CIST 1601: Chapter 9 Quiz

Which of the following is used as a secure tunnel to connect two networks?

• VLAN

• VAN

• VFA

• VPN

Answer explanation

A VPN is used as a secure tunnel to connect two networks. It creates a private and encrypted connection over the internet, ensuring that the data transmitted between the connected networks is secure and protected from unauthorized access.

Which of the following is an advantage of software-defined networking (SDN)?

• Is currently a new technology

• Standards are still being developed

• More granular control

• Lack of vendor support

Answer explanation

SDN allows for centralized control of network infrastructure using software applications. This centralized control enables administrators to have more precise and granular control over network traffic, configuration, and management, leading to increased flexibility, efficiency, and responsiveness in network operations.

Which of the following is an advantage of a virtual browser?

• Protects the host operating system from malicious downloads

• Prevents adware and spyware that monitor your internet activity

• Prevents phishing and drive-by downloads

• Filters internet content based on ratings

Answer explanation

A virtual browser operates in an isolated environment, preventing potentially harmful downloads from affecting the host operating system. This isolation helps protect the underlying system from malware and other security threats that may be encountered while browsing the internet.

Which load balancing method distributes a workload across multiple computers?

• Resource pooling

• Virtualization

• Bottleneck

• Workload balancing

Answer explanation

Workload balancing involves optimizing the distribution of tasks or processes among various computing resources to ensure efficient utilization and prevent overload on any single component.

What is a virtual LAN that runs on top of a physical LAN called?

• VLAN

• VAN

• VFA

• VMM

Answer explanation

VAN is a less common term but could be used to describe a network concept similar to VLAN, emphasizing the virtual aspect. VAN stands for Virtual Area Network.

What is the limit of virtual machines that can be connected to a virtual network?

• 1,000

• 10,000

• 100,000

• Unlimited

Which of the following devices facilitates communication between different virtual machines by checking data packets before moving them to a destination?

• Virtual Switch

• Virtual Router

• VLAN

• VFA

Answer explanation

The device that facilitates communication between different virtual machines by checking data packets before moving them to a destination is commonly known as a Virtual Switch. A Virtual Switch operates at the data link layer (Layer 2) of the OSI model and is responsible for forwarding network traffic between virtual machines within the same virtualized environment. It checks data packets, manages network traffic, and ensures that communication between virtual machines is efficient and secure. Virtual switches are a key component in virtualized environments, such as those created using hypervisors like VMware, Hyper-V, or VirtualBox.

Which of the following statements about virtual networks is true? (Select two.)

• A virtual network is independent of the configuration and physical hardware of the host operating system.

• A virtual network is dependent on the configuration and physical hardware of the host operating system.

• Each virtual network must be associated with a single physical network adapter.

• Multiple virtual networks can be associated with a single physical network adapter.

• 1. Accessing network resources requires that the operating system on the virtual machine be configured on an isolated network.

Which type of hypervisor runs as an application on the host machine?

• 1

• 2

• 3

• 4

Answer explanation

The type of hypervisor that runs as an application on the host machine is known as a Type-2 hypervisor or a hosted hypervisor. This hypervisor is installed on top of an existing operating system, and it relies on the host operating system for resource management. Examples of Type-2 hypervisors include VMware Workstation, Oracle VirtualBox, and Microsoft Hyper-V when installed on a Windows desktop. They are often used for development, testing, or running virtual machines on personal computers or workstations.

You have a development machine that contains sensitive information relative to your business. You are concerned that spyware and malware might be installed while users browse websites, which could compromise your system or pose a confidentiality risk. Which of the following actions would BEST protect your system?

• Run the browser within a virtual environment.

• Configure the browser to block all cookies and pop-ups.

• Run the browser in protected mode.

• Change the security level for the internet zone to High.
