NEW QUESTION # 115
You have been tasked with analyzing a year’s worth of sales data stored in an Autonomous Data Warehouse instance. Which tool would you use to automate data exploration and create pivot tables?
Answer: B
Explanation:
Full Detailed In-Depth Explanation:
A: False. APEX is for app development, not data exploration.
B: False. SQL Developer Web is for SQL queries, not pivot tables.
C: True. Business Models in ADW automates data exploration and generates pivot tables.
D: False. Data Load is for importing data, not analysis.
NEW QUESTION # 116
Given the steps:
Create Oracle Machine Learning User
Create Projects
Create Workspaces
Create Notebooks
Run SQL Scripts
Which two steps are out of order when working with Oracle Machine Learning?
Answer: B,C
Explanation:
Full Detailed In-Depth Explanation:
The correct sequence for Oracle Machine Learning (OML) is:
Create Oracle Machine Learning User: First step to enable OML access.
Create Workspaces: Containers for organizing projects.
Create Projects: Groups for related notebooks within a workspace.
Create Notebooks: Environments for coding and analysis.
Run SQL Scripts: Executed within notebooks.
In the given list, Create Projects (2) comes before Create Workspaces (3), which is reversed. Workspaces must exist before projects. Thus, C and D are out of order.
NEW QUESTION # 117
Which stage of the indexing pipeline divides text into tokens?
Answer: D
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 # 118
Which command can you use to create an Autonomous Database?
Answer: B
Explanation:
Creating an Autonomous Database (ADB) via OCI’s REST API involves a specific endpoint. The correct command is:
POST /20160918/autonomousDatabases (D): This is the official REST API endpoint to create an ADB instance. The POST request to /20160918/autonomousDatabases (versioned at API 20160918) submits a JSON payload defining the database (e.g., compartment, name, workload type). Example:
curl -X POST "https://database.us-ashburn-1.oraclecloud.com/20160918/autonomousDatabases" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{
"compartmentId": "ocid1.compartment.oc1..example",
"dbName": "MYADB",
"cpuCoreCount": 1,
"dataStorageSizeInTBs": 1,
"dbWorkload": "OLTP",
"adminPassword": "Secure#123"
}'
This creates an ATP instance named MYADB with 1 OCPU and 1 TB storage. The response includes an OCID (e.g., ocid1.autonomousdatabase.oc1..example), and provisioning starts asynchronously, visible in the OCI console as “PROVISIONING.” The endpoint’s plural form (autonomousDatabases) reflects the resource collection, consistent with OCI API conventions.
The incorrect options are:
POST /20160918/createADB (A): No such endpoint exists. OCI APIs use resource-based paths (e.g., /autonomousDatabases), not action-specific ones like createADB.
POST /20160918/createautonomousDatabases (B): Incorrect syntax—APIs don’t prepend “create” to resource paths, and “autonomousDatabases” is lowercase here, matching the real endpoint.
POST /20160918/createDatabases (C): Too generic; it doesn’t specify “autonomous” databases, and no such endpoint exists for ADB creation.
This REST command is a programmatic alternative to console-based provisioning, ideal for automation.
NEW QUESTION # 119
Which predefined service connection should you use when running lots of high concurrent queries in an Autonomous Database?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Service connections in Autonomous Database:
A . DBNAME_LOW: Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.
B . DBNAME_MEDIUM: Balanced concurrency and performance.
C . DBNAME_HIGH: Prioritizes individual query performance, not concurrency.
D . DBNAME_CONCURRENT: Not a valid service name.
