Let’s get going!
Here are the interview questions on SSIS often asked freshers or individuals with 5 or 3 years of experience.
Ans: SSIS, or SQL Server Integration Services, is a component of Microsoft SQL Server. It can be used to accomplish a wide range of data migration tasks. It is an ETL tool mainly used to handle data extraction, transformation, and load operations. It can handle other tasks besides ETL, like data profiling, file system manipulation, etc. Many batch operations can be performed in SSIS using VB.Net or C#.Net languages.
Note that this is one of the most commonly asked SSIS interview questions.
Ans: Important SSIS components of the package are listed below:
Ans: Through the control flow option, you can logically and graphically link the tasks and program them graphically. The three logical connectors used in SSIS are success, failure, and complete. By using FX (expression), you can handle more complex control flow conditions. These are some basic SSIS interview questions.

Sequence Containers: They are used to group similar tasks. Sequence containers are like organization containers used for complex SSIS packages.
The loop containers are used to execute any task several times; if you want to update the records ten or more 10 times, you can use “for” loop containers. Here, the user need not create ten packages to execute or complete the task, nor must you run the whole package ten times while scheduling the job.
If you don’t know the number of times the task will be executed, you can use it for each loop container. If you want to delete all files from any particular folder and you don’t know the number of files that are contained in the folder, then by using each loop, you can select the files and delete them at once; in this container, you will be informed when all of the files will be deleted. This is an essential answer to one of these SSIS interview questions
Ans- When development packages are converted to executable packages, it is known as deployment. SSIS packages can be directly deployed by right-clicking the projects of integration services and building them.

Ans: The SSIS connection manager has issues in storing the password. Hence we can follow the below-proposed solutions:
Method 1: Create and use SQL Server Agent Proxy account which uses credentials that makes SQL Server Agent capable of the running job as an account having required permissions to run the job or as the account which created the package.
This method is used for decrypting secrets and key requirements of the user are satisfied.
There are chances that this method could fail because the secrets are decrypted by taking the current user and current computer information which will inadvertently fail if the project or package is moved to a different computer.
Method 2: Set the value of Package Protection Level Property to Server Storage. This stores packages on the SQL Server and lets users access this through SQL Server database roles.
Method 3: Set the value of Package Protection Level property as “Encrypt Sensitive with Password”. The method uses a password for encrypting sensitive information. This can be added to the SQL Server Agent job to run the job effectively.
Method 4: Package configuration can be used to save sensitive information which can later be stored in a secured folder. When the package is run, the information is obtained from this config file. If we do not want to save the secrets in the package, we can set the property of Protection Level to “DontSaveSensitive”.
Method 5: Package templates having a good protection level can be created for long-term solutions.This is an important answer to these kinds of SSIS interview questions for 9 years experience.
Ans: MSBI is known as Microsoft Business Intelligence is a powerful tool that provides solutions for Business Intelligence and Data Mining Queries.
