This set of SQL Server Multiple Choice Questions & Answers (MCQs) focuses on “Integration Services – 1”.
1. SSMS provides different options to develop your SSIS package starting with ___________ wizard.
a) Import and Export
b) Copy and Import
c) Export and BulkInsert
d) None of the mentioned
View Answer
Explanation: With SSIS wizards, we can create a structure on how the data flow should happen and make a package and deploy it based on our needs to execute in any environment.
2. Point out the wrong statement.
a) Prior to SSIS, Data Transformation Services (DTS) in SQL Server 2000 performs the tasks with fewer features
b) SSIS is used to perform operations like loading the data based on the need, performing different transformations on the data like doing calculations
c) Business Intelligence Development Studio (BIDS) is a tool which can be used to develop only SSIS packages
d) All of the mentioned
View Answer
Explanation: BIDS is available with SQL Server as an interface that provides the developers to work on the workflow of the process that can be made step by step.
3. Which of the following is the best practice related to SSIS?
a) Plan for capacity by understanding resource utilization
b) SSIS is an in-memory pipeline, so ensure that all transformations occur in memory
c) Baseline source system extract speed
d) All of the mentioned
View Answer
Explanation: SQL Server Integration Services is designed to process large amounts of data row by row in memory with high speed. Because of this, it is important to understand resource utilization, i.e., the CPU, memory, I/O, and network utilization of your packages.
4. If SSIS is not able to drive close to 100% CPU load, this may be indicative of ____________
a) Software Contention
b) Application contention
c) Processor contention
d) None of the mentioned
View Answer
Explanation: In Application contention, SQL Server is taking on more processor resources, making them unavailable to SSIS.
5. Point out the wrong statement.
a) SSIS moves data as fast as your network is able to handle it
b) It is important to understand your network topology and ensure that the path between your source and target have both low latency and high throughput
c) Integration Services can be tuned beyond the speed of your source
d) All of the mentioned
View Answer
Explanation: You cannot transform data faster than you can read it in SSIS.
6. The key counters for Integration Services and SQL Server are _______________
a) Process Bytes
b) Public Bytes
c) Private Set
d) All of the mentioned
View Answer
Explanation: Process byte is the amount of memory currently in use by Integration Services. This memory cannot be shared with other processes.
7. _________ represents to total memory pressure on the system in SSIS.
a) Page sec
b) Page Reads
c) Memory reads
d) All of the mentioned
View Answer
Explanation: If page reads consistently goes above 500, the system is under memory pressure.
8. The following Network perfom counters can help you tune your topology?
a) Total Bandwidth
b) Current Bandwidth
c) Bandwidth bound
d) All of the mentioned
View Answer
Explanation: Current Bandwidth counter provides an estimate of current bandwidth.
9. What do you understand by design limitation in SSIS package?
a) Making use of parallelism
b) Not making use of parallelism
c) Package uses few single-threaded tasks
d) None of the mentioned
View Answer
Explanation: The design limitation of SSIS package is not making use of parallelism.
10. ___________ represents how many network transfers per second are occurring.
a) Network Bytes
b) Network Transfers
c) Memory reads
d) None of the mentioned
View Answer
Explanation: If Network Transfers/sec is approaching 40,000 IOPs, then get another NIC card and use teaming between the NIC cards.
