39. Frage
Which StorageGRID feature enables you to have multiple active information lifecycle management (ILM) policies?
Antwort: B
Begründung:
The feature that enables multiple active ILM policies is ILM policy tags. NetApp StorageGRID allows administrators to create multiple ILM policies and associate each policy with a specific policy tag. Tenants can then assign one of those ILM policy tags to an S3 bucket, causing objects in that bucket to be managed by the ILM policy associated with the selected tag. This enables different buckets to receive different data- protection, placement, retention, or performance treatments while those policies remain active simultaneously.
StorageGRID also maintains a Default ILM policy tag. Every grid must have an active policy associated with the Default tag, and that policy governs objects in buckets that do not have another ILM policy tag assigned.
NetApp supports up to 10 policy tags per grid.
Option A is too general. Although StorageGRID implements the assignment on an S3 bucket, the enabling construct is specifically the ILM policy tag. Option C, multitenancy, separates tenant resources but does not itself permit multiple active ILM policies. Option D, IAM policy, controls S3 access permissions and authorization rather than ILM placement or retention behavior.
Therefore, B is the correct answer.

40. Frage
Your customer is working in a secure environment and will not allow the StorageGRID nodes to connect directly to the internet. The customer wants to take advantage of NetApp AutoSupport capabilities and automatic case creation.
How does the customer have to configure AutoSupport?
Antwort: B
Begründung:
The correct configuration is to route StorageGRID AutoSupport traffic through an Admin proxy server.
NetApp states that when AutoSupport packages are transmitted using HTTPS, the primary Admin Node requires outbound access to NetApp Technical Support either directly or through a proxy server. This is specifically intended for secure environments where StorageGRID nodes cannot establish unrestricted direct internet connections.
The administrator configures this under Configuration > Security > Proxy settings > Admin, enables the Admin proxy, and specifies the proxy server hostname or IP address and port. Authentication credentials can also be supplied when required. Once configured, AutoSupport traffic from Admin Nodes to NetApp Technical Support is routed through this controlled proxy path.
This preserves normal AutoSupport functionality, including periodic and event-triggered AutoSupport packages, which support proactive monitoring and automatic support-case workflows. Manually uploading bundles, as in A, would not provide the desired automated behavior. Option B does not solve the connectivity restriction. Option C is also incorrect because AutoSupport On Demand is intended primarily for active troubleshooting and itself requires HTTPS connectivity; it does not replace normal automated AutoSupport delivery.
Therefore, D provides the required secure outbound connectivity while retaining automated NetApp support capabilities.

41. Frage
You have implemented an Apache Kafka notification in Platform Services. You want to be notified in the event that Platform Services fails to send the data.
Using the storagegrid_platform_services_failed_kafka_notifications metric, which action enables you to receive notifications?
Antwort: C
Begründung:
The correct action is to create a custom alert rule that evaluates the
storagegrid_platform_services_failed_kafka_notifications Prometheus metric. StorageGRID collects operational metrics through Prometheus, and NetApp explicitly supports using those metrics as expressions in custom alert rules. When the configured expression crosses the defined threshold, StorageGRID generates an alert at the selected severity level.
For example, the administrator can create a rule under Alerts > Rules > Create custom rule and define an expression based on an increase or nonzero value for the failed Kafka notification metric. The alert can be configured with an appropriate duration and severity. Once triggered, StorageGRID can display the alert in Grid Manager and, when notification services are configured, send email or SNMP notifications to administrators.
Option B is incorrect because Grafana provides visualization of time-series metrics but does not itself establish StorageGRID alert notification logic. Option D allows an administrator to inspect or test the Prometheus metric, but merely querying it does not generate administrative notifications. Option A concerns HTTP/audit information and has no role in metric-based failure alerting.
Therefore, C is the required method for converting the Kafka failure metric into an actionable StorageGRID notification.

42. Frage
Consider a three-site StorageGRID deployment with three Storage Nodes per site. The consistency level for a bucket is set to strong-global.
Which two statements explain the read and write behavior on this bucket? (Choose two.)
Antwort: B,C
Begründung:
Under the legacy strong-global consistency behavior represented by these answer choices, writes use a quorum of metadata replicas at every site, while reads require a quorum of metadata replicas at the local site.
Consequently, B and D are the intended answers. This architecture provides read-after-write consistency across all sites while allowing a client to perform reads using the metadata replicas available locally rather than waiting for responses from every remote site. NetApp defines strong-global as guaranteeing read-after- write consistency for client requests across all sites.
There is an important StorageGRID 12.0 qualification. New StorageGRID 12.0 installations use Quorum strong-global semantics by default. In a three-site grid containing three metadata replicas per site, the write requirement becomes a grid-wide quorum of five of the nine metadata replicas, with no more than three replicas contributed by one site. This improves site-failure tolerance. Systems upgraded from StorageGRID
11.9 or earlier retain the legacy strong-global behavior unless explicitly changed.
Therefore, B and D are the certification-key answer for the semantics assumed by this question, but B should not be generalized to a newly installed StorageGRID 12.0 grid using Quorum strong-global.

43. Frage
In your extensive StorageGRID deployment, you want to configure a custom alert that notifies you when the CPU utilization of any node exceeds 90% and the node's memory utilization surpasses 80%.
What do you use to define this condition?
Antwort: A
Begründung:
StorageGRID custom alert rules define their trigger conditions using Prometheus expressions. NetApp StorageGRID 12.0 documentation states that when creating a custom alert rule, the administrator enters a Prometheus expression for one or more alert severity levels. These expressions evaluate metrics collected from StorageGRID nodes and services and determine when an alert condition becomes true.
For this requirement, the administrator would construct an expression that evaluates both CPU and memory utilization metrics and combines the conditions logically so that the rule triggers only when CPU usage exceeds 90% and memory utilization exceeds 80% for the same applicable node. StorageGRID's Prometheus service collects time-series metrics from services throughout the grid, and those metrics are used by both the Grid Manager monitoring views and the alerting framework.
Option A is incorrect because the Grid Management REST API can expose metrics and can be used to test Prometheus queries, but it is not the syntax used to define the alert condition itself. Option B is an S3 object- query capability and is unrelated to system monitoring. Option C is not the alert-expression language.
Therefore, D. Prometheus expression is the correct answer.
