B. ensure that there is a clustered index on the results column
experiments table.

3). Database includes a job_cost table that typically holds 100000 rows but can grow or shrink by as much as 75000 rows at a time. the job_cost table is maintained by a batch job that runs at night.
during the day, the job_cost table is frequently joined to other tables by many different queries. Users report that their initial queries are very slow, but then response time improves for subsequent queries.
How should you improve the response time of the initial queries?
A. run the sp_updatestats stored procedure as part of the nightly batch
job.

4).you are the DBA. You receive reports that your sales application has very poor response times.
The database includes a table that is defined as follow:
create table dbo.orders {
OrderID int identity(1,1) NOT NULL,
SalespersonID int NOT NULL,
RegionID int NOT NULL,
Orderdate datetime NOT NULL,
Orderamount int NOT NULL,
CustomerID int NULL}
the orderid column is the primary key of the table. there are also indexes on the regionid and orderamount columns.
you decide to run a showplan on all queries in the application. The following query, which accesses this table is used to list total average sales by region:
select t1.regionid,avg(t1.salestotal) as regionaverage
from (select regionid,salespersonid,sum(orderamount) as
salestotal
from orders
group by regionid,salespersonid as t1
group by t1.regionid
you set the SHOWPLAN_TEXT option to ON execute the query.the
showplan output is as follows:
...
you suspect that this query is part of the problem because the showplan indicates that the query is performing a table scan operation.
what is the most likely reason that this query is performing a table scan?
A. there is no composite index on OrderID,RegionID,and Orderamount.
B. there is no where clause in the query.
C. the query contains a subquery.
D. the query is performing aggregate operations.

C. Create a rule and bind the rule to the Beginning_effective_date
column.
D. Create INSERT and UPDATE triggers on the policy table that compare
the values.

What should you do to?
A. Create a clustered index on the demographic table over the most
accessed columns.

37)You must reconcile the checking account for your company. You have a CheckRegister table, an InvalidCheck table, and a ClearedCheck table. The ClearedCheck table lists checks that have cleared the bank.
You must update the ClearedDate column of the CheckRegister table for
any checks that are on the ClearedCheck table. If the check is in the ClearedCheck table but not on the CheckRegister table, you must insert a row into the InvalidCheck table. If the amount shown for a check in the ClearedCheck table is different from the amount shown for the same check in the CheckRegister table, you must insert a row into the InvalidCheck table. Each row must be deleted from the ClearedCheck table after it has been evaluated for accuracy.
Which statement group should you use to accomplish this task in the shortest time?
A. ...
B. ...
C. UPDATE CheckRegister SET CheckRegister.ClearedDate = ClearedCheck.ClearedDate
FROM CheckRegister
JOIN ClearedCheck ON CheckRegister.CheckNumber = clearedCheck.CheckNumber
