A. Rapid Spanning-Tree

B. Spanning-Tree Timers

C. Spanning-Tree FastPort

D. Spanning-Tree PortFast

E. Spanning-Tree Fast Forward

Answer: D

B. switch# show spanning-tree bridge

C. switch# show spanning-tree brief

D. switch# show spanning-tree summary

E. switch# show spanning-tree vlan 10 brief

Answer: A

Q3. Refer to the exhibit.

The network switches for two companies have been connected and manually configured for the required VLANs, but users in company A are not able to access network resources in company B when DTP is enabled. Which action resolves this problem?

A. Delete vlan.dat and ensure that the switch with lowest MAC address is the VTP server.

B. Disable DTP and document the VTP domain mismatch.

C. Manually force trunking with switchport mode trunk on both switches.

D. Enable the company B switch with the vtp mode server command.

Answer: C

Q4. Which statement about using EtherChannel on Cisco IOS switches is true?

A. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

B. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

C. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel.

D. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 10 Gbps only for Gigabit EtherChannel.

Answer: A

Q5. Which private VLAN can have only one VLAN and be a secondary VLAN that carries unidirectional traffic upstream from the hosts toward the promiscuous ports and the gateway?

A. isolated VLAN

B. primary VLAN

C. community VLAN

D. promiscuous VLAN

Answer: A

Q6. Ferris Plastics, Inc. is a medium sized company, with an enterprise network (access, distribution and core switches) that provides LAN connectivity from user PCs to corporate servers. The distribution switches are configured to use HSRP to provide a high availability solution.

• DSW1 -primary device for VLAN 101 VLAN 102 and VLAN 105

• DSW2 - primary device for VLAN 103 and VLAN 104

• A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to release its status as the primary device, unless GigabitEthernet1/0/1 on backup device has also failed.

Troubleshooting has identified several issues. Currently all interfaces are up. Using the running configurations and show commands, you have been asked to investigate and respond to the following question.

During routine maintenance, it became necessary to shut down the GigabitEthernet1/0/1 interface on DSW1 and DSW2. All other interfaces were up. During this time, DSW1 became the active router for the VLAN 104HSRP group. As related to the VLAN 104HSRP group, what can to be done to make the group function properly?

A. On DSW1, disable preempt.

B. On DSW2 decrease the priority value to a value less than 150.

C. On DSW1, increase the decrement value in the track command to a value greater than 6.

D. On DSW1, decrease the decrement value in the track command to a value less than 1.

Answer: C

Q7. A network engineer is installing a switch for temporary workers to connect to. The engineer does not want this switch participating in Spanning Tree with the rest of the network; however, end user connectivity is still required. Which spanning-tree feature accomplishes this?

A. BPDUblock

B. BPDUfilter

C. BPDUignore

D. BPDUguard

E. BPDUdisable

Answer: B

Q8. A network engineer configures port security and 802.1x on the same interface. Which option describes what this configuration allows?

C. It allows 802.1x to secure the MAC address that port security authenticates.

D. It allows 802.1x to secure the IP address that port security authenticates.

Answer: A
