NEW QUESTION 14
Which two Oracle Cloud Infrastructure database services allow you to dynamically scale both CPU and storage? (Choose two.)
- A. bare metal DB system
- B. Autonomous Transaction Processing (ATP)
- C. Autonomous Data Warehouse (ADW)
- D. virtual machine DB system
Answer: A,D
NEW QUESTION 15
While Autonomous Transaction Processing and Autonomous Data Warehouse use the same Oracle database, which statement is true about the workloads?
- A. Data that is bulk loaded, by default, uses the row format in Autonomous Transaction Processing where Autonomous Data Warehouse data format is columnar.
- B. Autonomous Transaction Processing memory usage optimizes workloads for parallel joins and aggregations.
- 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.
Answer: A
Explanation:
- 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

NEW QUESTION 20
Which statement is false about Autonomous Database Oracle Client Credentials (Wallets)?
- A. The Oracle Client Credential file is downloaded as a ZIP file.
- B. In addition to the Oracle Client Credential Wallet, a user must have a username and password in order to connect to the Autonomous Database.
- C. You MUST have an Oracle Client Credential Wallet in order to connect to the Autonomous Database.
- D. The Wallet for the Autonomous Database is the same as the Transparent Data Encryption (TDE) wallet.
Answer: D
Explanation:
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.

NEW QUESTION 24
Which statement is true regarding database client credentials file required to connect to your Autonomous Database?
- A. Store credential files in a secure location and share the files only with authorized users to prevent unauthorized access to the database.
- B. The Transparent Data Encryption (TDE) wallet can be used for your client credentials to connect to your database.
- C. Place the credential files on a share drive that all users can use to connect to the database.
- D. When you share the credential files with authorized users, mail the wallet password and the file in the same email.
Answer: A
Explanation:
Connection to Autonomous DB uses certificate authentication and Secure Sockets Layer (SSL). This ensures that there is no unauthorized access to Autonomous DB and that communications between the client and server are fully encrypted and cannot be intercepted or altered.
Certification authentication uses an encrypted key stored in a wallet on both the client (where the application is running) and the server (where your database service on the Autonomous DB is running). The key on the client must match the key on the server to make a connection There's credentials zip file available for download once ADB is created, the zip file contains a collection of files, that needed to connect to your Autonomous DB. All communications between the client and the server are encrypted Wallet files, along with the Database user ID and password provide access to data in your Autonomous Transaction Processing database. Store wallet files in a secure location. Share wallet files only with authorized users. If wallet files are transmitted in a way that might be accessed by unauthorized users (for example, over public email), transmit the wallet password separately and securely.
For better security, Oracle recommends using restricted permissions on wallet files. This means setting the file permissions to 600 on Linux/Unix.
Similar restrictions can be achieved on Windows by letting the file owner have Read and Write permissions while all other users have no permissions.
