Networking Concepts Assessment

Kabir is managing a large office network for his company. He needs to divide this network into smaller, more manageable sections for better security and performance. What is this process called and why is it used?

• Subnetting is used to create smaller networks within a larger network for better management and security.

• Subnetting is used to eliminate the need for IP addresses.

• Subnetting is a method to increase the size of a network.

• Subnetting is a technique for improving internet speed.

Mira is setting up a new network for her school project and needs to calculate the number of hosts that can be accommodated in her subnet. How does she calculate the number of hosts in a subnet?

• 2^(32 - subnet mask bits) - 2

• 2^(32 + subnet mask bits) + 2

• 2^(subnet mask bits) - 2

• subnet mask bits * 2

Aashi is setting up a new office network and needs to configure the devices. What is the purpose of a subnet mask?

• To assign static IP addresses to devices.

• To determine the speed of the network connection.

• To identify the network and host portions of an IP address.

• To encrypt data transmitted over the network.

Siya is setting up a home network and wants to understand the difference between public and private IP addresses.

• Public IP addresses are unique on the internet, while private IP addresses are used within local networks and are not routable on the internet.

• Public IP addresses are assigned by local ISPs, while private IP addresses are assigned by the government.

• Private IP addresses can be routed on the internet, while public IP addresses cannot.

• Public IP addresses are used within local networks, while private IP addresses are unique on the internet.

During a networking class, Kiara asked her professor, "What is CIDR and how does it relate to subnetting?"

• CIDR eliminates the need for any subnetting.

• CIDR is a method for IP address allocation that allows for flexible subnetting.

• CIDR is only used for IPv6 addresses.

• CIDR is a type of firewall configuration.

Advait is learning about computer networking in his class. He wants to know how to convert a decimal subnet mask to binary for his project.

• Use only the first octet for conversion.

• Convert each decimal octet to binary and concatenate.

• Convert the binary mask to hexadecimal first.

• Add the binary values of each octet together.

Aarav wants to visit a website to learn about networking. What is the role of DNS in networking?

• DNS translates domain names to IP addresses, enabling users to access websites.

• DNS stores website content for faster access.

• DNS manages network security protocols.

• DNS provides email routing services.

During a group project, Ishika needs to send an important email to her team members about their progress. How does the SMTP protocol function in this scenario?

• SMTP is a protocol used for sending emails from a client to a server and between servers.

• SMTP is used for receiving emails only.

• SMTP is a file transfer protocol for large files.

• SMTP encrypts emails during transmission.

Tara is browsing the internet and comes across two websites. One website uses HTTP, while the other uses HTTPS. What are the main differences between HTTP and HTTPS?

• HTTPS is faster than HTTP due to less data transfer.

• HTTP uses encryption, while HTTPS does not.

• HTTP is unsecured, while HTTPS is secured with SSL/TLS encryption.

• HTTP is only used for web pages, while HTTPS is for all types of data.

Avni needs to send a large presentation file to her colleague Dhruv. She decides to use a method that allows her to transfer files between their computers over a network. What is this method called?

• FTP is a protocol used for transferring files between computers over a network.

• FTP is a cloud service for online backups.

• FTP is a programming language for web development.

• FTP is a type of hardware for file storage.
