Kubernetes - Service Mesh

Given the following Istio configuration snippet for telemetry, what will be the effect?

apiVersion: telemetry.istio.io/v1alpha1
kind: Telemetry
metadata:
  name: example-telemetry
spec:
  metrics:
  - providers:
    - name: prometheus
    overrides:
      prometheus:
        defaultHistogramBuckets: [0.1, 0.5, 1, 5]

APrometheus will ignore histogram buckets and use defaults

BPrometheus will collect metrics with custom histogram buckets 0.1, 0.5, 1, and 5

CTelemetry resource will cause an error due to invalid syntax

DMetrics will be sent to Jaeger instead of Prometheus

Step-by-Step Solution

Solution:

Step 1: Analyze the Telemetry resource configuration
The snippet sets a Telemetry resource specifying Prometheus as the metrics provider and overrides histogram buckets to [0.1, 0.5, 1, 5].
Step 2: Understand the effect on Prometheus metrics
This means Prometheus will collect metrics using these custom histogram buckets instead of defaults.
Final Answer:
Prometheus will collect metrics with custom histogram buckets 0.1, 0.5, 1, and 5 -> Option B
Quick Check:
Telemetry config with overrides = custom Prometheus buckets [OK]

Quick Trick: Overrides in Telemetry change Prometheus buckets [OK]

Common Mistakes:

Assuming default buckets remain unchanged
Confusing metrics destination as Jaeger
Thinking syntax is invalid without error
