Microsoft 70-175: Designing and Implementing Distributed Applications with MS Visual Basic 6.0
#1. You are developing an n-tier application that has five layers. The layers are user interface (UI), database, object server, business object, and database manager. You want the UI layer to reflect the security that is being used in the other layers by locking and disabling controls as appropriate. Which layer in the logical design provides security information to the UI?
#2. The address table in a database contains the following columns. AddresslD StreetNumber StreetName City Country CreatedBy CreatedDate Timestamp Which three columns would most likely be properties of an address business object? (Choose three.)
#3. You are developing an n-tier application that has four layers. The layers are user interface(UI) ,business objects, data objects, and database. You want to pass data from the database to controls on a Ul form. What should you do?
#4. You are designing the properties, methods, and events for components in a new VB application. There is a requirement that a customer have an ID number. How should you design the ID number?
#5. You are installing Microsoft Transaction Server(MTS) .The server will be used for supporting database transactions across multiple servers. Which component must you install accomplish this?
#6. You are establishing the environment for source-code version control of a new Visual Basic application. You are using Microsoft Visual SourceSafe 6.0. You want to store only code that can be complied. What should the developers do to ensure that code in the source?
#7. You are planning a new distributed application. The customer requires a thin-client application. The application must be able to run on multiple platforms. You want to ensure that the application requires as little client installation as possible and requires little or no reinstallation when the application is upgraded. Which server component must you install?
#8. You create an event for your control. The event will expose the OnBeforeDelete method to the container. Giving the container the option to cancel the deletion if the container does not handle the event. The deletion should continue.the event declaration is shown in the following line of code Event onBefore Delete (bContinue As Boolean)
#9. You implement a UserDocument that will be used in a variety of active document containers. Your UserDocument must determine the name of the default COM interface for the container. Which code fragment must you use to retrieve the name?
#10. You implement a COM EXE server. You want each component hosted by this server to execute in its own thread. Which threading Model option must you use?
