  1. There is either a JCLLIB statement for the entire JOB, or a separate one for each EXEC

  2. A JCLLIB statement can not have a statement name.

  3. There can only be one JCLLIB statement per JOB.

  4. A JCLLIB statement must be coded before the first EXEC statement.
Reveal answer Fill a bubble to check yourself
C,D Correct answer
Explanation

JCLLIB statement rules: Only one JCLLIB statement per JOB is allowed (makes sense for specifying a single procedure library). It must be placed before the first EXEC statement. It can have a statement name (though rarely used). Therefore A and B are false, C and D are true.

Some parameters have sub-parameters. These can be both positional or keyword sub-parameters. Suppose TU00001 is the programmer’s name, ATUT000 is the programmer's account number and it is a default value. Given this information, which statements are correct:

  1. //TU00001T JOB (ATUT000,,,,,,,,),TU00001,CLASS=7,MSGCLASS=X

  2. //TU00001T JOB (ATUT000),’TU00001’,CLASS=7,MSGCLASS=X

  3. //TU00001T JOB TU00001,’(ATUT000)’,CLASS=7,MSGCLASS=X

  4. //TU00001T JOB ,(ATUT000),CLASS=7,MSGCLASS=X
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

In JOB statement syntax, positional parameters follow strict order: accounting info (positional 1), programmer name (positional 2 or keyword NAME), then keyword parameters. Option A uses positional for both (ATUT000 as pos1, TU00001 as pos2 via NAME keyword's positional form). Option B uses explicit keyword syntax. Both are valid. Options C and D incorrectly mix positional and keyword syntax.

DESK.cpl is the Control Panel file that opens Display Properties in Windows. The .cpl extension indicates Control Panel applets. DISPLAY.cpl, DISP.cpl, and DISPROP.cpl are not valid Windows CPL files - the correct name is DESK.cpl (short for Desktop properties). You can run it by entering 'desk.cpl' in the Run dialog or Command Prompt.

  4. Sun Solaris
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In LoadRunner architecture, the Controller (which orchestrates load tests) can be installed on UNIX systems. This is because UNIX provides stable, high-performance environments suitable for managing complex test scenarios. While LoadRunner has cross-platform components, the Controller's UNIX support is a key architectural feature for enterprise deployments.
