Which PAgP mode combination prevents an Etherchannel from forming? auto/auto desirable/desirable auto/desirable desirable.
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 made, 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 load balance should be set to src-mac.
Refer to the exhibit

08:33:23: %PM-4-ERR_DISABLE: channel-misconfig error detection on Gi0/0, putting Gi0/0 in err-disable state
08:33:23: %PM-4-ERR_DISABLE: channel-misconfig error detection on Gi0/1, putting Gi0/1 in err-disable state
After an engineer configures an EtherChannel between switch SW1 and switch SW2, this error message is logged on switch SW2.
Based on the output from SW1 and the log message received on Switch SW2, what action should the engineer take to resolve this issue?
Configure the same protocol on the EtherChannel on switch SW1 and SW2. Correct the configuration error on interface Gi0/1 on switch SW1. Define the correct port members on the EtherChannel on switch SW1. Correct the configuration error on interface Gi0/0 switch SW1.
Refer to the exhibit.
Company policy restricts VLAN 10 to be allowed only on SW1 and SW2. All other VLANs can be on all three switches. An administrator has noticed that VLAN 10 has propagated to SW3. Which configuration corrects the issue?
SW2(config)#interface gi1/2
SW2(config)#switchport trunk allowed vlan 10
SW1(config)#interface gi1/1
SW1(config)#switchport trunk allowed vlan 1-9,11-4094
SW2(config)#interface gi1/1
SW2(config)#switchport trunk allowed vlan 10
SW2(config)#interface gi1/2
SW2(config)#switchport trunk allowed vlan 1-9,11-4094

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.
