EMC EMC Certifications DES-1D12 Questions & Answers

• Question 61:

  Which path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type?

  A. Application Oriented

  B. Data Input

  C. Quick Configuration

  D. System Designer

  Correct Answer: D

  The System Designer path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type. This path is designed to make the sizing process quick and easy, providing recommended configurations that are optimized for specific array models and workloads. It allows the user to select an array model, and then it will provide a set of predefined configurations that meet the desired capacity, performance, and availability requirements.

• Question 62:

  How does configuring snapshot retention differ when manually creating snapshots in the Dell EMC Unity GUI, compared to using the Unity CLI?

  A. Manually created snapshots do not have the `No automatic deletion' option. Snapshots created with Unity CLI have the `No automatic deletion' option.

  B. Manually created snapshots have the `No automatic deletion' option. Snapshots created with Unity CLI do not have the `No automatic deletion' option.

  C. The retention period for manually created snapshots is days. The retention period for snapshots created with Unity CLI can be hours or days.

  D. The retention period for manually created snapshots can be hours or days. The retention period for snapshots created with Unity CLI is days.

• Question 63:

  A technical architect is designing a Dell Unity XT 480 using the System Designer option of Sizer. What is the recommended minimum amount of Flash that they should specify?

  A. 15%

  B. 7%

  C. 5%

  D. 10%

  Correct Answer: B

  7% is the recommended minimum amount of Flash that a technical architect should specify when designing a Dell Unity XT 480 using the System Designer option of Sizer. This is because, Unity XT storage systems require a certain amount of flash storage to handle system-wide functions such as metadata, snapshots and other storage services.

• Question 64:

  An ISP needs a data storage solution that allows them to set policies over resource usage. The solution needs to support network multi-tenancy while also providing full network failover protection. What combination of Dell EMC SC Series features meets these requirements?

  A. Thin Replication and Storage Profiles

  B. VLAN Tagging and QoS

  C. Multi-protocol and Live Volume

  D. Replication and vVols

  Correct Answer: C

• Question 65:

  Which CPU family is used on a Dell Unity XT 480?

  A. ice Lake

  B. Haswell

  C. Skylake

  D. Broadwell

  Correct Answer: C

  The Skylake CPU family is a 6th generation Intel processor, which provides higher performance and improved energy efficiency compared to its predecessors. It is used on the Dell Unity XT 480, as well as other systems such as the Dell XPS 13, MacBook Pro, and HP Envy. Skylake CPUs are also used in servers, desktops, and laptops. Skylake CPUs include features such as Turbo Boost, Hyper-Threading, and support for DDR4 memory.

• Question 66:

  When a remove replication operation is performed on a Dell EMC PowerStore array, what happens to the destination storage resource?

  A. Is deleted

  B. Stays in read/write mode

  C. Stays in read-only mode

  D. Taken offline

  Correct Answer: C

  "Removing a replication session is initiated on the source system by removing the protection policy from the Volume or Volume Group on the source system. Removing the protection policy from a storage resource results in the following: * The destination storage resource stays in read-only mode."

• Question 67:

  When sizing a Dell EMC Unity Hybrid array, what are considerations for performance?

  A. Workload and hardware bottlenecks

  B. Active data and load balancing

  C. Drive size and component redundancy

  D. General capacity and port utilization
