Question 3

Which of the following is true of a VPN (virtual private network)?

Accepted Answer

A VPN (virtual private network) provides a secure connection over the public internet by encrypting data during transmission, ensuring privacy and confidentiality. It creates a virtual tunnel that allows remote workers or branch offices to securely access an organization's internal network, resources, and services. Therefore, option A is the correct choice. Option B is incorrect because a VPN is not a physical pathway, but a logical one created using software and encryption protocols. Option C is also incorrect because remote access is one of the primary benefits of a VPN. Option D is incorrect because one of the key features of a VPN is its ability to encrypt messages and protect data during transmission.

Question 4

A small company is likely to choose IaaS as it does not require much technical expertise to load operating systems on a server.

Accepted Answer

IaaS (Infrastructure-as-a-Service) requires technical expertise to manage and maintain the underlying servers and networking infrastructure.

The organisation does not need to purchase a license for software replication, install an operating system or install a DBMS as these tasks are handled by the service provider.

A vendor providing SaaS usually makes the software available as a thin-client, which means that the software is accessed through a web browser rather than being installed locally on the user's device.

Question 12

Which of the following statements is true of a virtual private cloud (VPC)?

Accepted Answer

A virtual private cloud (VPC) is a virtual network that simulates a private cloud environment within a public cloud. Therefore, a VPC can be built on public cloud infrastructure. Option A is incorrect because a VPC can be accessed from outside the organization if the appropriate network settings are configured. Option B is also incorrect because an organization may choose to store sensitive data on-premises or on a private cloud instead of a VPC. Lastly, a VPC can make use of VPN technology to ensure secure and private communication over the internet. Therefore, option C is also incorrect.

Question 13

Question 18

What is a VPN (virtual private network)?

Accepted Answer

A VPN (virtual private network) is a technology that uses the Internet to create secure point-to-point connections. It allows users to connect to a network securely over a public network such as the Internet. VPNs provide a secure and private way of connecting to the Internet and accessing resources on a remote network.

Question 19

Which of the following is a characteristic of a virtual private network (VPN)?

Accepted Answer

A virtual private network (VPN) sends encrypted messages over the public Internet, making it a secure way to access sensitive information remotely. A VPN does not establish a physical connection between the client and the server, but rather creates a virtual "tunnel" for secure data transmission. VPNs can be accessed from multiple geographical locations, as long as the user has the necessary credentials and the VPN server is accessible over the Internet.

Question 20

Which of the following is an advantage of using a private cloud over a virtual private cloud (VPC)?

Accepted Answer

A private cloud, being completely isolated from other public clouds, may offer more flexibility when it comes to hosting sensitive data. This is because a VPC still operates on a shared infrastructure or hardware, which might require approval from regulatory bodies to ensure that data is stored securely.
