Routing & Switching Essentials

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

Which service is provided by an automated attendant feature on a converged network?

• point-to-point video

• call routing

• IT management interface

• video conferencing

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

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

What are the three layers of the switch hierarchical design model? (Choose three.)

• access

• data link

• core

• network access

• distribution

Which cost-effective physical network topology design is recommended when building a three-tier campus network that connects three buildings?​

• bus

• mesh

• extended star

• dual ring

When an appropriate switch form factor for a network is being determined, what should be selected when fault tolerance and bandwidth availability are desired but the budget is limited?

• stackable switch

• non-stackable switch

• fixed configuration switch

• modular switch

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.

Which two characteristics describe a converged network? (Choose two.)

• decreased service calls

• support of voice and video both using the same switch

• separate wiring infrastructure for voice and video traffic

• affordability for small and medium businesses

• cheaper equipment cost

Refer to the exhibit. The PC that is attached to port Fa0/1 is sending a packet that has the destination MAC address of 0050.0fae.299c. Based on the current S1 MAC address table, what will S1 do first when the packet arrives at the switch?

• forward the data to S2

• broadcast an ARP request to all S1 ports except port Fa0/1

• add the MAC address of the PC that is attached to Fa0/1 to the MAC address table

• broadcast the data to all S1 ports and all S2 ports that have attached end devices

• broadcast the data to all S1 ports that have attached end devices, except the Fa0/1 port
