Backup server instructs the storage node to load the backup media and backup clients to send the data to the storage node



Storage node sends metadata and media information to the backup server



Backup server retrieves backup-related information from the backup catalog



Storage node sends the data to the backup device

Match the storage type device with its description.

                 Storage Type                                            Device Description



Solid-state (flash) drive



Optical disc drive



Magnetic disk drive



Magnetic tape drive

A.

Stores data on a circular disk with a ferromagnetic coating




B.

Stores data on semiconductor-based memory




C.

Stores data on a thin plastic film with a magnetic coating




D.

Stores data on a polycarbonate disc with a reflective coating





50.

Which factors affect the recovery point objective (RPO) in a storage system-based asynchronous remote replication?



Type of replica volume and size of the buffer

Size of the source volume and distance between sites

Size of the replica volume and available network bandwidth

Size of the buffer and available network bandwidth


51.

What is the stripe size of a 5-disk RAID 5 group with a strip size of 32 KB?



96 KB

120 KB

128 KB

160 KB

Why do organizations prefer to adopt Disaster Recovery as a Service (DRaaS)?



Eliminate both CAPEX and OPEX in managing disaster recovery at remote sites

Avoid maintaining a complete set of IT resources in a remote data center for disaster recovery

Increase the effective utilization of hardware resources in their data centers

Understand and learn DRaaS best practices from service providers



53.

What is an advantage of sub-LUN tiering?



Enhanced reliability

Dynamic expansion of storage capacity

Improved performance

Faster provisioning of thin LUNs



54.

What happens when a disk fails in a RAID 5 array configured with a hot spare?



Reads continue from the hot spare but writes will fail

Both read and write operations cannot continue

Both read and write operations can continue

Array must be shut down immediately to replace the failed disk



55.

What is an accurate statement about a TCP offload engine (TOE) NIC with a software iSCSI adapter?



TCP/IP and iSCSI processing does not require the CPU cycles of a compute system

Offloads the iSCSI processing from the CPU of a compute system

TCP/IP and iSCSI processing requires the CPU cycles of a compute system

Offloads the TCP/IP processing from the CPU of a compute system



56.

What is an advantage of using a single-switch topology for a Fibre Channel (FC) SAN deployment?



Eliminates the need for ISLs when transferring FC frames

Requires a maximum of one switch port for ISL connectivity

Reduces the required number of ISLs when transferring FC frames

Increases the number of node ports for ISL connectivity

57.

An Ethernet switch has eight ports and all ports must be operational for 24 hours; from Monday through Friday. However, a failure of Port 2 occurs as follows:



  • Monday = 5 PM to 9 PM

  • Wednesday = 4 PM to 9 PM

  • Friday = 6 AM to 9 AM

  • Sunday = 9 AM to 1 PM

What is the MTBF of Port 2?

26 hours

36 hours

38 hours

40 hours


58.

What accurately describes a data lake in a big data environment?



Designed for query and analysis to support data decisions

Stores large volumes of structured and unstructured data collected from various sources

Designed to organize, classify, or analyze the data when it is created

Stores current and historical data that must have a structured format on object-based storage



59.

Which product delivers both Infrastructure as a Service and Platform as a Service to provide a consistent experience on-premise and in the public cloud?



Virtustream

Pivotal Cloud Foundry

Dell EMC Cloud for Microsoft Azure Stack

Dell EMC VxRack SDDC



60.

Which hypervisor component is responsible for assigning system resources to a virtual machine?



VNC

VMK

VMDK

VMM



61.

What is the function of MapReduce in big data analytics?



Provide a central repository of integrated data gathered from multiple different sources

Provide either a proprietary or an open-source distributed file system for client access

Identify and map a specific compute node to run big data computations

Enable the distribution of computations across multiple compute systems for parallel processing

62.

What is an accurate statement about Zoning?



Multiple zone sets may be defined in a fabric and all zone sets must be active at a time

Increases the amount of fabric-management traffic within a zone by sending RSCNs to all nodes in a fabric

FC switch ports, FC HBA ports, and storage ports should not be members of multiple zones

Nodes that are distributed across multiple switches in a switched fabric may also be grouped into the same zone


63.

Which object-based storage system feature provides self-configuring and self-healing capabilities to reduce complexity and downtime?



Multi-tenancy

Geo distribution

Metadata-driven policy

Automated system management
