Nt1310 Unit 1 Question Paper
1.Which statement is true about broadcast and collision domains?
Adding a router to a network will increase the size of the collision domain. The size of the collision domain can be reduced by adding hubs to a network. The more interfaces a router has the larger the resulting broadcast domain. Adding a switch to a network will increase the size of the broadcast domain.
2. Which switching method describes a switch that transfers a frame as soon as the destination MAC address is read? fragment-free cut-through store-and-forward latency forwarding
3. Which cost-effective physical network topology design is recommended when building a three-tier campus network that connects three buildings? bus mesh extended star …show more content…
Which option correctly describes a switching method? cut-through: makes a forwarding decision after receiving the entire frame store-and-forward: forwards the frame immediately after examining its destination MAC address cut-through: provides the flexibility to support any mix of Ethernet speeds store-and-forward: ensures that the frame is free of physical and data-link errors
6. Which function is supplied by the access layer in a three-layer network design? high-speed connectivity routing application of policies network access backbone connectivity
7. When the appropriate switch form factor for a network is being determined, what type of switch should be selected when future expansion is important and cost is not a limiting factor? stackable switch 1 rack unit switch fixed configuration switch modular switch
8. What are the three layers of the switch hierarchical design model? (Choose three.) access data link core network access enterprise distribution
9. Which two statements about Layer 2 Ethernet switches are true? (Choose two.) Layer 2 switches prevent broadcasts. Layer 2 switches have multiple collision
