IBM Certified Data Architect - Big Data Certification Questions and Answers (Dumps and Practice Questions)

Question : Which of the following statements is TRUE regarding IAAS vs PAAS?

1. Performance and scalability requirements are a critical factor for deciding between Platform as a Service and Infrastructure as a Service deployment models
2. In PAAS, you will be getting Root access to the operating system.

3. If your web application has a very high transactions volumes are good candidates for Platform as a Service

4. In an infrastructure as a service deployment, the cloud provider provides security patching, monitoring and fail over capabilities


Correct Answer : 1
Explanation: Managed cloud providers and some unmanaged cloud providers will either automatically, or with some manual control, provide installation and maintenance of
operating system patches for your workloads that are hosted in the cloud. While operating system patching will affect infrastructure as a service (IaaS), platform as a service
(PaaS) and software as a service (SaaS) clouds, in PaaS and SaaS offerings the middleware and applications are often under the provider's control. IaaS, however, is generally
there to host your applications, and, as we all know, some of our applications can be quite inflexible when it comes to their operating environment.





Question : You are an enterprise architect of ARINIKA Inc. You have after every days there will be a big spike of new data with multiple TB. And regulations says data
older than one year needs to be archived older than 3 years data needs to be removed. Which of the following is a best solution as well as low cost.



1. Estimate the peak volume over a 3 year period and set up a Hadoop system with commodity HW and storage to accommodate that volume.

2. Estimate the peak volume over a 3 year period and set up a Hadoop system with NAS to accommodate the expected volume

3. Use Cloud elasticity capabilities to handle the peak and valley data volume

4. Use SAN storage with compression to handle the peak and valley data volume

Correct Answer : 1
Explanation: Cheaper solution is using hadoop with commodity hardware. As we need to estimate approximate data volume for every 3 years and accordingly setup hadoop
cluster. Because, we can delete data after 3 years.





Question : SAN or NAS should not be used to set up HDFS

1. True
2. False

Correct Answer : 1
Explanation: Why use DAS when you can use Network Attached Storage (NAS) or SAN? For starters Hadoop is designed to be a "shared nothing" architecture where DAS will
suffice. Shared network storage like NAS or SAN could very well be overkill from a cost point of view if all you plan to store is petabytes of log and web 2.0 data in the Hadoop
cluster.
