ACA Aruba Associate Cloud & SD-WAN 2 — Questions and Answers
Question 1: What is the Aruba GreenLake platform?
- An open-source network operating system for Aruba devices
- A cloud-delivered, consumption-based IT platform for managing Aruba networking infrastructure as a service (Correct answer)
- A physical data center appliance for on-premises cloud computing
- A wireless spectrum analysis tool for RF planning
Correct answer: A cloud-delivered, consumption-based IT platform for managing Aruba networking infrastructure as a service
Aruba GreenLake is a cloud-delivered, consumption-based service model that delivers networking infrastructure and management as a service with flexible, pay-as-you-grow pricing.
Question 2: Which deployment model does Aruba Central support to allow management of both cloud-connected and on-premises infrastructure?
- Hybrid cloud management (Correct answer)
- Physical appliance management only
- Hypervisor-only deployment
- Air-gapped offline management
Correct answer: Hybrid cloud management
Aruba Central supports a hybrid cloud management model, allowing organizations to manage cloud-connected devices alongside on-premises infrastructure from the same platform.
Question 3: What is the purpose of IPSec tunnels in Aruba SD-WAN deployments?
- To increase wireless throughput at branch offices
- To create encrypted overlays over public Internet WAN links, ensuring secure branch-to-branch or branch-to-HQ traffic (Correct answer)
- To replace OSPF routing between branches
- To provide DHCP services across WAN links
Correct answer: To create encrypted overlays over public Internet WAN links, ensuring secure branch-to-branch or branch-to-HQ traffic
Aruba SD-WAN uses IPSec tunnels to encrypt traffic traversing public Internet connections, creating a secure overlay network that protects branch communications regardless of the underlying transport.
Question 4: What does Zero-Touch Provisioning (ZTP) enable in Aruba Central for branch deployments?
- Automatic wireless channel selection on all APs
- New devices automatically contact Aruba Central and receive their configuration without manual on-site setup (Correct answer)
- Automatic IPv6 address assignment to all connected devices
- Automatic license renewal for all managed devices
Correct answer: New devices automatically contact Aruba Central and receive their configuration without manual on-site setup
Zero-Touch Provisioning allows new Aruba devices to automatically register with Aruba Central and download their configuration without requiring on-site IT staff, dramatically simplifying branch deployments.
Question 5: In Aruba SD-WAN, what is a 'Business Intent Overlay' (BIO)?
- A physical VLAN segment dedicated to business-critical traffic
- A policy-driven overlay that maps application traffic to specific WAN transport paths based on business requirements (Correct answer)
- An encrypted storage area for SD-WAN configuration backups
- A reporting module that tracks WAN link costs and SLA compliance
Correct answer: A policy-driven overlay that maps application traffic to specific WAN transport paths based on business requirements
A Business Intent Overlay in Aruba SD-WAN is a policy construct that groups applications by business priority and maps them to WAN paths that meet their performance and cost requirements.
Question 6: What advantage does cloud-hosted Aruba Central provide over traditional on-premises network management systems?
- On-premises systems support more devices than cloud platforms
- Cloud hosting eliminates the need for dedicated NMS servers, reduces maintenance overhead, and provides always-current software (Correct answer)
- Cloud-based management requires lower WAN bandwidth than on-premises systems
- Aruba Central does not require any licensing unlike on-premises NMS platforms
Correct answer: Cloud hosting eliminates the need for dedicated NMS servers, reduces maintenance overhead, and provides always-current software
Cloud-hosted Aruba Central eliminates the need to provision, maintain, and update dedicated NMS server hardware, as Aruba manages the infrastructure and continuously delivers new features.
