Demo Questions
Question 1
Which PAgP mode combination prevents an Etherchannel from forming?
- auto/auto
- desirable/desirable
- auto/desirable
- desirable
Correct answer: A
Explanation:
There are two PAgP modes:Auto Responds to PAgP messages but does not aggressively negotiate a PAgP EtherChannel. A channel is formed only if the port on the other end is set to Desirable. This is the default mode. Desirable Port actively negotiates channeling status with the interface on the other end of the link. A channel is formed if the other side is Auto or Desirable. The table below lists if an EtherChannel will be formed or not for PAgP:PAgP Desirable Auto Desirable Yes Yes Auto Yes No There are two PAgP modes:

The table below lists if an EtherChannel will be formed or not for PAgP:
PAgP Desirable Auto
Desirable Yes Yes
Auto Yes No
Question 2
Refer to the exhibit. A port channel is configured between SW2 and SW3. SW2 is not running Cisco operating system. When all physical connections are mode, the port channel does not establish. Based on the configuration excerpt of SW3, what is the cause of the problem?
interface gi1/2
channel-group 30 mode desirable
port-channel load-balance src-ip
interface gi1/3
channel-group 30 mode desirable
port-channel load-balance src-ip
interface PortChannel 30
switchport mode trunk
switchport encapsulation dot1q
switchport trunk allowed vlan 10-100
- The port channel on SW2 is using an incompatible protocol
- The port-channel trunk is not allowing the native VLAN
- The port-channel should be set to auto
- The port-channel interface lead balance should be set to src-mac
Correct answer: A
Explanation:
The Cisco switch was configured with PAgP, which is a Cisco proprietary protocol so non-Cisco switch could not communicate. The Cisco switch was configured with PAgP, which is a Cisco proprietary protocol so non-Cisco switch could not communicate.
Question 3
Refer to exhibit. VLANs 50 and 60 exist on the trunk links between all switches. All access ports on SW3 are configured for VLAN 50 and SW1 is the VTP server. Which command ensures that SW3 receives frames only from VLAN 50?
- SW1 (config)#vtp pruning
- SW3(config)#vtp mode transparent
- SW2(config)=vtp pruning
- SW1(config)>vtp mode transparent
Correct answer: A
Explanation:
SW3 does not have VLAN 60 so it should not receive traffic for this VLAN (sent from SW2). Therefore we should configure VTP Pruning on SW3 so that SW2 does not forward VLAN 60 traffic to SW3. SW3 does not have VLAN 60 so it should not receive traffic for this VLAN (sent from SW2). Therefore we should configure VTP Pruning on SW3 so that SW2 does not forward VLAN 60 traffic to SW3.
