Demo Questions

Question 1
Refer to the exhibit. 
  
You have a Contrail providing cloud services to Customer A. Customer A wants to add a packet capture service to their network to analyze traffic flowing to and from the Internet. 
Referring to the exhibit, which statement is true?  
  1. The packet sniffing service must be performed on the edge routers facing the Internet.
  2. The packet sniffing service must be enabled on the vRouter directly attached to the customer’s VM.
  3. The packet sniffing service can be implemented on any physical host in the cloud environment.
  4. The packet sniffing service can be implemented on any switch within the underlay fabric.
Correct answer: B
Question 2
Which two OpenStack projects contain networking components? (Choose two.) 
  1. Keystone
  2. Magnum
  3. Nova
  4. Neutron
Correct answer: BD
Question 3
Which statement is true regarding Virtual Network Functions (VNF)?
  1. A VNF is implemented with virtual platforms.
  2. A VNF requires an SDN controller for implementation. 
  3. A VNF is implemented with physical hardware platforms.
  4. A VNF requires an SDN orchestrator for implementation.
Correct answer: A
Question 4
You are required to implement a Contrail service that will automatically increase network resources for that service when under high traffic loads, and reduce network resources for that service under low traffic loads. 
Which configuration steps will accomplish this task?
  1. Configure Heat to monitor the CPU threshold of services VMs, and configure a Heat auto-scaling policy to adjust the VM resources allocated to the service.
  2. Configure Ceilometer to monitor the CPU threshold of services VMs, and configure a Ceilometer auto-scaling policy to adjust the VM resources allocated to the service.
  3. Configure Heat to monitor the CPU threshold of services VMs, and configure a Ceilometer auto-scaling policy to adjust the VM resources based on alarms generated by Heat.
  4. Configure Ceilometer to monitor the CPU threshold of services VMs, and configure a Heat auto-scaling policy to adjust VM resources based on the alarms generated by Ceilometer
Correct answer: D
Question 5
You want to deploy an application to the cloud so that the application instances can be dynamically mirrored. You want to manage only the application, leaving all other management to the cloud provider. 
Which type of cloud service should you choose in this situation?
  1. IaaS
  2. PaaS 
  3. DBaaS
  4. SaaS
Correct answer: B
Question 6
You are implementing an OpenStack environment and need to install the Glance service on the control node. 
Which two actions must take place to successfully complete this action? (Choose two.)
  1. Create the API endpoints in Keystone.
  2. Create a new availability zone for Glance.
  3. Create the Glance service credentials.
  4. Create local storage capacity for Glance images.
Correct answer: AC

Question 7
You are using OpenStack as the orchestrator for your data center. You need to instantiate several instances of a webserver. There is a requirement that each webserver VM must have six VCPUs and 32 GB of RAM. 
Where in OpenStack’s Web user interface would you set up these resources?
  1. Project>Compute>Instances
  2. Orchestration>Stacks
  3. Project>Compute>Images
  4. Admin>System>Flavors 
Correct answer: D

Question 8
You are asked to create a Contrail service instance between two virtual networks. The left virtual network is a private virtual network. The routes from the left virtual network VRF should not be leaked into the right virtual network VRF. 
Which Contrail service instance type would you choose in this scenario?
  1. In-network private
  2. In-network NAT
  3. In-Network
  4. Transparent
Correct answer: B
Question 9
Refer to the exhibit. 
  
Virtual machine VM-1 is spawned on a compute node Compute-1. VM-1 is not able to ping PC-1, which is located outside of the SDN cloud. You want to run packet captures to trace the packet initiated by VM-1 towards PC-1. 
Referring to the exhibit, which three interfaces would you use to accomplish this task? (Choose three.)
  1. The SDN-GW interface facing the SDN cloud
  2. The Control-1 data interface
  3. The Compute-1 data interface
  4. The VM-1 tap interface
  5. The Compute-2 data interface
Correct answer: ACD
Explanation:
Question 10
What is needed to move compute resources between cloud environment?
  1. Orchestration software
  2. Data compression software
  3. Firewall software
  4. Load-balancing software
Correct answer: A
