NEW QUESTION # 147
Which stage of the indexing pipeline divides text into tokens?
Answer: C
Explanation:
The indexing pipeline in Oracle Text processes text for search:
Correct Answer (D): “Lexer” divides text into tokens (words, symbols) based on language rules and settings (e.g., whitespace, punctuation). It’s the stage responsible for tokenization in Oracle’s text indexing process.
Incorrect Options:
A: Sectioner identifies document sections (e.g., headers), not tokens.
B: Tokenizer is a generic term, but in Oracle Text, “Lexer” is the specific component.
C: Filter preprocesses text (e.g., removing stopwords), post-tokenization.
This step enables efficient text search capabilities.
NEW QUESTION # 148
Which statement is NOT correct when the Autonomous Database is stopped?
Answer: C
Explanation:
When an Autonomous Database is stopped, its operational state changes significantly:
Correct Answer (C): “User with DWROLE can still access the database” is not correct. When the database is stopped, all access is disabled, including for users with roles like DWROLE (a predefined role for Data Warehouse tasks). The database is offline, and no connections or operations are possible until it is restarted.
True Statements:
A: Tools (e.g., SQL Developer, JDBC clients) cannot connect to a stopped instance because the database services are unavailable.
B: In-flight transactions and queries are terminated upon stopping, with any uncommitted changes rolled back to maintain data consistency.
D: CPU billing ceases when the database is stopped, though storage billing continues, reflecting Oracle’s pay-per-use model for compute resources.
This behavior ensures resource conservation and cost control while maintaining data integrity.
NEW QUESTION # 149
While provisioning a dedicated Autonomous Container Database, which backup retention period CANNOT be implemented?
Answer: D
Explanation:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle provides specific options for backup retention periods to balance data recovery needs with storage costs. According to the official Oracle documentation, the available backup retention periods for a dedicated ACD are:
7 days: This is the default retention period for a newly provisioned ACD.
15 days: An option for extended retention beyond the default.
60 days: The maximum supported retention period for ACDs, offering the longest recovery window.
The option of 120 days is not supported as a backup retention period for an Autonomous Container Database. This limitation is due to the design of the Autonomous Database service, which caps retention at 60 days to optimize storage and performance on dedicated Exadata infrastructure. Attempting to set a retention period beyond 60 days is not an available choice during provisioning. Users must select a retention period that meets their recovery point objectives (RPO) within these constraints, noting that longer retention increases storage usage and associated costs.
NEW QUESTION # 150
What REST verb is used to create an Autonomous Database service using REST APIs?
Answer: A
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 # 151
Which statement is FALSE about Autonomous Database maintenance on Dedicated Infrastructure?
Answer: C
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.
