While completing the install of OpenStack, you upload the Cirros image the CLI to validate the Glance install. However, it times out after a short time. You review the logs located at /var/log/glance/api.log.
Referring to the exhibit, which action will solve this problem?
- A . Set the glance.api version to version 1 and retry the upload.
- B . Get a new Cirros image; the current image is corrupted.
- C . Replace the schema image file with the correct name of the image.
- D . Update the GLANCE DBPASS in the keystone.conf file.
You have configured an SR-IOV interface on a virtual host machine in your Contrail network environment. You discover that analytics data is not being recorded for traffic to the customer’s VM that uses the SR-IOV interface.
Which two statements are true in this scenario? (Choose two.)
- A . You cannot perform analytics on the SR-IOV interface traffic.
- B . The SR-IOV interface must be re-added to the analytics engine.
- C . The data of packets going to the VM does not go through the vRouter on the host.
- D . You must use the tap interface on the Contrail vRouter to collect SR-IOV analytics data.
hat are two Keystone endpoint types? (Choose two.)
- A . root
- B . admin
- C . rbac
- D . public

What is the role of an orchestration platform in a cloud networking environment?
- A . It controls and monitors the network underlay infrastructure.
- B . It controls pools of compute, storage, and networking resources.
- C . In configures and monitors tunnels between physical hosts.
- D . It configures and monitors tunnels between virtual hosts.
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?
- A . The packet sniffing service must be performed on the edge routers facing the Internet.
- B . The packet sniffing service must be enabled on the vRouter directly attached to the customer’s VM.
- C . The packet sniffing service can be implemented on any physical host in the cloud environment.
- D . The packet sniffing service can be implemented on any switch within the underlay fabric.
Which two OpenStack projects contain networking components? (Choose two.)
- A . Keystone
- B . Magnum
- C . Nova
- D . Neutron
Which statement is true regarding Virtual Network Functions (VNF)?
- A . A VNF is implemented with virtual platforms.
- B . A VNF requires an SDN controller for implementation.
- C . A VNF is implemented with physical hardware platforms.
- D . A VNF requires an SDN orchestrator for implementation.
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?
- A . 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.
- B . 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.
- C . 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.
- D . 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
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?
- A . IaaS
- B . PaaS
- C . DBaaS
- D . SaaS
