Arcitura Education S90.18 Exam - Topic 5 Question 31 Discussion

Actual exam question for Arcitura Education's S90.18 exam

Question #: 31
Topic #: 5

Service A is an agnostic service that currently uses message-layer security implemented by symmetric encryption. However, because Service A has recently been successfully attacked, it has been decided that asymmetric encryption needs to be used instead. The nature of the messages exchanged by Service A requires that only some parts of the message data need to be encrypted. Although it is agreed that asymmetric encryption is required, architects are concerned that it will adversely affect the service's runtime performance. Which of the following approaches will fulfill these security requirements with the least amount of performance degradation?

AAn authentication broker needs to be introduced with a dedicated identity store.

BOnly the required parts of the message need to be encrypted instead of encrypting the entire message.

CThe Direct Authentication pattern needs to be applied so that no intermediary is involved between Service A and its service consumers.

DCertificates need to be issued by a registered certificate authority.

I might lean towards option D, $59,000 F, but I'm not sure if I got all the calculations right during my review sessions.
