Refer to the exhibit. Which action do the switches take on the trunk link?

  1. The trunk does not form, and the ports go into an err-disabled status.
  2. The trunk forms, but the mismatched native VLANs are merged into a single broadcast domain.
  3. The trunk forms, but VLAN 99 and VLAN 999 are in a shutdown state.
  4. The trunk does not form, but VLAN 99 and VLAN 999 are allowed to traverse the link.

Answer(s): B

Explanation:

The trunk still forms with mismatched native VLANs and the traffic can actually flow between mismatched switches. But it is absolutely necessary that the native VLANs on both ends of a trunk link match; otherwise a native VLAN mismatch occurs, causing the two VLANs to effectively merge. For example, with the above configuration, SW1 would send untagged frames for VLAN 999. SW2 receives them but would think they are for VLAN 99 so we can say these two VLANs are merged.



A network engineer must configure two new subnets using the address block 10.70.128.0/19 to meet these requirements:
-The first subnet must support 24 hosts.
-The second subnet must support 472 hosts.
-Both subnets must use the longest subnet mask possible from the address block.

Which two configurations must be used to configure the new subnets and meet a requirement to use the first available address in each subnet for the router interfaces? (Choose two.)

  1. interface vlan 1148 ip address 10.70.148.1 255.255.254.0
  2. interface vlan 3002 ip address 10.70.147.17 255.255.255.224
  3. interface vlan 4722 ip address 10.70.133.17 255.255.255.192
  4. interface vlan 1234 ip address 10.70.159.1 255.255.254.0
  5. interface vlan 155 ip address 10.70.155.65 255.255.255.224

Answer(s): A,E



Refer to the exhibit. An administrator must configure interfaces Gi1/1 and Gi1/3 on switch SW11. PC-1 and PC-2 must be placed in the Data VLAN, and Phone-1 must be placed in the Voice VLAN. Which configuration meets these requirements?

  2. interface gigabitethernet1/1 switchport mode access switchport access vlan 8 ! interface gigabitethernet1/3 switchport mode trunk switchport trunk vlan 8 switchport voice vlan 9
  3. interface gigabitethernet1/1 switchport mode access switchport access vlan 9 ! interface gigabitethernet1/3 switchport mode trunk switchport trunk vlan 8 switchport trunk vlan 9
  4. interface gigabitethernet1/1 switchport mode access switchport access vlan 8 ! interface gigabitethernet1/3 switchport mode access switchport voice vlan 8 switchport access vlan 9

Answer(s): A
