HP Updated HPE7-A03 Exam Questions and Answers by marlow

In a 3-tier network design consisting of core, aggregation, and access layers, the implementation of Virtual Switching Extension (VSX) at the core is considered a best practice when the aggregation layer functions primarily at Layer 3 with routing protocols like OSPF facilitating traffic forwarding between the core and aggregation layers. This design choice, as verified by Aruba Campus Access documents, leverages the high availability and redundancy features of VSX technology while maintaining efficient and scalable routing at the aggregation layer. Implementing VSX at the core in such a scenario ensures seamless failover and redundancy, minimizing the risk of downtime and ensuring consistent performance across the network. The core layer, equipped with VSX, provides a robust and resilient backbone for the network, facilitating efficient traffic management and routing decisions, which is critical for large-scale enterprise networks.

• CISO: responsible for establishing security policy and selecting security controls for the infrastructure.
• Network Design/Architecture: responsible for authoring the low-level design, and creating the configuration to meet the technical requirements.
• Network Operations: responsible for supporting, troubleshooting, and monitoring the wired/wireless infrastructure.
• Security Operations: responsible for investigating IDS/IPS incidents and managing firewalls.

In the context of responding to an RFP (Request for Proposal), it is common to make certain assumptions about the project environment when specific details are not provided. Answer A is valid because assuming the customer has technically capable staff is essential for the successful implementation of the proposed equipment; if this is not the case, additional training or services may be needed. Answer D is a reasonable assumption as well, given that physical space and power are fundamental requirements for installing new hardware; however, this should be clarified to avoid potential issues during deployment. Answer E is also a valid assumption, especially in modern network environments where management and orchestration systems often reside on virtual machines; assuming there are adequate resources for these systems is critical for the overall solution but should be verified with the customer. These assumptions are important to present to the customer to ensure there are no misunderstandings or gaps in the project planning phase, as highlighted in Aruba Campus Access documentation.
