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
|

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

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?
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
|
