Which of the following provides the BEST advantages for controlling security within the cloud?

  • Private cloud

  • Public cloud

  • Community cloud

  • Hybrid cloud

Correct answer: Private cloud

Companies are free to purchase virtualization software to provide their own cloud services for their organization. This does defeat a large portion of the benefits of the cloud that comes through scalability, cost-effectiveness, availability, reliability, and more. The primary advantage is that the organization has total control over the security within the cloud.

A public cloud is when cloud services are provided by a third party. A community cloud is a cloud where several organizations with a shared interest share cloud infrastructure together. A hybrid cloud is a combination of public and private cloud types.

What does UAC stand for, and what does it do?

  • User Account Control - Provides greater security for system changes

  • User Associated Changes - Displays user configuration changes

  • User Assisted Computing - More interactive and adaptive calculation methods

  • User Assembly Center - Provides framework for applications

Correct answer: User Account Control - Provides greater security for system changes

User Account Control (UAC) was a feature introduced with Windows Vista that was aimed at defeating malware root access. It forced users to be aware of changes to the system such as those during application installations. The idea was that if the user wasn't aware of any changes, they would deny the requested administrator access. 

The other answer choices are not accepted terminologies.

163.

Which SFC parameter allows the user to check and fix a specific file instead of all the system files?

  • /scanfile

  • /scannow

  • /verfiyonly

  • /verifyfile

Correct answer: /scanfile

System File Checker (SFC) is a command-line based utility that scans protected system files to check for and repair corruption. If you want SFC to scan one system file in particular, you would use the switch "/scanfile [FILENAME]".

The "/scannow" switch scans all files. The "/verfiyonly" switch scans all files but does not make changes. The "/verifyfile" switch checks a file but does not make changes.

164.

The common Ethernet standard for the 100BaseT over CAT-5 twisted-pair cable has a maximum speed of 100 Mbps and a maximum distance of how many meters?

  • 100 meters

  • 1,000 meters

  • 300 meters

  • 500 meters

Correct answer: 100 meters

100BaseT over CAT-5 allows for 100 Mbps transfer rates, but it has a maximum distance of 100 meters before the signal suffers from degradation.

165.

An administrator needs to run a UTP cable for 175 meters. What would be the simplest device to allow this to happen?

  • Repeater

  • Hub

  • Patch panel

  • Bridge

Correct answer: Repeater

A repeater just receives a signal and amplifies it. It does not do any analysis of the data. This allows you to make a signal travel farther than the 100m limit of a UTP cable. 

A hub is used to connect multiple computers. A patch panel is a large hub. A bridge connects multiple LANs.

166.

When you want to identify the chipset of a motherboard, where should you look?

  • In the manufacturer's documentation

  • On the motherboard

  • On the CPU

  • On the power supply

Correct answer: In the manufacturer's documentation

Because cooling elements such as heat sinks and heat spreaders are over the chipset, it can be impossible to determine what type it is based on looking at them. The only way to determine what chipset and version the motherboard contains is to refer to the documentation provided either with the motherboard itself or online.

167.

What is the name indicating the means by which a user interacts with an OS through the use of visuals?

  • GUI

  • Preemptive multitasking

  • Application

  • Driver

Correct answer: GUI

A graphical user interface (GUI) is how a user interacts with an OS. For example, Windows users are able to use a mouse and keyboard to interact with the operating system using icons and buttons. 

Preemptive multitasking is when an operating system allocates time to do a task before giving another process a turn. An application is a software package that performs a specific function. A driver is code that tells hardware how to work with an operating system.

168.

Which command, when entered into the command prompt, removes a folder?

  • rd

  • remdir

  • remdr

  • ren

Correct answer: rd

The "rd" command stands for "remove directory," and it deletes a directory. If you use "rd /s", you can remove all of the subdirectories and files along with the directory you specified.

The other answer choices are not system commands.

169.

An employee of a multi-national corporation has taken their Windows 10 laptop to a new city and wants to adjust the time zone. 

Which applet in the Control Panel should they use for this?

  • Date and Time

  • Regional and Language Options

  • Device Manager

  • Sync Center

Correct answer: Date and Time

You can fix the date, time, and time zone in the Date and Time applet. You can also adjust the date and time by right-clicking on the date and time at the bottom-right corner of the screen in the taskbar.

The Regional and Language Options set localization information. The Device Manager configures hardware devices. The Sync Center is a tool for syncing files across a network.

170.

What device must be installed on a laptop or desktop to connect the device to a network?

  • NIC

  • RAM

  • HDD

  • CPU

Correct answer: NIC

While each of these components might be needed, the Network Interface Card (NIC) is specifically needed for network connectivity. Most NIC cards will typically come with an RJ45 adapter for standard Ethernet configurations, though it is possible to get a NIC card for fiber-optic and even legacy 10Base networks.

RAM, HDD, and CPU are incorrect because they are necessary components for any computer to operate but do not provide network connectivity.

171.

What do we call the ability of a program to make several different requests of the CPU at the same time?

  • Multithreading

  • Multitasking

  • Multirequesting

  • Multilaning

Correct answer: Multithreading

Multithreading applications are capable of making multiple requests of the CPU to speed up processing and calculation times. Spreadsheet and database programs heavily depend on multithreading to provide more processing power for their calculations. 

Multitasking is when the CPU performs various takes simultaneously. The other answer choices are not accepted terminologies.

172.

To add Microsoft Exchange to an iPhone, what must the user select after going to the Settings menu?

  • Mail

  • General

  • Wi-Fi

  • Accessibility

Correct answer: Mail

After opening the Settings menu, choose Mail. From there, you can select "Accounts," "Add Account," and "Microsoft Exchange."

The General setting is for profile and device information. The Wi-Fi setting is for connecting to a Wi-Fi network. The Accessibility menu is for individual needs related to vision, speech, and physical access.

173.

Which of the following is immune to EMI?

  • Fiber

  • Copper

  • STP

  • UTP

Correct answer: Fiber

Fiber-optic cables do not use electricity for communications; rather, they depend solely on light. Because of this, fiber is completely immune to electromagnetic interference (EMI) and provides security because it can't be tapped or eavesdropped on. 

Copper coaxial, STP, and UTP are all affected by EMI to varying degrees.

174.

Which version of Windows does NOT include the Insider Program servicing channel for updates?

  • Enterprise LTSC

  • Enterprise

  • Home

  • Pro

Correct answer: Enterprise LTSC

Users of Windows 10/11 Enterprise LTSC (Long-Term Servicing Channel) get monthly updates through Windows Update. This is for devices that have one core purpose and do not meet feature updates.

Windows Home, Pro, and Enterprise can all use the Insider Program as well as the General Availability Channel.

175.

To configure WiFi on iOS devices, which icon do you press FIRST from the home screen?

  • Settings app

  • Home app

  • WiFi button

  • General button

Correct answer: Settings app

From the Home screen, tap the "Settings" icon. In the window that opens, tap "Settings." In the next window, you can then configure your WiFi settings.

Michelle is working as a help desk specialist at Acme Inc. An employee brings a laptop to Michelle and states that she is having issues with maintaining a battery charge and that the battery feels warm. Michelle inspects the device and has found that the battery pack looks a little larger than normal and slightly warped. What should be her next steps?

  • Immediately dispose of the battery and replace it with a new one

  • Replace the battery and return the defective one to the warehouse

  • Throw the old battery in the trash and replace it with a new one

  • Recharge the battery and test the longevity of the charge

Correct answer: Immediately dispose of the battery  and replace it with a new one.

Swollen batteries have reached the end of their lives and are now more prone to explosions and fire than before. They need to be handled carefully and be disposed of properly to ensure there is no risk of fire or explosion hurting any individuals. Swollen batteries can be caused by mismatched charging cables, age, defects in the battery, and overheating.

Returning to the warehouse, throwing it in the trash, or recharging could be dangerous in case of an explosion. 

177.

A company is in the process of selecting an operating system to run an application server. They want the operating system to be open-source so that they can fine-tune any system parameters that they want. 

Which operating system would be ideal for running their server?

  • Linux

  • Microsoft Windows

  • iOS

  • Mac OS X

Correct answer: Linux

Linux is a free and open-source operating system. Because it is open-source, you can make any modifications to it that you want.

Microsoft Windows, iOS, and Mac OS X are all closed-source operating systems. They do not meet the requirements of the company.

178.

Which of the following cleaning tools is BEST for cleaning up spilled toner?

  • Computer vacuum

  • Compressed air

  • Denatured isopropyl alcohol

  • Microfiber rag

Correct answer: Computer vacuum

Printer toner is a carcinogen when inhaled, so it is important to use a specialized vacuum with a finer filter to clean it up. This will dramatically reduce spreading and disturbing the toner where it can be inhaled. Furthermore, the computer vacuum is more insulated than a typical vacuum, so the toner will not ignite during cleanup.

Compressed air will spread the particles around. Denatured isopropyl alcohol should be used on metal contacts. A microfiber rag would be hard to clean the toner off of afterwards.

179.

For tape backups, Linear Tape-Open (LTO) backups can store up to what capacity per tape?

  • 6 TB

  • 800 GB

  • 500 GB

  • 1 TB

Correct answer: 6 TB

Linear Tape-Open (LTO) tapes store 6 TB of data, and will soon hold 48 TB. Tape backups are used for disaster recovery and hold large amounts of data in case of an emergency.

LTO tapes can store more than 800 GB, 500 GB, and 1 TB. 

180.

Which of the following BEST describes an HCL?

  • A list of hardware certified to work with specific software

  • A protocol for secure hardware communication

  • A hardware configuration for network devices

  • A certification for hardware repair technicians

Correct answer: A list of hardware certified to work with specific software

An HCL, or Hardware Compatibility List, is a list that details hardware components that have been tested and are known to work with specific software, particularly operating systems. This list is essential for ensuring compatibility and stable operation within systems. 

While important, protocols for secure hardware communication pertain to standards and methods for ensuring data security during hardware interactions, not to a compatibility list. Hardware configurations for network devices involve specific settings and setups for routers, switches, and other networking hardware. A certification would be a qualification that individuals earn, not a compatibility list. The CompTIA A+ itself is an example of a certification for IT professionals.
