IBM WebSphere MQ V7.0, Solution Design Sample Questions:

1. A company is implementing a new solution on HP-UX that will send orders to the Order Processing system, which is a WebSphere MQ application on the mainframe. Which of the following configurations for the new solution on HP-UX provides the function needed for this scenario? The solution on HP-UX would run:

A) only as a server, using the WebSphere MQ server on HP-UX to access the Order Processingsystem.
B) only as a client, using the WebSphere MQ client on HP-UX to access the Order Processingsystem.
C) as a standalone application, accessing a WebSphere MQ-enabled adapter on the mainframeto access the Order Processing system.
D) as a client or full server, using either the WebSphere MQ client or a full WebSphere MQ serveron HP-UX to access the Order Processing system.

2. A weather bureau plans to offer a service to its customers whereby they can receive weather station information (e.g. temperature, humidity) up to one year old. Customer applications should be able to select from which region they want to get datA. What is the best way of implementing such a solution?

A) Store messages in separate queues for each region and use the expiration feature of themessaging system to delete outdated messages
B) Store messages in separate queues for each region and use a scheduled process to deleteoutdated messages
C) Store information in a database and access it using a publish/subscribe pattern
D) Store information in a database and access it using a request-reply pattern

3. A business requirement is brought forward for a back end server that is to send replies to requests sourced on the web and on internal application servers. The back end application will perform database lookups and formatting operations that are deemed trivial. Message sizes, traffic volumes and estimated annual growth rates are provided. The application designer is asked to provide a sizing estimate for a server that will be able to provide the response times stipulated in the SLA. Which is the fastest way to arrive at a reasonable estimate of the required server size?

A) Consult the Performance Reports from the WebSphere MQ SupportPac website forcomparable measurements and extrapolate to the specified requirements.
B) Meaningful performance measurements can only be done once the application developmenthas progressed to the point where the actual code can be benchmarked.
C) Create a suitable test program and test clients and perform a series of benchmarks on anavailable server.
D) Collect performance statistics from other WebSphere MQ based applications and extrapolatethe findings to your requirements.

4. An application is experiencing issues when processing large volumes of nonpersistent messages.
Which of the following is a likely cause of the issue?

A) The WebSphere MQ linear logs are not large enough to handle all of the transactions.
B) The WebSphere MQ circular logs are not large enough to handle all of the transactions.
C) The application is processing in syncpoint, and has not performed a commit recently.
D) The BATCHSIZE parameter on the queuemanager was left at the default setting.

5. A bus company is implementing a solution which will display in real-time all bus positions on a central dashboard. Each bus is transmitting position information at regular intervals. What is the best way of implementing this solution given that there is limited bandwidth for communication?

A) Each bus updates a message in a common queue and the dashboard application reads thewhole queue every few minutes.
B) Each bus sends a message to a central queue which is read by the dashboard application
C) Each bus sends messages to a separate queue and the dashboard application checks thosequeues every few minutes.
D) Each bus updates a message in a central queue using its number as a key and the dashboardapplication reads the whole queue every few minutes.
