What three statements are true with regards to restartable mode for an FTP Enterprise stage? (Select three)

• A. Checkpoint files are written to /^"checkpoint directory">/pftpJobid_ <"jobid number">.
• B. File URIs that were transferred completely are not transferred again.
• C. Specify the-restartable_transfer option.
• D. Specify a checkpoint directory for the transfer using the -checkpointdir directory.
• E. Optionally specify a unique job_id for the transfer.

A client has multiple servers connected with a high bandwidth switch and has installed DataStage on one of them. There are five files (with the same record layout) that must be retrieved from three other servers using FTP. Which approach will retrieve and process all five files in the minimal amount of time?

• A. Use a single FTP Enterprise stage and specify five URI properties (one for each file). Next, process the records without landing to disk.
• B. Create a sequence containing five separate DataStage jobs which each retrieve a single file and append it to a common Data Set. Next, process the resulting Data Set in an sixth DataStage job.
• C. In a single job, use three separate FTP Enterprise stages (one for each machine) with output links to a single Sort Funnel stage. Next, process the records without landing to disk.
• D. In a single job, use five separate FTP Enterprise stages with output links to a single Sort Funnel stage. Next, process the records without landing to disk.

You have a 3TB dataset hash-partitioned on CustID in a clustered environment. You need to join this dataset with 1GB of reference data on OrderID. Which technique is most appropriate?

• A. Use Join stage, hash-partition and sort both link on OrderID.
• B. Use Lookup stage, select auto partitioning for the stream link and hash-partition the reference link on CustI
• C. Use Lookup stage, select auto partitioning for both link.
• D. Use Lookup stage, select auto partitioning for the stream link and entire partitioning for the reference link.

You would like to invoke a job sequence from a web service. How can this be done?

• A. Invoke the job sequence using the dsjob command.
• B. Create a DataStage routine that invokes the job sequence and invoke the routine from a DataStage job. Then use this job when creating the web service operation.
• C. Check the use job sequence checkbox when creating the web service.
• D. Select the job sequence when creating the web service operation,

You would like to run a particular processing job within a job sequence for each weekday of the week. How could you do this? (Select two)

• A. Set the frequency property in the job scheduler to weekdays only.
• B. Call a routine in the job sequencer that starts the processing job for each day you would like to process.
• C. Start Loop and End Loop activity stages on the job sequencer canvas where you loop through the days and pass a value for each day into the job via parameter.
• D. Have a parameter set that contains the days of the week you would like to process and routine to parse the days of the week contained in the "day" parameter.
