EMC D-ISM-FN-23 - Dell Information Storage and Management Foundations 2023 Exam

Using a service-focused approach allows the storage infrastructure to be managed based on the needs of the business or customers. This approach focuses on the delivery of services, rather than just the management of storage components or devices. When a service provisioning request is received, the service-focused approach provides a framework to determine the appropriate workflow to fulfill that request. This may include provisioning additional storage resources, modifying existing configurations, or other tasks to meet the service level agreements (SLAs) of the business or customer. Reference: Section 1.3 Service-Oriented Storage Provisioning, page 16.

Calculate the total downtime for Port 5:

Monday: 11 AM to 3 PM = 4 hours

Thursday: 6 AM to 11 AM = 5 hours

Saturday: 11 AM to 4 PM = 5 hours

Total downtime = 4 + 5 + 5 = 14 hours

Calculate the total number of hours in a week:

7 days * 24 hours = 168 hours

Calculate the uptime for Port 5:

Total uptime = Total hours in a week - Total downtime

Total uptime = 168 hours - 14 hours = 154 hours

Calculate the availability:

Availability = (Total uptime / Total hours in a week) * 100

Availability = (154 / 168) * 100 ≈ 91.6%

Therefore, the availability of Port 5 in that week is approximately 94.6%.

Encryption is the security control mechanism that helps to secure data during replication over a public network to a cloud. By encrypting data, it ensures that even if the data is intercepted during transmission, it cannot be read or tampered with by unauthorized parties. Encryption algorithms transform the data into a secure format that can only be decrypted by authorized users with the correct decryption key, thereby protecting the data's confidentiality and integrity.References:= Dell Information Storage and Management V5 course materials

Capacity Requirement: 5 TB = 5000 GB

Disk Capacity: 750 GB

Number of Disks for Capacity:Capacity Disks=⌈5000750⌉=7 disksCapacity Disks=⌈7505000​⌉=7 disks

Performance Requirement: 3000 IOPS

Disk IOPS: 90 IOPS (at 70% utilization)

Number of Disks for Performance:Performance Disks=⌈300090⌉=34 disksPerformance Disks=⌈903000​⌉=34 disks

Final Number of Disks: The higher of the two values is needed, which is 34 disks.

Governance is a practice of creating and enforcing policies that guide an organization in how it should be managed and operated. This includes developing strategies, setting operational rules, and making decisions that direct how an organization should be run. It is important to note that governance is not limited to only IT-related matters, as it encompasses all aspects of the organization, from financial to personnel management.

To calculate the availability of Port 7, we need to determine the total downtime during the specified operational hours and the total operational hours for the week.

Total operational hours:

Monday to Friday: 12 hours/day * 5 days = 60 hours

Total downtime during operational hours:

Monday: 1 hour (11 AM to 12 PM)

Wednesday: 5 hours (4 PM to 9 PM)

Thursday: 0 hours (4 AM to 9 AM is outside operational hours)

Friday: 4 hours (2 PM to 6 PM)

Saturday: 0 hours (Saturday is outside operational hours)

Total downtime = 1 + 5 + 4 = 10 hours

Total available hours= 60 hours - 10 hours = 50 hours

Availability= (Total available hours / Total operational hours) * 100Availability=(5060)×100=83.3%Availability=(6050​)×100=83.3%
