Choose 3 answers from the options given below

Answer options:

B.Configure your test so each client makes an independent DNS request
C.Ensure that the request goes to the first IP returned by the DNS
D.spread your client requests across the set of IP addresses that are returned by DNS

Answer - A,B and D
The following should be considered
· Send client requests from multiple geographic regions.
· Configure your test so each client makes an independent DNS request; each client will then receive a different set of IP addresses from DNS.
· For each client that is making requests, spread your client requests across the set of IP addresses that are returned by DNS, which ensures that the load is distributed across multiple servers in a CloudFront edge location.
