Which three statements are true about Oracle Flex ASM? (Choose three.)
The correct answer is C. The SPFILE and password file for ASM are stored by default an ASM disk group. E. A designated network is used for communication between ASM instances and their clients. F. ASM clients can fail over to other ASM instances. See the full explanation below for the reasoning.

Brenda K.Mar 3, 2026C, E, and F are your three. Flex ASM stores the SPFILE and password file in an ASM disk group by default, uses a dedicated network for ASM-to-client communication to isolate that traffic, and gives clients automatic failover to another ASM instance if their current one goes down. Flag B on sight because Flex ASM supports up to three ASM instances on a standard cluster but that number is not a hard ceiling in all configurations, and A is flat wrong because Flex ASM does not require a Flex cluster.
Mei-Ling H.Mar 5, 2026Good picks on C, E, F, but watch the exact wording on B when you see it on the exam, because some question versions say "exactly three ASM instances" and some say "up to three," and that difference in qualifier changes whether it is flat wrong or just misleading.
Imani T.Feb 28, 2026So C, E and F are the right picks here, which makes sense once you understand that Flex ASM is really built around two things, centralized metadata storage and network-based client-to-instance communication. My question is, when you say the SPFILE and password file are stored in an ASM disk group by default, are you clear on which specific disk group that is and what happens to ASM clients during an instance failure, because those two points tie C, E, and F together pretty tightly?
Mei-Ling H.Feb 2, 2026Yes, C, E, and F are correct. The key detail that ties E and F together is that the dedicated ASM network is exactly what makes client failover in F possible, because if one ASM instance goes down the client can reconnect to another using that same private interconnect without going through the public network.
Lena V.Jan 26, 2026A has to be in the answer set, and I will die on this hill. Flex ASM is literally defined in the context of Flex Clusters, the whole architecture assumes that separation of ASM from compute nodes, so saying it does not require a Flex cluster makes zero sense to me because that is the entire point of the feature. C, E, and F also look solid to me but A is the one I am most sure about going into test day.
Mei-Ling H.Jan 27, 2026Lena, the trick is that A flips the dependency backwards, because Flex ASM does not require a Flex Cluster, it can actually run on a standard cluster as well, so that statement is false and gets dropped from the answer set. C, E, and F are the ones Oracle tests on here.
Prof. SaraFeb 12, 2026D has to be in the answer set because the whole point of Flex ASM is that leaf nodes do not need to run a local ASM instance, yet the architecture absolutely permits an ASM instance on a leaf node when the configuration calls for it, which is precisely what distinguishes Flex from standard ASM. If leaf nodes were categorically excluded from hosting ASM instances, Oracle would have no reason to define the hub-and-leaf distinction at all.
Imani T.Feb 14, 2026Sara, I appreciate the reasoning but it actually flips the definition, because a leaf node is specifically characterized by NOT running a local ASM instance and instead connecting to a hub node's ASM remotely, which is exactly why C, E, and F are correct. The hub-leaf distinction exists to describe that separation of roles, not to imply leaves can optionally host ASM when configured to do so.
