should be performed after a head cleaning cycle. If the problem persists, the printhead or ink cartridges should be replaced.

Running a head or nozzle cleaning is the first step to take in this scenario. If the problem persists, try running a printer calibration. If the problem persists, the printhead or ink cartridges should be replaced.
A help desk technician needs to run virtual machines on her laptop computer for several upcoming training sessions.
Which of the following must be completed before she can use virtualization on her laptop?
Enable virtualization support in the laptop’s UEFI.
Most (if not all) modern virtualization software applications require HAV (hardware-assisted virtualization) to be enabled. Intel support is called Intel VT, and AMD support is called AMD-V. This feature, if supported by the motherboard, is enabled in the BIOS/UEFI.
Which of the following are advantages of implementing cloud computing over services hosted internally? (Select THREE.)
Rapid elasticity
On-demand services
Metered services
Rapid elasticity provides customers with scalable services that can be automatically scaled up or down depending on need.
On-demand is a self-service model in which a customer can purchase cloud computing capabilities that are provisioned with minimal management effort or service provider interaction. In other words, let me easily get the service I need, when I need it, with no help at all from the provider.
Metered service is a cost-effective way to pay for only what you use.
