74번 답안은 A > C.로 다시 정정하도록 하겠습니다. 설명은 문제에도 추가하였습니다.
A is not correct because increasing the memory size will not improve persistent disk throughput.
B is not correct because the DB administration team is requesting help with their MySQL instance Migration to a different product should not be the solution when other optimization techniques can still be applied first.
C is correct because persistent disk performance is based on the total persistent disk capacity attached to an instance and the number of vCPUs that the Instance has Incrementing the persistent disk capacity will increment ns throughput and IOPS, which In turn improve the performance of MySQL.
D is not correct because the DB administration team is requesting help with their MySQL instance Migration to a different product should not be the solution when other optimization techniques can still be applied first.
그리고 78번 답안은 B. Choose larger instances for your database. 로 변경하였습니다. 용량 부족해서 발생한 이슈이므로 HA 구성에 대한 검토 전에 먼저 용량 증설이 우선일 것으로 판단됩니다.
