D.Network scale

E.Network medium

A.Check whether all non-backbone areas are correctly and reliably connected to the backbone area.

B.Verify that OSPF costs can correctly demonstrate the actual bandwidth of links at more than 100 Mbit/s.

C.Check the OSPF network topology and ensure that no loop exists when OSPF routes are being calculated.

D.Check whether secondary optimal routes exist on the network according to OSPF route selection rules.

E.Determine that the backbone area will not split.

A.After configuration file backup is configured, the NMS automatically compares differences between configuration files. When obtaining the configuration change, the NMS generates an alarm, which, however, cannot be notified to the preset contact through an email.

B.The performance management function does not allow the NMS to collect statistics about performance data.

C.During performance management, the NMS presets default thresholds for key performance counters. If a counter exceeds the threshold, an alarm is generated.

D.The alarm management function does not allow the NMS to directly display alarm information about devices and ports on the topology.

A.Switches supporting STP edge ports

B.Switches supporting PoE

C.Switches supporting SACG

D.Switches supporting QoS
