QUESTION NO: 1
The advantage of core tiles is that they allow you an opportunity to examine the cause of
problems, so that they can be resolved.
However, core files must be managed because they_____.

A. take up large amounts of disk space
B. make numerous entries into the /var/adm/wtmpx file
C. steal resources from the processor, slowing down system performance
D. fill up swap space; this will begin to slow the system due to swaps
E. fill up swap space; this will begin to slow the system due to paging

Answer: A

Explanation: Part of the job of cleaning up heavily loaded file systems involves locating and removing files that have not been used recently. You can locate unused files by using the ls or find commands.
Other ways to conserve disk space include emptying temporary directories such as the directories located in /var/tmp or /var/spool, and deleting core and crash dump files.
Note: Core files are generated when a process or application terminates abnormally. Core files are managed with the coreadm command.
For example, you can use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier to track problems byexamining the core files in a specific directory whenever a process or daemon terminates abnormally.

Answer: D

Explanation: How to Disable Programs From Using Executable Stacks

set noexec_user_stack=1
Reboot the system.
# reboot

QUESTION NO: 1
Given:
class Overloading {
int x(double d) {
System.out.println(“one”);
return 0;
}
String x(double d) {
System.out.println(“two”);
return null;
}
double x(double d) {
System.out.println(“three”);

}
public static void main(String[] args) {
new Overloading().x(4.0)
}
}
What is the result?

A. One
B. Two
C. Three
D. Compilation fails

Answer: D

Explanation: overloading of the x method fails as the input argument in all three cases are
double.
To use overloading of methods the argument types must be different.
Note: The Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures. This means that methods within a class can have the same name if they have different parameter lists

QUESTION NO: 1
Object Security controls access to Subject Areas, Tables, and Columns in OBIEE and can be implemented by using which method?

A. Single Sign-On (SSO)
B. Database Authentication
C. Business Logic Object Security
D. External Table Authentication
E. LDAP Authentication

Answer: C

Explanation: Object-level security controls the visibility to business logical objects based on a user’s role. You can set up object-level security for metadata repository objects, such as subject areas and presentation folders, and for Web objects, such as dashboards and dashboard pages, which are defined in the Presentation Catalog.
1) Business logic object
This controls access to objects, such as:
* subject areas
* presentation tables
* presentation columns
For example, users in a particular department can view only the subject areas that belong to their department.
2) Web object security
This provides security for objects stored in the Web Catalog, such as dashboards, dashboard pages, folders, and reports. You can view only the objects for which you are authorized. For example, a mid-level manager may not be granted access to a dashboard containing summary information for an entire department.

QUESTION NO: 2
Which two steps are needed to set up Failover support for an OBIEE deployment?

A. Use Installer to affect Horizontal scale out of an existing instance
B. Employ WebLogic Enterprise Edition, licensed separately
C. Use Installer to set up separate single instances, then apply Horizontal scale out clustering
D. Apply OBIEE Clustering option
E. Leverage spare hardware capacity of single machine by using Verticalscale out option

Answer: A,D

Explanation: Horizonal Scaleout of System Components
* Used for adding additional managed servers (Java components) and
system components to an existing cluster
* Used for scalability and failover
* Set up via the Universal Installer > Scale Out BI System option

QUESTION NO: 3

QUESTION NO: 1
When do you specify the type of interleaving for a grid disk?

A. When you create the cell disk
B. When you create the grid disk
C. Through ASM
D. When you create a tablespace

Answer: C

Explanation: Automatic Storage Management (ASM) is the storage management foundation of Exadata. ASM virtualizes the storage resources and provides the advanced volume management and file system capabilities of Exadata. Striping database files evenly across the available Exadata cells and disks results in uniform I/O load across all the storage hardware. The ability of ASM to perform non-intrusive resource allocation, and reallocation, is a key enabler of the shared grid storage capabilities of Exadata environments. And the ASM mirroring and failure group functionality provides much of the data protection and resiliency across the Exadata environment.
With ASM, data is mirrored across cells to ensure high availability in the event of cell failure.

http://www.pythian.com/news/17905/physical-disk-cell-disk-grid-disk-and-asm-disk-in-exadata/

QUESTION NO: 2
Why would you reduce the default disk_repair_time parameter?

A. To extend the availability of your ASM disk groups.
B. To reduce the need for high redundancy
C. To reduce the amount of data collected for a fast resynch
D. To increase performance of an Exadata Storage Server.
