To accomplish the task in this scenario, you should create a delta threshold monitor. A delta threshold monitor is used to measure a change. For example, if you set the threshold limit to 2 GB and a time interval of 30 minutes, the delta threshold monitor will generate an alert if 2 GB of data is added or removed from the disk drive every 30 minutes. You can create a delta threshold monitor by navigating to Operations Console > Authoring > Management Pack Objects > Monitors > Create a new Monitor.
A delta threshold monitor is part of the single threshold monitors. A single threshold monitor can be used to define only one limit. If the performance counter goes above or below the threshold limit, an alert is generated or the state of the monitor changes. The following types of single threshold monitors are supported in Operations Manager 2007:
• Simple threshold monitor: This measures the value of a performance counter against the threshold limit specified by you. If the performance counter goes above or below the threshold limit, an alert is generated or the state of the monitor changes.
• Average threshold monitor: This measures the value of a performance object by comparing it with a defined fixed limit. The average threshold monitor takes the most recent number of samples and calculates the average value of these samples to check whether the threshold has been exceeded or not.
• Delta threshold monitor: This measures the change.
• Consecutive samples over threshold monitor: This generates alerts only if the performance counter exceeds the threshold a specific number of times in succession over a given period of time. This monitor is useful in preventing false alarms when there are sudden increases in a performance counter.
You should not create a Self-Tuning Threshold monitor to achieve the objective in this scenario. By using Self-Tuning Thresholds in Operations Manager 2007, you can monitor a computer's counter activities, such as processor utilization, thereby eliminating the need to manually configure thresholds for alerts. Operations Manager 2007 can be used to create and update a performance baseline, which represents normal activity for the counter.
You should not create a dependency rollup monitor to achieve the objective in this scenario. This type of rollup monitor is used to roll up health states from any target linked by a hosting relationship or a containment relationship. The Management Packs define the hosting and containment relationships for a target. With the combination of aggregate rollup and unit monitors, you can monitor the health status of every target.

Single answer, multiple-choice
You are the system administrator for your company. You manage a System Center Operations Manager 2007 network environment. You deploy Operations Manager 2007 agents manually on multiple application servers in your Active Directory domain. You discover that none of the agent installations were successful. You receive an error message that indicates that the new installations of manual agents have been rejected. You want to ensure the Operations Manager 2007 agents are installed successfully on all application servers. What should you do?
A. Disable the Reject new manual agent installation option.
B. Enable the Review new manual agent installations in pending management view option.
C. Disable the Auto-approve new manually installed agents option.
D. Disable the Override global Management Server settings option.
Answer:
A
Tutorial:
You should disable the Reject new manual agent installation option to achieve the objective in this scenario. From the Security tab in the Management Server Properties dialog box, you can configure various security settings for all agent-managed computers in your Operations Manager 2007 environment. The following settings can be configured under the Security tab:
• Reject new manual agent installation. When this option has been enabled, Operations Manager 2007 rejects all new manually installed agents. Enabling this option is useful when you want to reject the manual installation of the Operations Manager 2007 agents on a computer. You can allow the manual installation by disabling this option. This setting can be enabled only when the Override global Management Server settings option has been enabled.
• Review new manual agent installations in pending management view. When this option has been enabled, Operations Manager 2007 reviews all new manually installed agents. This setting must be enabled to ensure the new manually installed agent appears in the Pending Management view in the Operations Console. This setting can be enabled only when the Override global Management Server settings option has been enabled.
• Auto-approve new manually installed agents. When this option has been enabled, Operations Manager 2007 automatically approves all new manually installed agents. This setting can be enabled only when the Override global Management Server settings option and the Review new manual agent installations in pending management view option have been enabled.
• Override global Management Server settings. When this option has been enabled, Operations Manager 2007 allows global server settings to be overridden.
• Allow this server to act as a proxy and discover managed objects on other computers. When this option has been enabled, Operations Manager 2007 allows Management Server to act as a proxy.
You should not enable the Review new manual agent installations in pending management view option to achieve the objective in this scenario. When this option has been enabled, Operations Manager 2007 reviews all new manually installed agents. This setting must be enabled to ensure the new manually installed agent appears in the Pending Management view in the Operations Console.
You should not disable the Auto-approve new manually installed agents option to achieve the objective in this scenario. Enabling this option allows Operations Manager 2007 to automatically approve all new manually installed agents. Disabling this option would not achieve the objective in this scenario.
You should not disable the Override global Management Server settings option to achieve the objective in this scenario. When this setting has been enabled, global server settings in Operations Manager 2007 can be overridden. The Reject new manual agent installation option can only be enabled when the Override global server settings option has been enabled under the Security tab.
