DES-1D12 Online Practice Questions and Answers

Correct Answer: A

The Dell PowerStore supports a variety of media devices, including NVMe SCM, NVMe SSD, SAS SSD, SAS HDD, and NVRAM. Of these, NVMe SCM, NVMe SSD, and SAS SSD carry a FIPS Type D certification. This certification is a Federal Information Processing Standards (FIPS) certification that indicates that the device has passed a set of security standards established by the US government for use in sensitive, but unclassified data.

Correct Answer: C

Dell Unity XT MetroSync replication topology is a multi-site replication solution that allows you to replicate data synchronously between two or more Unity XT systems. In this topology, a source file resource is replicated synchronously from Site A to Site B, and also replicated synchronously from Site A to Site C. This means that data is written to the primary site and immediately replicated to the secondary site, ensuring that both sites have an exact copy of the data at all times. This type of topology is useful in cases where data loss is not acceptable and a zero RPO is needed. This topology ensures that the data is fully protected and that the environment is highly available, as in case of a primary site failure, the secondary site can take over.

Correct Answer: D

The embedded module in a Dell Unity XT 480F system provides management functionality for the system, such as control of the storage array, monitoring of system health and performance, and management of storage resources. This embedded module allows you to manage the system through an intuitive web-based interface or via command-line interface.

Correct Answer: B

A storage container is used to present vVol storage from a PowerStore cluster to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. When a PowerStore cluster is used to provide VM storage, user VMs should be provisioned on the vVol datastores. The default storage container is mounted automatically on the nodes of the cluster.

Correct Answer: C

Based on the customer's monthly data access profile, where block data is accessed infrequently but frequently during month-end reporting, the technical architect should recommend a hybrid solution using FAST VP and FAST Cache. FAST VP (Fully Automated Storage Tiering for Virtual Pools) is a feature that automatically tiers data across different types of storage media based on access patterns. With FAST VP, frequently accessed data will be automatically moved to faster storage media such as flash, while infrequently accessed data will be moved to slower, less expensive storage media such as disk. FAST Cache is a feature that increases the performance of Unity storage systems by caching frequently accessed data on flash storage. With this hybrid solution, the customer will have the best of both worlds: high-performance flash storage for frequently accessed data, and lower-cost disk storage for infrequently accessed data. This will help the customer to improve performance during month-end reporting and save costs for infrequently accessed data. It's important to note that this design should be evaluated based on the specific requirements, workloads and expected growth of the customer.

Correct Answer: D

This ensures that the drive is properly connected and communicating with the array, and that it is functioning as expected. Additionally, the new drive should be added to an existing DRS(Drive Replacement Set) and if necessary, the keystore should be backed up and the drive should be formatted.
