Question 1

What is a function of the metadata service in an object-based storage device (OSD)?

AGenerates the file system namespace from the file contents.

BManages both physical and logical disks on which the user data is stored.

CManages the storage space for all remote clients.

DMaintains the object IDs and file system namespace mappings.

Answer : D

Question 2

A host sends one write /O to the RAID 1 array.

How many writes does it take for the array to store the data?

ASix write 1/Os

BFour write I/Os

CTwo write I/Os

DOne write I/Os

Answer : C

In a RAID 1 array, data is mirrored across two disks. So when a host sends one write I/O to the array, the array will perform two write I/Os to store the data on both disks. The other options are incorrect because they do not accurately reflect the number of write I/Os required in a RAID 1 array.

Question 3

What statement describes machine learning?

AApplies an algorithm to large amounts of data for pattern discovery

BOrganizes data efficiently so that compute systems can learn

CDeveloping a program to compute every possible outcome

DReplicating a detailed process and then implementing it in software

Answer : A

Machine learning is a subfield of artificial intelligence that gives computers the ability to learn without explicitly being programmed[1]. It does this by applying an algorithm to large amounts of data in order to discover patterns and insights that can be used to inform decisions and predictions. This allows machines to learn from experience and make decisions in a way that mimics the human brain.

Question 4

Which statement is true regarding virtual provisioning?

AShared and Thin LUNS can be expanded rapidly with only minor disruptions

BMultiple shared storage pools can be created while each pool must be allocated to a unique thin LUN

CVirtual provisioning enables more efficient allocation of storage to compute systems

DVirtual provisioning prevents issues that arise from oversubscription

Answer : C

Virtual provisioning is a storage management technique that enables more efficient allocation of storage to compute systems. It allows storage administrators to create virtual storage resources that are presented to compute systems as if they were physical resources, even if the physical storage capacity does not exist. Virtual provisioning supports various types of virtual storage, including thin LUNs and thin clones. Thin LUNs enable shared and rapid expansion with only minor disruptions. Multiple shared storage pools can be created, and each pool can be allocated to multiple thin LUNs. However, virtual provisioning does not prevent issues that arise from oversubscription; it is important to monitor and manage capacity utilization to avoid performance degradation or service disruptions. Reference: Section 2.5.1 Virtual Provisioning, page 107.

Question 5

What is the result of increasing the number of FC switches in a full mesh topology?

AReduces available node ports for ISL connectivity

BReduces number of storage and compute ports for node connectivity

CReduces switch ports available for node connectivity

DReduces switch ports available bandwidth for node connectivity

Answer : C

Question 6

Why is it important for organizations to implement a multi-site remote replication solution?

AEnsure data protection is always available if there are any single site failures

BProvide consistent near-zero RPO in the event of source and remote site failures

CPerform synchronous replication with low network bandwidth

DRecover data to any point-in-time in the event of a remote site failure

Answer : B

Question 7

What is a purpose of the policy engine in a data archiving environment?

AFacilitates manual searching for archived data in archive storage

BMoves the appropriate data into archive storage automatically

CAutomates the process of identifying the data to move from archive to primary storage

DEnables manual migration of older archived data between archive storage devices

Answer : B

The purpose of the policy engine in a data archiving environment is to automate the process of moving the appropriate data from primary storage into archive storage. It does this by monitoring data access patterns in primary storage and automatically moving the data that is least accessed into an archive storage device. This process allows for more efficient use of primary storage and also reduces storage costs.
