Question 1 of 15
1. Question
1 pointsWhich service is provided by an automated attendant feature on a converged network?Correct
Incorrect
The automated attendant feature increases the speed of voice services by routing calls directly to individuals or departments. Point-to-point video and video conferencing describe video services on a converged network. An IT management interface is part of a converged network solution that allows IT personnel to facilitate moves, adds, and changes through a centralized application.

2. Question
1 pointsRefer to the exhibit. Fill in the blank.
How many broadcast domains are in the topology?
Correct
Incorrect
Adding additional switches and devices increases the broadcast domain. A broadcast sent from any PC is received by the three other PCs.

Question 3 of 15
3. Question
1 pointsWhen 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?Correct
Incorrect
Stackable switches provide fault tolerance and bandwidth availability by using special cables between switches and are less costly to implement than modular switches. A non-stackable switch does not provide these features. A fixed configuration switch is a single switch that does not support features beyond those that originally came with it. A modular switch usually provides fault tolerance and features for bandwidth availability but is rather costly to implement.

4. Question
1 pointsWhen 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?
Correct
Incorrect
A modular switch provides fault tolerance and features for bandwidth availability and future expansion by using line cards but is rather costly to implement. Stackable switches provide fault tolerance and bandwidth availability by using special cables between the switches and are less costly to implement than modular switches. A nonstackable switch does not provide these features. A fixed configuration switch is a single switch that does not support features beyond those that originally came with it.

5. Question
1 pointsWhich statement is true about broadcast and collision domains?Correct
Incorrect
A switch that receives a broadcast frame will forward the frame out all other interfaces, including interfaces that connect to other switches. These switches will also perform the same forwarding action. By adding more switches to the network, the size of the broadcast domain increases.

6. Question
1 pointsWhich function is supplied by the access layer in a three-layer network design?Correct
Incorrect
The main purpose of devices in the access layer is to supply network access to end users. Distribution layer devices provide services such as routing and policy functions. The core layer provides high-speed backbone connectivity.

7. Question
1 pointsWhich switching method describes a switch that transfers a frame as soon as the destination MAC address is read?Correct
Incorrect

Question 8 of 15
8. Question
1 pointsWhich option correctly describes a switching method?Correct
Incorrect
Store-and-forward switching performs an error check on an incoming frame after receiving the entire frame on the ingress port. Switches which use this method have the flexibility to support any mix of Ethernet speeds. The cut-through method begins the forwarding process after the destination MAC address of an incoming frame is looked up and the egress port has been determined.

Question 9 of 15
9. Question
2 pointsRefer to the exhibit. A switch receives a Layer 2 frame that contains a source MAC address of 000b.a023.c501 and a destination MAC address of 0050.0fae.75aa. Place the switch steps in the order they occur. (Not all options are used.)
Sort elements
- The switch adds the source MAC address to the MAC address table.
- Because the destination is not known, the switch forwards the frame out all ports except the port through which the frame arrived.
- The switch drops the frame.
-
occurs first
-
occurs second
Correct
Incorrect
The first step a switch does when processing a frame is to see if the source MAC address is in the MAC address table. If the address is not there, the switch adds it. The switch then examines the destination MAC address and compares it to the MAC address table. If the address is in the table, the switch forwards the frame out the corresponding port. If the address is missing from the table, the switch will forward the frame to all ports except the port through which the frame arrived.

Question 10 of 15
10. Question
1 pointsWhich impact does adding a Layer 2 switch have on a network?Correct
Incorrect
Adding a Layer 2 switch to a network increases the number of collision domains and increases the size of the broadcast domain. Layer 2 switches do not decrease the amount of broadcast traffic, do not increase the amount of network collisions and do not increase the number of dropped frames.

Question 11 of 15
11. Question
3 pointsWhat are the three layers of the switch hierarchical design model? (Choose three.)Correct
Incorrect
The access layer is the lowest layer and it provides network access to users. The distribution layer has many functions, but it aggregates data from the access layer, provides filtering, policy control, and sets Layer 3 routing boundaries. The core layer provides high speed connectivity.

12. Question
1 pointsWhich cost-effective physical network topology design is recommended when building a three-tier campus network that connects three buildings?Correct
Incorrect
For efficiency, scalability, and cost-effectiveness, building an extended star topology from a centralized site to all other campus sites is recommended. A mesh topology is much more expensive, and bus and dual ring topologies are more difficult to troubleshoot and maintain.

Question 13 of 15
13. Question
1 pointsWhen would a network designer be concerned with RUs?Correct
Incorrect
A rack unit or RU is a specific measurement related to the height of the switch. A switch with a 1 RU rating is smaller than a 2 RU switch. Port density measures the number of ports on a switch. Modularity influences the number of available line cards. Port speed measures the number of bits per second that can flow through a given port.

Question 14 of 15
14. Question
1 pointsRefer 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?
Correct
Incorrect
The first step a switch does when processing a frame is to see if the source MAC address is in the MAC address table. If the address is not there, the switch adds it. The switch then examines the destination MAC address and compares it to the MAC address table. If the address is in the table, the switch forwards the frame out the corresponding port. If the address is missing from the table, the switch will broadcast the frame to all ports except the port through which the frame arrived.

Question 15 of 15
15. Question
2 pointsWhich two characteristics describe a converged network? (Choose two.)Correct
Incorrect
Converged networks have traditional user traffic as well as digitized voice and video traffic that once required separate networks. Now, instead of separate groups managing separate networks, one group of personnel can manage the network.
