CCNA 3 Chapter 7

1. What will a wireless client transmit to discover the available WLAN networks?

probe request

2. Which function is provided by a wireless access point?

converts data from 802.11 to 802.3 frame encapsulation

3. Why is security so important in wireless networks?

Wireless networks broadcast data over a medium that allows easy access.

CCNA 3 Chapter 6

1. Refer to the exhibit. What two conclusions can be drawn from the output that is shown? (Choose two.)

Both of the directly connected routes that are shown will share the same physical interface of the router.
Inter-VLAN routing between hosts on the 172.17.10.0/24 and 172.17.30.0/24 networks is successful on this network.

2. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance?

Implement a router-on-a-stick configuration.

3. What is important to consider while configuring the subinterfaces of a router when implementing inter-VLAN routing?

The IP address of each subinterface must be the default gateway address for each VLAN subnet.

CCNA 3 Chapter 5

1. What three link types have been defined for Rapid Spanning-Tree Protocol? (Choose three.)

shared
edge-type
point-to-point

2. What Rapid Spanning Tree Protocol (RSTP) role is assigned to the forwarding port elected for every switched Ethernet LAN segment?

designated

3. How can a network administrator influence which STP switch becomes the root bridge?

Set the switch priority to a smaller value than that of the other switches in the network.

CCNA 3 Chapter 4

1. Which statement is true when VTP is configured on a switched network that incorporates VLANs?

VTP dynamically communicates VLAN changes to all switches in the same VTP domain.

2. What are two features of VTP client mode operation? (Choose two.)

unable to add VLANs
can forward VLAN information to other switches in the same VTP domain

3. Which three VTP parameters must be identical on all switches to participate in the same VTP domain? (Choose three.)

domain name
domain password
version number

CCNA 3 Chapter 3

1. What switch port modes will allow a switch to successfully form a trunking link if the neighboring switch port is in "dynamic desirable" mode?

on, auto, or dynamic desirable mode

2. Refer to the exhibit. Computer 1 sends a frame to computer 4. On which links along the path between computer 1 and computer 4 will a VLAN ID tag be included with the frame?

C, E

CCNA 3 Chapter 2

1. Which two statements about Layer 2 Ethernet switches are true? (Choose two.)

Layer 2 switches have multiple collision domains.
Layer 2 switches can send traffic based on the destination MAC address.

2. Which command line interface (CLI) mode allows users to configure switch parameters, such as the hostname and password?

global configuration mode

CCNA 3 Chapter 1

1. A network administrator is selecting a switch that will operate at the network core. Which three features should the switch support for optimum network performance and reliability? (Choose three.)

10 Gigabit Ethernet
quality of service (QoS)
hot-swappable hardware

2. Refer to the exhibit. Beginning with HR servers and workstations, a network engineer is designing a new security structure for the network. Which set of policies adheres to the hierarchical network model design principles?

Configure port security options on S1. Use Layer 3 access control features on D1 and D2 to limit access to the HR servers to just the HR subnet.
