SCP-NPM Exam Topic 2 Question 17 Discussion:
Question #: 17
Topic #: 2
Network performance over an inter-campus Ethernet link is slow. One side of the connection is experiencing a high number of packet drops. What information in NPM can you review to help discover the cause of the issue?
A.
Packet loss on the nodes on either side of the connection
Packet loss is a measure of how many packets are lost or discarded during transmission over a network. Packet loss can cause network performance issues such as slow response time, jitter, and degraded voice quality. NPM can monitor packet loss on nodes and interfaces using ICMP ping or SNMP statistics. You can review the packet loss metrics on the Node Details or Interface Details views, or create a custom chart or report to compare packet loss across multiple nodes or interfaces. By reviewing the packet loss on the nodes on either side of the connection, you can identify which node or interface is experiencing the problem and troubleshoot the root cause. You can also use the Performance Analysis dashboard (PerfStack) to correlate packet loss with other metrics such as response time, CPU load, memory usage, buffer misses, and interface errors123.
