Network Appliance NetApp StorageGRID Administrator Exam 認定 NS0-077 試験問題 (Q55-Q60):

質問 # 55
A new application has been installed in your company that requires objects to be converted to another format immediately after they are placed in a specific bucket.
Which two endpoints notify the application? (Choose two.)

A. an Apache Kafka endpoint to send an event to the application after a new object is placed in the bucket
B. a webhook endpoint to notify the application that a new object has been placed in the bucket
C. a specific load balancer endpoint for this application
D. a CloudMirror endpoint, so the application can use this mirrored object after a new object is placed in the bucket

正解：A、B

質問 # 56
Which scenario is a use case for utilizing bucket branches in NetApp StorageGRID?

A. creating temporary, isolated copies of a production bucket's data and metadata for nondisruptive testing, development, or quality assurance purposes
B. allowing a single S3 bucket to be simultaneously accessed using multiple protocols (for example, S3, NFS, and SMB) from different client types
C. automatically tiering data from a hot, on-premises bucket to a public cloud cold storage service based on predefined access patterns, to reduce costs
D. configuring complex information lifecycle management (ILM) rules that apply different retention and placement policies to specific object prefixes within the same bucket

正解：A

解説：
A StorageGRID branch bucket provides access to objects from a versioned base bucket as those objects existed at a selected point or range in time. NetApp describes a branch bucket as presenting a distinct view of protected data while allowing operations on the branch to be separated from the base bucket. This makes branch buckets appropriate for use cases such as application testing, investigation, recovery workflows, development, and other activities where production data should remain undisturbed.
When creating the branch, an administrator can select a Before, After, Between, or Exclude time filter. A branch can also be configured as read-only or read-write. Importantly, object settings and objects written directly to a branch do not modify the corresponding object versions in the base bucket.
Option A is incorrect because StorageGRID is fundamentally S3 object storage; branch buckets do not provide simultaneous SMB/NFS access. Option B describes cloud tiering rather than branching. Option C describes ILM rule filtering and placement behavior, which is handled through StorageGRID ILM policies and rules, not branch buckets.
Therefore, D best represents the intended operational purpose of branch buckets: creating an isolated point-in- time data view for nondisruptive work without changing the production base bucket.

質問 # 57
Which encryption method is available for all deployment methods?

A. Drive Encryption
B. Stored Object Encryption
C. Drive Security
D. Node Encryption

正解：B

解説：
Stored Object Encryption is the StorageGRID encryption method that is available regardless of how the grid nodes are deployed. It is configured centrally in Grid Manager rather than depending on appliance-specific hardware capabilities. When enabled, StorageGRID encrypts newly ingested S3 object data that has not already been encrypted at the bucket or object level. StorageGRID supports AES-128 or AES-256 for this function.
The other options are deployment-specific. Node Encryption is associated with StorageGRID appliance nodes and a configured external Key Management Server (KMS); it must be enabled for an eligible appliance during installation. Drive Security depends on storage appliances equipped with Full Disk Encryption or self- encrypting drives and is managed through SANtricity System Manager. Drive Encryption likewise requires StorageGRID appliances containing supported self-encrypting drives and is configured through the StorageGRID Appliance Installer. These hardware dependencies mean none of those three methods is universally available across virtual, containerized, cloud, and appliance deployment models.
Therefore, C. Stored Object Encryption is the correct answer because it operates at the StorageGRID object- ingest layer rather than relying on a particular node or disk hardware implementation.

質問 # 58
A customer wants to test their application against a StorageGRID system to verify its compatibility.
What is the minimum number and type of nodes required to deploy a healthy virtual StorageGRID environment for this test?

A. four - Admin Node, Storage Node, Storage Node, Storage Node
B. five - Gateway Node, Admin Node, Storage Node, Storage Node, Storage Node
C. three - Storage Node, Storage Node, Storage Node
D. two - Admin Node, Storage Node

正解：A

解説：
A healthy StorageGRID deployment requires one primary Admin Node and at least three Storage Nodes at each site. NetApp StorageGRID 12.0 documentation states that every grid requires a primary Admin Node to provide core management and configuration services, while every site requires a minimum of three Storage Nodes. Therefore, the smallest healthy single-site virtual test environment contains four nodes: one Admin Node plus three Storage Nodes.
The three-Storage-Node minimum is important because Storage Nodes host core distributed services such as Cassandra, DDS, and ADC. In particular, the ADC service is hosted on at least three Storage Nodes at a site, supporting grid topology information, authentication, and service discovery.
Option A lacks the required primary Admin Node and therefore cannot constitute a complete manageable StorageGRID grid. Option D contains an Admin Node but only one Storage Node, which does not satisfy the three-node minimum. Option C would work, but the Gateway Node is optional because Admin Nodes can also provide S3 load-balancing functionality for a small compatibility-test deployment.
Therefore, B is the minimum healthy virtual configuration.

質問 # 59
You are configuring a two-site StorageGRID solution to be the destination for mission-critical application data. You want the HA group to fail over from one site to the other in the event of a site failure.
How is the HA group configured?

A. Enter a fully qualified domain name (FQDN) for the virtual IP address.
B. Enter a gateway IP address for the virtual IP address.
C. Enter a virtual IP address in a subnet that spans all sites in the virtual IP address list.
D. Enter a unique IP address for each site in the virtual IP address list.

正解：C

解説：
A StorageGRID High Availability (HA) group provides active-backup access by assigning one or more virtual IP (VIP) addresses to the currently active interface. For site-level failover, the HA group includes suitable Admin Node or Gateway Node interfaces from both sites, and those interfaces must participate in a network design that allows the same VIP to move between sites. NetApp's StorageGRID site-failover guidance specifically describes including interfaces from Site 1 and Site 2 and assigning a VIP within the same subnet. If the preferred site's interface becomes unavailable, StorageGRID transfers the VIP to the next available interface at the other site.
Accordingly, the VIP subnet must be available across the participating sites; the same client-facing VIP remains usable after failover. StorageGRID requires the VIP and optional gateway to belong to the configured VIP subnet.
Option B is incorrect because multiple VIPs are not assigned as independent site-specific addresses for HA failover; all configured VIPs reside simultaneously on the active HA interface. Option C is invalid because the HA configuration requires IP addresses, not an FQDN. Option D confuses the optional gateway with the actual VIP.
