アプリケーション チームが新しいアプリケーションをデプロイしています。アプリケーション チームは、ネットワーク チームがネットワーク パフォーマンスを監視し、そのトラフィックの往復時間の変動が発生した場合にアラートを作成することを望んでいます。
この要件を満たすためにネットワーク チームが監視する必要があるのは次のうちどれですか?
正解:B
Explanation
Latency, also known as round-trip time (RTT), is the time it takes for a data packet to travel from a source to its destination and back again. It is a key indicator of network performance and can be used to identify fluctuations that may impact the user experience of an application.
Bandwidth, loss, and cyclic redundancy check (CRC) are other important network performance metrics, but they are not directly related to the application team's requirement to monitor for fluctuations in RTT.

The network team can use a variety of tools and techniques to monitor RTT, such as ping, traceroute, and network monitoring software.
When setting up alerts, the network team should consider the acceptable range of RTT for the application. They should also configure alerts to trigger at different levels of severity, so that they can take prompt action to resolve any issues.
