AutoSupport can be manually triggered using the ONTAP CLI command or via System Manager. Ping tests and Unified Manager do not trigger AutoSupport generation.

NVMe access in ONTAP is controlled through NVMe subsystems , not igroups. A namespace must be explicitly mapped to a subsystem to allow host access. If the namespace is not added to the subsystem, the host cannot discover or connect to it.

Additionally, NVMe access control relies on NQNs (NVMe Qualified Names) . If the subsystem is configured with an incorrect host NQN, authentication fails and the host is denied access.

Igroups are used for iSCSI and FC, not NVMe, making options B and C incorrect.

Therefore, the correct answers are A and D .

Flow control configuration is an important validation step in ONTAP SAN and NAS environments, especially in switchless cluster designs. NetApp documentation clearly differentiates flow control requirements between data networks and cluster networks.

For data network ports, full flow control must be enabled when hosts are configured with full flow control. This ensures proper congestion management and prevents packet loss during high-throughput NAS operations such as NFSv4.1 and SMB traffic. Matching flow control settings between hosts and storage data ports is a best practice explicitly stated in NetApp installation guidance.

In contrast, cluster network ports must have flow control disabled. The cluster network is highly sensitive to latency and congestion, and enabling flow control on cluster interconnect ports can introduce delays that negatively affect cluster quorum, node communication, and overall stability. NetApp explicitly requires flow control to be disabled on cluster network interfaces.

Enabling flow control on cluster ports or disabling it on data ports would violate NetApp-supported configurations and can lead to performance degradation or cluster communication issues.

Therefore, the two correct settings to verify are:

Data network ports have full flow control enabled

Cluster network ports have full flow control disabled

This makes C and D the correct answers.

Cluster peering enables data replication and disaster recovery features such as SnapMirror and SnapVault. LIF configuration for cluster peering follows specific ONTAP SAN concepts.

Each cluster participating in a peer relationship must have at least one intercluster LIF per node . This ensures redundancy and allows ONTAP to balance replication traffic across nodes.

Additionally, intercluster LIFs must use the default intercluster service policy , which defines the permitted traffic types and security rules required for peering operations.

An MTU of 9000 is recommended but not mandatory. Dedicated broadcast domains or IPspaces are optional and depend on network design.

Therefore, the correct answers are B and D .

Within the ONTAP SAN implementation testing and troubleshooting domain, NetApp places strong emphasis on post-installation validation tools . One of the primary tools used immediately after installation is Active IQ Config Advisor .

Active IQ Config Advisor is designed specifically to validate hardware configuration, cabling, HA connectivity, and SAS topology . During post-installation checks, Config Advisor scans the system for configuration errors, miswired cables, unsupported connections, and SAS HA path issues. These checks are a mandatory part of NetApp installation best practices.

SAS HA issues, such as incorrect shelf cabling, missing redundant paths, or improper HA connections, are precisely the types of errors Config Advisor is designed to detect. It performs rule-based validation against NetApp-supported configurations and flags deviations before they result in operational problems.

By contrast, ONTAP System Manager displays events and alerts after the system is already operational, but it is not a post-installation validation tool. Cloud Manager is used for cloud-based storage management and is not applicable to on-premises AFF hardware validation. Active IQ Unified Manager focuses on long-term monitoring, performance analytics, and capacity planning rather than installation-time hardware verification.

Because the errors were related to SAS HA issues that could have been detected immediately after installation, the correct tool is Active IQ Config Advisor .

Therefore, the correct answer is C .
