최신 Oracle Database 23ai 1Z0-184-25 무료샘플문제 (Q54-Q59):
질문 # 54
A database administrator wants to change the VECTOR_MEMORY_SIZE parameter for a pluggable database (PDB) in Oracle Database 23ai. Which SQL command is correct?
- A. ALTER SYSTEM SET VECTOR_MEMORY_SIZE=1G SCOPE=SGA
- B. ALTER SYSTEM RESET VECTOR_MEMORY_SIZE
- C. ALTER SYSTEM SET VECTOR_MEMORY_SIZE=1G SCOPE=BOTH
- D. ALTER DATABASE SET VECTOR_MEMORY_SIZE=1G SCOPE=VECTOR
정답：C
설명：
VECTOR_MEMORY_SIZE in Oracle 23ai controls memory allocation for vector operations (e.g., indexing, search) in the SGA. For a PDB, ALTER SYSTEM adjusts parameters, andSCOPE=BOTH (A) applies the change immediately and persists it across restarts (modifying the SPFILE). Syntax: ALTER SYSTEM SET VECTOR_MEMORY_SIZE=1G SCOPE=BOTH sets it to 1 GB. Option B (ALTER DATABASE) is invalid for this parameter, and SCOPE=VECTOR isn't a valid scope. Option C (SCOPE=SGA) isn't a scope value; valid scopes are MEMORY, SPFILE, or BOTH. Option D (RESET) reverts to default, not sets a value. In a PDB, this must be executed in the PDB context, not CDB, and BOTH ensures durability-key for production environments where vector workloads demand consistent memory.
질문 # 55
What is the primary purpose of the VECTOR_EMBEDDING function in Oracle Database 23ai?
- A. To generate a single vector embedding for data
- B. To calculate vector distances
- C. To serialize vectors into a string
- D. To calculate vector dimensions
정답：A
질문 # 56
Which operation is NOT permitted on tables containing VECTOR columns?
- A. SELECT
- B. DELETE
- C. JOIN ON VECTOR columns
- D. UPDATE
정답：C
설명：
In Oracle 23ai, tables with VECTOR columns support standard DML operations: SELECT (A) retrieves data, UPDATE (B) modifies rows, and DELETE (C) removes rows. However, JOIN ON VECTOR columns (D) is not permitted because VECTOR isn't a relational type for equality comparison; it's for similarity search (e.g., via VECTOR_DISTANCE). Joins must use non-VECTOR columns. Oracle's SQL reference restricts VECTOR to specific operations, excluding direct joins.
질문 # 57
What is the advantage of using Euclidean Squared Distance rather than Euclidean Distance in similarity search queries?
- A. It supports hierarchical partitioning of vectors
- B. It guarantees higher accuracy than Euclidean Distance
- C. It is the default distance metric for Oracle AI Vector Search
- D. It is simpler and faster because it avoids square-root calculations
정답：D
설명：
Euclidean Squared Distance (L2-squared) skips the square-root step of Euclidean Distance (L2), i.e., ∑(xi - yi)² vs. √∑(xi - yi)². Since the square root is monotonic, ranking order remains identical, but avoiding it (C) reduces computational cost, making queries faster-crucial for large-scale vector search. It's not the default metric (A); cosine is often default in Oracle 23ai. It doesn't relate to partitioning (B), an indexing feature. Accuracy (D) is equivalent, as rankings are preserved. Oracle's documentation notes L2-squared as an optimization for performance.
질문 # 58
A machine learning team is using IVF indexes in Oracle Database 23ai to find similar images in a large dataset. During testing, they observe that the search results are often incomplete, missing relevant images. They suspect the issue lies in the number of partitions probed. How should they improve the search accuracy?
- A. Re-create the index with a higher EFCONSTRUCTION value
- B. Add the TARGET_ACCURACY clause to the query with a higher value for the accuracy
- C. Increase the VECTOR_MEMORY_SIZE initialization parameter
- D. Change the index type to HNSW for better accuracy
정답：B
설명：
IVF (Inverted File) indexes in Oracle 23ai partition vectors into clusters, probing a subset during queries for efficiency. Incomplete results suggest insufficient partitions are probed, reducing recall. The TARGET_ACCURACY clause (A) allows users to specify a desired accuracy percentage (e.g., 90%), dynamically increasing the number of probed partitions to meet this target, thus improving accuracy at the cost of latency. Switching to HNSW (B) offers higher accuracy but requires re-indexing and may not be necessary if IVF tuning suffices. Increasing VECTOR_MEMORY_SIZE (C) allocates more memory for vector operations but doesn't directly affect probe count. EFCONSTRUCTION (D) is an HNSW parameter, irrelevant to IVF. Oracle's IVF documentation highlights TARGET_ACCURACY as the recommended tuning mechanism.
