   A network automation script retries failed API requests with a fixed 1-second delay. The API occasionally returns 429 with a Retry-After header of 60 seconds. The script also retries on 500 errors. The script is causing a high number of requests and the API provider is threatening to block the client. What is the best retry strategy?

   • AIncrease the fixed delay to 5 seconds for all retries
   • BRetry immediately on 429 and 500 to get the data faster
   • CUse exponential backoff with jitter and honor the Retry-After header
   • DOnly retry on 500 errors and ignore 429

   • BConvert the field to uppercase before comparison
   • CUse the exact case-sensitive values from the schema in the comparison
