Which two can be increased to scale up the compute shape of a Database as a Service (DBaaS) instance in Oracle Cloud?

A.
Add more memory to the DBaaS instance by using the Scale up button on the DBaaS Instance Overview page.

B.
Add more storage to the DBaaS instance by using the Scale up button on the DBaaS Instance Overview page.

C.
Add more network adaptors (NICs) to the storage network used by the DBaaS instance by using the Scale Up button on the DBaaS Instance Overview page.

D.
Add more network adaptors (NICs) to the public access network used by the DBaaS Instance by using the Scale Up button on the DBaaS Instance Overview
page.

E.
Add more CPUs to the DBaaS instance by using the Scale Up button on the DBaaS Instance.

Explanation:
Occasionally, the need to scale arises from some change made to the database or backup configuration after it was created. For example, if the decision to use the
In-Memory Database option was made after database creation, you might need to scale up the compute shape to one of the high-memory options, such as scaling
from “OC4 – 2 OCPU, 15 GB RAM” to “OC2M – 2 OCPU, 30 GB RAM”.
Note: To scale the compute shape for a database deployment:
1) View the overview page for the database deployment:
a) Open the Oracle Database Cloud Service console.
b) Click the name of the deployment you want to scale.
The Oracle Database Cloud Service Overview page is displayed.

1. 2. Choose the scaling command.
The Scale Up/Down Service overlay is displayed. Note that the overlay includes information about the current compute shape.
2. Select a new compute shape.
3. Click Yes, Scale Up/Down Service to scale the database deployment.
The scaling operation begins. The database deployment is in Maintenance status and unavailable while the scaling operation is in progress.
