質問 # 43
While Autonomous Transaction Processing and Autonomous Data Warehouse use the same Oracle database, which statement is true about the workloads?
- A. Autonomous Transaction Processing memory usage optimizes workloads for parallel joins and aggregations.
- B. Data that is bulk loaded, by default, uses the row format in Autonomous Transaction Processing where Autonomous Data Warehouse data format is columnar.
- C. Autonomous Data Warehouse workloads are optimized for mixed workloads.
- D. Autonomous Transaction Processing workloads are optimized for data warehouse, data mart, and data lake.
正解：B
解説：
- Both ADW and ATP share the Autonomous Database platform of Oracle Database on Exadata Cloud infrastructure.
The difference is how the services have been optimized within the database. When you start loading data into the autonomous database, we store the data in the appropriate format for the workload.
* If it is ADW, then we store data in columnar format because that's the best format for analytics processing.
* If it is ATP, then we store the data in row format because that's the best format for fast single row lookups.
- Oracle Autonomous Database is offered in two workload-optimized flavors
* Autonomous Data Warehouse (ADW), which has been optimized for analytic workloads
* Autonomous Transaction Processing (ATP). ATP is optimized for transaction processing or mixed workload

質問 # 50
Which statement is false about Autonomous Database Oracle Client Credentials (Wallets)?
- A. The Oracle Client Credential file is downloaded as a ZIP file.
- B. The Wallet for the Autonomous Database is the same as the Transparent Data Encryption (TDE) wallet.
- C. In addition to the Oracle Client Credential Wallet, a user must have a username and password in order to connect to the Autonomous Database.
- D. You MUST have an Oracle Client Credential Wallet in order to connect to the Autonomous Database.
正解：B
解説：
When you download the client credentials from the Download Wallet dialog, you must enter a wallet password in the password field and confirm the password in the confirm password field. The password must be at least eight characters long and must include at least one letter and one numeric character or one special character. This password protects the download client credentials wallet. This wallet is not the same as the transparent data encryption wallet for the database. Therefore, a different password is used to protect the client credentials wallet.
