質問 # 39
Which two target database environments provide both high availability (HA) and disaster re-covery (DR) options in the cloud? (Choose all correct answers)
- A. Compute VM
- B. Streaming Service
- C. Autonomous Database
- D. Exadata Cloud Service
正解：C、D
解説：
Exadata Cloud Service and Autonomous Database are two target database environments that provide both high availability (HA) and disaster recovery (DR) options in the cloud. Exadata Cloud Service is a fully managed Oracle Database service that runs on Exadata infrastructure in the cloud. It offers high performance, scalability, availability, security, and reliability for all types of database workloads. It also supports various HA and DR options, such as Oracle Real Application Clusters (RAC), Oracle Data Guard, Oracle Active Data Guard, Oracle GoldenGate, and Oracle Zero Data Loss Recovery Appliance Cloud Service. Autonomous Database is a self-driving, self-securing, and self-repairing cloud database service that automates provisioning, configuring, securing, tuning, scaling, patching, backing up, and repairing of databases without human intervention. It also provides built-in HA and DR features based on Oracle Maximum Availability Architecture (MAA), such as transparent application continuity, automatic failover to standby databases or regions, automatic backups to object storage, point-in-time recovery using restore points or backups.
質問 # 40
The DBA has determined that number of OCPU assigned to an Autonomous Database does not provide sufficient performance. Which option does the DBA have in this case?
- A. Plan for a one-hour downtime and increase the number of OCPU while database is of-fline.
- B. Open the database in OCI Console and increase the number of OCPU. No downtime required.
- C. No downtime is required as number of OCPU can be increased from OCI console, but users have to be informed that they must not use any application for at least one hour.
- D. Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour.
正解：B
解説：
This option is the correct way to increase the number of OCPU assigned to an Autonomous Database. According to the Oracle documentation2, "You can scale your Autonomous Database on demand by adding CPU cores or storage. You can also enable auto scaling to allow your Autonomous Database to automatically use up to three times more CPU and IO resources than its allocated CPU core count." The scaling operation does not require any downtime or affect the availability of the database.

- B. Only bare metal DB systems can increase block storage at any time without impacting the system.
- C. If a VM DB system has different requirements for block storage, increase or decrease the storage at any time without impacting the system.
- D. If d VM DB system requires more block storage, increase the storage at any time without impacting the system.
正解：A
質問 # 42
What three typical data types/models are covered by Oracle's Converged Database? (Choose all correct answers)
- A. Events
- B. Spatial
- C. Images
- D. Graph
- E. Relational
- F. Terraform
正解：B、D、E
解説：
Graph, relational, and spatial are three typical data types/models that are covered by Oracle's Converged Database. A converged database is a multi-model, multitenant, multi-workload database that supports the data model and access method each development team wants, without unneeded functionality getting in the way. A graph data model represents data as nodes and edges, and enables complex queries based on relationships and patterns. A relational data model organizes data into tables with rows and columns, and supports SQL queries and transactions. A spatial data model stores and manipulates geometric and geographic data, such as points, lines, polygons, and raster images.

質問 # 46
Oracle Cloud and Microsoft Azure have an interconnect for workloads across cloud. Which two are also benefits this partnership and interconnect provide? (Choose all correct answers)
- A. Low Latency
- B. Upgrade compliance
- C. Unified identity and access management
- D. Connection to other multicloud environments

A customer wants to use Oracle Cloud Infrastructure (OCI) for storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. Archive Storage
- B. File Storage
- C. Object Storage (standard)
- D. Block Volume
正解：C
解説：
Object Storage (standard) is the OCI storage service that can be used to store application backups which can be stored for months, but retrieved immediately based on business needs. According to the Oracle documentation1, "Object Storage is a highly scalable, durable, and available cloud-based storage service that provides a cost-effective way to store and manage large amounts of unstructured data such as images, videos, and log files. Object Storage supports standard HTTP operations such as GET, PUT, and DELETE, as well as advanced features such as encryption, data replication, lifecycle policies, and pre-authenticated requests." Object Storage (standard) offers high performance and low latency for frequent data access.
