Your role of Systems Administrator at ABC.com includes the management of the company’s private
cloud.
The private cloud is hosted on an internal System Center 2012 infrastructure.
System Center 2012 Operations Manager (SCOM) is used to monitor all network devices.
The network has a leased line connection to your ISP.
A router managed by the ISP connects the leased line to the LAN.
The router is configured to allow only the ISP to access the configuration of the router to comply
with the security policy of the ISP.
You want to use System Center 2012 – Operations Manager (SCOM) to monitor the router and alert
you if the router goes offline.
You need to configure SCOM to discover the router while adhering to the ISP security policy.
Which access mode should you use?
A.
SNMPv2 only.
B.
ICMP only.
C.
ICMP and SNMPv2.
D.
SNMPv2 and SNMPv3.
Explanation:
This is a tricky question, but the answer is B, ICMP (ping) only.
The question says “Operations Manager (SCOM) is used to monitor all network devices.”… This
made me think that the answer had to be both ICMP & SNMPv2 (C), but that is wrong! It is wrong
because if we specify that a device uses both ICMP and SNMP, Operations Manager must be able to
contact the device by using both methods or discovery will fail. So it has to be B.
Also worth noting that in Operations Manager, only ONE network discovery rule can be running per
Management/Gateway server. Each server can only run one network discovery.
Here’s a good post regarding network discovery in SCOM.
