Q17. After the recent upgrade of the switching infrastructure, the network engineer notices that the port roles that were once "blocking" are now defined as "alternate" and "backup." What is the reason for this change?

A. The new switches are using RSTP instead of legacy IEEE 802.1D STP.

B. IEEE 802.1D STP and PortFast have been configured by default on all newly implemented Cisco Catalyst switches.

C. The administrator has defined the switch as the root in the STP domain.

D. The port roles have been adjusted based on the interface bandwidth and timers of the new Cisco Catalyst switches.

Q18. Interfaces are assigned to a VLAN, and then the VLAN is deleted. Which state are these interfaces in after the VLAN is deleted?

A. They remain up, but they are reassigned to the default VLAN.

B. They go down until they are reassigned to a VLAN.

C. They go down, but they are reassigned to the default VLAN.

D. They remain up, but they are reassigned to the native VLAN.

Q19. What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU?

A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.

B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.

C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU.

D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.

Q20. an EtherChannel configured and one of the port was used as SPAN destination. What will be the result?

A. the etherchannel will not be operational because the port cannot be used as SPAN destination

B. etherchannel will discard the port used

C. the etherchannel will shutdown

Q21. After reviewing UDLD status on switch ports, an engineer notices that the." Which statement describes what this indicates about the status of the port?

A. The port is fully operational and no known issues are detected.

B. The bidirectional status of "unknown" indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor.

C. UDLD moved into aggressive mode after inconsistent acknowledgements were detected.

D. The UDLD port is placed in the "unknown" state for 5 seconds until the next UDLD packet is received on the interface.

Q22. Refer to the exhibit.

How can the traffic that is mirrored out the GigabitEthernet0/48 port be limited to only traffic that is received or transmitted in VLAN 10 on the GigabitEthernet0/1 port?

A. Change the configuration for GigabitEthernet0/48 so that it is a member of VLAN 10.

B. Add an access list to GigabitEthernet0/48 to filter out traffic that is not in VLAN 10.

C. Apply the monitor session filter globally to allow only traffic from VLAN 10.

D. Change the monitor session source to VLAN 10 instead of the physical interface.

Q23. 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.

u2022 DSW1 -primary device for VLAN 101 VLAN 102 and VLAN 105

u2022 DSW2 - primary device for VLAN 103 and VLAN 104

u2022 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.

Q24. You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.

You are adding new VLANs. VLAN500 and VLAN600 to the topology in such way that you need to configure SW1 as primary root for VLAN 500 and secondary for VLAN 600 and SW2 as primary root for VLAN 600 and secondary for VLAN 500. Which configuration step is valid?

A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2

B. Configure VLAN 500 and VLAN 600 on SW1 only

C. Configure VLAN 500 and VLAN 600 on SW2 only

D. Configure VLAN 500 and VLAN 600 on SW1 ,SW2 and SW4

E. On SW2; configure vtp mode as off and configure VLAN 500 and VLAN 600; configure back to vtp server mode.

Q25. Refer to the exhibit.

The users in an engineering department that connect to the same access switch cannot access the network. The network engineer found that the engineering VLAN is missing

from the database. Which action resolves this problem?

A. Disable VTP pruning and disable 802.1q.

B. Update the VTP revision number.

C. Change VTP mode to server and enable 802.1q.

D. Enable VTP pruning and disable 802.1q.
