NEW QUESTION # 140
What are three characteristics of Data Lake data captured in Object Storage? (Choose three.)
Answer: A,D,E
Explanation:
Data Lakes in OCI Object Storage store raw data for analysis. The three correct characteristics are:
Schema on read (C): Data Lakes store data in its raw, native format (e.g., JSON, CSV, Parquet) without a predefined schema. The schema is applied when data is read or processed, not when written, offering flexibility. For example, a Parquet file with sales data might be queried with SQL only when analyzed, not structured upfront like in a database.
Multiple subject areas (D): Data Lakes aggregate data from diverse sources—sales, HR, IoT—spanning multiple subject areas. This enables cross-domain analysis, like combining customer data with weather data for insights, all stored in a single OCI bucket.
Mixed data types (E): Data Lakes support varied formats: structured (e.g., CSV tables), semi-structured (e.g., JSON documents), and unstructured (e.g., videos). For instance, a bucket might hold CSV logs, JSON events, and image files, all accessible for processing.
The incorrect options are:
High concurrency (A): Data Lakes in Object Storage are not designed for high-concurrency transactional access (e.g., thousands of simultaneous updates). They’re optimized for batch processing or analytics, unlike ATP’s concurrency focus.
High transaction performance (B): Transactional performance (e.g., fast commits) is a database strength, not a Data Lake’s. Object Storage prioritizes scalability and durability over transactional speed, making it unsuitable for OLTP workloads.
These traits make Data Lakes ideal for big data analytics, not real-time transactions.
NEW QUESTION # 141
Which statement is true when you provision an Autonomous Database using the cloning method?
Answer: B
Explanation:
Cloning in Autonomous Database creates a new instance from an existing source:
Correct Answer (A): “A clone database source can be a running database instance” is true. You can clone from a live, running Autonomous Database instance (full clone), capturing its current state, including data and configuration, without needing to stop it.
Incorrect Options:
B: There are multiple cloning types: full clone (from a running instance) and refreshable clone (a read-only copy that syncs with the source), plus cloning from backups.
C: Cloning from a backup requires the backup to be at least 2 hours old for consistency, not less, making this false.
D: Security zone rules prevent cloning a database from a security zone to a non-security zone due to compliance restrictions.
This flexibility supports rapid provisioning from active databases.
NEW QUESTION # 142
What is the correct way to list all files in the default data pump directory?
Answer: D
Explanation:
In Oracle Autonomous Database, the DBMS_CLOUD package provides tools to interact with cloud storage and directory operations, including listing files in the default Data Pump directory (DATA_PUMP_DIR).
Correct Answer (A): The statement SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR'); is the officially supported method to list files in the DATA_PUMP_DIR. This function returns a result set with details about files in the specified directory, tailored for the managed environment of Autonomous Database.
Incorrect Options:
B: This is false; you can list files in DATA_PUMP_DIR using DBMS_CLOUD.LIST_FILES, as it is designed for this purpose in ADW.
C: The UTL_FILE package is not recommended for Autonomous Database due to its limitations in a cloud-managed environment. DBMS_CLOUD is the preferred utility for such operations. Additionally, the syntax UTL_FILE.LIST is incorrect; the proper procedure would be UTL_FILE.FGETATTR or similar, but it’s still not applicable here.
D: Autonomous Database is a fully managed service, and users do not have direct command-line access to the underlying server. Commands like ls -al are unavailable as there’s no shell access.
This approach ensures secure and efficient file management within the constraints of a serverless cloud database.
NEW QUESTION # 143
What REST verb is used to create an Autonomous Database service using REST APIs?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
REST APIs use HTTP verbs:
A: True. POST creates new resources, such as an Autonomous Database instance.
B: False. GET retrieves data, not creates.
C: False. PUT updates existing resources.
D: False. INSERT is not a REST verb; it’s SQL-specific.
NEW QUESTION # 144
Which statement is FALSE about Autonomous Database maintenance on Dedicated Infrastructure?
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
Maintenance on dedicated infrastructure:
A: True. You can adjust maintenance windows for container databases.
B: False. Exadata Infrastructure maintenance (e.g., OS, grid patching) is separate from container database patching, which occurs independently.
C: True. Oracle reschedules missed maintenance to the next quarter.
D: True. Infrastructure maintenance occurs quarterly.
