Q81.

Point out the correct statement.

If the network is your bottleneck, then a potential solution is to use a single NIC card per server

To overcome the limitations of drivers, you can try to start multiple connections to your data source

For 64-bit systems, at design time you may be loading 32-bit drivers; ensure that at run time you are using 32-bit drivers

None of the mentioned

Discuss

Answer: (b).To overcome the limitations of drivers, you can try to start multiple connections to your data source

Q82.

When you execute SQL statements within Integration Services, the following optimization can be made?

If Integration Services and SQL Server run on the different server, use the SQL Server destination instead of the OLE DB destination to improve performance

In SQL Server 2008 Integration Services, there is a new feature of the shared lookup cache

If you cannot use commit size 1, use the highest possible value of commit size to reduce the overhead of multiple-batch writing

All of the mentioned

Discuss

Answer: (b).In SQL Server 2008 Integration Services, there is a new feature of the shared lookup cache

Q83.

Which of the following steps should be carried out using data types in SSIS for efficient results?

Make data types as wide as possible so you will allocate more memory for your transformation

Do not perform excessive casting of data types

Do not watch precision issues when using the money, float, and decimal types

None of the mentioned

Discuss

Answer: (b).Do not perform excessive casting of data types

Q84.

Point out the wrong statement.

Heap inserts are typically slower than using a clustered index

Use partitions and partition SWITCH command; i.e., load a work table that contains a single partition and SWITCH it into the main table after you build the indexes and put the constraints on

Use the NOLOCK or TABLOCK hints to remove locking overhead

Use a commit size of <5000 to avoid lock escalation when inserting; note that in SQL Server 2008 you can now enable/disable lock escalation at the object level, but use this wisely

Discuss

Answer: (a).Heap inserts are typically slower than using a clustered index
