What is the maximum number of Cisco ASA 5585-X appliances that are supported in a cluster?

The correct answer is A. 16. Cisco ASA 5585-X clustering supports a maximum of 16 appliances (Option A), making it Cisco's most scalable ASA platform and suitable for large enterprise and service provider deployments requiring high throughput and redundancy.

Explanation

Cisco ASA 5585-X clustering supports a maximum of 16 appliances (Option A), making it Cisco's most scalable ASA platform and suitable for large enterprise and service provider deployments requiring high throughput and redundancy.

Why the distractors are wrong:

B (8) is the maximum cluster size for the smaller ASA 5500-X series (e.g., 5506-X through 5555-X) - a common trap for candidates who confuse the two platform families.
C (2) describes a traditional active/standby failover pair, not a cluster - conflating failover with clustering is a frequent mistake.
D (20) simply exceeds the documented maximum for any ASA platform and is a distractor with no real-world basis.

Memory tip: Associate the "85" in 5585-X with being the top-tier platform, earning it the top cluster count - 16 nodes. If a question mentions the 5585-X and clustering, think "flagship platform = maximum scale = 16."
