질문 # 32
You are designing a pair of CX switches to function as ToR switches. The switches use VSX in a data-center Layer 2 topology and connect to the core through VSX LAGs. To satisfy expansion requirements, you must keep as many ports available as possible.
Which option should you recommend for VSX keepalives?
정답：C
설명：
ArubaOS-CX Virtual Switching Extension (VSX) relies on two communication channels between peer switches: the Inter-Switch Link (ISL) and the peer keepalive link. The ISL is a high-speed Layer 2 transport link that carries state synchronization (VSX-sync), control protocols, and data plane traffic when necessary.
The peer keepalive link operates strictly as a heartbeat mechanism over a Layer 3 path, allowing each switch to detect peer liveness and prevent split-brain scenarios if the ISL experiences a catastrophic physical failure.
A fundamental rule of VSX architecture dictates that the peer keepalive path must be completely independent and isolated from the ISL data plane. While architects can deploy a dedicated front-panel data port configured with a routed IP address in a separate VRF, doing so consumes valuable front-panel interfaces that could otherwise provide server downlink connectivity.
To optimize port density and maximize available access interfaces for future expansion, HPE best practices recommend utilizing the dedicated Out-of-Band Management (OOBM) Ethernet port (mgmt interface) for VSX keepalives. Because OOBM interfaces operate inside the isolated mgmt VRF and traverse an external management network switch, they provide the necessary physical and logical separation from the production data plane without consuming high-speed front-panel ports.

질문 # 33
A customer is upgrading its data-center structured cabling to SMF. At the same time, the customer wants to upgrade the spine switches in its spine-and-leaf topology. A key objective of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for some time, many leaf switches will continue to support
100GbE uplinks.
What is a valid recommendation for the spine switches?
정답：B
설명：
Modern data center physical layer design requires balancing long-term bandwidth migration with backward compatibility for existing access tiers. In this scenario, the customer has upgraded the cabling plant to Single- Mode Fiber (OS2) and requires spine switches capable of native 400GbE forwarding, while currently accommodating legacy 100GbE leaf uplinks.
The HPE Aruba CX 9300-32D switch is the premier fixed 1U data center spine platform, delivering 32 ports of high-density 400GbE QSFP-DD (Double Density). To interface with existing 100GbE leaf switches over single-mode fiber, the architect must specify 400G 4x100G DR (Datacenter Reach) QSFP-DD transceivers.
The 400G DR4/eDR4 optical architecture utilizes four parallel single-mode fiber pairs (transmitting over an MPO-12/APC single-mode trunk) where each optical lane operates at 100Gbps using PAM4 modulation. By utilizing an optical breakout cable, each 400G QSFP-DD port splits cleanly into four discrete 100G DR (or
100G FR/LR via interoperable optical gear) links connecting to standard 100GbE QSFP28 leaf uplinks. MPO-
16 SR8 transceivers are engineered strictly for Multi-Mode Fiber (MMF) short-reach optics and are physically incompatible with SMF plants.

질문 # 34
A long-time customer has just acquired a company and plans to bring the new data-center sites up to its standards. The customer has requested a bill of materials based only on the locations and port counts at the data-center sites.
Which valid assumptions should be documented in the proposal? Choose two.
정답：A,D
설명：
Generating an equipment proposal without detailed site surveys requires the architect to document baseline physical site assumptions to protect against unbudgeted installation failures. In data center environments, two critical physical parameters are rack infrastructure compliance and thermal airflow compatibility.
First, the architect must assume that the server racks at the acquired company ' s data centers possess sufficient available vertical rack units (RU), appropriate depth, and load-bearing capacity to safely house the proposed switches, power feeds, and cable management arms, and that they will be reused.
Second, data center cooling efficiency depends on aligning equipment intake and exhaust with the facility ' s hot-aisle/cold-aisle containment layout. If the purchasing customer requires back-to-front (power-to-port) airflow to match existing operational conventions, the architect must assume the target facilities have cooling plants and ducting capable of sustaining that specific thermodynamic profile. Stating these physical assumptions ensures that if rack replacements or cooling reconfigurations are discovered during implementation, the necessary additions fall outside the scope of the preliminary proposal. Staff employment terms and funding source classifications are corporate governance issues, not engineering assumptions.

질문 # 35
Can EVPN/VXLAN fabrics be configured to provide protection against Layer 2 loops?
정답：B
설명：
While Ethernet VPN (EVPN) control-plane logic and the underlying BGP routed fabric prevent Layer 3 routing loops via standard Split Horizon and BGP path attribute mechanisms, Layer 2 overlay fabrics remain vulnerable to Layer 2 bridging loops. Such loops typically arise from accidental physical cross-connects, external unmanaged switches, misconfigured hypervisor virtual switches, or redundant Layer 2 interconnections between tenant segments.
Standard Spanning Tree Protocol (STP) instances are terminated locally at the Virtual Tunnel Endpoint (VTEP) access ports and are not encapsulated or transmitted across the VXLAN overlay tunnels by default.
To address this risk, ArubaOS-CX provides native support for Loop Protection over VXLAN interfaces.
When Loop Protection is enabled across the VXLAN configuration in AOS-CX, the VTEP switch periodically transmits proprietary loop-protect probe packets into the VXLAN Network Identifier (VNI) overlay across its VXLAN tunnel interfaces. If a VTEP detects its own loop-protection probe returning on an overlay interface or a corresponding local port associated with that same VNI, it identifies an active forwarding loop and takes defensive action-typically disabling the offending local interface or alerting network operators. This prevents broadcast storms from crippling overlay fabric resources.

질문 # 36
Waratah Hospital, located in Australia, plans to move many data center services to a new facility. (The remaining legacy data center is not included in this project.) Waratah Hospital engaged an external consultant to help with the new data center network design.
Based on the data center network-infrastructure requirements, the external consultant has produced a high- level design. The following summarizes the design document's contents.
Requirements and information:
Six racks in the data center room (a single row).
Redundant Top of Rack leaf switches with back-to-front cooling in every rack, delivering 10/25 Gbps connectivity to servers, storage, and other devices.
Four 100 GbE uplinks per leaf switch.
The customer requested that all switch ports face the back of the racks (hot aisle).
OOB management for servers, storage, and network must be delivered through an external switch with back- to-front cooling. This switch must be included in the solution. One OOB switch provides connectivity for two racks.
Core equipment for the OOBM network is being reused.
Middle-of-row spine switches.
The data center must connect to the hospital building with links providing 400 Gbps.
Internet access is provided through an existing firewall cluster with two firewalls, with each firewall in one data room. The second firewall operates in standby mode, and VRRP is used on the firewalls for failover. The data center network must connect to these firewalls with links totaling 100 Gbps.
The external link is a dark-fiber direct link based on single-mode fiber (OS2). The distance to the main hospital is 1.5 KM. The links will terminate on two core switches in the hospital.
The customer also requires:
99.999% uptime for this life-critical environment.
Planned and unplanned downtime must be minimized.
Software upgrades are permitted only once per year with close to zero downtime.
All life-critical resources are accessed locally, and all resources are within the hospital campus.
Waratah Hospital requires a highly secure data-center environment. Encrypted wire-speed connectivity between the data room and the hospital is mandatory because the link between the buildings crosses a public road.
Waratah Hospital has a mix of virtualized (vSphere) servers, Nutanix storage, bare-metal servers, backup servers, and other devices.
In the past, the hospital experienced a security breach that caused data loss, network downtime, and identity theft.
Refer to the scenario. You have learned that the customer must extend two VRFs between the new data center network and the firewall. To meet the scenario requirements and general best practices, what should you recommend for connecting border leaf switches to the hospital core?
정답：B
설명：
Connecting an external active/standby firewall cluster running VRRP to an ArubaOS-CX border leaf tier requires an architecture that prevents split-brain forwarding while delivering multi-VRF segmentation.
Because the firewall cluster operates in an active/standby model with VRRP, terminating links into a single unified aggregation group across the two discrete physical firewall chassis is not possible with standard LACP. Instead, the border leaf switches (operating as a VSX pair) must present a separate multi-chassis link aggregation group (VSX LAG) to each individual firewall. Deploying one VSX LAG to Firewall 1 and a second VSX LAG to Firewall 2 ensures that both the active and standby appliances are dual-homed across both border switches.
Utilizing 25 GbE links across the border leaf switches provides the required aggregate bandwidth. To support the two distinct VRFs without consuming additional physical interfaces, the links operate as 802.1Q trunks carrying two discrete transit VLANs, mapped to two Switched Virtual Interfaces (SVIs) on each VSX LAG.
This design allows VRRP hello packets and failover transitions to operate natively within each VLAN/VRF domain, maintaining high availability and routing isolation.
