Developers migrating applications to IBM i must understand the differences between library and IFS storage. Which of the following statements correctly describes how the backup and recovery processes differ between libraries and IFS?


  1. Libraries can only be backed up using BRMS, while IFS can use any backup utility.

  2. IFS does not support incremental backups, while libraries do.

  3. Both libraries and IFS have the same backup process but differ in file access methods.

  4. Libraries are backed up through system-level commands, while IFS requires user-defined scripts.

Answer: C


Explanation: The backup processes for libraries and IFS are fundamentally similar, using system-level commands for backup, while their access methods differ based on their organizational structure.

everts the database to a previous state and discards all changes made during the transaction. auses the transaction, allowing for further changes.

rovides a way to review changes before committing. er: B

nation: The "ROLLBACK" statement is used to revert the database to its previous state by ding all changes made during the transaction, effectively undoing any operations performed.

    When developing ILE RPG applications, which of the following statements accurately describes the importance of the "CRTDSK" command in the context of data structure initialization and management?


    1. CRTDSK is only used for defining static data structures.

    2. CRTDSK is essential for defining data structures that can manage file records efficiently.

    3. CRTDSK allows for dynamic allocation of data structures during runtime.

    4. CRTDSK is irrelevant in the context of ILE RPG programming. Answer: B

    Explanation: The CRTDSK command is essential for defining data structures that can efficiently manage file records, which is crucial for ILE RPG applications that perform file I/O operations.


    Question: 421


    When defining procedures within an ILE service program, which of the following is the correct way to ensure that a procedure is callable from other ILE programs?


    1. Procedures must be defined as *EXPORT to be callable from external programs.

      xecution of SQL stored procedures, how does the SET statement differ from the SELECT INTO ent when assigning values to variables?


      SET statement can only assign scalar values, while SELECT INTO can assign multiple val SELECT INTO statement is used for row-based assignments, while SET is for single value ments.

      SET statement does not allow for error handling, whereas SELECT INTO does. SELECT INTO statement can retrieve values from multiple tables, while SET cannot.


      er: B


      nation: The SELECT INTO statement is used for row-based assignments and can retrieve mu ns into variables, while the SET statement is typically used for single scalar value assignmen

      them suitable for different scenarios in SQL stored procedures.

      No special attributes are needed; all procedures are public by default.

    1. Transaction Output

    2. Error Logs

    3. Diagnostic Messages

    4. Summary Reports

    Answer: D


    Explanation: Summary Reports provide aggregated information that supports decision-making and operational analysis, distinguishing them from transactional outputs that detail individual transactions.


    Question: 424


    What is the significance of using OUT parameters in SQL stored procedures, and how do they differ from IN parameters in terms of data flow?


    T parameters can only be used to return multiple result sets.

    T parameters must be defined as NOT NULL to ensure data integrity.

    T parameters allow the procedure to return values to the caller, while IN parameters are use ut.


    er: D


    nation: OUT parameters in SQL stored procedures are specifically designed to return values while IN parameters are used solely for input. This distinction allows for a clear data flow b ocedure and its caller.
