Question: Why MSCRM? Since so many CRM available in the market like ERP, SAP, SIEBEL etc But How MSCRM is different from others?

Answer: World-class customer experiences begin with your people. By giving your people the right tools to multiply their productivity, multiply their impact, they can drive your organization to achieve your goals, multiply your revenue, and multiply your customers.

The top reasons, why organizations choose Microsoft Dynamics CRM instead of other CRM to create world-class customer:

Ease of Use :

Since MSCRM is a Microsoft product which is very similar & integrated with other Microsoft Products Like MS Word, MS Excel, MS Outlook, MS SharePoint, Internet Explorer etc, so it is very familiar to all those businessmen who use to spend 70% of his time on these tools, To understand this CRM no additional tool need to learn, no additional software needs to be install. Anyone could easily learn MSCRM with little training.
In other words, we can also say that

it integrates with Microsoft Business Solutions for Financial Management, Microsoft Office, and other systems that you get a complete picture of your customer.

It's important to note just how easy it is to integrate Microsoft CRM with Microsoft Office. Because it is so easy it enables your employees to access Microsoft Dynamics CRM right from their Microsoft Office Outlook whether they are working online or offline. It's a great tool for your sales department and it takes little training to make it happen.

Dynamic :

Since MSCRM hide Dynamic word inside itself its abbreviate as 'Microsoft Dynamic CRM'. We can extend it at any level. Microsoft itself provides three modules (Sales, Marketing & Service). But anyone could add its own module. Apart from this MSCRM is easily integration with other MS Products as well as various third-party tool like Ava-ya etc.

Three Deployment Options :

MSCRM is the only CRM product available in the market who have 3 Deployment options, 

On-Premise, Online, and IFD (Internet Facing Deployment).

The Cloud :Microsoft invests over $2 billion US dollars in cloud infrastructure every year. Microsoft Dynamics CRM is one of the quickest and one of the easiest ways for your business to take advantage of the cloud and cloud economies, including helping to reduce systems management and maintenance costs as well as meaning you pay only for the capacity you need.

Value :When considering costs—including licensing, services, training, deployment, administration and maintenance — customers, media, and industry analysts regard Microsoft Dynamics CRM as one of the best value offerings in the industry.

Language Support :MSCRM is only product available in the market which is Available in more than 40 languages.

Access Clients :MSCRM is the only product in the market which could be accessible through Mobile, Outlook and Web client. MSCRM 2013 also accessible from Tablet also.

.Net Development Platform :

MSCRM use .net framework. All Plug-Ins, Custom WF has written in either C# or VB. Even the whole MSCRM Pages, forms has designed in .net(.aspx page). So it's easy for the .net developer to write code in MSCRM and make it understandable for itself.

Question: How can we restrict any 'Entity Field' from being shown in Advanced Find?
Answer: Using Searchable Property of attribute(Entity Field.

Did you know that you can set each attribute of each entity to be able to advanced find or not?

By doing this you can specify which fields the users can search on. That means that all the fields which you do not use in your CRM system can be removed from the list to make using the advanced find easier.

So how do you do this? Just:
- go to system
- customization
- customize entities
- select any entity
- go to the tab attributes
- select any attribute
- switch the flag 'Searchable'

Can we do the same using Field Security Profile?
The answer is NO, the difference is described below:

if user A is added to Field level profile where he is not able to read field A then when user A does the advanced find, system will display this column in advanced find but it will be blank column (meaning the user will not see/read the value and field level security will be applied).

Question: How can we restrict any 'Entity' from being shown in Advanced Find?

Answer; Using Security Role: 

Best way to achieve this applies security settings if you remove the read/view permission of unused entity in CRM security, then those entities will not available.

But if you have read privilege on the entity and still you want that entity not to be shown in Advanced find or If you want permanently hide entity from Advanced Find then there is no supported way.
But there is an unsupported way to achieve the same. CRM exposes below Boolean property in EntityMetadata to identify which entity should appear in Advanced Find.

EntityMetadata.IsValidForAdvancedFind Property - Gets or sets whether the entity is will be shown in Advanced Find.
AttributeMetadata.IsValidForAdvancedFind Property - Gets or sets the property that determines whether the attribute appears in Advanced Find.

Try below query to hide Account entity from Advanced Find.

update MetadataSchema.Entity set IsValidForAdvancedFind = 0 where Name = 'account'

update MetadataSchema.Relationship set IsValidForAdvancedFind = 0
where ReferencingEntityId = (select MetadataSchema.Entity.EntityId from MetadataSchema.Entity where Name = 'account')
and IsValidForAdvancedFind  = 1


Reset IIS and clear server(and client) cache.

This will hide the entity for all users on the Advanced Find.

Still Adding...

Note:

Apologies in advance for not providing answers of these question

I did that intentionally because I didn't want to explain the answer theoretically and in few lines only. 

I would like you to google the answers and read lot of articles about each topic/question and collect the information as much as you can (like I do, if I want to learn about any topic). This is the best way to prepare yourself  for the interview. This is my advise especially for those who didn't work much in Microsoft Dynamics CRM and have less practical exposure.

Today, Interviewer seems not interested to listen the scripted answers or theoretically definition. (Especially a Interviewer like me😄) They always expect the answers with practical or real time examples. That knowledge & confidence you will only get once you do the RnD and find stuff about each topic yourself.

Nevertheless, I did write few articles to provide answers of few interview questions, however, due to lack of time I couldn't provide for all. I am still working on it though. 

Meanwhile, you can get in touch with me anytime if you find any trouble to find the answers.

Wish you all the very best and good luck....👍✌
