You need to generate a report on all of the Exchange Server 2007 computers in your Exchange organization. The report must include:
– Operating system versionNumber of processors
– Total physical memory
– Number of storage groups
– Number of mailbox databases
What should you do?
A. Run the Get-ExchangeServer | Format-List cmdlet.
B. Run the Get-OrganizationConfig cmdlet.
C. Run the Test-SystemHealth cmdlet.
D. Run the Health Check scan in the Exchange Best Practices Analyzer.
An administrator is attempting to recover corrupted data from a four disk RAID group. However, the administrator does not know which RAID level was used. When investigating the volumes, the administrator notes that there is a duplicate of all data on two of the disks. Which of the following RAID levels was in use?
A. RAID 0
B. RAID 5
C. RAID 6
D. RAID 10
What determines which bits in an IP address represent the subnet, and which represent the host?
What can you do with the DBMS_LOB package?
A. Use the DBMS_LOB.WRITE procedure to write data to a BFILE.
B. Use the DBMS_LOB.BFILENAME function to locate an external BFILE.
C. Use the DBMS_LOB.FILEEXISTS function to find the location of a BFILE.
D. Use the DBMS_LOB.FILECLOSE procedure to close the file being accessed.
Examine the parameters for your database instance:
————————– ——————————- —————————
undo_management string AUTO
undo_retentioninteger 12 00
undo_tablespace string UNDOTBS1
You execute the following command:
SQL> ALTER TABLESPACE undotbs1 RETENTION NOGUARANTEE;
Which statement is true in this scenario?
A. Undo data is written to flashback logs after 1200 seconds.
B. Inactive undo data is retained for 1200 seconds even if subsequent transactions fail due to lack of space in the undo tablespace.
C. You can perform a Flashback Database operation only within the duration of 1200 seconds.
D. An attempt is made to keep inactive undo for 1200 seconds but transactions may overwrite the undo before that time has elapsed.
You need to create a table for a banking application. One of the columns in the table has the following requirements:
1) You want a column in the table to store the duration of the credit period.
2) The data in the column should be stored in a format such that it can be easily added and subtracted with date data type without using conversion functions.
3) The maximum period of the credit provision in the application is 30 days.
4) The interest has to be calculated for the number of days an individual has taken a credit for.
Which data type would you use for such a column in the table?
D. INTERVAL DAY TO SECOND
E. INTERVAL YEAR TO MONTH
You notice that the performance of your production 24/7 Oracle database significantly degraded. Sometimes you are not able to connect to the instance because it hangs. You do not want to restart the database instance.
How can you detect the cause of the degraded performance?
A. Enable Memory Access Mode, which reads performance data from SGA.
B. Use emergency monitoring to fetch data directly from SGA analysis.
C. Run Automatic Database Diagnostic Monitor (ADDM) to fetch information from the latest Automatic
Workload Repository (AWR) snapshots.
D. Use Active Session History (ASH) data and hang analysis in regular performance monitoring.
E. Run ADDM in diagnostic mode.
*In most cases, ADDM output should be the first place that a DBA looks when notified of a performance problem.
*Performance degradation of the database occurs when your database was performing optimally in the past, such as 6 months ago, but has gradually degraded to a point where it becomes noticeable to the users. The Automatic Workload Repository (AWR) Compare Periods report enables you to compare database performance between two periods of time.
While an AWR report shows AWR data between two snapshots (or two points in time), the AWR Compare Periods report shows the difference between two periods (or two AWR reports with a total of four snapshots). Using the AWR Compare Periods report helps you to identify detailed performance attributes and configuration settings that differ between two time periods.

Which two statements correctly describe the relation between a data file and the logical database structures? (Choose two.)
A. An extent cannot spread across data files.
B. A segment cannot spread across data files.
C. A data file can belong to only one tablespace.
D. A data file can have only one segment created in it.
E. A data block can spread across multiple data files as it can consist of multiple operating system (OS)
Which two statements below could explain why the vSphere Client is reporting N/A for hyperthreading? (Choose two.)
A. The physical CPUs in the host do not support hyperthreading.
B. Hyperthreading is disabled in the host’s BIOS.
C. The physical CPUs in the host are not multi-core.
D. The number of CPUs meets or exceeds the maximum without hyperthreading.
The VMware vCenter Server Appliance has been deployed using default settings.
What user name and password are used to log in to the administration interface to configure the appliance?
A. The initial user name and password must be supplied on the first login attempt.
B. The initial user name and password must be supplied during deployment.
C. The initial user name is root and the password is blank.
D. The initial user name is root and the password is vmware.
A user has a perimeter firewall and up-to-date antivirus software. The user is asking what else they can do to improve their security. Which of the following will have the MOST impact on network security? (Select TWO).
A. Install additional antivirus software
B. Disable screen savers
C. Conduct a daily security audit
D. Assign security rights based on job roles
E. Use strong passwords
To improve security, assign security rights based on job roles. You need to give least amount of privilege to users so that they can do their jobs without having access to resources that have nothing to do with their job roles.
Small form factor PCs that utilize full-height PCI and PCI-Express cards need which of the following supplementary items to allow for proper installation?
A. FireWire cards
B. Riser cards
C. Storage cards
D. Network cards
