Question #6
You have been tasked to create a table for a banking application.
One of the columns must meet three requirements:
1. Be stored in a format supporting date arithmetic without using conversion functions
2. Store a loan period of up to 10 years
3. Be used for calculating interest for the number of days the loan remains unpaid
Which data type should you use?
  1. A
    INTERVAL YEAR TO MONTH
  2. B
    INTERVAL DAY TO SECOND
  3. C
    TIMESTAMP WITH LOCAL TIMEZONE
  4. D
    TIMESTAMP
  5. E
    TIMESTAMP WITH TIMEZONE

Correct Answer:
B
chatbot-img GPT-4o - Answer
B, INTERVAL DAY TO SECOND, is the optimal choice for the data type in this scenario. This data type allows precise calculations for the duration in days, which is essential for computing interest based on the days a loan remains unpaid. It naturally supports date arithmetic, making it ideal for handling situations where the duration needs to be calculated without extra conversion functions. This feature is crucial in banking applications where accuracy and efficiency in date-related calculations are required.

Question #7
In the spfile of a single instance database, LOCAL_LISTENER is set to LISTENER_1.
The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains:

Which statement is true?
  1. A
    Dynamic service registration cannot be used for this database instance
  2. B
    The LREG process registers services dynamically with the LISTENER_1 listener
  3. C
    LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration
  4. D
    There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database instances
  5. E
    The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration

Correct Answer:
C

Question #8
Which three statements are true concerning logical and physical database structures? (Choose three.)
  1. A
    All tablespaces may have one or more data files
  2. B
    The extents of a segment must always reside in the same datafile
  3. C
    A smallfile tablespace might be bigger than a bigfile tablespace
  4. D
    A segment can span multiple data files in some tablespaces
  5. E
    A segment's blocks can be of different sizes
  6. F
    A segment might have only one extent
  7. G
    Segments can span multiple tablespaces

Correct Answer:
CDF
chatbot-img GPT-4o - Answer
Correct choices C, D, and F expound accurately on Oracle’s database structures. Regarding C, while bigfile tablespaces typically contain a single large datafile, smallfile tablespaces can contain multiple datafiles that collectively may surpass the size of a bigfile's datafile. For D, a segment's ability to span multiple data files within certain types of tablespaces (chiefly locally managed ones) allows flexibility in storage management. Lastly, F is valid because a segment may indeed consist of only a single extent if its data requirements are sufficiently compact to fit within one extent's limits, proving efficiency in space usage within the database. These insights are crucial for understanding the configuration and optimization of Oracle database storage.

Question #9
Which two statements are true regarding a SAVEPOINT? (Choose two.)
  1. A
    Rolling back to a SAVEPOINT can undo a CREATE INDEX statement
  2. B
    Rolling back to a SAVEPOINT can undo a TRUNCATE statement
  3. C
    Only one SAVEPOINT may be issued in a transaction
  4. D
    A SAVEPOINT does not issue a COMMIT
  5. E
    Rolling back to a SAVEPOINT can undo a DELETE statement

Correct Answer:
DE
chatbot-img GPT-4o - Answer
Savepoints are very handy in managing transactions, particularly when only partial rollbacks are required. Unlike DDL commands like CREATE INDEX or TRUNCATE, which automatically commit a transaction, DML statements such as DELETE can be rolled back. This flexibility is vital in scenarios where undoing specific operations without affecting others is necessary. Also, it's good to remember that issuing a savepoint within a transaction does not result in a COMMIT. Hence, any changes made after a savepoint can be undone, up to the point of the last established savepoint.

Question #10
Which three functions are performed by dispatchers in a shared server configuration? (Choose three.)
  1. A
    writing inbound request to the common request queue from all shared server connections
  2. B
    checking for outbound shared server responses on the common outbound response queue
  3. C
    receiving inbound requests from processes using shared server connections
  4. D
    sending each connection input request to the appropriate shared server input queue
  5. E
    broadcasting shared server session responses back to requesters on all connections
  6. F
    sending shared server session responses back to requesters on the appropriate connection

Correct Answer:
ACD
chatbot-img GPT-4o - Answer
In a shared server configuration, dispatchers perform several crucial roles. Firstly, they receive inbound requests from clients, which is central to their function. Once a request is received, dispatchers are responsible for placing these requests into the common request queue where shared servers can access them. Furthermore, the requests are also routed to the appropriate shared server input queue to ensure they are processed efficiently. Choices like managing individual connection queues or broadcasting responses to all connections are not functions performed by dispatchers in this context.
