AutoSupport verification requires checking history and generating a test message. The history command confirms delivery, and invoke sends a test AutoSupport. Therefore,A and Dare correct.

Within the ONTAP SAN solution assessment domain, NetApp emphasizes the creation of accurate and reusable documentation immediately after system installation. One of the supported tools for this purpose is NetAppDocs, which is designed to collect system configuration data and generate standardized inventory and design documentation. According to NetApp Storage Installation concepts and objectives, inventory reports must be produced in formats that support both technical review and customer handoff, while remaining editable and auditable.

NetAppDocs is explicitly described in NetApp documentation as supporting Microsoft Word, Microsoft Excel, and PDF outputs for inventory-style reports. These formats align with operational best practices defined in installation and assessment workflows. Word (.docx) files are used to present structured design narratives and annotated configuration details. Excel (.xlsx) files are used to present tabular inventory data such as controllers, disk shelves, ports, adapters, WWPNs, and LIF assignments, which are critical for SAN assessment and future expansion planning. PDF (.pdf) files are used as finalized, non-editable deliverables suitable for compliance records, customer signoff, and archival purposes.

Formats such as HTML and PostScript (.ps) are not identified in NetApp Storage Installation objectives as supported NetAppDocs inventory outputs. These formats do not align with NetApp’s standardized documentation deliverables and are not referenced in official installation or assessment documentation. As a result, they are excluded.

From a SAN-focused assessment perspective, the ability to generate Word, Excel, and PDF reports ensures consistency across deployment teams, simplifies validation of ONTAP SAN configurations, and supports accurate lifecycle documentation. These formats are repeatedly reinforced in NetApp installation guidance as the approved and supported inventory report outputs.

Therefore, the correct answers are A (.docx), C (.pdf), and E (.xlsx), as they are the only formats verified and supported for NetAppDocs inventory reporting within NetApp Storage Installation concepts and domains provided by NetApp.

Within the ONTAP SAN implementation and configuration domain,automatic port placementis a key installation feature designed to simplify initial network setup during cluster deployment. In ONTAP 9.8, when controller data ports are discovered, ONTAP automatically analyzes physical port connectivity, speed, and role, and assigns those ports to appropriatebroadcast domainsandsubnets.

Broadcast domains define Layer 2 boundaries and group ports that share the same network reachability. During installation, ONTAP automatically creates and assigns broadcast domains based on detected network topology and intended port usage. This behavior is explicitly described in NetApp installation objectives as part of reducing manual network configuration during initial setup.

Subnets are also automatically created and associated when automatic port placement is enabled. ONTAP uses subnets to manage pools of IP addresses for data LIF creation. By automatically configuring subnets, ONTAP enables rapid deployment of NAS and SAN data LIFs without requiring administrators to manually define IP address ranges during installation.

By contrast,routesare not automatically configured by automatic port placement. Routes must be explicitly defined by the administrator to control Layer 3 traffic flow between networks. Similarly,IPspacesare logical network containers that must be deliberately designed and created based on multi-tenancy or isolation requirements. IPspaces are never automatically created by ONTAP during installation because they have architectural implications that require administrator intent.

Therefore, the two ONTAP network settings that are automatically configured by automatic port placement arebroadcast domainsandsubnets, makingC and Dthe correct answers.

NS224 shelves are Ethernet-attached and connect through supported Ethernet switches. Additional capacity can be added either by attaching new NS224 shelves to the existing Ethernet fabric or by scaling out the cluster with additional AFF A400 nodes. NS224 shelves cannot be daisy-chained directly to other NS224 shelves, and dedicated storage switches are not required.

AFF A250 systems use25GbE ports with breakout cablingfor cluster and HA traffic. When adding these nodes to switches running a standard Cluster-HA RCF, the switches must be updated to aCluster-HA-Breakout RCFto support breakout ports. The nodes must then be cabled to the breakout ports. Therefore,B and Dare correct.

The AutoSupport history output shows multiple transport attempts usingSMTP, HTTP, and HTTPS, with SMTP being re-queued, HTTP ignored, and HTTPS failed. This indicates that AutoSupport is enabled and functioning at the configuration level, but the delivery mechanism is being blocked or restricted by the customer’s network infrastructure.

SMTP failures commonly occur when mail servers block large attachments or require explicit whitelisting of sending systems. Since full AutoSupport messages include large log bundles, mail servers often reject or delay these messages unless the sending nodes are explicitly allowed. Therefore,whitelisting the nodes on the mail serverdirectly addresses the SMTP delivery issue.

Additionally, NetApp installation best practices recommendHTTPS as the preferred AutoSupport transport protocolbecause it bypasses mail server limitations and is more reliable for large payloads. Switching the transport protocol to HTTPS avoids SMTP attachment-size restrictions entirely and ensures successful delivery when outbound HTTPS access is allowed.

Enabling AutoSupport on both nodes is not relevant because the output confirms AutoSupport is already active. Excluding nodes from attachment-size limits is not a supported ONTAP action.

Thus, the two correct actions are tochange the transport protocol to HTTPSandwhitelist the nodes on the mail server.

NetApp best practices allow mixing NAS protocols (NFS and CIFS) or SAN protocols (FCP and iSCSI) within the same SVM, but not mixing NAS and SAN.

AFF A250 systems use aconverged networking design, where the same physical ports are used for bothcluster interconnect traffic and HA interconnect traffic. This differs from older platforms that used dedicated HA interconnect ports.

The NetApp CN1610 switches only support10GbE, which is insufficient for AFF A250 systems. AFF A250 platforms require25GbE-capable cluster switchesto support both cluster and HA interconnect traffic.

Because the cluster ports are operational, the nodes can join the cluster. However, the HA interconnect traffic cannot be established due to insufficient switch capability, which explains why the NVRAM log cannot synchronize and the HA partner is unreachable.

Therefore:

The AFF A250requires switches with 25GbE port support

The AFF A250uses the same ports for cluster and HA interconnect

Statements involving 40GbE or separate HA ports are incorrect.

The correct answers areC and D.

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

NetApp hardware installation documentation strictly definessupported cable types and distancesfor Ethernet connectivity. For 40GbE connections using QSFP+ interfaces, NetApp supports both copper and optical cabling, each with specific distance limitations.

The exhibit shows supported copper cable options, including10-meter NetApp-supported copper cables, which exceed the current seven-meter requirement. Installing these supported cables is a valid and compliant solution.

Alternatively, the customer can change the requirement tooptical cables, which support significantly longer distances and are fully supported for AFF A400 40GbE connectivity. Optical cables are commonly used when distance exceeds passive copper limitations.

Relocating equipment is not required when supported cabling options exist. Changing “Ethernet cable requirements” generically is not a valid technical action.

Therefore, the correct answers areB and D.

To verify failover in a two-node ONTAP configuration, you must confirm both cluster-level HA state (for two-node clusters) and storage failover state (takeover/giveback readiness) for the HA pair.

The commandcluster ha showis used to verify the cluster HA status, which is especially relevant in two-node clusters where cluster HA can affect whether services remain available when one node is halted/rebooted. ONTAP documentation notes behaviors specific to two-node clusters and cluster HA, including the importance of proper HA configuration to avoid both nodes stopping data service under certain halt/reboot conditions.

The commandstorage failover showis the primary command to verify HA pair readiness, showing takeover/giveback capability, partner connectivity, and status indicators needed to confirm that storage failover is configured correctly.

Option C (cluster ring show) is a cluster database/ring status diagnostic command; while it can be useful in troubleshooting quorum or RDB-related issues, it is not the standard command pair for verifying HA failover configuration correctness after installation. Option D (storage failover show-takeover) is not the common baseline verification command cited for confirming general failover configuration; it is more takeover-output oriented rather than providing the full readiness overview that storage failover show provides.

Therefore, the two commands that accomplish correct failover verification in this scenario areA. cluster ha showandB. storage failover show.
