Question 1

____ refers to dialing directly into a private network's or ISP's remote access server to log on to a network.
A) Dialed networking
B) Traditional networking
C) Dial-up networking
D) Virtual networking

Accepted Answer

Dial-up networking refers to dialing directly into a private network's or ISP's remote access server to log on to a network. This was a common method of connecting to the internet in the past, where a user would use a modem to dial a phone number provided by the ISP to establish a connection.

Question 2

A ____ uses very little hard disk space or processing power from the workstation on which it is installed.
A) thick client
B) fat client
C) thin client
D) virtual client

Accepted Answer

A thin client is a lightweight software application that requires minimal hardware resources from the workstation on which it is installed. Its processing power and storage requirements are primarily fulfilled by a central server, thus reducing the burden on the client workstation. Thick clients, on the other hand, require a significant amount of processing power and storage capacity on the client machine, while virtual clients are software applications that simulate the behavior of a physical computer and require moderate hardware resources. Fat clients are a less common term used interchangeably with thick clients.

Question 3

PPTP and L2TP are the only protocols that can be used to carry VPN traffic.

Accepted Answer

There are several VPN protocols that can be used to carry VPN traffic, including OpenVPN, IPSec, and SSL/TLS. PPTP and L2TP are just two of the many VPN protocols available.

Question 4

____ mode is appropriate for test networks or if you simply need to install a different operating system on your workstation to use a program that is incompatible with your host's operating system.
A) Host-only
B) NAT
C) Bridged
D) Blocked

Accepted Answer

Host-only mode allows the virtual machine to communicate only with the host machine, making it a good choice for test networks or running an operating system that is incompatible with the host machine's operating system. NAT and Bridged modes allow the virtual machine to access the physical network, which may not be necessary or desirable in these scenarios. Blocked mode prevents any network access, which is not necessary for installing a different operating system.

Question 5

Using a virtualization program, you can create dozens of different VMs.

Accepted Answer

With a virtualization program, you can create multiple virtual machines (VMs) on a single physical machine, allowing you to run different operating systems and applications within each VM. Therefore, it is possible to create dozens of VMs depending on the resources of the physical machine.

Question 6

In the NAT networking mode, a vNIC relies on the ____ to act as a NAT device.
A) guest machine
B) reference machine
C) host machine
D) management machine

Accepted Answer

In NAT networking mode, the vNIC relies on the host machine to act as a NAT device. The host machine shares its IP address with the guest machine, allowing the guest machine to access the network through the host's IP address.

Question 7

____ connect vNICs with a network, whether virtual or physical.
A) Virtual routers
B) Virtual crossovers
C) Virtual duplexers
D) Virtual bridges

Accepted Answer

A virtual bridge is used to connect vNICs to a network, whether virtual or physical. It operates similarly to a physical network bridge, forwarding traffic between networks based on MAC addresses. Virtual routers are used to route traffic between different networks, virtual or physical. Virtual crossovers and duplexers are not commonly used terms in the context of networking.

Question 8

To connect to a network, a virtual machine requires a ____.
A) virtual switch
B) virtual adapter
C) physical switch
D) virtual MAC address

Accepted Answer

A virtual machine requires a virtual adapter to connect to a network, as it acts as the network interface for the VM.

Question 9

The physical computer on a virtual machine is known as a ____.
A) guest
B) client
C) host
D) server

Accepted Answer

The physical computer that runs one or more virtual machines is known as the "host." This term distinguishes it from the "guest" virtual machines that run on it.

Question 10

Most cloud service providers use virtualization software to supply multiple platforms to multiple users.

Accepted Answer

Virtualization software allows cloud service providers to create and run multiple virtual environments on a single physical server, allowing for multiple platforms to be offered to multiple users.

Question 11

____ is the most widely implemented virtualization software today.
A) Hyper-V
B) Citrix
C) VirtualBox
D) VMware

Accepted Answer

VMware is the most widely implemented virtualization software today, as it provides a comprehensive set of features, supports multiple operating systems, and has a large user community. Other options like Hyper-V, Citrix, and VirtualBox also have their advantages but are not as popular as VMware.

Question 12

Each VM is known as a ____.
A) guest
B) host
C) client
D) node

Accepted Answer

A VM is a virtual machine, which runs on a physical server, known as the host. The VM is called a guest, as it is not the primary or main operating system on the physical server, but rather a virtualized instance running within it. The terms client and node are often used in networking contexts and are not as relevant to virtualization.

Question 13

Upon creation, each vNIC is automatically assigned a ____.
A) MAC address
B) switch address
C) block address
D) reference address

Accepted Answer

Each virtual NIC (vNIC) is automatically assigned a Media Access Control (MAC) address upon creation. This MAC address is a unique identifier that is used by the network to identify and communicate with the vNIC.

Question 14

____ is an open source system designed to allow one workstation to remotely manipulate and receive screen updates from another workstation.
A) Remote Desktop
B) VNC
C) Citrix
D) Xen

Accepted Answer

VNC (Virtual Network Computing) is an open source system designed for remote desktop access and control. It allows one workstation to remotely manipulate and receive screen updates from another workstation.

Question 15

The software required to establish VPNs is usually expensive.

Accepted Answer

This statement is incorrect. There are many free and open-source VPN software available that can be used to establish VPNs without any cost. Additionally, many VPN service providers also offer their own software for free or at a relatively low cost. However, there are also some premium VPN software with advanced features that can come with a price tag.

Question 16

A VM must use the same operating system, type of CPU, storage drive, and NIC as the physical computer it resides on.

Accepted Answer

A VM can use a different operating system, type of CPU, storage drive, and NIC than the physical computer it resides on. In fact, one of the benefits of virtualization is the ability to run multiple operating systems and different hardware configurations on a single physical host.

Question 17

When a server compares a user's credentials with those in its database, the process is known as ____.
A) authorization
B) authentication
C) administration
D) accounting
