1. 1A blueprint must prepare a network assignment before Self-Service provisions a service. Where should the preparation run?

   1. A.In a pre-create task for the serviceCorrect answer: A
   2. B.In a post-create task for the service
   3. C.In the install task for the service
   4. D.In a post-delete task for the service

   Explanation: The guide states: "Pre-create tasks are actions that Self-Service runs before a service is provisioned within a blueprint." This timing lets the preparation occur before provisioning.

2. 2A blueprint must use the same services and packages on different provider platforms. Which component provides different infrastructure combinations for launch?

   1. A.Application profileCorrect answer: A
   2. B.Substrate
   3. C.Package
   4. D.Service

   Explanation: The guide states: "The app profile allows you to use the same set of services and packages on the different platforms. You select an app profile while launching your blueprint." The profile selects the platform combination.

3. 3An AHV VM is powered on and its guest supports CPU and memory hot add. Which playbook action requires the VM to be powered off?

   1. A.VM Add CPU
   2. B.VM Add Memory
   3. C.VM Reduce MemoryCorrect answer: C
   4. D.VM SSH

   Explanation: The guide states: "VM Reduce Memory AHV VM must be powered off" The documented AHV prerequisite is the powered-off state.

4. 4In a Self-Service 4.3.1 pre-create workflow for dynamic cluster assignment, how is a value from a task made available as a variable?

   1. A.Use the output emitted by a Set Variable or HTTP taskCorrect answer: A
   2. B.Use the task name as the variable's cluster value
   3. C.Use the task execution status as the cluster value
   4. D.Use the HTTP request method as the cluster value

   Explanation: The workflow says: "Inside the pre-create task, create the set variable task or HTTP task that emits an output and map it to the variable." Mapping the emitted output provides the value for later use.

5. 5Which blueprint component abstracts the underlying cloud and virtual machine instance?

   1. A.Application profile
   2. B.SubstrateCorrect answer: B
   3. C.Service dependency
   4. D.Approval policy

   Explanation: The guide states: "Substrates are a combination of the underlying cloud and the virtual machine instance." The substrate represents the infrastructure layer.

6. 6A playbook must run a VM SSH action on an AHV VM. Which guest service must be enabled?

   1. A.SSHCorrect answer: A
   2. B.PowerShell remoting
   3. C.HTTP proxy
   4. D.SMTP relay

   Explanation: The guide states: "VM SSH AHV SSH must be enabled." The SSH action requires SSH.

7. 7In the documented pre-create workflow, which macro references the subnet variable in a VM network configuration field?

   1. A.@@{subnet}@@Correct answer: A
   2. B.@@{gateway}@@
   3. C.@@{dns}@@
   4. D.@@{cluster_name}@@

   Explanation: The workflow lists: "For Network: Subnet: @@{subnet}@@ Gateway: @@{gateway}@@ DNS: @@{dns}@@ For a Cluster: Cluster Name: @@{cluster_name}@@" The subnet macro supplies the subnet variable.

8. 8When are package Install and Uninstall operations normally run in an application lifecycle?

   1. A.Install at first launch; uninstall at final app deletionCorrect answer: A
   2. B.Install at app stop; uninstall at app restart
   3. C.Install at final app deletion; uninstall at first launch
   4. D.Install at app restart; uninstall at app stop

   Explanation: The guide states: "Package Install and Uninstall are operations that are run when you first launch a blueprint or when you finally delete the entire app." They correspond to create and delete profile actions.

9. 9An AHV VM is reachable, but PowerShell remoting is disabled. Which playbook action's documented prerequisite is missing?

   1. A.VM PowerShellCorrect answer: A
   2. B.VM SSH
   3. C.VM Add CPU
   4. D.VM Reduce Memory

   Explanation: The guide states: "VM Powershell AHV Powershell remoting must be enabled. ESXi Powershell remoting must be enabled." Both hypervisors require PowerShell remoting.

10. 10A pre-create workflow retrieves a subnet reference for a VM configuration. Which JSON shape must the retrieved reference use in Self-Service 4.3.1?

    1. A.{"name":"<subnet_name>","uuid":"<subnet_uuid>"}Correct answer: A
    2. B.{"name":"<subnet_name>","address":"<subnet_address>"}
    3. C.{"uuid":"<subnet_uuid>","gateway":"<gateway_address>"}
    4. D.{"subnet":"<subnet_name>","cluster":"<cluster_name>"}

    Explanation: The documented reference is “For the subnet reference to work properly, the value fetched for the subnet reference must be in the following format: {"name":"<subnet_name>","uuid":"<subnet_uuid>"}”. It contains the subnet name and UUID.
