Sample exam questions turn tutorial reading into exam reflexes: you recognize why 2035 is authorization not network, why a sender channel in BINDING is not fixed by increasing MAXDEPTH, and why DISABLE CHLAUTH is almost never the right multiple-choice answer. IBM certification items often wrap these facts in short scenarios—a bank batch job, a channel after firewall change, a Java client after queue manager migration. This page provides original practice questions grouped for administrator and developer study, scenario-style prompts, answer explanations, and a large TutorialQuiz for repeated drills. These are not leaked real exam items; they mirror skills IBM lists in public objective guides. Use them after hands-on labs and before paying exam fees.
A remote application connects to SVRCONN CHAN.APP on QM1. CHLAUTH is ENABLED. The client asserts user bob. BLOCKUSER lists bob. The connection fails before RUNNING. What is the best fix?
Answer: B. BLOCKUSER exists to block specific asserted IDs. Disabling CHLAUTH (A) removes enterprise controls. C and D do not address authentication policy.
Messages on QREMOTE PAY.TO.PARTNER route to QM2. CURDEPTH on SYSTEM.TRANSMIT.QM2 grows. SDR channel to QM2 is INACTIVE. Applications successfully MQPUT to PAY.TO.PARTNER. What should the administrator do first?
Answer: B. Messages accumulate on XMITQ until the sender channel moves them. PUT succeeds locally; movement is channel responsibility.
Producers receive MQRC indicating logging not available. DISPLAY QMSTATUS shows log utilization critical. Disk on log volume is full. Best immediate action pair?
Answer: B. Never delete active logs (A) without IBM support guidance. C and D are unrelated.
An application MQPUTs three messages under syncpoint, then calls MQBACK. What happens to the three messages?
Answer: B. MQBACK rolls back the UOW unless a broken transaction requires admin resolution.
A server program replies to requests. Clients report duplicate replies after restart. Which design weakness is most likely?
Answer: A. Correlation ties reply to request; missing correlation causes wrong delivery or retries that look like duplicates when consumers are not idempotent.
MQOPEN returns MQRC 2035. The application user should have access. The queue manager uses CHLAUTH on SVRCONN. What should the developer verify with the administrator?
Answer: A. 2035 is not authorized—effective identity after channel security may differ from the developer laptop username.
| Symptom | First step |
|---|---|
| 2059 connection broken | Channel/listener status, host, port, firewall |
| 2085 unknown object | DISPLAY QLOCAL, spelling, QM name |
| Channel RETRY loop | AMQERR both sides, CHLAUTH, TLS |
| Poison message loop | BACKOUTTHRESH, DLQ, consumer fix |
| Slow restart after crash | Log replay size, checkpoint tuning |
Use the quiz below as a ten-minute drill. Aim for eight of ten correct before mixing administrator and developer certifications in one sitting.
Practice questions are flashcards for grown-ups—you see a problem story and pick the fix before the real test asks the same kind of story.
