*Refers to the packets in different layers 

• Segment 

• Packet 

• Frame 

• Bucket 

What is a CAN? 

• This is a network type specified for middle size city network. 

• This term is normally used for a network deployment in a university. 

• CAN as Community area network is used to describe a town network. 

• CAN as Client area network is used to describe a home office network. 

What is the advantage from Monomode fiber against Multimode?

• It is in general cheaper than Multimode. 

• It is better for long distances. 

• It is less reliable compare with Multimode. 

• It is environmentally friendly. 

What are the port states in RSTP? 

• Blocking, learning, and forwarding.

• Learning, listening, discarding, and blocking.

• Discarding, learning, and forwarding.

• Blocking, listening, learning, and forwarding .

What is the destination MAC address of a broadcast frame? 

• 00:00:0c:07:ac:01

• ff:ff:ff:ff:ff:ff

• 43:2e:08:00:00:0c

• 00:00:0c:43:2e:08

• ff:ff:ff:ff:ff:ff:ff

Which switch becomes the root bridge?

  32778 0018.184e.3c00 

• Switch 2 
  24586 001a.e3ff.a680 

• Switch 3 
  28682 0022.55cf.cc00

What is the primary goal of Spanning Tree Protocol (STP)? 

• It is a protocol used by routers to interconnect LANs 

• STP is used to prevent and eliminate network loops in Ethernet networks by creating a loop-free logical topology. 

• STP is used to create links between switches and allow them to exchange frames. 

• STP is used to prevent and eliminate network loops between two switches and create a loop-free logical topology. 

How does STP select the Root Bridge in a network? 

• Based on the switch's age

• Randomly

• Based on the Bridge ID

• Based on the switch's IP address

What is the purpose of the STP port state "Blocking"? 

• Forwards data frames

• Learns MAC addresses

• Listens for BPDUs

• Prevents loops by blocking the port

What is the purpose of a VLAN trunk? 

• Connects two separate physical networks

• Carries multiple VLANs over a single link

• Isolates a VLAN from the rest of the network

• Acts as a dedicated VLAN server
