HPE Network Data Center Professional Architect Exam HPE7-A12 Question # 3 Topic 1 Discussion
HPE7-A12 Exam Topic 1 Question 3 Discussion:
Question #: 3
Topic #: 1
You are completing a proposal for a data center network that includes 14 CX 8325 switches, 6 CX 6300M switches, and Fabric Composer licenses for these switches.
What is one assumption that could be included in the assumptions documentation?
A.
The customer has sufficient OPEX budget to pay for the Fabric Composer licenses
B.
The customer has ESXi or KVM hosts that have sufficient resources to run Fabric Composer and can connect to the OOBM network.
C.
The customer has an Internet connection over which switches ' mgmt ports can receive access to the cloud-based management solution.
D.
The customer has attended or enrolled for training on using Fabric Composer.
When documenting technical assumptions within a formal architectural design deliverable, the architect must outline external technical dependencies outside the scope of the immediate hardware deliverable that are necessary for solution deployment.
Aruba Fabric Composer (AFC) is deployed as a software appliance packaged as an OVA or virtual machine image. AFC runs on hypervisor platforms, officially supported on VMware ESXi or Red Hat Enterprise Linux KVM environments. Furthermore, for AFC to orchestrate and automate switch provisioning, its virtual interfaces must have direct Layer 3 network reachability to the physical switch out-of-band management (OOBM) VRFs.
Therefore, stating that the customer provides adequate compute, storage, and networking resources on existing hypervisors—along with verified connectivity to the physical management network—is a foundational technical assumption. Operational expenditure budgeting, operator training schedules, and public cloud connectivity do not constitute operational technical prerequisites for deploying on-premises AFC appliance clusters.
