A solution designer is considering different API options for a new WebSphere MQ application.

• B.JMS
• C.WebSphere MQ classes for .NET

A manufacturing company is looking to provide its customers an online version of its order maintenance application. Customers will be able to check status, update the order, or delete the order. The existing solution is currently WebSphere MQ based, and the online interface will have strict performance requirements. If the customer updates or deletes an order, the message cannot be lost. Which one of the following solutions will BEST meet the requirements stated?

• A.Alter the channel to set NPMSPEED(FAST), and send the messages down multiple channels.
• B.Design the query and modify operations to use nonpersistent and persistent messages respectively, and utilize two phase commit only where Necessary
• C.Port the existing application to z/OS which has the highest performance and availability qualities of service
• D.Ensure the queue data and logs are located together on the fastest disk possible

A bus company is implementing a solution which will display in real-time the arrival information of the next bus on the bus stop sign. Each bus is sending information about its position at regular intervals. What is the best way of implementing this solution given that there is limited bandwidth for communication? The bus stop sign:

• A.subscribes to messages published by the bus
• B.sends a message with a request every few minutes to a central system in order to query busposition. All replies are compressed.
• C.queries a central system for bus position using SOAP over HTTP
• D.replicates its own database every few minutes with a database stored on a central system

Which of the following should generally be avoided if an application is being designed for optimal efficiency?

• A.Code programs to open and close queues, or connect and disconnect from the queue manager only once, if the queues or connection will be used again.
• B.Group a batch of messages within a unit of work where appropriate, so that they can be committed all at once (e.g., get and put messages under syncpoint and commit them in groups of 10, rather than committing them individually).
• C.Make messages nonpersistent if they do not need to be recoverable.
• D.Bundle the data to be transmitted into as few messages as possible (e.g., rather than sending a hundred 1MB messages, send one 100MB message).
