NEW QUESTION # 44
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)
Answer: C,D
Explanation:
Enabling auto scaling on an existing Autonomous Database can be done without unnecessary complexity:
Correct Answer (A): “Click Scale Up/Down and select the Auto Scaling checkbox” is the simplest GUI method. In the OCI Console, navigate to the database, select “Scale Up/Down,” and enable the auto scaling option, allowing up to 3x the base OCPUs dynamically.
Correct Answer (C): “Use a REST call to enable Auto Scaling” leverages the OCI REST API to update the database configuration with the isAutoScalingEnabled parameter set to true. This is ideal for programmatic control.
Incorrect Options:
B: Shutting down the instance is unnecessary; auto scaling can be enabled while the database is running.
D: Multiple REST calls, including shutdown and restart, overcomplicate the process when a single API call suffices.
These methods ensure minimal disruption and efficient resource management.
NEW QUESTION # 45
How can you keep Autonomous Database tables in sync with an on-premises data source?
Answer: C
Explanation:
Keeping Autonomous Database tables synchronized with an on-premises data source involves loading and updating data from external locations. The Cloud Locations card on the Data Load page is the correct method:
Correct Answer (B): The Cloud Locations card allows users to connect to Oracle Cloud Infrastructure (OCI) Object Storage buckets and load data into Autonomous Database tables. By regularly updating the data in Object Storage from the on-premises source (e.g., via scripts or tools), you can maintain synchronization using this feature. It supports automated data loading workflows when paired with appropriate processes.
Incorrect Options:
A: Oracle REST Data Services (ORDS) is used for building RESTful web services, not for direct data synchronization from on-premises sources to Autonomous Database tables.
C: The Link Data option enables linking to external database tables (e.g., via database links), but it doesn’t inherently synchronize data; it provides access rather than replication.
D: There is no “FEED DATA” option on the Data Load page in Autonomous Database; this appears to be a fabricated choice.
This method leverages OCI Object Storage as an intermediary, making it a practical solution for ongoing synchronization.
NEW QUESTION # 46
Which two statements are true regarding active transactions when scaling OCPUs in an Autonomous Database? (Choose two.)
Answer: A,C
Explanation:
Scaling OCPUs in Autonomous Database is designed to be seamless. The two true statements are:
Scaling can happen while there are active transactions in the database (B): ADB supports online scaling, meaning you can increase or decrease OCPUs (e.g., from 2 to 4) via the OCI console or CLI (e.g., oci db autonomous-database update --cpu-core-count 4) without stopping the database. Active transactions (e.g., INSERT INTO orders VALUES (...)) continue running during this process. Oracle’s architecture ensures the database remains available, adjusting resources in the background. For example, a web app processing orders won’t notice the scaling operation starting at 10:00 AM.
Active transactions continue running unaffected (C): During scaling, existing transactions are not interrupted, terminated, or paused. They complete normally, with Oracle managing resource allocation transparently (e.g., shifting CPU usage without killing sessions). For instance, a long-running UPDATE statement started before scaling finishes successfully, leveraging the database’s high-availability design. The status shows “SCALING IN PROGRESS,” but users experience no downtime.
The incorrect options are:
Active transactions are terminated and rolled back (A): False. Scaling is non-disruptive; transactions aren’t killed or rolled back, preserving data integrity and user experience. Termination only occurs during explicit stops or failures, not scaling.
Active transactions are paused (D): False. There’s no pausing mechanism during scaling; transactions run continuously, as pausing would disrupt OLTP or analytical workloads, countering ADB’s autonomous promise.
This online scaling capability is a key benefit, ensuring uninterrupted service.
NEW QUESTION # 47
Your company has a .NET application and wants to deploy it on Autonomous Database (ADB). What software is used to connect to ADB from the .NET application?
Answer: D
Explanation:
Connecting a .NET application to Autonomous Database (ADB) requires a specific client library compatible with Oracle’s database connectivity standards. The correct software is:
Oracle Data Access Components for Windows (D): Oracle Data Access Components (ODAC) for Windows is the recommended software for .NET applications to connect to ADB. ODAC includes the Oracle Data Provider for .NET (ODP.NET), which supports ADO.NET interfaces for database access. It enables .NET developers to use familiar APIs (e.g., OracleConnection, OracleCommand) to interact with ADB over Oracle Net Services, leveraging the secure TLS connection required by ADB (via the client wallet). For example, a .NET app might use ODAC to execute SELECT * FROM customers against an ADB instance, authenticating with a wallet downloaded from the OCI console. ODAC supports both managed and unmanaged modes: the managed ODP.NET is lightweight and assembly-based, while the unmanaged version integrates with Oracle Client libraries. To set it up, developers install ODAC (e.g., via NuGet or Oracle’s download site), configure the wallet (e.g., tnsnames.ora), and write code like:
csharp
CollapseWrapCopy
using Oracle.ManagedDataAccess.Client;
string connString = "User Id=USER1;Password=pwd;Data Source=adb_high"; using (OracleConnection conn = new OracleConnection(connString)) { conn.Open();
// Query execution here
}
This ensures seamless integration with ADB’s managed environment, supporting features like connection pooling and high performance.
The incorrect options are:
SQL*Plus (A): SQL*Plus is a command-line tool for SQL execution and administration, not a programmatic library for .NET applications. It’s unsuitable for embedding in a .NET app, as it lacks API integration and is meant for manual use (e.g., running scripts like SELECT * FROM table;).
You cannot use .NET with ADB (B): This is false. .NET is fully supported via ODAC, allowing applications (e.g., ASP.NET web apps or Windows services) to connect to ADB just like any Oracle database, provided the wallet and credentials are configured.
Java (C): Java uses JDBC (e.g., Oracle JDBC Driver) for database connectivity, not .NET. While JDBC works with ADB for Java apps, it’s irrelevant for a .NET environment, where ODAC is the standard.
ODAC’s robust support for .NET makes it the definitive choice, bridging Microsoft’s ecosystem with Oracle’s cloud database.
NEW QUESTION # 48
What are two advantages of using Data Pump to migrate your Oracle databases to Autonomous Database? (Choose two.)
Answer: A,D
Explanation:
Oracle Data Pump is a powerful tool for migrating databases to Autonomous Database (ADB). The two correct advantages are:
Data Pump can exclude migration of objects like indexes and materialized views that are not needed by Autonomous Database (C): True. Data Pump’s EXCLUDE parameter allows skipping objects like indexes and materialized views during export (e.g., expdp ... EXCLUDE=INDEX,MATERIALIZED_VIEW). In ADB, these objects are often redundant because the database automatically creates and manages them based on workload (e.g., auto-indexing). For example, exporting a schema with EXCLUDE=INDEX from an on-premises database reduces migration overhead, as ADB recreates necessary indexes post-import, optimizing for its managed environment. This flexibility minimizes unnecessary data transfer and speeds up the process.
Data Pump is platform-independent - it can migrate Oracle databases running on any platform (D): True. Data Pump uses a platform-agnostic dump file format (.dmp), enabling migration from any Oracle Database (e.g., on Linux, Windows, or Solaris) to ADB in the cloud. For instance, you could export from an Oracle 12c database on AIX, upload the dump to OCI Object Storage, and import it into ADB using DBMS_CLOUD.COPY_DATA, regardless of endianness or OS differences (handled by Data Pump’s conversion). This universality makes it ideal for heterogeneous migrations.
The incorrect options are:
Data Pump is faster to migrate database than using RMAN (A): False. Speed depends on context—RMAN (Recovery Manager) is faster for physical migrations (e.g., restoring backups) of entire databases, especially large ones, due to block-level copying. Data Pump, a logical migration tool, extracts and loads data row-by-row, which can be slower for massive datasets but offers more control (e.g., schema selection). No universal speed advantage exists; it’s workload-specific.
Data Pump creates the tablespaces used by your Autonomous Database (B): False. In ADB, tablespaces are fully managed by Oracle (e.g., DATA tablespace), and Data Pump doesn’t create them. It imports data into existing, pre-allocated storage, ignoring source tablespace definitions. E.g., a source tablespace USERS is mapped to ADB’s default storage, not recreated.
These advantages make Data Pump a versatile, tailored migration solution for ADB.
