11. What is Sales and Marketing life cycle in MSCRM?
12. What is Queue entity in MSCRM?
13. What is 1:1, 1:N and N:N relationship in Microsoft Dynamics CRM?
14. How a Plug-in is different from a Call-out?
15. What is 'Append' and 'Append To' privilege in MSCRM? Give one example of it?

Ans: 'Append' and 'Append To' priviledges works together. 'Append To' priviledge will allow other entities to get attached with the entity. 'Append' priviledge will allow the entity to attach the records to the entity with 'Append To' privildege.

Let us understand this with simple example:
Let us say that you want to attach a note to a case then note entity should have 'Append' access right and case entity should have 'Append To' access right.

Let us take one more example to understand this. Suppose you have two custom entities called 'TestCustomEntity1' and 'TestCustomEntity2'. You want to attach the 'TestCustomeEntity2' records to 'TestCustomEntity1'records. For this you need to have 'Append' access right on 'TestCustomEntity1' entity and 'Append To' access right on 'TestCustomEntity2'.
Now guess will I be able to attach the records? Answer is "NO" because we need to create a 1:N relationship between 'TestCustomEntity1' and 'TestCustomEntity2'.
Now the user who has above mentioned access right in his security role will only be able to add 'TestCustomEntity2' records to 'TestCustomEntity1'.
16. How to create a Custom Entity record using SDK?
Ans: Using Dynamic Entity.
17. How to join two table using Query Expression?
Ans: Using Linked entity. You should always try to minimize the number of SWS calls that we make in the database. Often during code review it is explored that the number of Microsoft CRM web-service could have been reduced by making use of the Linked-entity concept. So we should always look for the opportunity to minimize the effort.
18. Can we modify the name of Root Business Unit?
Ans: No; We will have to re-install MSCRM.
19. Suppose if I have 20 user license and I have created 20users. What will happen if I create 21st User?
Ans: The 21st User will get created in MSCRM but that user will be in disabled state.
20. What are the maximum number of tabs allowed on a Microsoft Dynamics CRM 4.0 form?
Ans: 8
21. How to enable/disable the form assistant? How to make sure the form assitant is expanded/cllapsed on a form?
Ans: Navigate to Customization >> Open the Entity >> Open Forms and Views >> Open Form >> Select Form Properties >> Open Display Tab >> Check/Uncheck the "Enable the Form Assistant" and "Expanded by Default".

The interviewer will always try to figure-out whether one is comfortable with the basic concepts of Microsoft CRM (MS CRM) or not and after that; questions will be asked from your previous experience (if you have any experience in CRM). Those questions will be something like this:
1. What was you role in the MSCRM implementation project that you have worked on?
You should be honest while giving answer to this question and should give a brief overview of the project and your role. This is very important question because the answer of this question will tigger so many questions. You should highlight the key skills you have; this way you will divert the attention of the interviewer to your key skills and try not to expose the area in which you are less confident.
2. What was the most challenging task you have faced till now?
Here you should give answer that exihibit your positive attiude . e.g. for a techincal consultant it may be something like ... "I was new to the suppport and during this experience i faced challenging issue related to plug-in that impoved my debugging skills. Email-to-case plug-in was really diffcult as we had to take care of so many conditions. I have learnt one thing during my previos assignment and that is 'Never give-up'".
3. What was the size of the implementation? (i.e. the number of user-licenses)
