Three of the 178 questions in this pack

Question 1

You execute this command: Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace? (Choose two.)

  1. AUTOEXTEND is possible for the datafile
  2. It must be bigger than the largest SMALLFILE tablespace
  3. Additional data files may not be added
  4. It will be a dictionary-managed tablespace by default
  5. It will always have a 32K blocksize
Show answer and explanation

Correct answer: A, C. AUTOEXTEND is possible for the datafile; Additional data files may not be added

A BIGFILE tablespace can contain a single datafile that can grow up to 4GB (or larger depending on the block size), and this datafile supports AUTOEXTEND to enable automatic growth. However, additional datafiles cannot be added to a BIGFILE tablespace by definition, it is designed to have only one datafile. In contrast, SMALLFILE tablespaces can have multiple datafiles. Therefore, both A (AUTOEXTEND is possible) and C (additional datafiles may not be added) are correct statements about the BIG_TBS tablespace.

Why the other options are wrong

  • B. A BIGFILE tablespace does not have size restrictions relative to SMALLFILE tablespaces; the relationship works the opposite way since BIGFILE can be much larger.
  • D. Oracle 10g and later default to locally-managed tablespaces, not dictionary-managed tablespaces.
  • E. The blocksize of a BIGFILE tablespace is determined by the DB_BLOCK_SIZE parameter and is not required to be 32K; it defaults to whatever the database blocksize is configured to be.

Question 2

Which statement is true about the INTERSECT operator used in compound queries?

  1. Multiple INTERSECT operators are not possible in the same SQL statement
  2. It processes NULLs in the selected columns
  3. INTERSECT is of lower precedence than UNION or UNION ALL
  4. It ignores NULLs
Show answer and explanation

Correct answer: B. It processes NULLs in the selected columns

The INTERSECT operator processes NULLs in the selected columns, treating NULL as a distinct value that can be matched. When comparing rows from two result sets, INTERSECT will return rows where NULL values in corresponding columns match NULL values from the other set. This is the defining characteristic of how INTERSECT handles NULL values differently from some other SQL operations.

Why the other options are wrong

  • A. Multiple INTERSECT operators are absolutely possible in the same SQL statement; you can chain multiple INTERSECT operations together.
  • C. INTERSECT has the same precedence as UNION and UNION ALL; they are evaluated left to right with equal priority.
  • D. INTERSECT does not ignore NULLs; it actively processes and matches them as comparable values.

Question 3

Which three statements are true about advanced connection options supported by Oracle Net for connection to Oracle Database instances? (Choose three.)

  1. Connect Time Failover requires the use of Transparent Application Failover (TAF)
  2. Source Routing requires the use of a name server
  3. Source Routing enables the use of Connection Manager (CMAN) which enables network traffic to be routed through a firewall
  4. Load Balancing can balance the number of connections to dispatchers when using a Shared Server configuration
  5. Load Balancing requires the use of a name server
  6. Connect Time Failover requires the connect string to have two or more listener addresses configured
Show answer and explanation

Correct answer: B, C, F. Source Routing requires the use of a name server; Source Routing enables the use of Connection Manager (CMAN) which enables network traffic to be routed through a firewall; Connect Time Failover requires the connect string to have two or more listener addresses configured

Source Routing enables the use of Connection Manager (CMAN) which routes network traffic through firewalls (B and C are both correct). Connect Time Failover requires the connect string to have two or more listener addresses so the client can automatically attempt connection to the next address if the first fails (F). TAF is not required for Connect Time Failover, TAF is a separate feature for maintaining connections after initial connection is established.

Why the other options are wrong

  • A. Connect Time Failover operates independently and does not require Transparent Application Failover (TAF).
  • D. Load Balancing can balance connections to instances or listeners, but the statement about dispatchers specifically is not accurate for standard load balancing.
  • E. Load Balancing does not require a name server; it can function with local connect descriptors and multiple addresses.

What makes the 1Z0-082 hard

1Z0-082 is the first half of the Oracle DBA OCP path, and it is two exams wearing one code: half administration, half SQL, and candidates reliably prepare for only the half they work in.

The admin half lives in the architecture: instance memory structures and background processes, startup and shutdown stages, tablespace and undo management, users, roles and profiles, and the network stack of listeners and naming. The SQL half re-tests 1Z0-071-grade material. The trick questions are architectural cause and effect: what actually happens at MOUNT, or when undo runs out mid-transaction.

About the exam

1Z0-082 certifies Oracle Database administration fundamentals and SQL: architecture, instance management, storage, users and security, and networking. Passing it plus 1Z0-083 earns the Oracle Database Administration 2019 Certified Professional credential. Does not expire.
