Cloud Infrastructure? (Choose two.)
  1. A
    Load text files into ATP using SQL Developer.
  2. B
    Use RMAN duplicate.
  3. C
    Use Oracle Data Pump.
  4. D
    Transfer the physical database files and re-create the database.
  5. E
    Use database backup and restore.

Correct Answer:
CD

Question #17
Which statement is NOT true about the Oracle Cloud Infrastructure Object Storage service?
  1. A
    Object storage resources can be shared across tenancies.
  2. B
    Immutable option for data stored in the Object Storage can be set via retention rules.
  3. C
    Object versioning is enabled at namespace level.
  4. D
    Object lifecycle rules can be used to either archive or delete objects.

Correct Answer:
B

Question #18
You are about to upload a large log file (5 TIB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload.
Which two statements are true about multipart upload? (Choose two.)
  1. A
    The maximum size for an uploaded object is 10 TiB.
  2. B
    You do not have to commit the upload after you have uploaded all the object parts.
  3. C
    Individual object parts can be as small as 10 MiB or as large as 50 GiB.
  4. D
    While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000.

Correct Answer:
AC

Question #19
You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud Infrastructure. As the game becomes popular, you identify network throughput as a bottleneck on your instance when uploading user data.
Though you want to resolve the issue, you want to observe the demand for a week before adding new application instances.
Which action is the most efficient way to resolve this issue?
  1. A
    Add a secondary virtual network interface card (VNIC).
  2. B
    Change shape of the instance to a higher network bandwidth instance.
  3. C
    Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.
  4. D
    Change the performance tier of attached block volume to High Performance.

Correct Answer:
B

Question #20
You have an AI/ML application running on Oracle Cloud Infrastructure. You identified that the application needs GPU and at least 20Gbps Network throughput.
The application is currently using a VM.Standard2.1 compute without any block storage attached to it.
Which two options allow you to get your required performance for your application? (Choose two.)
  1. A
    Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.
  2. B
    Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved, but no block volume attached.
  3. C
    Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.GPU3.4 shape using the boot volume preserved and use the NVMe devices to host your application.
  4. D
    Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.HPC2.36 shape using the boot volume preserved and use the NVMe devices to host your application.
  5. E
    Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved and attach a new block volume to host your application.

Correct Answer:
DE
