Question:
Which of the following are characteristics of a highly observable system? Select all that apply

1. Low latency for requests
2. High availability of services
3. Ability to trace requests across multiple services
4. Limited data collection and analysis

Answer:
B - is correct. High availability of services is important because it ensures that the system is accessible and that data can be collected
C - is correct. The ability to trace requests across multiple services is also important because it allows teams to understand the flow of requests through the system
A - incorrect. Low latency for requests is desirable, but it is not necessarily a characteristic of a highly observable system
D - incorrect. Limited data collection and analysis is not a characteristic of a highly observable system, as observability relies on collecting and analyzing data to understand the behavior of the system
