IBM MQ v9.4 Administrator - Professional 認定 C1000-200 試験問題:
1. Which explanation best describes IBM MQ's publish/subscribe model in complex enterprise environments, including how topics are created, how multiple subscribers can independently receive messages, and how this architecture supports loosely coupled, scalable, and event-driven messaging across multiple systems?
A) Publish/subscribe sends messages to a single queue for one subscriber
B) Publish/subscribe uses topics to allow multiple subscribers to receive messages independently, enabling scalable, loosely coupled, event-driven communication
C) Publish/subscribe requires subscribers to request messages manually from the publisher
D) Publish/subscribe is only used for logging and not for message delivery
2. If an IBM MQ administrator wants to ensure that messages are encrypted in transit and only authorized applications can connect to the queue manager over an untrusted network, which combination of channel type and security feature is required to achieve both encryption and authentication simultaneously?
A) Sender-receiver channels with SSL/TLS and certificate-based authentication
B) Cluster channels with IP filtering only
C) Alias queues without security configuration
D) Temporary queues with password protection
3. In IBM MQ, when an application requires messages to be stored durably so that they survive system failures and restart scenarios, which configuration must be applied to the message or queue to guarantee this level of reliability?
A) Non-Persistent Mode
B) Persistent Messaging
C) Temporary Queue Assignment
D) Volatile Queue Storage
4. A bank is transmitting sensitive payment instructions between queue managers located in two different countries. Security policies mandate encryption, authentication, and integrity of all transmitted messages without relying solely on application-level encryption. Which IBM MQ feature ensures compliance with this requirement?
A) Segmented queues with persistence
B) Priority messaging with authorization
C) SSL/TLS-enabled channels with MCA security
D) Non-persistent queues with retries
5. IBM MQ supports message selectors for filtering messages. Which option correctly explains how message selectors function, including their limitations and typical usage in message-driven applications?
A) Message selectors encrypt messages selectively to ensure secure delivery to specific applications.
B) Message selectors are expressions evaluated by the queue manager to allow an application to receive only messages that match specific criteria, based on message headers or properties.
C) Message selectors are applied at the queue manager level and filter messages before they enter any queue, affecting all consuming applications.
D) Message selectors automatically archive messages that do not match criteria for later processing.
