In order to manage Java EE applications across domains, Oracle Enterprise Manager includes the ability to store Java EE applications (i.e. ear and war files) within the software library which can include multiple versions of these applications

for quick deployments to multiple domains across your enterprise or cloud simultaneously.

Note:

Organizations have to be agile in order to compete globally and adapt to changes in business and technology. To achieve this objective, many large IT organizations have implemented flexible integration solutions that include Java EE

application servers such as Oracle WebLogic Server and Fusion Middleware technologies.

Correct Answer: C

Once you have defined jobs, you can save these jobs to the Job Library. Use the Library as a repository for frequently used jobs. Analogous to active jobs, you can grant View or Full access to specific administrators.

In addition, you can use the Job Library to store:

Basic definitions of jobs then add targets and other custom settings before submitting the job

Jobs for your own reuse or to share with others. You can share jobs using views or giving full access to the jobs.

Incorrect:

Not A: New in Oracle Reports 11g Release 2 (11.1.2) is the database-based shared job repository, which provides the ability to display a consolidated view of job queues using Oracle Enterprise Manager

Correct Answer: D

You can use the nfsagentinstall script to install Oracle Management Agents (Management Agent) with the help of a central, shared Oracle home of an existing Management Agent.

Note:

If you want to install additional Management Agents on hosts that share a mounted drive where a Management Agent is already installed, then the best option is to use the software binaries of the shared Oracle home from the mounted drive

and configure the remote hosts to be managed by that Management Agent, thus capitalizing on the NFS visibility and saving hard disk space on the remote hosts. You can achieve this in GUI as well as in silent mode.

While the Shared Agent Deployment Wizard helps you install such Management Agents in GUI mode, the nfsagentinstall script helps you install in silent mode.

Much like the Shared Agent Deployment Wizard, the nfsagentinstall uses the software binaries from the shared Oracle home, and configures an EMSTATE directory on each of the remote destination hosts for storing configuration files such

as emd.properties, targets.xml, log files, and so on. Reference: Installing Oracle Management Agent Using Shared Oracle Home Using nfsagentinstall Script

Correct Answer: ACD

Oracle Enterprise Manager Ops Center 12c manages the lifecycle of Oracle Solaris Containers and Oracle VM Server for both X86 and SPARC.

Correct Answer: A

*

A compliance framework maps to a set of compliance standards that perform a collection of checks following broadly accepted best practices to ensure that IT infrastructure, applications, business services and processes are organized, configured, managed, and monitored correctly.

*

A compliance standard refers to one or more compliance standard rules.

Note: A compliance framework can be used to represent a framework such as Control Objectives for Information and related Technology (COBIT) or Payment Card Industry (PCI). A compliance framework is an industry-specified best practices guideline that deals with the underlying IT infrastructure, applications, business services and processes, and how they are organized, managed, and monitored. Compliance frameworks are hierarchical to allow for direct representation of these industry frameworks.

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.

Correct Answer: ABDE

A:

*

Configuration Management tailored for challenges in Cloud environment Challenge: Virtual server sprawl Feature: Inventory tracking, ongoing discovery

*

Drive asset utilization up by up to 70%. Eliminate Virtual Machine (VM) sprawl. Cut configuration management effort by 90%. Reduce provisioning effort by 75%.

Oracle Enterprise Manager provides an integrated and cost-effective solution for complete physical and virtual server lifecycle management.

B: Configuration Management tailored for challenges in Cloud environment Challenge: Dynamic topology changes (owing to elasticity) Feature: Topology mapping, dependency tracking

D: Oracle Enterprise Manager Compliance Management solution provides out-of-the-box compliance frameworks (for example, PCI and CIS) and compliance standards to map to Compliance Standard rules. This mapping enables you to visualize how noncompliant settings and actions will affect any compliance framework that an organization follows.

E:

*

Configuration Management tailored for challenges in Cloud environment Challenge: Drifts from pre- defined Service Feature: Configuration Baseline, Drift Tracking Topology mapping, dependencyConfiguration Baselines, ventory tracking, Drift

*

Oracle Enterprise Manager Configuration Management eliminates manual and time-consuming task related to Discovery, Deployment of Management agents, Inventory Tracking, Configuration Drift, Detailed Configuration Search and Compliance Management for reporting and management of industry and regulatory compliance standards.

Correct Answer: BCD

C: The Consolidation Planner feature enables you to match managed servers you want to consolidate with the generic physical machines, Oracle Exadata database machines, or Oracle Virtual Machine (VM) servers they can be consolidated to.

B, D:

/ The goal of consolidation is to identify such under-utilized servers and find a way to consolidate them, enabling the enterprise to free up as many servers as possible while continuing to maintain service levels.

Note:

/ Compare the consolidation scenarios you create to determine which consolidation strategy best meets your requirements.

Your objective is to:

*

Match source server resource requirements with destination servers best able to meet those requirements

*

Fit source server requirements with each destination server's available resources as tightly as possible, so you can get maximum usage of destination server capacity

*

Optionally balance the source server workload across all available destination servers Reference: Oracle Enterprise Manager Cloud Administration Guide , Using Consolidation Planner
