Correct answer: The integrated AMD Pensando Data Processing Unit (DPU).

The HPE Aruba Networking CX 10000 integrates an AMD Pensando Data Processing Unit (DPU) directly into the switch. This DPU is responsible for delivering stateful software-defined services (like firewalling, IPsec, and telemetry) inline, eliminating the need to hairpin traffic to a centralized security appliance.

Correct answer: The tromboning or hair-pinning of East-West traffic to a centralized firewall.

In traditional architectures, East-West traffic between workloads in different subnets (or even the same subnet, for microsegmentation) must be routed to a centralized firewall, creating a 'trombone' or 'hair-pin' effect that consumes core bandwidth and adds latency. The CX 10000 applies stateful policies directly at the ToR, completely eliminating this inefficiency. flowchart LR subgraph Traditional A[Server A] --> B[ToR Switch] B --> C[Core] C --> D[Central Firewall] D --> C C --> B B --> E[Server B] end subgraph CX10000 F[Server A] --> G[CX 10000 /w DPU] G --> H[Server B] end

Correct answer: Utilizing the integrated Pensando DPU for distributed stateful firewalling combined with hypervisor-level Private VLANs or vSwitch isolation to force traffic up to the ToR.

To inspect traffic between VMs on the same host, the traffic must be forced out of the hypervisor's virtual switch up to the Top of Rack (ToR) switch. Once at the ToR, the CX 10000's Pensando DPU applies the stateful firewall policy locally. This satisfies the compliance rule without sending traffic to the core network, eliminating the congestion caused by centralized firewall topologies.

Correct answer: False

False. The Pensando DPU operates independently from the switch's main CPU and memory. AOS-CX runs on the switch CPU and handles standard L2/L3 networking, while the Pensando DPU has its own dedicated processing cores and memory for handling stateful services and telemetry.

Correct answer: A cluster of three (3) AFC nodes to establish quorum.

HPE Aruba Networking Fabric Composer (AFC) requires a cluster of three (3) virtual machine nodes to form a highly available control plane. This 3-node architecture ensures that a quorum is maintained even if one node fails, preventing split-brain scenarios and ensuring continuous orchestration capabilities.

Correct answer: Run the bootstrap script from the primary node to form the cluster.

After the PSM virtual machines are deployed, the cluster is not automatically formed. An administrator must log into the primary node and execute the bootstrap process (typically via CLI or initial web setup) to initialize the database, establish quorum among the nodes, and finalize the cluster formation.
