The volume of transactions of your rental business is increasing. You anticipate a rise in workload during the upcoming holiday sales event. You want to ensure that the business is not impacted during the event due to an overloaded database system. Based on your database administrator's suggestion, you intend to scale up your Virtual Machine DB System during the event period to address the resource demand.
Which of the following TWO statements are true about scaling the Virtual Machine DB System? (Choose two.)

Answer options

• A. You can only scale up a database system, but cannot scale it down.
• B. You can perform scaling operations only after the database system is down.
• C. You can change the shape of a Virtual Machine DB System to change the number of OCPU cores.
• D. You can scale up storage in a Virtual Machine DB System without any downtime.
• E. You can only scale up OCPUs, but not storage.

Correct answer: C, D

Explanation

Option C is correct because you can change the shape of a Virtual Machine DB System to adjust the number of OCPU cores. Option D is also correct, as you can scale up storage without downtime. Options A and B are incorrect as scaling down is possible, and scaling can occur while the database system is online. Option E is wrong because both OCPUs and storage can be scaled up.
