Which resource type would you create in Full Stack Disaster Recovery (FSDR) to represent a consistency grouping of Oracle Cloud Infrastructure (OCI) resources for disaster recovery purposes?
In Full Stack Disaster Recovery (FSDR), a Disaster Recovery Protection Group is the resource type used to represent a consistency grouping of OCI resources for disaster recovery purposes.
=================
How does the Copy to another region feature in Oracle Cloud Infrastructure (OCI) aid in achieving smooth transitions during Block Volume migration?
The correct choice is that the Copy to another region feature in OCI aids in achieving smooth transitions during Block Volume migration by replicating Block Volume backups to a target region. This enables a seamless data migration process without the need for manual backup and restore operations.
=================
Your company wants to expand its cloud infrastructure footprint by adopting Oracle Cloud VMware Solution (OCVS). The OCVS Software Defined Data Center (SDDC) platform will be dedicated to hosting business-critical workloads and should avoid single points of failure within its architecture. Which two would be considered while setting up the solution?
OCI Fault Domains and vSAN Fault Domains are critical considerations to avoid single points of failure and ensure high availability for business-critical workloads hosted on the OCVS SDDC platform.
=================
One of your customers is planning to consolidate many of their single-instance databases into a suitable database solution in OCI. Their goal is to optimize resource utilization and reduce maintenance and management overhead. What would you suggest as a migration architect?
Grouping and migrating related databases into OCI Base Database service on multitenant architecture allows for efficient resource utilization and reduced management overhead.
=================
A cluster of physical servers running in an on-premises data center is configured with a total of 100 GB physical memory. The total virtual memory allocated across all the VMs running on this cluster is 200 GB. Which term describes the virtual-to-physical memory allocation ratio for this cluster?
Oversubscription occurs when the total virtual memory allocated across all VMs exceeds the total physical memory available in the cluster.
