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.

4. Refer to the exhibit. What can be determined from the output shown?

The priority was statically configured to identify the root.

5. Which three statements are accurate regarding RSTP and STP? (Choose three.)

Both RSTP and STP use the portfast command to allow ports to immediately transition to forwarding state.
Configuration commands to establish primary and secondary root bridges are identical for STP and RSTP.
Because of the format of the BPDU packet, RSTP is backward compatible ... Читать дальше »

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

4. What does a client mode switch in a VTP management domain do when it receives a summary advertisement with a revision number higher than its current revision number?

It issues an advertisement request for new VLAN information.

5. Refer to the exhibit. The switches in the exhibit are connected with trunks within the same VTP management domain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does not ... Читать дальше »

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

3. Refer to the exhibit. The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?

The trunk cannot be negotiated with both ends set to auto.

4. What must the network administrator do to remove Fast Ethernet port fa0/1 from VLAN 2 and assign it to VLAN 3?

Enter the switchport access vlan 3 command in interface configuration mode.

5. Which two statements describe the benefits of VLANs? (Choose two.)

VLANs improve network security by isolating users that have access to sensitive data and applications.
VLANs divide a network into ... Читать дальше »

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

3. Which two statements are true about EXEC mode passwords? (Choose two.)

The enable secret password command provides better security than the enable password.
The enable password and enable secret password protect access to privileged EXEC mode.

4. Where is the startup configuration stored?

NVRAM

5. Refer to the exhibit. What action does SW1 take on a frame sent from PC_A to PC_C if the MAC address table of SW1 is empty?

SW1 floods the frame on all ports on SW1, except port Fa0/1.

6. Refer to the exhibit. Which hosts will receive a broadcast frame sent from Host A?

hosts A, ... Читать дальше »

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.

3. Which layer of the OSI model does an access layer LAN switch use to make a forwarding decision?

Layer 2

4. What is the likely impact of moving a conventional company architecture to a completely converged network?

A shared infrastructure is created resulting in a single network to manage.

5. Configuring communi ... Читать дальше »
