NEW QUESTION # 31
Your customer is a service provider that wants to host static images for multiple customer websites in different domains, but from a single DNS endpoint. All traffic must be HTTPS encrypted to ensure security and validity of content.
What do you configure to prevent error messages?
Answer: D
Explanation:
The correct configuration is Cross-Origin Resource Sharing (CORS). StorageGRID supports CORS specifically so that objects stored in an S3 bucket can be accessed by web applications originating from different domains. NetApp's documentation uses essentially this exact use case: an S3 bucket containing images can be configured with CORS so that those images can be displayed by a website hosted in another domain.
For a service provider hosting image objects centrally while multiple customer websites access those objects from separate domains, the browser treats the requests as cross-origin. A CORS configuration on the S3 bucket defines the permitted origins, HTTP methods such as GET, and allowed headers. The administrator can either authorize specific customer domains or, where appropriate, permit GET requests from multiple origins. HTTPS remains handled independently by the StorageGRID load balancer endpoint and its TLS certificate.
Option C is incorrect because the HTTPS certificate must match the StorageGRID endpoint domain names clients connect to, not every external website that merely references the images. Option A is unnecessary because one endpoint can service multiple domains, and Swift is unrelated.

NEW QUESTION # 32
A user is having an issue deleting a version of an object in a bucket that they are working with.
What must the user check to see if they have the correct permissions?
Answer: C
Explanation:
To delete a specific version of an S3 object, the user must have the appropriate S3 permission, specifically s3:
DeleteObjectVersion. In StorageGRID, permissions granted to tenant users are commonly defined through group policies, which control which S3 actions members of the group are authorized to perform against specified bucket and object resources. NetApp explicitly maps s3:DeleteObjectVersion to the S3 operation that deletes a specific object version.
Therefore, the user should verify the group policy associated with their tenant account and confirm that it allows s3:DeleteObjectVersion for the required bucket or object ARN. An explicit Deny for this action would override an Allow. NetApp even provides policy examples that specifically restrict users from deleting versioned objects by denying s3:DeleteObjectVersion.
Option B is incorrect because an S3 lifecycle policy automates object expiration and version-management behavior; it does not grant interactive user permissions. Option C governs where and how StorageGRID stores and protects object data, not S3 authorization. Option D refers to administrative privileges and is not the standard mechanism controlling a tenant user's object-level S3 operations.
Therefore, A. group policy is correct.

NEW QUESTION # 33
Which statement about controlling access with group policies is true?
Answer: C
Explanation:
In StorageGRID, group policies are attached to a specific tenant group and define which S3 resources members of that group are permitted or denied access to. NetApp explicitly states that a group policy applies to only one group and can apply to multiple buckets. This makes B the correct answer.
Group policies are configured through Tenant Manager or the Tenant Management API and use AWS- compatible JSON policy syntax. A single group policy can therefore contain multiple Resource entries referencing different buckets and objects. In contrast, a bucket policy is attached to one specific bucket and can grant or deny access to multiple users or groups.
Options A and C are incorrect because StorageGRID does not assign precedence among group, bucket, and session policies. NetApp states that there is no difference in priority among these policy types. Authorization is determined by evaluating the applicable policy statements, with an explicit Deny overriding an Allow; it is not based on one policy class automatically taking precedence over another.
Option D reverses the relationship: it describes the scope of a bucket policy rather than a group policy.

NEW QUESTION # 34
An enterprise is expanding a single-site StorageGRID deployment and is adding new nodes on a new subnet.
What is a requirement for configuring the Grid Network?
Answer: C
Explanation:
When an existing StorageGRID deployment is expanded with nodes whose Grid Network IP addresses are on a subnet that has not previously been used, that subnet must be added to the Grid Network subnet list before the expansion is started. StorageGRID maintains this list so that every grid node can correctly route internal Grid Network traffic to the other participating subnets. NetApp StorageGRID 12.0 documentation explicitly states that if any new node uses a new Grid Network subnet, the administrator must add that subnet first; otherwise, the expansion must be cancelled, the subnet added, and the expansion restarted.
The configuration is performed in Grid Manager # Maintenance # Network # Grid Network, where the administrator selects Add another subnet and enters the network in CIDR notation. StorageGRID then distributes the routing configuration throughout the grid.
Option A is incorrect because routes do not need to be configured manually on every node. Option B is incorrect because a StorageGRID Gateway Node provides client load-balancing functions and is not an IP router between Grid Network subnets. Option D is also incorrect; StorageGRID explicitly supports multiple Grid Network subnets, provided they are routable through the configured Grid Network gateway.

NEW QUESTION # 35
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?
Answer: D
Explanation:
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.
