Final answer:
Tools and techniques such as risk assessment matrix, fault tree analysis, and business impact analysis can help identify risks to services from the failure of supporting CIs.
Step-by-step explanation:
When identifying risks to services from the failure of supporting CIs like network load balancers, clusters, servers, and software, there are several tools and techniques that can help.
One such tool is a **risk assessment matrix**, which helps determine the likelihood and impact of each risk. Another technique is a **fault tree analysis**, which identifies the potential failure points in a system and their causes. Additionally, conducting a **business impact analysis** can help identify the critical services and their dependencies on supporting CIs.
