Exam 1z0-1072-20 topic 1 question 20 discussion

Actual exam question from Oracle's 1z0-1072-20
Question #: 20
Topic #: 1
[All 1z0-1072-20 Questions]

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.)

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

I would go with A and E. All GPU shapes provide at least 25gbs network throughput. The original instance is bandwidth limited, no mention of disk write speed. So I would go without block storage or with block storage since it's the cheaper option.

A, E because B,D has no GPU, C has no NVMe.

Answer is DE. https://docs.oracle.com/en-us/iaas/Content/Compute/References/computeshapes.htm Shape models whose names that with BM use NVMe disks

BM.HPC2.36 is not GPU so option D is not a valid answer. Option B model is VM.Standard2.2 and is not GPU either. A may not solve the disk problem in "...but no block volume attached." C is false because VM.GPU3.4 has block storage, no NVMe. E is correct since its GPU and adds a block volume. So answer is E & A

I think it's C&D. Because BM.GPU2.2 are no longer supported. It entered it's end of orderability on December 2020. https://docs.oracle.com/en-us/iaas/Content/Compute/References/computeshapes.htm#previous-generation-shapes__previous-generation-bm

its A and E. they need to increase the compute power. Forget the NVMe as 2 is already enough

A&D because: - B can't serve the purpose, it is VM.Standard2.2 and we need something that has strong CPU; - C will serve the purpose, but improving the storage was not a point. We had to improve CPU and Network in this exercise and not the storage. Adding NVME will increase the cost; - E serves the purpose, but again we do not need any additional storage here. Both BM.HPC2.36 and BM.GPU2.2 have 25 Gbps, https://docs.oracle.com/en-us/iaas/Content/Compute/References/computeshapes.htm#baremetalshapes__bm-hpc -

D&E: you need the 20Gbps and thus: BM. Next to that, you would need a lot of GPU power, thus next to the BM with GPU, you also have the High Performance Computing, which has quite some GPU power ;)

One addition why E: Block volume - thus nvme...

Answer is A & E: the only shapes that have GPU are the ones with GPU in their names C is not because the only shapes with NVMe are the 'Dense' ones in their name, plus BM.GPU4.8 and BM.HPC2.36 (but no GPU) --> So the only GPU with NVMe is BM.GPU4.8

It can contain NVMe discs as mentioned in the document https://docs.cloud.oracle.com/en-us/iaas/Content/Compute/References/computeshapes.htm

It needs to be AE. Although C is GPU as-well, it's false statement, as it does not contain NVMe discs, local disc can be block storage only.
