Which statement is accurate about Virtual Network Functions (VNFs)?
AA VNF is implemented with virtual platforms.
BA VNF requires an SDN controller for implementation.
CA VNF is implemented with physical hardware platforms.
DA VNF requires an SDN orchestrator for implementation.
You need to implement a Contrail service that automatically increases that service’s network resources during high traffic loads and reduces its network resources during low traffic loads.
Which configuration steps accomplish this task?
AConfigure 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.
BConfigure 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.
CConfigure 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.
DConfigure Ceilometer to monitor the CPU threshold of services VMs, and configure a Heat auto-scaling policy to adjust VM resources based on the alarms
You want to deploy an application in the cloud so that its instances can be dynamically mirrored. You want to manage only the application and leave all other management to the cloud provider.
Which type of cloud service should you select for this situation?
AIaaS
BPaaS
CDBaaS
DSaaS
A load-balancing service has been deployed for a customer's data-cache system in a Contrail cloud-networking environment. Because of network-capacity requirements, the caching servers must be moved to a different equipment rack within the data center.
Which two statements are true in this situation?
Choose two
AA new load-balancing service will be provisioned by the orchestrator prior to moving the caching servers.
BThe orchestration platform can remap the traffic through the existing load-balancing service once the caching servers are moved.
CThe load-balancing service must be decommissioned and re-provisioned once the caching servers are moved.
DThe load-balancing service can be migrated to the vRouters where the caching servers are located.
You are deploying an OpenStack environment and must install the Glance service on the control node.
Which two actions must be completed to successfully perform this task?
Choose two
ACreate the API endpoints in Keystone.
BCreate a new availability zone for Glance.
CCreate the Glance service credentials.
DCreate local storage capacity for Glance images.
You are using OpenStack as the orchestrator for your data center. You need to instantiate several webserver instances. Each webserver VM is required to have six VCPUs and 32 GB of RAM.
Where in the OpenStack web user interface would you configure these resources?
AProject>Compute>Instances
BOrchestration>Stacks
CProject>Compute>Images
DAdmin>System>Flavors
You need to create a Contrail service instance between two virtual networks. The left virtual network is private. Routes from the left virtual network VRF must not be leaked into the right virtual network VRF.
Which Contrail service-instance type should you select for this scenario?
AIn-network private
BIn-network NAT
CIn-Network
DTransparent
What is required to move compute resources between cloud environments?
AOrchestration software
BData compression software
CFirewall software
DLoad-balancing software
Which three elements must be configured to create a Contrail service chain?
Choose three
AService Policy
BService template
CService object
DService network
EService instance
Refer to the exhibit.
You have a Contrail deployment that provides cloud services to Customer A. Customer A wants to add a packet-capture service to its network to analyze traffic flowing to and from the Internet.
With reference to the exhibit, which statement is true?
AThe packet sniffing service must be performed on the edge routers facing the Internet.
BThe packet sniffing service must be enabled on the vRouter directly attached to the customer’s VM.
CThe packet sniffing service can be implemented on any physical host in the cloud environment.
DThe packet sniffing service can be implemented on any switch within the underlay fabric.
Which command shows the routes in a vRouter VRF?
Art
Bshow route
Cshow route table vrf-name
Droute print
Which three load-balancing algorithms does Contrail’s LBaaS feature support?
Choose three
ADestination port
BSource IP
CWeighted round-robin
DLeast connections
EECMP
Which mechanism is used to create unique tenants in OpenStack?
AGroup
BProfile
CGuest
DProject
Two virtual machines located in separate virtual networks cannot communicate with one another.
Which two troubleshooting steps would help identify the problem?
Choose two
AEnsure that the SDN gateway has the VRF or VRFs created for the two virtual networks.
BEnsure that there is a default route in each virtual network’s VRF.
CEnsure that there is a Contrail policy between the two virtual networks.
DRun the tcpdump command on the virtual machine’s tap interface.
Refer to the exhibit.
Virtual machine VM-1 is launched on compute node Compute-1. VM-1 cannot ping PC-1, which is outside the SDN cloud. You want to run packet captures to trace the packet sent by VM-1 toward PC-1.
Referring to the exhibit, which three interfaces would you use to accomplish this task?
Choose three
AThe SDN-GW interface facing the SDN cloud
BThe Control-1 data interface
CThe Compute-1 data interface
DThe VM-1 tap interface
EThe Compute-2 data interface
Refer to the exhibit.
Based on the exhibit, what does the IP address 10.1.1.2 represent in Contrail's api_server.conf file?
AThe physical server IP address
BThe OpenStack controller IP address
CThe Server Web UI IP address
DThe Contrail IP address
A developer is logged in to OpenStack and is attempting to bring up a recently assigned project, but is rejected at the identify source.
Which log file should be reviewed to identify this issue?
A/var/log/keystone.log
Bvar/log/apache2/horizon.log
Cvar/log/swift.log
Dvar/log/neutron.log
Which two statements are correct about the Network Function Virtualization (NFS) framework?
Choose two
