A customer wants to replicate data between Azure NetApp Files volumes in different regions. Which replication method should the customer use?
When replicating data between Azure NetApp Files volumes in different regions, the appropriate replication method is asynchronous replication. Asynchronous replication is commonly used for geo-replication across regions to ensure data is copied between regions, providing disaster recovery capabilities while allowing some latency in data synchronization.
Synchronous (D) replication is typically used for high-availability within the same region or low-latency environments. Bidirectional (A) and semi-synchronous (B) are not applicable or commonly used terms in Azure NetApp Files replication scenarios.
A customer has 100TB of used capacity after efficiencies on an on-premises AFF volume. There is a requirement to tier cold data to Amazon Simple Storage Service (Amazon S3) with BlueXP tiering. There is also a requirement to back up the data with BlueXP backup and recovery to Amazon S3. After enabling tiering, 80% of cold data is tiered, then the first full backup is completed.
What is the total ingress traffic into AWS?
In this scenario, the customer has 100TB of used capacity on an on-premises AFF volume, and 80% of the data is cold and tiered to Amazon S3 using BlueXP tiering. After tiering, 80TB of cold data is tiered to Amazon S3, leaving 20TB of hot data on the AFF system. When BlueXP backup and recovery performs the first full backup, it backs up all the data (100TB). Since the backup is a full copy and independent of the tiering process, the total ingress traffic into AWS is 80TB (tiered data) + 100TB (full backup), resulting in 180TB of total ingress.
A customer is implementing NetApp StorageGRlD with an Information Lifecycle Management (ILM) policy. Which key benefit should the customer expect from using ILM policies in this solution?
NetApp StorageGRID's Information Lifecycle Management (ILM) policies offer the key benefit of automated data optimization. ILM policies enable the system to automatically manage data placement and retention across different storage tiers and locations based on factors such as data age, usage patterns, and performance requirements. This ensures that frequently accessed data is placed on high-performance storage, while older or less critical data can be moved to lower-cost storage, optimizing resource use and reducing costs.
While ILM policies can contribute to improved data security (A) and simplified data access controls (D), their primary focus is on optimizing data storage over its lifecycle. Real-time data analytics capabilities (C) are not a core feature of ILM policies.
A company wants to save on AWS infrastructure costs for NetApp Cloud Volumes ONTAP. They want to tier to Amazon Simple Storage Service (Amazon S3).
What is the best way for the company to create a connection to S3 without incurring egress charges?
When setting up NetApp Cloud Volumes ONTAP to tier to Amazon S3, minimizing infrastructure costs, especially egress charges, is critical. The best way to create a connection to S3 without incurring egress charges is by using an AWS gateway endpoint.
Gateway endpoints enable a private connection between Amazon S3 and your Amazon Virtual Private Cloud (VPC), eliminating the need for internet-based routing, which would incur data transfer charges (egress fees). With this private connection, data is transferred directly between the VPC and S3 without crossing the public internet, thus avoiding egress costs.
Other options such as peering and PrivateLink are viable for connecting VPCs but do not specifically address the elimination of egress charges when connecting to S3. A NAT device is also unnecessary for this scenario and would not eliminate egress charges but could instead introduce additional costs. Therefore, the gateway endpoint is the most cost-effective and direct method for achieving the desired outcome.
A company experienced a recent security breach that encrypted data and deleted Snapshot copies. Which two features will protect the company from this breach in the future? (Choose two.)
To prevent security breaches like the one experienced by the company, where data was encrypted and Snapshot copies were deleted, two features are essential:
SnapLock (A): SnapLock is a feature that provides write once, read many (WORM) protection for files. It prevents the deletion or modification of critical files or snapshots within a specified retention period, even by an administrator. This feature would have protected the company's Snapshot copies by locking them, making it impossible to delete or alter them, thus preventing data loss during a ransomware attack.
Multi-Admin Verification (D): This feature requires approval from multiple administrators before critical operations, such as deleting Snapshots or making changes to protected data, can proceed. By requiring verification from multiple trusted individuals, it greatly reduces the risk of unauthorized or malicious actions being taken by a single user, thereby providing an additional layer of security.
While Snapshot technology (C) helps with regular backups, it doesn't protect against deliberate deletion, and Data Lock (B) is not a NetApp-specific feature for protecting against such breaches.
