What is the purpose of probe rules file caching (e.g. the CacheRulesFile property)?
It provides a system for storing a probe's last known working rules file and using it in the case when the probe is restartedwith an unavailable or invalid local rules file.

A company wants to integrate LDAP with the WebGUI server. The system administrator, with the assistance of their LDAP admin, have configured the system to a point where they can view groups in Manage Groups and users in Manage Users. They have assigned ncw* roles to the groups, however, the LDAP users and groups are not synchronized to the ObjectServer. Which two WebGUI files do they need to check to troubleshootthis problem? (Choose two.)
A company has a virtual pair of ObjectServers with the primary located in London (emea.fqdn.com 4100), and the backup is in Perth (apac.fqdn.com 4100), while WebGUI is in San Francisco (usa fqdn com 16310) The administrator runs this command ./confvm4ncos.sh root netcool emea.fqdn.com 4100 apac.fqdn.com 4100 This part of the command, confvmm4ncos.sh, updates the WebGUI ObjectServer connection details for what?
The WAAPI host, port, username, password is configured in which file?
What are wires used for when developing a custom set of pages in the WebGUI portal?

If UNIX authentication is used by a ProcessAgent, which check is made for any incoming connection to be accepted?
The user must be a member of the ncoadmin group (or whatever the -admingroup property is set to).
The network operation center has two groups of users that use the native desktop One group, OPERATIONS, requires access to the standard event management tools like acknowledge and delete. They also require access to some custom tools for things like basic troubleshooting (ping and telnet) and ticket creation. The second group, NETWORK, requires access to the same tools used by the OPERATIONS group users. In addition, there are a few tools used for advanced router diagnostics that they use. These tools are not to be available to the OPERATIONS group users. To minimize administration efforts a common desktop menu is used for both groups of users. The RouterDiag tool, used by NETWORK users, is defined in a menu called DiagTools. The tool is only used for Acme routers. The Acme routers produce SNMP traps, which are converted to events by the MTTrapd probe. Which option limits this tool for use with only Acme routers?
configure the mttrapd.rules file to populate the alerts.status Class column with the value 9999; configure the RouterDiagtool to limit access to only the 9999 Class

A company is deploying a multi-tiered architecture with a collection, aggregation, and display layers. Which steps are required to create a pair of collection layer ObjectServers?
Configure the omni.dat or Server Editor and generate the interfaces file for COL_P_1, COL_B_1 and COL_V_1Run nco_dbinit with the -customconfigfile option to load the collection.sql to initialize the ObjectServers.Start the ObjectServers COL_P_1 and COL_B_1.
IBM Tivoli Netcool/OMNIbus V7 4 core components are being installed on a server running 64-bit SUSE Linux. The server hardware consists of 8 CPUs (2.4 GHz), 16 GB RAM, and 2500 GB disks. The software will be installed using the Typical installation option Which statement is true about system hardware requirements?
The hardware on this system is adequate for most small to medium deployments.
An installation of an ObjectServer on Redhat Linux has completed. The ObjectServer has been set up to use PAM authentication. What must be increased to keep nco_pad from crashing?

Mode, PeerHost, PeerPort
Which statement correctly describes what occurs when the Maintain History option is selected in the Accelerated Event Notification (AEN) client property settings?

Which two actions are required when configuring a CGI script to use via a WebGUI tool? (Choose two.)
ensure the script is executable

An executable tool is created for use through the native desktop. The tool runs a .bat file that performs a ping command on Windows desktops. The tool is created but does not work. What describes the correct technique for diagnosing the problem with this tool?
configure the Redirect errors option in the tool to display any errors in a pop-up window
What is the default location of the localization configuration file on a Linux host?
An ObjectServer trigger is configured to locate all critical events related to a very important network component. The trigger generates an event-based Accelerated Event Notification (AEN) The AEN message is sent to all users that are members of the NETWORK group. The trigger updates the event so that it will not send another AEN message for the same event. When the trigger runs and generates the AEN message there are no users that belong to the NETWORK group that have an active AEN client running on their desktops. What happens to the AEN message is this situation?
With no active clients to receive the message, the message is lost.
