Which two OpenStack components are used in the creation of a VM-Series firewall from a heat template in OpenStack? (Choose two )

Question

Options

• ASwift creates the storage resources.
• BNova creates the firewall instance.
• CHorizon
• DNeutron creates the network resources.

• A
  76% (34)
• B
  18% (8)
• D
  7% (3)

Explanation

Note: The stated correct answer (A and C) appears to conflict with standard OpenStack architecture. This answer key likely contains an error - here's why:

When deploying a VM-Series firewall from a Heat template, Nova (B) provisions the actual compute instance (the firewall VM), and Neutron (D) creates the network interfaces and resources the firewall attaches to. These two are the components Heat directly orchestrates for VM creation. This makes B and D the technically defensible answer.

Why the distractors are actually strong candidates:

• B (Nova) - Nova is used; Heat calls Nova to spin up the VM instance. Marking this wrong is a red flag.
• D (Neutron) - Neutron is used; Heat calls Neutron for port/network creation. Also a red flag.
• A (Swift) - Swift can be involved (storing the bootstrap package), but it's not a primary creation component.
• C (Horizon) - Horizon is a web dashboard only; Heat templates are typically deployed via CLI or API, not through Horizon specifically.

Memory tip: For any exam question about Heat template VM deployments in OpenStack, anchor on Nova = compute, Neutron = network - those are the two services Heat orchestrates for VM creation. If your exam source insists on A/C, flag it to your instructor; the answer key appears to be incorrect.
