Nokia Nuage Networks Professional - Software Defined Datacenter (NNP SD-DC) 4A0-N01 Questions & Answers

• Question 11:

  Refer to the diagram. Which statement is describing a step incorrectly?

  

  A. Step a, which consists of defining network domain and policy templates on VSD, must be performed first in all situations.

  B. Step d, which refers to the VRS agent informing the VSC of the placement of a new VM, is triggered by step f in which the VM is instantiated on a hypervisor.

  C. Step b, in which the VSC queries VSD on network service and policies required for a new VM, is triggered either by API calls from the CMS or by manual configuration.

  D. Step e, in which the forwarding tables are deployed, consists of the VSC sending them not only to the VRS agent hosting the new VM, but to all applicable VRS agents.

  Correct Answer: D

• Question 12:

  What statement about stateful ACL entries is FALSE?

  A. They can track both TCP and UDP flows.

  B. They can be created in either ingress or egress directions.

  C. A packet in the direction of the stateful ACL rules will automatically create a “related” rule in the reverse direction.

  D. The automatically created rules will not go away until the ACL is manually deactivated and reactivated.

  Correct Answer: D
