B. A VPLS plug-in is installed on the Server.
C. An IP-VPN plug-in is installed on the Windows 2000 Client.
D. A VPLS plug-in is installed on the UNIX Client.
Answer: B
Question: 6
A customer installed Optivity NMS (ONMS) 10.3. They want to do network discovery using the Auto
Topology Manager but they want to discover only devices and nodes belonging to certain subnet range since
that subnet ranges. How do they have to configure the Auto Topology Manager to satisfy this request?
A. Configure the corresponding discovery seed with the requested subnet range.
B. Configure the corresponding discovery seed with the address of the first and the last device belonging to
that subnet range.

C. Configure the corresponding discovery seed to look only for new nodes, and devices will be automatically
found.
D. Create a new discovery seed which will look only for new devices and nodes.
Answer: A
Question: 7
A customer installed Enterprise NMS (ENMS) Rls. 10.4. They performed network discovery using
Auto Topology Manager. They used the topology process which did the following:
Used information previously added to the Enterprise database to locate Nortel devices within subnets.
Subnet topology queries of the Nortel devices about device and logical topology, but does NOT queries
about workstations or end nodes. The topology process that filters out Nortel devices from non-Nortel
devices and updates the database to account for these devices. What was the topology process (application)
used by the customer in the network discovery process?
A. Data Link Layer Topology - topst
B. Network Layer Topology - toprt
C. End Node Topology - topdt
D. Protocol Discovery - protur, protmr, protfr
Answer: A
Question: 8
An organization recently asked you to split their devices into two sets with different authentication keys.
They have been working with the IP range 134.177.133.0-49 and want the new sub-group to be
134.177.133.36-40. You just made the community string changes by entering the new subgroup in the IP
range table just below the 134.177.133.0-49 group. When verifying the changes, you see trap registration
failures for all the devices in the new sub-group. You realize Auto topology has failed to discover the new
sub-group since its entry is after, rather than before, the larger IP range. How can you correct this issue with
the least amount of effort?
A. Delete the 134.177.133.0-49 IP range.
Re-create it in the IP range table below the sub-group IP range. Enter the parameters. Save all changes.
B. Delete the 134.177.133.0-49 IP range and create 2 new IP groups. One for 134.177.133.0-35 in the IP
range table above the sub-group IP range and enter the parameters.
The second new group would be 134.177.133.40-49 below the sub-group IP range, and entered with the
parameters. Save all changes.
C. Delete the sub-group IP range. Create the appropriate 5 individual IPs in the specific IP table and enter the
parameters. Save all changes.

D. Select the sub-group IP range in the IP range table. Use the up arrow key to move it above the 134.177.0-
49 IP range. Save all changes.
Answer: D
Question: 9
You are managing events with the Fault Summary application on an Enterprise Network Management
System (ENMS) Rls. 10.4 system in a Windows environment. Although you have reports of alarm conditions
on your network, you have noticed that the Fault Summary window fails to display any faults even when a
device sends a trap. What should you do to resolve this issue?
A. Check that the trap server and Fault Correlator daemon are running.
B. Check that the trap server and Fault Correlator service are running.
C. Check that the weboptsrvr service is running.
D. Check that weboptsrvr service is running and restart the Fault Summary application.
Answer: B
Question: 10
A customer has Enterprise Network Management System (ENMS) Rls. 10.4 installed. What is the correct
statement about syslog events?
A. They are events reported by devices with the Syslog protocol and Fault Summary reports syslog events as-
received, without any correlation or processing
B. They are network events reported by Fault Correlator engine running on ENMS Server and
Fault Summary reports processed syslog events
C. They are network events reported by Fault Correlator with the SNMP protocol and Fault
Summary reports syslog events as-received, without any correlation or processing
D. They are events reported by devices with the Syslog protocol and Fault Summary reports correlated syslog
events
