Sample Oracle 1Z0-183 Practice Questions

Try these sample questions to review concepts for the Oracle 1Z0-183 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 161+ question experience with AI tutoring.

1Which Oracle tool generates a snapshot-based report comparing two points in time to diagnose overall database performance, showing top wait events, SQL by elapsed time, and instance statistics?
A.AWR report
B.Data Pump
C.OPatch
D.SQL Loader
Explanation: The Automatic Workload Repository (AWR) report compares two snapshots and summarizes top timed events, load profile, and high-load SQL over the interval. It is the primary starting point for instance-level performance diagnostics.
2An AWR report shows that the top timed event is 'db file sequential read' consuming most of the DB time. What does this wait event most directly indicate?
A.Single-block physical reads, typically from index access
B.Network latency to the client
C.Contention on the redo log buffer
D.CPU starvation on the server
Explanation: 'db file sequential read' is the wait for single-block reads, most often caused by index lookups and table access by ROWID. High values usually point to physical I/O on indexed access paths that may benefit from caching or SQL tuning.
3Which advisor analyzes an AWR snapshot range automatically and produces findings and recommendations such as 'high I/O' or 'undersized SGA' to address the most significant performance problems?
A.Automatic Database Diagnostic Monitor (ADDM)
B.SQL Access Advisor
C.Segment Advisor
D.Undo Advisor
Explanation: ADDM analyzes AWR data and identifies the root causes of performance problems, ranking findings by impact on DB time and offering recommendations. It runs automatically after each AWR snapshot by default.
4You want to capture a known-good execution plan for a SQL statement and prevent the optimizer from using a worse plan after statistics change. Which feature should you use?
A.SQL Plan Management (SQL plan baselines)
B.Result Cache
C.Flashback Query
D.Database In-Memory
Explanation: SQL Plan Management stores accepted plans as SQL plan baselines. The optimizer will only use a baseline plan and will evolve new plans only after they are verified to perform at least as well, protecting against plan regressions.
5Which Real Application Testing component captures production SQL workload and replays it on a test system to assess the impact of a change such as an upgrade?
A.Database Replay
B.SQL Performance Analyzer
C.Active Session History
D.SQL Tuning Set
Explanation: Database Replay captures the full concurrent workload on production and replays it with the same timing and concurrency on a test system, allowing you to evaluate the impact of system changes before applying them in production.
6To populate tables into the In-Memory Column Store so analytic queries scan them in a columnar format, which clause do you add to the table definition?
A.INMEMORY
B.CACHE
C.COMPRESS FOR OLTP
D.NOLOGGING
Explanation: Marking a table or partition with the INMEMORY clause enables it for the In-Memory Column Store (IM column store), where data is stored in a compressed columnar format optimized for analytic scans and joins.
7A DBA wants lightweight, always-on sampling of active sessions to diagnose a transient performance spike that already ended. Which feature provides this historical session-level detail?
A.Active Session History (ASH)
B.Automatic Workload Repository baselines
C.Statspack
D.V$SESSION only
Explanation: Active Session History samples active sessions every second and retains the data in memory and AWR, letting you analyze short-lived spikes by time, SQL_ID, session, and wait event even after the event has passed.
8Which advisor accepts a SQL Tuning Set or single statement and may recommend SQL profiles, new indexes, or restructured SQL to improve performance?
A.SQL Tuning Advisor
B.ADDM
C.Memory Advisor
D.MTTR Advisor
Explanation: The SQL Tuning Advisor performs automatic tuning of high-load SQL and can recommend SQL profiles, index creation, statistics gathering, or SQL restructuring. It can be run manually or as the Automatic SQL Tuning task.
9Adaptive query optimization in Oracle can change a join method at runtime when actual row counts differ greatly from estimates. What is this specific capability called?
A.Adaptive plans
B.Bind peeking
C.Cursor sharing
D.Plan stability
Explanation: Adaptive plans allow the optimizer to defer the final plan decision (for example, choosing between a nested loop and a hash join) until execution, switching based on the actual number of rows seen during execution.
10Which initialization parameter sets a target for the time, in seconds, that instance recovery should take, influencing how aggressively checkpoints are written?
A.FAST_START_MTTR_TARGET
B.DB_CACHE_SIZE
C.OPEN_CURSORS
D.PROCESSES
Explanation: FAST_START_MTTR_TARGET specifies the desired mean time to recover (in seconds) after instance failure. Oracle adjusts checkpoint writing so that the redo to be applied during crash recovery stays within this target.

Oracle 1Z0-183: Suggested Study Strategy

1Work through every objective hands-on in a 23ai environment: create a CDB and PDBs with DBCA, clone and relocate PDBs, and configure local and CDB resource plans rather than just reading about them.
2Practice RMAN end to end on a test database: configure retention and the FRA, take incremental backups, then deliberately lose a datafile, control file and the SPFILE and recover each one.
3Learn the performance-tuning toolchain in order of use: enable AWR baselines, read an AWR report, run ADDM, then apply the SQL Tuning Advisor and SQL Plan Management to lock in good plans.
4Spend real time on the new 23ai features, especially AI Vector Search (VECTOR columns, vector indexes, VECTOR_DISTANCE) and JSON-Relational Duality Views, as part of the published 2025 new-features objective.
5Memorize the Flashback family and what each one needs: Flashback Database (flashback logs and FRA), Flashback Table (row movement and undo) and Flashback Query (undo retention).
6Practice AutoUpgrade and OPatch workflows for patching and upgrades, and know the difference between Release Updates and Release Update Revisions and how Oracle Restart fits into the deployment.
7Review multitenant administration: know PDB cloning, application containers, and lockdown profiles
8Master RMAN recovery scenarios: practice complete recovery, PITR, and flashback database in a lab environment
9Understand TDE keystores: software keystore vs. hardware HSM, auto-login vs. password-protected, tablespace vs. column encryption
10Study ASM architecture: disk groups, failure groups (mirroring), rebalance operations, and ACFS filesystem
11Know Oracle 23ai new features tested on exam: AI Vector Search (VECTOR type, DBMS_VECTOR), JSON Duality Views, True Cache, Schema Privileges
12Check release-specific behaviour against current AI Database documentation; older 23ai lab examples do not establish current 26ai support for every feature.

How should I prepare?

Use the current Oracle MyLearn path, which advertises 75+ training hours, and practise administration tasks in a disposable lab. Allocate additional time according to your experience; OpenExamPrep’s schedule is a planning estimate.

How long is certification valid?

A fixed validity period for 1Z0-183 was not verified. Oracle’s guidelines say certain Database credentials need recertification to remain active; check the credential’s current CertView status and applicable policy.

Are these official Oracle questions?

These are independent OpenExamPrep questions for learning and review. Use Oracle’s official objectives, documentation, and current training materials as the authoritative references.
