The correct answer is A. The profile optimized for east-west traffic in cloud and on-premises data centers is Cloud/Data Center. Official R82 Autonomous Threat Prevention profile descriptions identify Cloud/Data Center as optimized to prevent cyberattacks on data centers, including extensive protection over servers and east-west traffic. Option B, Internal Network, is used for internal network protection, but the question specifically names cloud and on-premises data centers and east-west traffic, which points to Cloud/Data Center. Option C is wrong because Guest Network is focused on guest-user segments. Option D is wrong because Perimeter focuses on north-south perimeter gateway exposure, not lateral data center communication. For exam purposes, associate “servers,” “data center,” and “east-west traffic” with Cloud/Data Center.
