An organization is planning to adopt pre integrated systems to deploy compute, network, storage, and management functions as a single engineered solution.
Which approach should the organization adopt?

  1. Service based approach
  2. DIY approach
  3. Vendor ready solutions
  4. DCaaS solution

Answer(s): C

Explanation:

Pre-integrated systems are vendor-provided solutions that combine compute, network, storage, and management functions as a single engineered solution. This approach is also known as a converged infrastructure or a hyper-converged infrastructure. The vendor provides pre-configured, pre-tested hardware and software components that work together seamlessly. The pre-integrated system reduces the complexity of building and deploying IT infrastructure, while also improving performance, scalability, and reliability. This approach is different from a DIY (do-it-yourself) approach, where an organization builds its infrastructure from individual components, and a DCaaS

(Data Center as a Service) approach, where the organization outsources its entire data center to a third-party provider.

Section 1.7 Converged Infrastructure, page 62.



Why is it important to automate the operations management process in a data center environment?

  1. converts CAPEX to OPEX
  2. mitigates operation management risks
  3. eliminates operational cost
  4. ensures operational agility

Answer(s): B

Explanation:

Automating the operations management process in a data center environment can help mitigate operational management risks. Automation can reduce the likelihood of human error, which can lead to outages or other disruptions. By automating routine tasks, such as patch management, configuration updates, and resource allocation, IT staff can focus on higher-value activities that drive innovation and improve the user experience. Additionally, automation can improve operational efficiency, reduce costs, and ensure operational agility, but it does not eliminate operational costs.

Section 2.6.2 Automation of IT Operations, page 127.



An Ethernet switch has eight ports and all ports must be operational for 24 hours from Monday through Friday.
However, a failure of Port 7 occurs as follows:
Monday=4 PM to 11 PM
Wednesday= 2 PM to 10 PM
Friday= 5 AM to11 AM
What is the MTTR of Port 7?

  1. 36 hours
  2. 5 hours
  3. 7 hours
  4. 33 hours

Answer(s): C

Explanation:

To calculate MTTR, we need to convert the hours into minutes. Here are the steps:
Monday: Port 7 was down from 4 PM to 11 PM. That's 7 hours or 420 minutes. Wednesday: Port 7 was down from 2 PM to 10 PM. That's 8 hours or 480 minutes. Friday: Port 7 was down from 5 AM to11 AM. That's 6 hours or 360 minutes. Total corrective maintenance time = 420 + 480 + 360 = 1260 minutes Number of repairs = 3

MTTR = Total corrective maintenance time / Number of repairs MTTR = 1260 / 3 = 420 minutes
Therefore, the MTTR of Port 7 is 420 minutes.



A host sends one write /O to the RAID 1 array.
How many writes does it take for the array to store the data?

  1. Six write 1/Os
  2. Four write I/Os
  3. Two write I/Os
  4. One write I/Os

Answer(s): C

Explanation:

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.
