Exam 300-115: Question 6 - Image 1

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.)

A monitor session on the distribution switch with a physical interface as the source and the remote SPAN VLAN as the destination

A remote SPAN VLAN on the distribution and access layer switch

A monitor session on the access switch with a physical interface source and the remote SPAN VLAN as the destination

A monitor session on the distribution switch with a remote SPAN VLAN as the source and physical interface as the destination

A monitor session on the access switch with a remote SPAN VLAN source and the physical interface as the destination

A monitor session on the distribution switch with a physical interface as the source and a physical interface as the destination

Correct Answer: B, C, D

Question 7 of 805

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?

The switches are using mismatched EtherChannel negotiation modes.

The switch ports are not configured in trunking mode.

LACP priority must be configured on both switches.

The channel group identifier must be different for Switch A and Switch B.

Correct Answer: A

Here we have a situation where one switch is using active mode, which is an LACP mode, and the other is using desirable, which is a PAGP mode. You can not mix the LACP and PAGP protocols to form an etherchannel. Here is a summary of the various etherchannel modes:

Question 8 of 805

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?

Enable Cisco Express Forwarding to allow for more effective traffic sharing over the EtherChannel bundle.

Adjust the EtherChannel load-balancing method based on destination IP addresses.

Disable spanning tree on all interfaces that are participating in the EtherChannel bundle.

Use link-state tracking to allow for improved load balancing of traffic upon link failure to the server.

Adjust the EtherChannel load-balancing method based on source IP addresses.

Correct Answer: E

Question 9 of 805

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?

All VLAN traffic is sent to the SPAN destination interface.

Traffic from VLAN 4 is not sent to the SPAN destination interface.

Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.

The trunk’s native VLAN must be changed to something other than VLAN 1.

Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.

Correct Answer: E

Question 10 of 805

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?

The routers are connected via a Layer 2 switch.

IP routing is disabled on neighboring devices.

Cisco Express Forwarding is enabled locally.

Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.

Correct Answer: A
