Q.What are regions, availability domains, and fault domains?
Oracle Cloud Infrastructure is hosted in regions, each of which contain at least three availability domains. A region is simply a geographic area, such as “Germany” or “US West.”
An availability domain is an isolated, fault-tolerant set of resources consisting of at least one data center. Availability domains don't share infrastructure such as a building, power, or cooling. A failure in one availability domain is unlikely to impact the availability of other availability domains.
A fault domain is a grouping of hardware and infrastructure within an availability domain. Fault domains let you distribute your instances so they're not on the same physical hardware within a single availability domain, thereby introducing another layer of fault tolerance. Each availability domain contains three fault domains. A hardware failure or maintenance on Compute hardware that affects one fault domain doesn't affect instances in other fault domains.
Q. Which Resource is tied to an AD?
1.VCN
2.Route Table
3.Security List
4.Block Volume
5.Autonomous Data Warehouse.
Answer: 4.Block Volume.
Q.Where are IAM Resources (such as user and group) created?
1.Globally
2.In each region.
3.In each compartment.
4.In each Availability Domain.
Answer: 1.Globally.
Q.Can I attach block storage volumes to a bare metal server DB system?
No, you cannot attach block storage volumes to a bare metal server DB system. However, the Database Cloud Service on virtual machines services uses remote block volumes for databases that are completely managed by the platform.
Q.Does the 2-node RAC shape span across Availability Domains (AD)?
No, the 2-node RAC shape is a set on two servers within the same AD but different racks. Storage is shared across both instances. This set up protects against hardware failures on the instance. For higher availability, we recommend that your set up another 2-node RAC shape in a separate AD.
Q.Which is a customer’s responsibility on an Oracle Cloud Infrastructure database?
A.patching the database and OS
B.creating the first default database on the DBCS server
C.creating an ASM diskgroup for data file or temp file storage
D.installing the operating system (OS), Grid Infrastructure, and database software
Answer: A
