You are part of a cross-functional team preparing a detailed design proposal for a customer deploying EVPN-VXLAN in a modern campus core and data center fabric. The customer is transitioning from a traditional VLAN-based Layer 2 design to a VXLAN-based overlay architecture to support segmentation scalability, and automation.
As the solution is reviewed, you're asked to contribute by identifying and explaining core technical behaviors and configuration considerations that are critical to the success of EVPN-VXLAN in this environment.
Which statement accurately describe key characteristics of EVPN-VXLAN in modern campus or data center networks? (Choose two.)
A. MP-BGP is utilized as the control plane that establishes GRE over UDP between VTEPs. known as VXLAN.
B. ARP suppression is supported in EVPN-VXLAN fabrics through host route information carried in EVPN Type-2 NLRI.
C. Virtual Network Based Tunneling (VBNT) is a term used to describe static segmentation based on EVPN-VXLAN.
D. VTEPs apply unique Route Distinguishers prefixes to NLRI records, enabling selective advertising.
正解：B、D
解説：
EVPN-VXLAN uses EVPN Type-2 routes to distribute MAC and IP (host) information, enabling ARP suppression by allowing VTEPs to respond locally without flooding.
Route Distinguishers are applied to EVPN NLRI to ensure uniqueness of routes across different VTEPs and allow proper control plane operation and route advertisement.

A large multinational financial institution has contracted you to design a new full-stack wired and wireless network for their new 6-story regional office building. The bottom two floors of this facility will be retail space for a large banking branch. The upper floors will be carpeted office space for corporate users, each floor being approximately 100,000 sq ft (9290 sq m). Data centers are all offsite and will be out of scope for this project. The customer is underserved by its existing L2- based network infrastructure and would like to take advantage of modem best practices in the new design. The network should be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will include public guest Wi-Fi access. Retail associates will have corporate tablets for customer service, and there will be a mix of wired and wireless devices throughout the retail floors. The corporate users will primarily use wireless for connectivity, but several wired clients, printers, and hard VoIP phones will be in use.
The customer is also planning on renovating the corporate office space in order to take advantage of 'smart office' technology. These improvements will drive blue-dot wayfinding, presence analytics, and other location-based services.
The client would like to ensure full wireless coverage in its 40 m x 40 m (130 ft x 130 ft) auditorium during company functions while maintaining the fewest APs for aesthetic purposes.
Wi-Fi6 APs are a minimum requirement.
Which AP series would you use in the auditorium's 1,000 seats with a maximum take rate of
80%?
A. AP577
B. AP635
C. AP515
D. AP555
正解：B
解説：
The Aruba AP-635 is a Wi-Fi 6 (802.11ax) access point, designed for high-density environments such as auditoriums. It is capable of providing high throughput and efficient airtime fairness to a large number of clients, which makes it suitable for an auditorium setting with 1,000 seats and a high take rate. The AP-635's advanced capabilities, including OFDMA and MU-MIMO, allow it to handle multiple simultaneous connections efficiently, ensuring robust wireless coverage and performance during company functions, all while keeping the number of APs to a minimum to satisfy aesthetic concerns.

What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?
A. Access aggregation points are not scaling to meet traffic demands.
B. Cross-campus traffic has grown beyond We capacity of a single collapsed core
C. The network has grown beyond a few building aggregation points
D. The campus has small buildings with only a few wiring closets.
正解：D
解説：
A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for smaller campuses or networks with limited numbers of wiring closets. This simplified architecture eliminates the need for a dedicated aggregation layer, which is more common in larger, more complex network environments (the 3-tier architecture). In a small campus setting with only a few wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity and potentially lowering costs. This architecture allows for direct connectivity between the access layer, where end devices connect to the network, and the core layer, which routes traffic to and from the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size and the simplicity of its requirements, making it an efficient and effective choice.
質問 # 52
What is the main purpose of an HPE FlexFabric switch in a campus network?
A. To connect end-user devices to the network
B. To optimize the backbone of the network
C. To provide power over Ethernet
D. To enable wireless networking
正解：B
解説：
HPE FlexFabric switches are primarily used in the core or distribution layers of a campus network. These switches are designed to connect multiple network devices across different segments of the network, ensuring high-performance and optimized backbone connections.
質問 # 53
You are delivering a replacement collapsed core network proposal to the customer where the core switches will have the switched virtual interlaces (SVl) configured. The customer is not sure that a USX pair of switches will Be able to act as I tie spanning tree root in their environment.
Which options are true about spanning tiee and VSX that will help assure the customer that a VSX pair of switches are appropriate for a collapsed core? (Select two.)
A. The ISL between VSX switches is never part of STP domain and doesn't send or receive BPDUs on this link and this ensures the "operational primary" and "operational secondary" switches are deterministic to other dual-attached switches.
B. When LAG interfaces are configured on a VSX pair of switches, both switches are "operational primary" and ensure active-active LAG operation equally.
C. Aruba VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST).
D. Both VSX switches are configured with the system MAC and then create unique STP bridge-IDs to identify "operational primary" and "operational secondary" for proper STP functioning
E. The primary vsx switch ts the spanning tree root and the default behavior is the links on the secondary vsx switch are blocked with sub-millisecond failover assured by vsx active-gateway.
正解：A、C
解説：
According to Aruba Campus Access documents and learning resources, Aruba VSX (Virtual Switching Extension) technology is designed to provide advanced high availability and redundancy features for campus networks. Specifically, answer D is correct because Aruba VSX supports both Multiple Spanning Tree Protocol (MSTP) and Rapid Per VLAN Spanning Tree (RPVST), ensuring efficient tree structures for VLANs and rapid convergence in case of topology changes. Answer E is also true as the Inter-Switch Link (ISL) used for the VSX pair is not part of the Spanning Tree Protocol (STP) domain, meaning it does not send or receive Bridge Protocol Data Units (BPDUs). This design prevents the ISL from influencing STP calculations, ensuring that the operational roles of the primary and secondary switches in the VSX pair are clear and predictable to the rest of the network. This separation helps maintain deterministic behavior and failover capabilities in the network, aligning with the goals of a collapsed core network design.
