You are configuring a VirtualService for the 'payments' service. You want to inject a 3-second delay for 10% of requests that carry the header 'x-test: true'. Which fault configuration accomplishes this while leaving all other traffic unaffected?
A platform operator needs to inject a 2-second delay into 10% of requests sent to the 'reviews' service so that callers exercise their client-side timeout logic. The team has already created a VirtualService that routes all traffic to the reviews service and wants to apply the delay only to a subset of requests. Which VirtualService configuration accomplishes this?
You are configuring a DestinationRule for the 'inventory' service to improve resilience. You want to set up outlier detection to eject unhealthy hosts. Which TWO fields are required to enable outlier detection and specify the criteria for ejection? (Choose two.)
A site reliability engineer is tuning a DestinationRule for the 'payments' service. The goal is to eject a pod from the load-balancing pool when it returns five consecutive 5xx errors, but only for 30 seconds, after which the pod should be reconsidered. The team also wants to ensure that at most 40% of the endpoints can be ejected at any time. Which combination of OutlierDetection settings achieves this?
You are using Istio to manage traffic to a legacy service that occasionally returns HTTP 500 errors. You want to configure retries so that the sidecar retries failed requests up to 3 times, but only for idempotent GET requests. Which VirtualService configuration achieves this?
A developer is configuring a VirtualService for the 'inventory' service. The service occasionally returns transient 503 errors, and the team wants the sidecar to retry failed requests up to three times with a 1-second timeout per attempt, but only for requests that use the GET method. Which retry configuration in the VirtualService accomplishes this?
You are configuring connection pool settings for the 'checkout' service in a DestinationRule. You want to limit the number of concurrent HTTP/2 requests to 100 and ensure that excess requests are queued up to a maximum of 50. Which configuration snippet correctly sets these limits?
To test how your application handles service unavailability, you want to return an HTTP 503 error for 20% of requests to the 'catalog' service. Which fault injection setting do you use?
You need to limit the number of concurrent connections to the 'order-service' to prevent cascading failures. Which Istio resource should you configure?
You have a DestinationRule with outlier detection enabled. If a host returns 5 consecutive 5xx errors and the 'interval' is set to 1s, what happens if 'baseEjectionTime' is 30s?
You need to ensure that a request to the 'orders' service times out if it takes longer than 2 seconds. Which field in the VirtualService should you configure?
To test the resilience of your microservice architecture, you want to introduce a 5-second delay to 50% of the requests directed to the 'catalog-service'. Where do you define this configuration?
You want to configure your microservice to be more resilient. Which THREE of the following are valid fields within an 'outlierDetection' policy in a DestinationRule?
An application is experiencing intermittent errors. You decide to use outlier detection to eject unhealthy pods. Which field in the DestinationRule controls the ejection of hosts after a certain number of 5xx errors?
A service is returning 5xx errors frequently. You want to eject instances that return 5 consecutive 5xx errors. Which OutlierDetection setting is required?
You notice that a pod is being ejected by Outlier Detection despite only having occasional errors. How do you increase the interval between ejection scans?
You configure a VirtualService for the 'payments' service with an HTTP route that applies a retry policy of 3 attempts with a 2s perTryTimeout, and a global timeout of 5s. During peak load, callers report that requests fail after roughly 5 seconds even though some retries were still in flight. Which behavior of the global timeout explains this?
You are reviewing a VirtualService for the 'reviews' service. The service has a timeout of 5 seconds configured. You want to ensure that if a request takes longer than 5 seconds, it is aborted with a 504 Gateway Timeout. Which field in the VirtualService should you configure?
A cluster administrator wants to limit the number of concurrent connections and pending requests that the sidecar will allow to the 'shipping' service. The team also wants to configure a circuit breaker that trips when the number of pending requests exceeds a threshold. Where should these settings be defined?
A platform team is implementing a resilience strategy for the 'checkout' service. They want to configure a DestinationRule that ejects unhealthy hosts, and they also want to ensure that the ejection does not remove too many hosts at once. Which TWO settings in the OutlierDetection configuration directly control how many hosts can be ejected and how long they remain ejected? (Choose two.)
