[300-115 SWITCH Free Questions] 300-115 Implementing Cisco IP Switched Networks

1. What is the maximum number of switches that can be stacked using Cisco StackWise?

2. A network engineer wants to add a new switch to an existing switch stack.

Which configuration must be added to the new switch before it can be added to the switch stack?

3. What percentage of bandwidth is reduced when a stack cable is broken?

4. Refer to the exhibit.

Which set of configurations will result in all ports on both switches successfully bundling into an EtherChannel?

5. 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?

6. Refer to the exhibit.

A network engineer wants to analyze all incoming and outgoing packets for an interface that is connected to an access switch.

Which three items must be configured to mirror traffic to a packet sniffer that is connected to the distribution switch? (Choose three.)

7. After an EtherChannel is configured between two Cisco switches, interface port channel 1 is in the down/ down state. Switch A is configured with channel-group 1 mode active, while Switch B is configured with channel-group 1 mode desirable.

Why is the EtherChannel bundle not working?

8. An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the EtherChannel links is being utilized to reach the web server.

What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate web server?

9. Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally: monitor session 2 filter vlan 1 – 8, 39, 52.

What is the result of the implemented command?

10. A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it has several routing neighbor relationships.

What would cause the output to show only the single neighbor?

11. After the implementation of several different types of switches from different vendors, a network engineer notices that directly connected devices that use Cisco Discovery Protocol are not visible.

Which vendor-neutral protocol could be used to resolve this issue?

12. Several new switches have been added to the existing network as VTP clients. All of the new switches have been configured with the same VTP domain, password, and version.

However, VLANs are not passing from the VTP server (existing network) to the VTP clients.

What must be done to fix this?

13. After implementing VTP, the extended VLANs are not being propagated to other VTP switches.

What should be configured for extended VLANs?

14. 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.

15. Refer to the exhibit.

Switch A, B, and C are trunked together and have been properly configured for VTP. Switch B has all VLANs, but Switch C is not receiving traffic from certain VLANs.

What would cause this issue?

A. A VTP authentication mismatch occurred between Switch A and Switch B.

B. The VTP revision number of Switch B is higher than that of Switch A.

C. VTP pruning is configured globally on all switches and it removed VLANs from the trunk interface that is connected to Switch C.

D. The trunk between Switch A and Switch B is misconfigured.

16. 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?

17. An administrator recently configured all ports for rapid transition using PortFast. After testing, it has been determined that several ports are not transitioning as they should.

What is the reason for this?

18. Which technique automatically limits VLAN traffic to only the switches that require it?

19. What effect does the mac address-table aging-time 180 command have on the MAC address- table?

20. While working in the core network building, a technician accidently bumps the fiber connection between two core switches and damages one of the pairs of fiber. As designed, the link was placed into a non-forwarding state due to a fault with UDLD. After the damaged cable was replaced, the link did not recover.

What solution allows the network switch to automatically recover from such an issue?
