Amazon Web Services AWS Certified Solutions Architect - Professional SAP-C02 Question # 83 Topic 9 Discussion

SAP-C02 Exam Topic 9 Question 83 Discussion:
Question #: 83
Topic #: 9

A company is planning to migrate its on-premises data analysis application to AWS. The application is hosted across a fleet of servers and requires consistent system time.

The company has established an AWS Direct Connect connection from its on-premises data center to AWS. The company has a high-precision stratum-0 atomic clock network appliance that acts as an NTP source for all on-premises servers.

After the migration to AWS is complete, the clock on all Amazon EC2 instances that host the application must be synchronized with the on-premises atomic clock network appliance.

Which solution will meet these requirements with the LEAST administrative overhead?
A.

Configure a DHCP options set with the on-premises NTP server address. Assign the options set to the VPC. Ensure that NTP traffic is allowed between AWS and the on-premises networks.

B.

Create a custom AMI to use the Amazon Time Sync Service at 169.254.169.123. Use this AMI for the application. Use AWS Config to audit the NTP configuration.

C.

Deploy a third-party time server from the AWS Marketplace. Configure the time server to synchronize with the on-premises atomic clock network appliance. Ensure that NTP traffic is allowed inbound in the network ACLs for the VPC that contains the third-party server.

D.

Create an IPsec VPN tunnel from the on-premises atomic clock network appliance to the VPC to encrypt the traffic over the Direct Connect connection. Configure the VPC route tables to direct NTP traffic over the tunnel.
