What type of storage capacity do block storage volumes provide?
A.
shared storage for applications on virtual machines (VMs) in Oracle Compute Cloud Service
B.
discrete storage disks that can be attached to virtual machines (VMs) in Oracle Compute Cloud Service
C.
scalable object storage in the cloud
D.
infinitely scalable storage for virtual machines (VMs) in Oracle Compute Cloud Service
E.
geo-replicated storage in the Oracle Public Cloud for any application running on-premises
Why B
Maybe C
It seems C.
according to this doc

Block storage is not object storage. I would go with B.
Correct answer: C
https://docs.oracle.com/en/cloud/iaas/storage-cloud/cssto/oracle-storage-cloud-service.html#GUID-6A4B4C1C-8025-4570-8D96-2780D5D98EF8
Block storage enables applications such as OLTP databases that have high IOPS (input/output operations per second) requirements to store and retrieve data efficiently, by bypassing the host operating system and interacting directly with virtual block devices. Chunks of data are stored in blocks, each with an address, but with no other metadata. Applications decide where data is stored, and they retrieve data by calling the appropriate block addresses directly. Block storage optimizes storage for IOPS and block-based access and provides POSIX-compliant file systems for Oracle Compute Cloud Service instances. It is limited in terms of scalability and does not support the definition of granular metadata for stored data.
Oracle Storage Cloud Service provides a low cost, reliable, secure, and scalable object-storage solution for storing unstructured data and accessing it anytime from anywhere. It is ideal for data backup, archival, file sharing, and for storing large amounts of unstructured data like logs, sensor-generated data, and VM images.
Sorry, for the same document: B.
Block storage is limited in terms of scalability.
Looks like B but I’m not sure.
Correct Answer : B
Any reference to support !!
Oracle gets very picky on its wording in their tests. I ruled out C because “object storage” to the Oracle Cloud is a different service, and is not “block storage” which is used by VM instances in the Computer Cloud.
A is not right, because block storage can’t be shared between two VMs.
D is not right, because there is a limit on the size and number of disks, so it is not “infinitely scalable.”
E – just no.
Correct answer B
Note that, within Oracle Compute Cloud Service, you can provide storage capacity for
your instances by attaching block storage volumes. But storage volumes can’t be
shared because a volume can be attached to only one Oracle Compute Cloud Service.
Besides, there’s a limit to the number and the size of the storage volumes that you can
attach to each Oracle Compute Cloud Service instance
