CCNA sample questions set 11

In this article, I describe some CCNA sample questions for practice before appearing in the CCNA 200-301 exam. The following questions are basic questions and related to the CCNA sample questions set 11. There are multiple sample questions set on this website for prior practice online. All questions are described with relevant answers. You can take the following questions and answer as reference for CCNA 200-301 exam. You may also need to do more practice with other websites and books to practice the CCNA sample questions set 11. 

Question 1: What is the purpose of the OSI model?

The OSI (Open Systems Interconnection) model is a conceptual framework that was developed to standardize the communication protocols used in computer networks. Its purpose is to provide a clear and consistent method for communication between different systems, regardless of the specific hardware or software they use.

The OSI model is divided into seven layers, with each layer responsible for specific communication functions. These layers are:

• 1. Physical layer
• 2. Data link layer
• 3. Network layer
• 4. Transport layer
• 5. Session layer
• 6. Presentation layer
• 7. Application layer

By dividing communication into these layers, the OSI model provides a clear understanding of how data moves through a network, and allows for easier development and implementation of new networking technologies. It also provides a standardized way for different vendors and systems to communicate with each other, which promotes interoperability and makes it easier to create and maintain complex networks. This is the answer to question 1 of CCNA sample questions set 11.

Question 2. What is a network protocol?

A network protocol is a set of rules and standards that govern the communication between devices in a computer network. It defines the format and sequence of messages that are exchanged between devices, as well as the actions that are taken in response to those messages.

Network protocols can be categorized into different layers based on the OSI model, with each layer responsible for a different aspect of communication. For example, some common network protocols include:

• 1. Ethernet: A protocol that operates at the Data Link layer and governs the transmission of data over a physical network.
• 2. IP (Internet Protocol): A protocol that operates at the Network layer and provides addressing and routing functionality, allowing data to be transmitted across different networks.
• 3. TCP (Transmission Control Protocol): A protocol that operates at the Transport layer and provides reliable, connection-oriented data delivery.
• 4. HTTP (Hypertext Transfer Protocol): A protocol that operates at the Application layer and governs the transfer of data over the World Wide Web.

Network protocols are essential for enabling communication between devices on a network, and for ensuring that data is transmitted reliably and efficiently. Without network protocols, devices would not be able to communicate with each other in a standardized and consistent way, which would make it difficult to build and maintain complex networks. This is the answer to question 2 of CCNA sample questions set 11.

Question 3. What is a subnet?

A subnet (short for “subnetwork”) is a smaller network that is created by dividing a larger network into smaller segments. Subnets are commonly used in computer networks to improve performance, security, and manageability.

When a network is divided into subnets, each subnet is assigned a unique network address and a range of host addresses. The network address identifies the subnet itself, while the host addresses are used to identify individual devices within the subnet.

By dividing a network into subnets, traffic can be isolated and contained within each subnet, reducing the amount of traffic that needs to be transmitted across the larger network. This can improve performance and reduce network congestion.

Subnets can also be used to improve security by creating smaller, more manageable security domains. By restricting access between subnets, it is possible to limit the impact of security breaches and minimize the risk of unauthorized access to sensitive data.

Finally, subnets can be used to simplify network management by grouping devices with similar characteristics or requirements together. This can make it easier to administer and maintain the network, and can help to ensure that devices are configured and managed in a consistent and standardized way. This is the answer to question 3 of CCNA sample questions set 11.

Question 4. What is the difference between a router and a switch?

A router and a switch are both networking devices, but they serve different functions in a network.

A switch is a device that is used to connect multiple devices together on a local area network (LAN). It operates at the Data Link layer (layer 2) of the OSI model, and uses MAC addresses to forward data between devices on the same network segment. Switches are commonly used in networks to improve performance by reducing collisions and network congestion, and to provide greater bandwidth to individual devices.

A router, on the other hand, is a device that is used to connect multiple networks together. It operates at the Network layer (layer 3) of the OSI model, and uses IP addresses to forward data between networks. Routers are commonly used to connect LANs to the Internet, or to connect different LANs together. They are also used to provide security by implementing firewall and NAT (Network Address Translation) functionality.

In summary, the main difference between a router and a switch is that a switch is used to connect devices within a network, while a router is used to connect different networks together. While switches operate at the Data Link layer and use MAC addresses to forward data between devices, routers operate at the Network layer and use IP addresses to forward data between networks. This is the answer to question 4 of CCNA sample questions set 11.

Question 5. What is TCP/IP?

TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of communication protocols used for communication over the Internet and most modern computer networks. It is the most widely used networking protocol suite in the world.

TCP is a connection-oriented protocol that ensures reliable and ordered delivery of data between devices on a network. It breaks data into packets, assigns sequence numbers to each packet, and ensures that packets are transmitted and received in the correct order. TCP also handles flow control, congestion control, and error detection and correction.

IP, on the other hand, is a connectionless protocol that is responsible for addressing and routing packets of data between networks. It provides the foundation for the Internet by defining how packets are addressed, routed, and forwarded between devices on different networks.

Together, TCP and IP form the basis of the Internet Protocol suite, which includes a range of other protocols such as HTTP, FTP, and SMTP, among others. TCP/IP is used to enable communication between devices on the Internet and on most modern computer networks, making it an essential part of modern computing.This is the answer to question 5 of CCNA sample questions set 11.
