Your customer has four (4) Aruba 7200 Series Gateways and two (2) 7000 Series Gateways. The customer wants to form a cluster with these Gateways. What design consideration would prevent you from…

Question

Options

• AMultiple versions between Gateways in the same cluster profile are not allowed AOS 10.x.
• BA heterogeneous cluster is not supported in AOS 10.x.
• CThe AP load should be lowest value of worst-case scenario load.
• DA combination of 7200 series and 7000 series gateways supports up to 4 nodes

• A
  7% (4)
• B
  14% (8)
• C
  4% (2)
• D
  75% (43)

Explanation

Option D is correct because in AOS 10.x, a mixed (heterogeneous) cluster combining 7200 Series and 7000 Series Gateways is capped at 4 nodes. Since the customer has 6 Gateways total (4 + 2), they cannot include all of them in a single cluster - the 4-node ceiling is the blocking design constraint.

Why the distractors are wrong:

• A is wrong because the question gives no indication that different AOS versions are running across the Gateways; version mismatch is a real restriction, but it's not the issue presented here.
• B is wrong because it's the opposite of the truth - heterogeneous clusters are supported in AOS 10.x; they're just limited in size, which is exactly what D describes.
• C is wrong because AP load worst-case sizing is a capacity planning consideration, not a constraint on how many Gateways can join a cluster.

Memory tip: Think "mixed series = max 4." If you ever see different Aruba Gateway series combined, the ceiling is 4 nodes - so count your hardware before designing the cluster.
