Q1. Which command is needed to enable DHCP snooping if a switchport is connected to a DHCP server?
A. ip dhcp snooping trust
B. ip dhcp snooping
C. ip dhcp trust
D. ip dhcp snooping information
Answer: A
Q2. 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
Q3. After implementing VTP, the extended VLANs are not being propagated to other VTP switches. What should be configured for extended VLANs?
A. VTP does not support extended VLANs and should be manually added to all switches.
B. Enable VTP version 3, which supports extended VLAN propagation.
C. VTP authentication is required when using extended VLANs because of their ability to cause network instability.
D. Ensure that all switches run the same Cisco IOS version. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use.
Answer: B
Q4. Which statement describes what happens when a port configured with root guard receives a superior BPDU?
A. The port goes into errdisabled state and stops forwarding traffic.
B. The port goes into BPDU-inconsistent state and stops forwarding traffic.
C. The port goes into loop-inconsistent state and stops forwarding traffic.
D. The port goes into root-inconsistent state and stops forwarding traffic.
Answer: D
Q5. Refer to the exhibit.
Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C receives VLAN information from the VTP server Switch A, but Switch B does not receive any VLAN information. What is the most probable cause of this behavior?
A. Switch B is configured in transparent mode.
B. Switch B is configured with an access port to Switch A, while Switch C is configured with a trunk port to Switch B.
C. The VTP revision number of the Switch B is higher than that of Switch A.
D. The trunk between Switch A and Switch B is misconfigured.
Answer: A
Q6. The network manager has requested that several new VLANs (VLAN 10, 20, and 30) are allowed to traverse the switch trunk interface. After the command switchport trunk allowed vlan 10,20,30 is issued, all other existing VLANs no longer pass traffic over the trunk. What is the root cause of the problem?
A. The command effectively removed all other working VLANs and replaced them with the new VLANs.
B. VTP pruning removed all unused VLANs.
C. ISL was unable to encapsulate more than the already permitted VLANs across the trunk.
D. Allowing additional VLANs across the trunk introduced a loop in the network.
Answer: A
Q7. Which switch feature determines validity based on IP-to-MAC address bindings that are stored in a trusted database?
A. Dynamic ARP Inspection
B. storm control
C. VTP pruning
D. DHCP snooping
Answer: A
Q8. Which SDM template is the most appropriate for a Layer 2 switch that provides connectivity to a large number of clients?
A. VLAN
B. default
C. access
D. routing
Answer: A
Q9. while doing network discovery using Cisco Discovery Protocol, it is found that rapid error tracking is not currently enabled. Which option must be enabled to allow for enhanced reporting mechanisms using Cisco Discovery Protocol?
A. Cisco Discovery Protocol version 2
B. Cisco IOS Embedded Event Manager
C. logging buffered
D. Cisco Discovery Protocol source interface
E. Cisco Discovery Protocol logging options
Answer: A
Q10. Refer to the exhibit.
What is the result of the SPAN configuration on a Cisco switch?
A. Configure a SPAN session to monitor the received traffic on interface g0/4 only for VLAN 3.
B. Configure a SPAN session to monitor the received traffic on interface g0/4 for all VLANs except VLAN 3.
C. Configure a SPAN session to monitor the received traffic on interface g0/5 only for VLAN 3.
D. Configure a SPAN session to monitor the received traffic on interface g0/5 for all VLANs except VLAN 3.
Answer: A
