• Question 3:

  What three items can Service Availability be based on With Oracle Enterprise Manager?

  A. TCP/IP ping
  B. Service Test
  C. Synthetic transaction
  D. Components of system
  E. Database latency
  B. Service Test
  C. Synthetic transaction
  D. Components of system

  ---

  B, D: 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.

  C: The synthetic transactions provide a direct means of measuring the real end user experience for the various business services. This way of modelling the business services through the execution of synthetic transition provides a consumer perspective of the service availability and performance.

• Question 4:

  Which two privilege delegation types are supported by Oracle Enterprise Manager?

  A. Sudo
  B. DBrun
  C. Powerbroker
  D. Privilege Manager
  E. Group Policy Manager
  F. Persona_create
  A. Sudo
  C. Powerbroker

  ---

  If you do not have access to either Oracle account or root account, then you can use SUDO or PowerBroker access to switch users to perform the tasks, this is called Privilege Delegation. Privilege Delegation is a framework that allows you to use either SUDO or PowerBroker to perform an activity with the privileges of another user (locked accounts).

• Question 5:

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

  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. Setting up an Oracle VM network involves: Generating MAC Addresses Creating and configuring VLAN Groups Creating Networks Reference: Setting Up Cloud for IaaS

• Question 6:

  Which two Oracle Enterprise Manager functionalities can reuse the application-Specific user session recordings from Oracle Enterprise Manager Real user Experience Insight (RUEI)?

  A. Application Testing Suite
  B. Application Replay
  C. Application Workload Generator
  D. Configuration Management
  E. Compliance Management
  B. Application Replay
  D. Configuration Management

  ---

  B: In order to capture Web application workloads, Application Replay uses Oracle Real User Experience Insight (RUEI).

  D: You can install the Configuration Change Console (included in the Configuration Management Pack) if you want real-time configuration change monitoring. Real-time configuration monitoring means continuous detection, validation, and alerting of any configuration change that could be authorized or unauthorized.

• Question 7:

  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
  A. Deployment Procedures

  ---

  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.
