Question 1

Layer 2 switching uses which of the following values to forward data?

Accepted Answer

MAC address

Answer

Explanation:
Layer 2 switching uses MAC addresses to forward data. MAC addresses are unique identifiers assigned to network interface cards (NICs) at the factory. Layer 2 switches use these addresses to determine the destination of the data and forward it to the appropriate device on the local network. IP addresses, IPX addresses, RIP addresses, and UDP ports are all used in different layers of the network stack and are not directly used by layer 2 switching

Question 2

Which of the following does a multilayer switch perform?

Accepted Answer

All of the above.

Answer

Explanation:
A multilayer switch performs all of the mentioned tasks. It is capable of forwarding data packets based on MAC addresses, IP addresses, and UDP/TCP port numbers. This allows the switch to efficiently route traffic at both the data link layer and network layer, making it a versatile networking device.

Question 3

What does the 20/80 rule of networking state? (Pick one.)

Accepted Answer

Twenty percent of the traffic on a network segment stays local, whereas 80 percent of it travels across the network.

Answer

Explanation:
The 20/80 rule of networking states that twenty percent of the traffic on a network segment stays local, whereas 80 percent of it travels across the network. This means that only a small portion of the network traffic remains within a specific segment, while the majority of it is transmitted across different segments or even outside of the network. This rule highlights the importance of efficient network design and management to ensure smooth and effective data transmission.

Question 4

Where does a collision domain exist in a switched network?

Accepted Answer

On a single switch port

Answer

Explanation:
A collision domain exists on a single switch port in a switched network. In a switched network, each switch port operates as an individual collision domain. This means that when data is transmitted on a switch port, it does not collide with data transmitted on other switch ports. Switches use MAC address tables to forward data only to the intended destination port, effectively isolating each port and creating separate collision domains. This allows for efficient and simultaneous communication between devices connected to different switch ports.

Question 5

Where does a broadcast domain exist in a switched network?

Accepted Answer

On a single VLAN

Answer

Explanation:
A broadcast domain exists on a single VLAN in a switched network. A VLAN (Virtual Local Area Network) is a logical grouping of devices that are connected to the same network and can communicate with each other as if they were on the same physical network. In a switched network, each VLAN is isolated from others, creating separate broadcast domains. This means that broadcast traffic, such as ARP requests or DHCP requests, is only forwarded within the same VLAN and does not cross over to other VLANs. Therefore, a broadcast domain exists within a single VLAN in a switched network.
