C1000-058 Sample Questions & Answers
Object configuration is weighted most, alongside queue manager administration, setting up high availability, monitoring and tuning performance, planning installations and migrations, diagnosing problems, and securing the queue manager.

- Question 1Advanced
Problem Determination · Locate error logs and FFST files
An administrator observes that the
/var/mqm/errorsdirectory is consuming excessive disk space due to a large number of FDC files generated by a repeating error. The administrator needs to stop the generation of FDC files for this specific probe ID temporarily while investigating the root cause.Which configuration change should be applied?
Show answer & explanation
Correct answer: C
While suppressing specific probes is complex, the standard method to reduce FDC noise for known errors is using the
SuppressMessageorExcludeMessageattribute in the Diagnostic stanza of qm.ini/mqs.ini. - Question 2Intermediate
Configuration · Configure JMS support
A developer needs to configure a JMS Connection Factory in IBM MQ that connects to a multi-instance queue manager
QM_HA. The queue manager runs onhost1(port 1414) andhost2(port 1414).Which connection list syntax is correct for the
CONNECTIONNAMELISTproperty?Show answer & explanation
Correct answer: A
The CONNECTIONNAMELIST property accepts a comma-separated list of host(port) entries. The client will try these in order or based on client reconnection logic.
- Question 3Advanced
Availability · Create HA RDQM topologies
An administrator is setting up a Replicated Data Queue Manager (RDQM) for Disaster Recovery (DR) between two sites. The primary site is 'SiteA' and the recovery site is 'SiteB'. The synchronization link has been established.
Which command must be run on the primary node to configure the DR role initially?
Show answer & explanation
Correct answer: D
The
crtmqmcommand with-rr pspecifies the 'primary' role for DR.-rldefines the local replication IP and-ridefines the remote replication IP. - Question 4Intermediate
Performance Tuning · Tune object definitions and channel parameters
A financial application requires a strictly ordered message flow where 'Request' messages must be processed before 'Update' messages. The messages are being sent to a cluster queue
APP.QUEUEhosted on three queue managers.Which configuration ensures that all messages from a specific sending application instance are routed to the same destination queue manager to maintain order?
Show answer & explanation
Correct answer: A
DEFBIND(OPEN) fixes the destination at the time the queue is opened (MQOPEN). All subsequent MQPUTs using that object handle go to the same destination queue manager, preserving logical grouping/affinity.
- Question 5Advanced
Configuration · Configure channels based on network topology
Case Study: Global Retailer 'ShopFast'
Background
ShopFast is migrating its inventory system to IBM MQ V9.1. They operate two data centers: New York (NY) and London (LDN). The network between them has high latency (approx 80ms).Requirement
Applications in NY need to send stock updates to LDN. The updates are critical; no data loss is permitted. However, the NY application cannot block waiting for confirmation from LDN due to the high network latency. The solution must ensure that once the NY application commits the message locally, it is guaranteed to reach LDN eventually.Constraint
The disk storage in NY is high-performance SSD, while LDN uses standard HDD.Which channel and queue configuration best meets these requirements?
Show answer & explanation
Correct answer: B
Putting to a remote queue is asynchronous for the application (it puts to the local transmission queue). Persistent messages ensure no data loss. NPMSPEED(NORMAL) ensures data integrity for non-persistent messages too, though here persistence is key. The channel handles the latency asynchronously.
- Question 6Intermediate
Monitoring · Enable and monitor IBM MQ events
An MQ administrator needs to monitor the current depth of the queue
APP.INPUTevery 60 seconds and generate an event if it exceeds 5000 messages. The queue manager isQM1.Which sequence of MQSC commands correctly configures this monitoring?
Show answer & explanation
Correct answer: B
PERFMEV(ENABLED) on the queue manager enables performance events globally. Setting QDPHIEV(ENABLED) and QDEPTHHI(5000) on the specific queue triggers the 'Queue Depth High' event when the threshold is breached.
- Question 7IntermediateSelect 2
Availability · Configure multi-instance queue manager setups
Which TWO of the following are valid requirements for configuring a Multi-Instance Queue Manager (MIQM) on Linux? (Select TWO)
Show answer & explanation
Correct answers: B, E
MIQM relies on the file system to manage the active/standby lock. NFS v4 provides robust lease-based locking required for this.
Since files are shared, file ownership permissions on the shared storage must align. The UID/GID numbers must match on both servers.
- Question 8Intermediate
Security · Configure end-to-end message security
A new regulation requires that all messages on the queue
FINANCE.TRANSACTIONSmust be digitally signed to ensure integrity, but encryption is not required. The administrator decides to use IBM MQ Advanced Message Security (AMS).What is the correct quality of protection (QOP) setting for the security policy?
Show answer & explanation
Correct answer: B
The INTEGRITY QOP provides digital signing (hashing and signing) to detect tampering, but does not encrypt the message payload.
- Question 9Beginner
Planning, Installation, and Migration · Deploy in Docker containers
True or False: When using IBM MQ in a Docker container, the
/var/mqmdirectory should be mounted as a persistent volume to ensure that queue manager data and logs survive container restarts.Show answer & explanation
Correct answer: A
Docker containers are ephemeral. Without mounting
/var/mqm(or the specific data directories) as an external volume, all messages and configuration changes would be lost when the container stops. - Question 10Intermediate
Security · Configure Channel Authentication
A developer reports that they are unable to connect to the queue manager
QM_TESTusing a client application. The administrator checks the error logs and seesAMQ9999: Channel 'SRV.CONN' to host '192.168.1.50' ended abnormally.The administrator suspects a CHLAUTH rule is blocking the connection. Which command helps verify the effective channel authentication rule for this specific incoming connection?
Show answer & explanation
Correct answer: D
The
MATCH(RUNCHECK)parameter simulates the connection matching logic against existing CHLAUTH rules and reports which rule (block or map) applies to the provided address and user.
