Provides decentralized, manual, and policy-driven IT resource management.

Q19. A Fibre Channel switch has eight ports and all ports must be operational from 8 AM to 8 PM, Monday through Friday. However, a failure of Port 2 occurs on a particular week as follows:
* Monday = 10 AM to 12 PM
* Wednesday = 4 PM to 9 PM
* Thursday = 4 PM to 7 PM
* Friday = 3 PM to 6 PM
* Saturday = 9 AM to 1 PM

70%

71.6%

78.3%

80%

Q20. What is the correct sequence of steps that need to be performed in storage system-based synchronous remote replication?

Q21. Match the Fibre Channel (FC) Layers with their respective functions.

Q22. Which file system uses a MapReduce framework to run applications and a NameNode for managing the file system?

New Technology File System (NTFS)

Hadoop Distributed File System (HDFS)

Network File System (NFS)

Common Internet File System (CIFS)

Q23. Which exhibit represents a Type 2 hypervisor?

Option A

Option B

Option C

Option D

Q24. Which compute system component enables dynamic extension of file system capacity and efficient storage management?

Logical Unit Number

Logical Unit Number Masking

Logical Volume Manager

Virtual Memory Manager

The evolution of LVMs enabled dynamic extension of file system capacity and efficient storage management.
The LVM provides optimized storage access and simplifies storage resource management. It hides details about the physical disk and the location of data on the disk. It enables administrators to change the storage allocation even when the application is running.

Q25. What is an activity in the risk assessment step of risk management?

Determine the likelihood of a risk

Plan and deploy security controls

Continuously observe the existing risks

Identify the sources of threats that increase the risks

Q26. A company plans to deploy a new application in their environment. The new application requires 5 TB of storage space. During peak workloads, the application is expected to generate 3000 IOPS with a typical I/O size of 3 KB. The capacity of each available disk drive is 750 GB. In addition, the maximum number of IOPS a drive can perform at with a 70% utilization is 90 IOPS.
What is the minimum number of disk drives needed to meet the application’s capacity and performance requirements for a RAID 0 configuration?

Q27. Which Dell EMC product creates a server and IP-based SAN from direct-attached server storage to deliver flexible and scalable performance and capacity on demand?
