   An API client is experiencing slow responses due to high network latency. How does increased network latency affect the request/response cycle?

   • AIt automatically increases the client-side timeout value
   • BIt increases the time it takes for the request to reach the server and the response to return
   • CIt causes the API to return HTTP 429 status codes
   • DIt reduces the maximum payload size the API can accept

   A security analyst is building a script that queries a threat intelligence API to enrich IP addresses. The script runs every hour and processes about 500 IPs. After the first 100 requests, the API starts returning HTTP 429 with a Retry-After header of 60 seconds. The analyst needs to complete the enrichment without exceeding the rate limit and without waiting too long. What should the analyst implement?

   • ASwitch the script to use XML instead of JSON for the request payload.
   • BIncrease the timeout value on the HTTP client to 120 seconds.
   • CSend all 500 IPs in a single POST request to reduce the number of calls.
   • DParse the Retry-After header and pause the script for that duration before retrying.

   A security analyst is integrating a SIEM API that returns JSON responses. The API documentation specifies that the 'severity' field can be 'low', 'medium', or 'high'. In a response, the analyst receives a 'severity' field with the value 'critical'. The analyst's code currently maps any unknown severity to 'high'. The analyst needs to ensure that the integration handles this correctly. What should the analyst do?

   • AMap 'critical' to 'high' because it is a higher severity than 'medium'.
   • BIgnore the 'severity' field and use a default value of 'low'.
   • CRetry the request to see if the API returns a different value.
   • DLog the unexpected value and treat it as an error or unknown severity.
