Which VLAN must be trunked back to the Clean Access Server from the access switch?

  1. authentication VLAN
  2. user VLAN
  3. untrusted VLAN
  4. management VLAN

Answer(s): D



Refer to the exhibit.




A customer runs OSPF with Area 5 between its aggregation router and an internal router When a network change occurs in the backbone. Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5 You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area How can you accomplish this task*?

  1. Increase the bandwidth on the connection between Router A and Router B
  2. Implement LSA filtering ontheAB, allowing summary routes and preventing more specific routes into Area 5
  3. Create a virtual link to Area 0 from Router B to the ABR
  4. Turn on LSA throttling on all devices in Area 5
  5. Set Area 5 to stubby at the ABR anyway

Answer(s): B
