Question 2

A distributed task fails with a DSNL511I error, a TCP/IP conversation has failed. Thisproblem was not

resolution of this issue?

Question 4

A customer is performing a traditional image copy disaster recovery test. The systemsprogrammer
creates a conditional restart control record (CRCR) but detects an error before starting DB2. Which action
should be performed to correct the CRCR record?

A. First use CRESTART,DELETE to delete the error CRCR record then CRESTART,CREATE to add a
new one. B. Start DB2, reply "M" to the WTOR that is displayed from the first CRCR record to modify the CRCR
parameters. C. Use CRESTART,MODIFY to modify the parameters of the error CRCR record. D. Use CRESTART,CREATE to create a new CRCR record.

Question 5

A customer write-up on business processes includes a description of handling requests for new user
identities or changes to identities. These processes are handled in different ways by different disciplines.
For example, there is an RACF team to handle processing of RACF identities and a UNIX team to handle
processing of UNIX identities. From a process standpoint, all these processes are documented. They
allinvolve assessments and approval processes. The customer seems fairly happy with how these
processes are running. They are however receiving complaints that the process of issuing identities and
updating identities is slow. Which two value propositions might you present to this customer that relate to
their situation? (Choose two.)

A. Keeping these processes separate and distinct allows them to be focused on individually and have
process improvements that are particular to each involved area (RACF, UNIX, etc.). B. Automating the user provisioning processes can shorten the provisioning cycle, increase satisfaction,
and reduce help desk calls. C. Introducing intrusion detection will help the customer more quickly determine if their various disciplines
are under attack or not. D. Managing the user provisioning processes with an enterprise-spanning solution offers efficiencies and
increases effectiveness. E. Using automation to synchronize user information across platforms will reduce erroneous information
and improve business and application processing.

Question 6

A customer is having performance problems with a particular statically bound batch package.
This batch program is processing transactions from a sequential file where each input record ends up
updating one row in a 10 million row table. The sequential file contains 5000 records.
The customer reviews the accounting record information and notices that class 1 elapsed time is 2 hours,
class 2 elapsed time is 1 hour 50 minutes and class 3 elapsed time is 1 hour, 45 minutes. Which
statement regarding the problem could be true?

A. The batch program appears to have a logic error; the difference between class 2 elapsed and class 3
elapsed shows only 5 minutes of time actually executing in DB2. B. DASD contention could be the result of the poor performance problem. C. The access path for the package is not optimal; high CPU is causing the problem. D. The scenario as described does not indicate that there is a performance problem; all of the elapsed
time figures appear to be normal.
