Question #31
An Application team has provided an administrator the following high level requirements for infrastructure they require:
5 Application VMs
2 Database VMs
2 Web VMs
Which two pieces of information are needed, at a minimum, to effectively automate the scaling of the environment? (Choose two.)
- A . SLA uptime of the application
- B . Steady state resource utilization
- C . Expected resource utilization under load
- D . If the application needs to be highly available
Correct Answer: B C
B C
Explanation:
To effectively automate the scaling of the environment, the administrator needs to know the steady state resource utilization and the expected resource utilization under load of the application, database, and web VMs. These two pieces of information will help the administrator to define the scaling policies, thresholds, and actions for the blueprint service that deploys the infrastructure. The administrator can use the Self-Service feature of Nutanix Multicloud Automation to create a blueprint service that can scale up or down based on the resource utilization metrics. The administrator can also use the Runbook feature to automate the scaling actions using scripts or APIs. The other options are incorrect because:
SLA uptime of the application: This is not a piece of information that is needed to automate the scaling of the environment. The SLA uptime of the application is a performance indicator that measures the availability and reliability of the application. The administrator can use the X-Play feature of Nutanix Multicloud Automation to create event-driven playbooks that can trigger actions based on alerts or schedules to ensure the SLA uptime of the application.
If the application needs to be highly available: This is not a piece of information that is needed to automate the scaling of the environment. The high availability of the application is a design consideration that affects the architecture and configuration of the infrastructure and the application. The administrator can use the Projects feature of Nutanix Multicloud Automation to create projects that can define the availability domains, networks, and storage for the infrastructure and the application.

Question #35
A developer has been asked to ensure that when a Blueprint is executed. an IP address is reserved in the IPAM system before the execution can continue. The developer must achieve this with the least amount of work.
How should the developer satisfy this requirement?
- A . Use an application profile.
- B . Use Service dependency.
- C . Use a Pre-create task.
- D . Use an HTTP task.
Correct Answer: D
D
Explanation:
An HTTP task is a type of task that can be added to a blueprint or a runbook to perform REST API calls to external systems. An HTTP task can be used to reserve an IP address in the IPAM system before deploying a VM or an application, by sending a POST request with the required parameters and headers. The HTTP task can also capture the response from the IPAM system and store it as a variable for later use. This is the simplest and most efficient way to integrate with an IPAM system, as it does not require any additional configuration or scripting.

Question #36
An administrator receives the following error while running a script through Calm on VM:
Which two conditions could cause this issue? (Choose two.)
- A . The VM port is not allowed by the firewall.
- B . The credentials have insufficient permissions.
- C . The VM is still in the boot process.
- D . There is an error in the script.
Correct Answer: A, B
A, B
Explanation:
The error “Connection refused” can occur due to several reasons but in the context of running a script through Calm on VM, it is most likely caused by firewall restrictions or insufficient permissions. Option A suggests that the VM port is not allowed by the firewall, meaning that the firewall settings are preventing the connection. This could be because specific ports needed for the script to run are being blocked. Option B indicates that the credentials have insufficient permissions, meaning that the user or system trying to execute the script does not have the necessary permissions to establish a connection. Option C is unlikely because the VM should be ready before the script is executed. Option D is possible but not specific enough to explain the connection issue.
