NEW QUESTION # 79
To protect against an on-site disaster, which NetApp protection method should an administrator use to provide a Zero RTO for applications in a SAN environment?
Answer: C
Explanation:
SnapMirror active sync is the ONTAP data-protection technology designed to provide Zero Recovery Time Objective for business-critical SAN applications. It synchronously replicates protected application data between ONTAP clusters and uses host multipathing plus ONTAP Mediator-assisted automatic failover so that application access can continue when the primary storage system or site becomes unavailable. NetApp explicitly describes SnapMirror active sync as providing Zero RTO or Transparent Application Failover for SAN environments. SnapMirror asynchronous cannot provide Zero RTO because replication is not continuously synchronous and recovery requires a failover workflow. SnapMirror SVM and FlexClone LUNs also do not provide the same automatic, synchronous application failover behavior. Relevant SAN ONTAP topics are SnapMirror active sync, synchronous replication, consistency groups, ONTAP Mediator, automatic failover, and SAN business continuity.
NEW QUESTION # 80
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)
Answer: C,D
Explanation:
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
* Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
* Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I
/O operations and performance degradation.

NEW QUESTION # 81
What will enable iSCSI multipathing on a new Windows Server 2022?
Answer: D
Explanation:
NetApp Windows Host Utilities are used to configure Windows hosts correctly for ONTAP SAN storage and include support for Microsoft Multipath I/O configuration. During Host Utilities installation, multipathing support can be selected when multiple paths exist between the Windows server and the storage system. The package also configures required Windows registry and storage parameters so the host correctly handles ONTAP pathing behavior. Device Mapper Multipathing is primarily associated with Linux and is therefore inappropriate for Windows Server. An iSCSI target represents the storage endpoint and does not itself configure host multipathing. ANA is the NVMe multipathing mechanism and does not apply to an iSCSI LUN. Relevant SAN ONTAP topics include Windows Host Utilities, Microsoft MPIO, iSCSI host configuration, ALUA, redundant SAN paths, and Windows Server interoperability.
NEW QUESTION # 82
An administrator connects to a LUN from Node A to a host in a redundant pathing configuration.
How does the administrator show that the LUN delivers data if a node disruption occurs?
Answer: A
Explanation:
A controlled storage takeover and giveback is the appropriate method for validating HA behavior without deliberately creating uncontrolled infrastructure failures. NetApp recommends testing an HA pair after configuration to verify uninterrupted access to storage during takeover and giveback. During takeover, the surviving HA partner assumes responsibility for the affected node ' s storage and continues serving its data.
Host multipathing redirects SAN I/O through surviving paths. Giveback subsequently returns storage ownership and processing to the home node. Pulling cluster-interconnect cables, removing rack power, or disabling backend connectivity introduces unnecessary failure conditions and can affect more infrastructure than required for a controlled validation. Therefore, performing takeover and giveback on the nodes verifies both storage-controller failover and the host ' s redundant SAN path configuration.
NEW QUESTION # 83
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
Answer: A
Explanation:
To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to support multiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.
