Session Takeaway • Review on important point of exam

objectives• Tips, trick, and experiences• Exam 70-432• Discussion

• Not goals:– To cover all exam objectives– Exam cram– Cheating on exam

Skills measured (70-432)• Installing and Configuration (10 %)• Maintaining SQL Server Instances (13 %)• Security (15 %)• Database Maintenance (16 %) • Data Management Tasks (14 %)• Monitoring and Troubleshooting (13 %)• Optimizing Performance (10 %)• High Availability (9 %)

70-432 at a glance• It’s a basic SQL Server exam• Pre requisites for the higher level (IT Pro)

exams• Emphasize on daily administrative tasks:

install, configure, backup/restore, server monitoring

• It won’t test the scripting/code, but you need to know them at the higher level

• 50-60 MCQ questions

How to prepare…• Get your hand dirty, try it…..– Download Virtual PC 2007– Install Windows Server 2003/2008– Install SQL Server 2008– Try all exercises from your book– Don’t just read, try!

Security• Which port number required by SQL

Server• Differences between:– Login Vs User– Server role and database role– Types of role and their permission• Securityadmin, sysadmin, dbcreator, etc

• Always assign user to most restrictive role

Security (2)

• Windows Integrated VS Mixed Auth• When to use SQL auth instead of Windows• Assigning permission to:– Database > Schema > db objects (table,

column, sp, view, etc)

• Understand cross database ownership chain

• Types of assignment:– Grant, with grant, revoke, deny

Security (3)• Configuring server with sp_configure• Instance level configuration• Important option:– Show advanced option– Enable distributed queries– Enable cross ownership chain

Security (4)• Transparent data encryption• What is it?• How to configure…• Advantages….

Performance (1)• Understand different types of

indexes:– Clustered– Non clustered– Both of them can be unique/non unique

• Generic guideline:– Clustered: reading, sorting, grouping– Non clustered: insert, update, delete

Performance (2)Index maintenance:– Reorganize– Rebuild– Drop – recreate

• With online option• Using maintenance plan wizard and

SQL agent job

Performance (3)• Understand file group and db file

setting– Filegroup– File sizing and placement (mdf, ldf, ndf)

• Partition– Advantages– How to setup:• Partition function• Partition scheme• Apply scheme to table

Backup/Restore

• Differences between backup types, and when to use each of them:• Full• Differential• Transaction log

• Impact of different database recovery mode:• Simple, bulk logged, full• What kind of features depends on FULL

recovery mode?

Backup/Restore(2)

• Important WITH option in backup:– INIT/ NOINIT– COMPRESSION/ NO_COMPRESSION– COPY_ONLY >> do backup without breaking

backup sequence

• Backup log special option:– NO_RECOVERY >> backup tail when db is

online– NO_TRUNCATE >> if db is damage

Restore(3)• Important restore option:– NO_RECOVERY/ RECOVERY– STOP AT……–MOVE….– REPLACE…..

Backup/Restore(3)• Steps to recover db in disaster:

1. Always backup tail log first!2. Restore latest full backup3. Restore latest differential backup (if

any)4. Restore any necessary log backup

(since last diff backup)5. Restore the tail log backup6. Use STOP AT… if required

QUIZ 1• Current backup config:– Full backup every Sunday at 01:30 am– Differential: weekdays at 01:00 am– Log backup: weekdays at

– 11 am– 5 pm– 11 pm

• The DB is crashed on Thursday, at 2:15 am. There are many ongoing transaction. How to restore?

Automation/monitoring• Understand important role of SQL

Agent– Services– Services account

• How to create SQL Agent job/ schedule

• Create alert/notification and operator

Automation/Monitoring• Monitoring with Dynamic

Management View (DMV)• Special views for

monitoring/retrieving server and database metadata

• Useful DMVs:– Sys.dm_exec_query_stats– sys.dm_exec_trans_lock– Sys.dm_exec_index_usage

Useful Resources• Technet SQL Server Virtual Labs• ExamNotes.com certification forum• MS Press book: 70-432 Self Study
