Cloud Computing Technology Basics - Quiz

What is the main function of networking in cloud computing?

• To store data

• To enable communication between cloud resources and users

• To manage power in data centres

• To provide security for applications

Answer explanation

The main function of networking in cloud computing is to enable communication between cloud resources and users, facilitating data transfer and interaction across the cloud environment.

What device connects multiple devices within a local network and improves efficiency?

• Router

• Modem

• Switch

• Firewall

Answer explanation

A switch connects multiple devices within a local network, allowing them to communicate efficiently by directing data only to the intended recipient, unlike a router which connects different networks.

Which networking device is responsible for directing data between different networks?

• Hub

• Router

• Load balancer

• Proxy server

Answer explanation

A router is the device that directs data between different networks, making it essential for connecting multiple networks and managing traffic. In contrast, hubs, load balancers, and proxy servers serve different functions.

What does the TCP protocol ensure in the TCP/IP suite?

• Encryption of data

• Reliable data transmission

• Wireless connectivity

• Faster internet speeds

Answer explanation

The TCP protocol ensures reliable data transmission by establishing a connection-oriented communication, which includes error checking and data retransmission, making it essential for accurate data delivery in the TCP/IP suite.

What is the role of DNS in cloud computing?

• Encrypts user passwords

• Manages network bandwidth

• Translates domain names into IP addresses

• Controls cloud storage permissions

Answer explanation

DNS (Domain Name System) translates domain names into IP addresses, enabling users to access cloud services using easy-to-remember names instead of numerical IP addresses. This is essential for the functionality of cloud computing.

What is the function of DHCP in a network?

• Assigns IP addresses dynamically

• Blocks unauthorized network access

• Monitors server temperatures

• Encrypts network traffic

Answer explanation

DHCP (Dynamic Host Configuration Protocol) is responsible for assigning IP addresses dynamically to devices on a network, ensuring they can communicate effectively without manual configuration.

Which factor affects the performance of cloud computing by determining data transmission capacity?

• Bandwidth

• DNS

• Hypervisor

• DHCP

Answer explanation

Bandwidth is the key factor that affects cloud computing performance by determining the data transmission capacity. Higher bandwidth allows for faster data transfer, improving overall efficiency and user experience.

Which of the following is NOT a measure of network availability?

• Bandwidth

• Internet Access

Answer explanation

Bandwidth refers to the maximum data transfer rate of a network, not its availability. Internet access is a measure of availability, while bandwidth is more about capacity.

Why is Linux a popular choice for cloud computing?

• It is expensive and proprietary

• It is an open-source, stable, and secure operating system

• It is only used for gaming applications

• It does not support cloud services

Answer explanation

Linux is a popular choice for cloud computing because it is an open-source, stable, and secure operating system, making it ideal for scalable and reliable cloud environments.

What type of database is MySQL?

• NoSQL

• Relational Database Management System (RDBMS)

• File-based Storage System

• Graph Database

Answer explanation

MySQL is a Relational Database Management System (RDBMS) because it uses structured query language (SQL) for managing and manipulating relational data, organizing it into tables with defined relationships.
