CompTIA Hardware Practice Test #1
Choose the option that best illustrates key attributes cloud computing from the list below.
Correct answer: Scalable, Shared, Metered Usage, Service, Virtualization
Virtualization is a key enabler of the first four of cloud computing's five key attributes.
Which of the following choices incorrectly defines the functionality of parity RAM or parity memory?
Correct answer: Parity RAM has the ability to self-correct identified errors.
A parity bit is used in parity memory or parity RAM (Random Access Memory) to identify mistakes. Parity memory is excellent for identifying mistakes but provides no means of correcting them once they occur. Error-correcting code memory (ECC) allows for automatic error repair but not parity memory.
Which of the following is a synonym for the word "Hypervisor"?
Correct answer: Virtual Machine Monitor (VMM)
A Hypervisor can be known as a Virtual Machine Monitor or Virtual Machine Manager.
Which of the following is NOT an advantage of utilizing cloud infrastructure?
Correct answer: The Cloud Provider will handle security on your behalf
The Cloud infrastructure, like any infrastructure, nevertheless requires extra precautions to maintain its security. The pay-as-you-go model (typically per second or per minute billing), the ability to create and delete servers on demand or automatically, and the ease of provisioning complex services such as database clusters without highly specialized experts are just a few of the advantages of cloud infrastructure.
Your manager has requested that you bring him a DE-15 connection. Which of the following does he mean?
Correct answer: VGA
VGA has a 15-pin DE connector.
The following characteristics are shared by virtualization and cloud computing:
Correct answer: All of the above
Resources must be highly configurable and adaptable in order to support these features.
Which of the following statements about M.2 drive is correct?
Correct answer: M.2 drives are directly connected to the motherboard
M.2 drives connect directly to the motherboard and do not require any power or data connections.
What kind of connector is often used to transfer electricity from a PC's power supply to an internal hard drive, CD or DVD drive?
Correct answer: Molex
Molex connectors can be found in older desktop PCs and supply power to components such as hard drives and CD drives. Because most current PCs use SATA disks with specific SATA Power cords, the use of Molex connections has declined dramatically.
What is the name of the native hypervisor available in Windows 10 Pro and higher?
Correct answer: Hyper-V
Hyper-V is a native hypervisor that is included with various versions of Windows 10 and Windows Server. It's worth noting that Hyper-V isn't supported in Windows 10 Home. LXD is a hypervisor that operates on Linux operating systems, whereas ESXi is a VMWare proprietary hypervisor that runs directly on a host computer (bare metal) without the requirement for a host operating system.
What special operating system setup is required when running Windows 10 as a virtual machine?
"Correct answer: There is no need for any specific configuration
When running Windows 10 on a virtual computer, no special configuration is required. Hypervisors provide virtual resources (CPU, Memory, etc.) that appear to be real hardware, allowing operating systems to be installed and operate in the same way that they would on physical hosts."
Which of the following is NOT a benefit for Cloud Computing for business?
Correct answer: Virtually infinite scalability of infrastructure
Scalable infrastructure is a technical benefit of cloud computing, not an economic benefit. Of course, this is still indirectly helpful to a business, but most non-IT department workers at a company will be unfamiliar with the term "scalable infrastructure." It is critical to be able to communicate the commercial and technical benefits of various computing alternatives to your target audience.
What component contributes to the separation of network traffic across virtual machines on the same physical host?
Correct answer: Virtual NIC
Each virtual host will have one or more Virtual Network Interface Cards (VNICs) (NIC). These Virtual NICs are used to redirect network traffic to each virtual host instead of delivering it to all hosts on a server. This is significant because cloud providers frequently host several customers' virtual servers on the same physical server (Resource Pooling).
Which of the following statements best defines RAID 10?
Correct answer: RAID 10 offers data redundancy as well as quicker performance.
RAID 10 (also known as RAID 1 + 0) combines RAIDs 1 and 0 into a single disk array, providing data redundancy as well as quicker performance.
Which video cable is capable of transmitting both digital and analog signals?
Correct answer: DVI-I
DVI-I (Digital Visual Interface - Integrated) may transmit both digital and analog signals. Digital only cable options include DVI-D (Digital), HDMI, and Mini-HDMI.
Which of the following statements about NVMe is correct?
Correct answer: NVMe is a data access protocol
Non-Volatile Memory Express (NVMe) is a protocol that provides extremely fast access to Solid State Drives (SSDs). The key point to remember about NVMe is that it simply describes how data is read and transmitted. The NVMe protocol is supported by M.2 and PCIe-based SSDs. NVMe cannot be compared to M.2 since M.2 is a physical form factor standard rather than a protocol. Consider NVMe to be the logical side, whereas M.2 is the physical side.
Which of the following is an advantage of having a multi-core processor?
Correct answer: Multiple threads can be managed at the same time
Threads are used by processors to execute computations, and each processor core can only handle one thread at a time. Additional cores enhance processor speed by allowing several threads to execute at the same time. When several threads are used in an application on a single core CPU, the threads do not operate concurrently, restricting performance.
Which of the following options supports Hardware-Assisted Virtualization (HAV)?
Correct answer: VT-x
Intel's VT-x technology enables Hardware Assisted Virtualization (HAV). HAV allows virtual hosts to utilise CPUs in an isolated manner.
What kind of connector with 40 pins is utilized for internal hard drives?
Correct answer: IDE
IDE (also known as Parallel ATA) contains 40 or 80 pins, with the latter being considerably more typical.
