OCI exam question (1z0-1072)

Andy68

Hi

I am studying for the above exam. I'm focused on the Oracle Database Cloud Service topic currently.

I am using exam study guides, i.e., typical questions that come up on the exam.

One question that comes up a few times on the exam paper I have is:

What scaling option does DBCS on Bare Metal Shape offer?

A. network bandwidth

B. CPU

C. Storage

D. Memory

Answer: C

I thought the answer was actually B, CPU. I am using the following reference: https://docs.cloud.oracle.com/iaas/Content/Database/Concepts/overview.htm

It mentions the two shape options for Bare Metal and storage considerations but nothing specifically about scaling options.

It then moves on to VM DB Systems, stating:

Virtual machine DB systems also differ from bare metal DB systems in the following ways:

• A virtual machine DB system database uses Oracle Cloud Infrastructure block storage instead of local storage. You specify a storage size when you launch the DB system, and you can scale up the storage as needed at any time.
• The number of CPU cores on an existing virtual machine DB system cannot be changed.

These two bullet-points suggest to me that the number of CPU cores cannot be changed on a VM DB system, but can on a Bare Metal DB system, and storage cannot be changed on a Bare Metal system but can on a VM DB system.

Can someone put me out of my misery and confirm either way?

Thanks

Andy

Community Administrators - is there a better option available where I can get a definitive answer to this question?

Thanks

Your question is in the right place, at least since it is about Certification, but there may be no people that can actually help you.

By mentioning   the question will appear on that space, so you may also get answers from people that follow that space

Hi Andy,

The answer is "CPU"

Please review: https://docs.cloud.oracle.com/en-us/iaas/Content/Database/Tasks/managingDBsystem.htm

Topic: To scale the CPU cores for a bare metal DB system

If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system.

Thanks,
