CCNA – Switch Questions

Question 1

Explanation

The MAC address of 00b0.d056.efa4 has not been learned in its MAC address table so Switch-1 will broadcast the frame out all of its ports except the port from which the data originated.

Question 2

Explanation

To remote access to SwitchB, it must have a management IP address on a VLAN on that switch. Traditionally, we often use VLAN 1 as the management VLAN (but in fact it is not secure).

In the exhibit, we can recognize that the Management Workstation is in a different subnet from the SwitchB. For intersubnetwork communication to occur, you must configure at least one default gateway. This default gateway is used to forward traffic originating from the switch only, not to forward traffic sent by devices connected to the switch.

Question 3

Question 4

Explanation

The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.

Question 5

Question 6

Question 7

Question 8

Question 9

Explanation

From the “show mac address-table” output, we see FastEthernet0/1 can receive traffic from multiple VLANs -> it is configured as a trunk. Also from the “show cdp neighbors” output, we see Fa0/1 of this switch is connecting to Switch2 so it is configured as a trunk.

There are two MAC addresses learned from FastEthernet0/5 while FastEthernet0/5 is not configured as trunk (only Fa0/2 & Fa0/3 are configured as trunk links) -> a hub is used on this port.

Question 10

Explanation

Host A (172.19.1.1) and the management IP address of the Switch (172.19.1.250) are in the same subnet so telnet from host A to the switch can be successful even if a default gateway is not set on host A.

But host B (172.19.32.2) and the management IP address of the Switch (172.19.1.250) are not in the same subnet so host B needs a default gateway to telnet to the switch. The default gateway on host B should be 172.19.32.254. But in fact host B can ping to host A and host C so host b must have been configured with the default gateway.

The switch needs a default gateway so that it can send data to outside (reply to host B in this case). And we have to assign it with the command:
Switch(config)#ip default-gateway 172.19.1.254

    I passed the CCNA Collaboration 210-060 exam with 96%. This dumps http://www.grades4sure.com/210-060-exam-questions.html is valid and all my questions are from this. Need to notice that there is slight change of the answer orders, so be awarded. Read the book and then use these dumps as an aid. Good luck to you all.

    Question 1’s answer doesn’t make sense. If the switch receives a frame and doesn’t have the MAC in it’s table, it should ARP for it first. So I think D should be the correct answer
