• Question 31:

  Which statement is true about the Oracle Enterprise Manager JVM diagnostics capability?

  A. JVM diagnostics can correlate a JVM thread with a database session as well as the SQL.

  B. JVM diagnostics can correlate a JVM thread with a database session but not the SQL.

  C. JVM diagnostics can correlate a JVM thread with SQL but not the database session.

  D. You use the Oracle Enterprise manager Java Explorer, not JVM diagnostics, to correlate a JVM thread with a database session as well as the SQL.

  Correct Answer: B

  *

  JVM Diagnostics provides immediate visibility into the Java stack. You can monitor thread states and Java method/line numbers in real time and you can proactively identify issues rather than diagnosing issues like application crashes, memory leaks, and application hangs after they occur.

  *

  JVM Diagnostics facilitates tracing of Java requests to the associated database sessions and vice-versa enabling rapid resolution of problems that span different tiers. It highlights the slowest SQL queries and helps administrators to tune SQL and the database to improve the performance application.

• Question 33:

  You need a workflow of tasks that must be performed for a particular lifecycle management activity.

  What Oracle Enterprise management functionality can you use to provide this?

  A. Deployment Procedures

  B. Connector Framework

  C. Configuration Control

  D. Diagnostics Pack and Tuning Pack

  Correct Answer: A

  Enterprise Manager provides a framework for automating, orchestrating, and tracking tasks that can be run on multiple Oracle homes. You can perform complex software life cycle management activities such as provisioning, patching, upgrade, and so on from the Cloud Control console. The workflow of all the tasks that need to be performed for a particular life cycle management activity is encapsulated in a Procedure. A Procedure is a hierarchal sequence of provisioning steps, where each step may contain a sequence of other steps. It provides a framework where specific applications and procedures can be built.

• Question 35:

  How is Service Availability defined in Oracle Enterprise Manager?

  A. Based on System and Service Test

  B. Based on Service Status

  C. Based on Service and System Status

  D. Based on System Test and Service Status

  Correct Answer: A

  Setting up the availability definition for the service. This can be service test-based or system- based. If you select service test, the service's availability is based on the execution of the service test by the one or more key beacons. If availability is based on system, availability is based on the status of one or more key components of the system.

• Question 36:

  The shared file system loader configuration on the Oracle Enterprise management Service is for ____________.

  A. Auditing

  B. Security

  C. High availability

  D. High availability and security

  Correct Answer: C

  The Management Service for Grid Control has a high availability feature called the Shared Filesystem Loader. In the Shared Filesystem Loader, management data files received from Management Agents are stored temporarily on a common

  shared location called the shared receive directory. All Management Services are configured to use the same storage location for the shared receive directory. The Management Services coordinate internally and distribute among themselves

  the workload of uploading files into the Management Repository. Should a Management Service go down, its workload is taken up by surviving Management Services. You must choose a shared receive directory that is accessible by all the

  Management Services using redundant file storage.

  Note:

  Oracle strongly recommends you to configure a shared file system loader so that a common location is maintained to store all the metric data files uploaded by the Management Agents.

• Question 37:

  Identify the application that is used to build and package applications as a set and that enables deployment by Oracle Enterprise manager.

  A. Oracle Virtual Application Builder

  B. Oracle Virtual Assembly Builder

  C. Oracle Application Jesting Suite

  D. Oracle Real Application Testing

  E. Oracle Package Builder

  Correct Answer: B

  Oracle Virtual Assembly Builder makes it possible for administrators to quickly configure and provision entire multi-tier application topologies onto virtualized and cloud environments. It provides a framework for capturing the configuration of existing software components and packaging them as self-contained building blocks known as appliances. These appliances can then be easily connected to form application blueprints known as assemblies. This innovative approach makes it practical for complex enterprise applications to easily be customized and provisioned in their entirety with minimal to no manual intervention onto virtualized and cloud environments.

• Question 38:

  What feature of the Diagnostic Pack for Oracle Database collects statistics on all active sessions and stores it in memory?

  A. Active Session History (ASH)

  B. Automatic Database Diagnostic Monitor (ADDM)

  C. Automatic Workload Repository (AWR)

  D. Automatic Storage Management (ASM)

  Correct Answer: A

  Oracle introduced Active Session History (ASH) in Oracle Database 10g. ASH automatically collects session related wait information via the Oracle database kernel (thus reducing the impacts of the collection of this information). The information is first captured into a memory buffer that is of a fixed size and is allocated from the SGA fixed area when the database is started.

• Question 39:

  What is the primary purpose of the Middleware Diagnostics Advisor (MDA) that is included in Oracle Enterprise Manager WebLogic Server management Pack Enterprise Edition/

  A. To provide configuration data reports and best practices.

  B. To provide root cause analysis and recommendations based on performance metrics and configuration data of the stack (WLS, JVM, application, database, and hosts)

  C. To correlate JVM threads with the underlying database tier to provide across-tier rrot cause analysis and to generate reports showing database usage related to the JVM

  D. To alert on Java memory leaks in WenLogic Server

  Correct Answer: B

  The Middleware Diagnostics Advisor analyzes the entire stack and provides diagnostic findings by identifying the root cause of a problem. It correlates and analyzes the input and offers advice on how to resolve the problem. Reference: Managing Middleware Targets

• Question 40:

  Identify the sequence of steps that is needed to set up the virtualization infrastructure before you start monitoring and managing virtualization targets with Oracle Enterprise manager.

  A. Register OVM Manager and discover Oracle VM Server; set up the storage infrastructure; configure networks and VLAN groups; and create a virtual server pool.

  B. Register OVM manager and discover Oracle VM Server; configure networks and VLAN groups; set up the storage infrastructure; and create a zone.

  C. Configure networks and VLAN groups; create a virtual server pool; register OVM manager and discover Oracle VM Server; and set up the storage infrastructure.

  D. Configure the networks and VLAN group; set up the storage infrastructure; create a virtual server pool; and register OVM Manager and discover Oracle VM Server.

  Correct Answer: B

  *

  The Oracle VM Manager provides the user interface that allows you to create and manage zones, virtual server pools, virtual servers, and guest virtual machines. Before you use the Oracle VM Manager to manage virtualization targets in Enterprise Manager, you must register an existing installation of the Oracle VM Manager.

  *

  A virtual server is a generic term used to describe a physical box which has virtualization software (hypervisor) running on it. A new virtual server can be provisioned by installing the OVM Hypervisor on a bare metal box. Before you add a virtual server to a server pool, it must be discovered.

  Setting Up Networks

  . You can define a name or an alias for each logical network. When you have created your networks, you connect the physical network ports on Oracle VM Servers to the logical networks. Before you define the logical networks in Enterprise Manager, you have to review your physical network configuration that you intend to use, such as VLAN and subnet usage.
