Cisco Networking Quiz Module 5

What is the primary purpose of communication protocols?

• Define security policies

• Establish rules for data exchange

• Build physical networks

• Determine software compatibility

Answer explanation

The primary purpose of communication protocols is to establish rules for data exchange, ensuring that devices can communicate effectively and understand each other, which is essential for network functionality.

Why are communication standards important?

• They reduce network traffic

• They increase data transmission speed

• They ensure device interoperability

• They eliminate the need for routing

Answer explanation

Communication standards are crucial because they ensure device interoperability, allowing different devices and systems to work together seamlessly. This compatibility is essential for effective communication across diverse technologies.

Which organization is responsible for developing Ethernet standards?

• IETF

• IEEE

• ISO

• ITU

Answer explanation

The IEEE (Institute of Electrical and Electronics Engineers) is the organization responsible for developing Ethernet standards, ensuring interoperability and defining specifications for networking technologies.

What is the main purpose of communication models?

• To create new communication protocols

• To simplify network troubleshooting and design

• To enhance encryption methods

• To replace hardware components

Answer explanation

The main purpose of communication models is to simplify network troubleshooting and design. They provide a framework that helps in understanding and managing complex communication processes effectively.

Which protocol is responsible for reliable data delivery?

• UDP

• TCP

• HTTP

• DHCP

Answer explanation

TCP (Transmission Control Protocol) ensures reliable data delivery by establishing a connection and using error-checking mechanisms, unlike UDP (User Datagram Protocol), which does not guarantee delivery.

What does DNS do?

• Assigns IP addresses dynamically

• Resolves domain names into IP addresses

• Encrypts data during transmission

• Manages file transfers

Answer explanation

DNS (Domain Name System) primarily resolves domain names into IP addresses, allowing users to access websites using easy-to-remember names instead of numerical IP addresses.

Which protocol is used for sending emails?

• FTP

• SNMP

• SMTP

• DHCP

Answer explanation

The correct protocol for sending emails is SMTP (Simple Mail Transfer Protocol). It is specifically designed for email transmission, unlike FTP (File Transfer Protocol), SNMP (Simple Network Management Protocol), and DHCP (Dynamic Host Configuration Protocol).

What is the primary difference between TCP and UDP?

• TCP is faster than UDP

• UDP provides error-checking, TCP does not

• TCP is reliable, UDP is not

• UDP works only on wireless networks

Answer explanation

The primary difference is that TCP is a connection-oriented protocol that ensures reliable data transmission, while UDP is connectionless and does not guarantee delivery, making TCP reliable and UDP unreliable.

What is the function of DHCP?

• Encrypt network traffic

• Provide automatic IP addressing

• Route data between networks

• Secure email transmissions

Answer explanation

The function of DHCP (Dynamic Host Configuration Protocol) is to provide automatic IP addressing to devices on a network, allowing them to communicate without manual configuration.

Which protocol ensures secure web communication?

• HTTP

• FTP

• HTTPS

• SNMP

Answer explanation

HTTPS (HyperText Transfer Protocol Secure) ensures secure web communication by encrypting data between the user's browser and the web server, unlike HTTP, which is not secure.
