  2. b) NUMBERED

  3. c) LINEAR

  4. d) NONINDEXED

Show answer
Correct Option: A

The default cluster type is

technology mainframe

  1. a) ESDS

  2. b) RRDS

  3. c) LDS

  4. d) KSDS

Show answer
Correct Option: D
Explanation:

To answer this question, the user needs to have knowledge of the different types of datasets in mainframe.

The default cluster type in mainframe is KSDS (Key Sequenced Dataset).

Option A) ESDS (Entry Sequenced Dataset) is incorrect because it is not the default cluster type.

Option B) RRDS (Relative Record Dataset) is incorrect because it is not the default cluster type.

Option C) LDS (Linear Dataset) is incorrect because it is not a type of clustered dataset.

Option D) KSDS (Key Sequenced Dataset) is the correct answer. It is the default cluster type used in mainframes.

Therefore, the answer is: D. KSDS.

The REPLACE parameter causes

technology mainframe

  1. a) KSDS records to be replaced by an input record with the same key

  2. b) ESDS records to be replaced by an input record with the same RBA

  3. c) RRDS records to be replaced by an input record with the same RRN

  4. d) a and c

Show answer
Correct Option: C

Which of the following entry names are valid for ALTER FREESPACE?

technology mainframe

  1. a) Cluster name

  2. b) Data component name

  3. c) Index component name

  4. d) b and c

Show answer
Correct Option: B

When defining a KSDS, the best place to specify CISZ is generally

technology mainframe

  1. a) At the cluster level

JCL statements that are not allowed in procs are

technology mainframe

  1. JOB, Delimiter(/*), or Null statements

  2. DD * or DATA statements

  3. Any JES2 or JES3 control statements

  4. All the above

Show answer
Correct Option: D

AI Explanation

To answer this question, we need to understand the purpose and restrictions of JCL statements within PROCs (procedures).

JCL (Job Control Language) is a scripting language used to define and control batch jobs in mainframe systems. PROCs, also known as procedures or job templates, are reusable sets of JCL statements that can be invoked by multiple jobs.

When using PROCs, there are certain JCL statements that are not allowed within them. Let's go through each option to understand why it is correct or incorrect:

Option A) JOB, Delimiter(/), or Null statements - This option is incorrect. JOB, Delimiter(/), or Null statements are allowed in PROCs. These statements are used to define the job and its attributes.

Option B) DD * or DATA statements - This option is incorrect. DD * or DATA statements are allowed in PROCs. These statements are used to specify input and output data sets for the job steps.

Option C) Any JES2 or JES3 control statements - This option is incorrect. JES2 (Job Entry Subsystem 2) and JES3 (Job Entry Subsystem 3) control statements are allowed in PROCs. These statements are used to control the execution and management of jobs.

Option D) All the above - This option is correct. None of the statements mentioned in the options (JOB, Delimiter(/*), Null statements, DD *, DATA statements, JES2 or JES3 control statements) are disallowed in PROCs. Therefore, the correct answer is D.

In summary, the JCL statements mentioned in the options (JOB, Delimiter(/*), Null statements, DD *, DATA statements, JES2 or JES3 control statements) are all allowed in PROCs.
