4. Examine the concept of VLAN pruning and its significance in large-scale networks. Provide a practical example illustrating when VLAN pruning is crucial.

VLAN pruning is the process of limiting the propagation of broadcast traffic in a VLAN to only those switches and ports where the traffic is required. In large-scale networks, VLAN pruning optimizes network bandwidth and reduces unnecessary broadcast traffic. An example scenario is a campus network with multiple buildings, where each building has its VLAN, and VLAN pruning ensures broadcast traffic is confined to each building's switches only.

VLAN pruning is only relevant in small networks with limited devices. It is not significant in large-scale networks.

VLAN pruning is primarily used for wireless networks. It optimizes bandwidth by restricting broadcast traffic to specific wireless devices.

VLAN pruning is essential for secure networks but not for optimizing bandwidth in large-scale scenarios.

5. What is the difference between a hub and a switch?

A hub operates at the application layer, while a switch operates at the network layer

A hub broadcasts data to all connected devices, while a switch forwards data only to the intended device

A hub has more ports than a switch

A hub supports wireless connections, while a switch does not

6. What is VLAN short for?

Virtual Layered Area Network

Variable Length Addressing

Virtual Local Area Network

Visual LAN

7. What is the main advantage of using dynamic routing protocols?

They are simpler to configure

They provide better security

They automatically adapt to changes in the network topology

They have a lower cost of implementation

8. What is the primary purpose of a router in a computer network?

Amplifying network signals

Filtering incoming network traffic

Connecting multiple local networks

Broadcasting data to all devices on a network

9. Discuss the concept of VLSM (Variable Length Subnet Masking) and its advantages in optimizing IP address allocation. Provide a practical example where VLSM is crucial for efficient address utilization.

VLSM allows for the allocation of IP addresses based on varying subnet mask lengths, optimizing address space usage. In scenarios such as an enterprise network with multiple departments of different sizes, VLSM ensures efficient IP address utilization by assigning smaller subnets to departments with fewer devices and larger subnets to departments with more devices.

VLSM is only relevant in small networks with a limited number of devices. It does not significantly impact IP address allocation efficiency in larger networks.

VLSM is designed for wireless networks to manage address allocation for mobile devices. It is not necessary in wired networks.

VLSM is primarily used for security purposes in networks. It does not provide advantages in optimizing IP address allocation.

10. What does IP stand for in the context of networking?

Internet Protocol

Internal Processing

Interconnect Point

Intranet Provider

11. What is the purpose of the RIP (Routing Information Protocol) in routing?

To secure remote access to network devices

To provide secure email communication

To dynamically update and share routing tables between routers

To filter network traffic based on specified criteria

12. What is the purpose of ARP (Address Resolution Protocol)?

To convert IP addresses to MAC addresses

To encrypt network traffic

To authenticate users

To compress data packets

13. Which command is used to check the routing table in a Cisco router?

ipconfig

route print

show ip route

netstat -r

14. What is the purpose of the STP (Spanning Tree Protocol) in a network?

To prevent broadcast storms

To ensure redundant links do not create loops

To encrypt data during transmission

To assign IP addresses dynamically

15. In networking, what is the purpose of a subnet mask?

Encrypting data transmissions

Identifying network devices

Dividing an IP address into network and host portions

Determining the speed of network connections

16. What is the purpose of a VLAN (Virtual Local Area Network) in networking?

Increasing the speed of data transmission

Segmenting a physical network into multiple logical networks

Providing encryption for network traffic

Connecting two separate physical networks

17. What is a subnet mask used for?

To identify the network portion of an IP address

To hide a network from unauthorized access

To define the default gateway

To encrypt data transmission

18. Explain the purpose of BGP (Border Gateway Protocol) in detail, and discuss a scenario where it is the preferred routing protocol.

BGP is used to connect different autonomous systems and make routing decisions based on policies. It's preferred in scenarios where complex policy-based routing and inter-domain routing are required.

BGP is a simple protocol for small networks and is preferred for its ease of configuration. It excels in scenarios with a limited number of routers.

BGP is designed for local area networks and is preferred for its speed in large-scale networks. It is ideal for scenarios where rapid data transfer is crucial.

BGP is primarily used for wireless networks and is preferred for its ability to handle dynamic changes. It excels in scenarios where network topology frequently changes.

19. Explain the concept of MPLS (Multiprotocol Label Switching) and its advantages in improving network performance and efficiency. Provide a use case where MPLS is particularly beneficial.

MPLS is a protocol that enhances network performance and efficiency by assigning labels to packets. This allows routers to make forwarding decisions based on labels rather than complex routing tables. MPLS is beneficial in scenarios such as large-scale service provider networks, where it improves the speed and reliability of data transfer by optimizing packet forwarding.

MPLS is primarily used for security purposes in networks. It does not significantly impact performance or efficiency.

MPLS is designed for small networks with minimal traffic. It is not necessary in large-scale networks.

MPLS is only relevant in networks with predominantly wireless connections. It does not provide advantages in wired networks.

20. Elaborate on the differences between static routing and dynamic routing. In what scenarios would one be preferred over the other?

Static routing involves manually configuring the routing table, while dynamic routing protocols automatically update the routing table based on network changes. Static routing is preferred in small networks with a stable topology, while dynamic routing is suitable for large, dynamic networks where changes occur frequently.

Static routing is more secure than dynamic routing. It is always the preferred choice, regardless of network size.

Dynamic routing protocols are more straightforward to configure than static routing. They are preferred for their simplicity in all scenarios.

Static routing is only used for specialized applications and is not recommended for general network use.
