Aruba ACDA case studies
Aruba ACDA · Put your knowledge to work in context.
The Aruba Certified Design Associate (ACDA) is an entry-level credential for people who translate business and technical requirements into campus and branch network designs using Aruba switching, wireless, and security products. It suits pre-sales engineers, network engineers moving toward design work, and administrators who want to justify architecture decisions rather than just operate gear. The exam is multiple choice and is organized around six areas: design fundamentals and methodology, campus wired design, campus wireless design, WAN and branch connectivity, security design, and management and monitoring. Expect questions that test judgment, not just recall: given a set of constraints, which design choice fits, which technology solves the problem, and which option is over-engineered or unsafe. The Aruba ACDA case studies are 5 cases and about 1,922 words.
