The given scenario mentions that a compute resource in a fabric group has 100 GB of memory, and the following memory reservations were created:

  • Business Group A: 60 GB
  • Business Group B: 60 GB

Memory reservations are a way to allocate memory resources to different business groups in a VMware vRealize Automation environment. These reservations ensure that each business group gets a guaranteed amount of memory, and the compute resource's available memory is partitioned accordingly.

Now, based on the given information, we can analyze each answer option:

A. Both business groups will compete for memory resources. This statement is not entirely correct. Both business groups will not compete for memory resources since they have been allocated reservations. However, the combined memory reservation of both business groups (60 GB + 60 GB = 120 GB) exceeds the available memory of the compute resource (100 GB), which can cause memory contention and potential performance issues.

B. Both business groups will be guaranteed 50 GB of memory This statement is also incorrect since the sum of memory reservations for both business groups (60 GB + 60 GB = 120 GB) exceeds the available memory of the compute resource (100 GB). Therefore, both business groups cannot be guaranteed 50 GB of memory.

C. Business group A will be guaranteed 60 GB of memory This statement is correct. Since the memory reservation for Business Group A (60 GB) does not exceed the available memory of the compute resource (100 GB), it can be guaranteed the full reservation of 60 GB. Business Group B, however, will not be able to guarantee its full memory reservation of 60 GB, and its memory allocation will depend on the availability of memory resources after allocating Business Group A's reservation.

D. The configuration will result in an error. This statement is not correct. There are no configuration errors in the given scenario.

Therefore, the correct answer is C. Business Group A will be guaranteed 60 GB of memory, and Business Group B will have to compete for the remaining memory resources after Business Group A's reservation is satisfied.
