1Z0-865 Assignment not pass and needs to resubmit

[Hong Gao]

Hi guys,

Unfortunately, my 1z0 - 865 assignment failed, and I need to resubmit within one month.
Below are part of my missing points for 3 diagrams, and can you please provide some insights for me to revise and resubmit. I don't have much hands on experience in this space

Class Diagram:
(*) Missing presentation, business, and integration tiers components referenced in other diagrams
Questions: How to make presentation, business and integration ties components in class diagram, and then referenced in sequence diagram as example

Deployment Diagram:
(*) Missing platform profile details such as web/app server, OS, RDBMS, etc.
(*) Missing deployment of components/ear/war/ejb-jar.
Questions: Is it enough for me to add notion that web/app server is WebSphere Application Server 8.5 with IBM 3/390. RDBMS is oracle 11g? how to add components/ear/war/ejb-jar on deployment diagram?

Interaction Diagram( Sequence diagram)
(*) Missing actor/actor name from sequences
(*) More detail required for Use Cases and methods invocations (too high level)
Questions:In the guide book, there is classic interaction diagram actors consisting of user>browser>http server>JEE server>JEE JDBC>oracle database, is this always the case, what is the variant? and how to add methods invocations in sequence diagram?

Many thanks,

Hong

All classes mentioned in the class diagram should be in the sequence diagram.

As you move from tier to tier, the sequence diagram should be clear showing such and such method invocation is from the business tier or integration tier as you move down the tiers to get data from DB

Platform profiles shouldn't be a must but it does give the examiner a good indication the hardware (CPU, RAM. storage etc) the server is using.

Mentioning what app server or DBMS is not that important. However mentioning clustering, load balancing, security are important.

Saying whether you are using single server to serve presentation and business tiers vs separate machines/server is important. Because such decision affect scalability and availability etc

"Too high level" indeed is a problem. Having too little classes or too general class to represent something gives an impression that that object/class is a black box to examiner.
