Question 253

You use a VPN to extend your corporate network into a VPC. Instances in the VPC are able to resolve resource records in an Amazon Route 53 private hosted zone. Your on-premises DNS server is configured with a forwarder to the VPC DNS server IP address. On-premises users are unable to resolve names in the private hosted zone, although instances in a peered VPC can. What should you do to provide on-premises users with access to the private hosted zone?

Create a proxy resolver within the VP

Point the on-premises forwarder to the proxy resolver.

Modify the network access control list on the VPC to allow DNS queries from on-premises systems.

Configure the on-premises server as a secondary DNS for the private zone. Update the NS records.

Update the on-premises forwarders with the four name servers assigned to the private hosted zone.

A company hosts its application, example.com, behind Application Load Balancers in the us-east-1 and eu-west-1 Regions.

Users should be routed to the resources geographically nearest to them. Users must not be routed to the application when it is considered unhealthy. How should a network engineer configure Amazon Route 53 to route clients to example.com?

Configure latency.example.com to use a weighted routing policy that points to the load balancers, and associate an HTTPhealth check. Configure failover records for example.com. Point the primary alias record to latency.example.com,and enablethe evaluate target health setting. Point the secondary record to a static HTML maintenance page hosted in Amazon S3.

Configure latency.example.com CNAME latency-based records that point to the load balancers, and associate an HTTPhealth check. Configure failover records for example.com. Point the primary alias record to latency.example.com,and enablethe setting used to evaluate target health. Point the secondary record to a static HTML maintenance page hosted in AmazonS3.

Configure latency.example.com to use a geoproximity routing policy that points to the load balancers, and associate an HTTP health check. Configure failover records for example com.

Create an inbound rule in the VPC's network ACL that matches the TCP port. Create an Amazon CloudWatch alarm on the NetworkPackets metric for the ACL that uses Amazon SNS to notify the Administrator when the metric is greaterthan zero.

Install intrusion detection software on each Amazon EC2 instance and configure it to use the AWS CLI to notify the Administrator with Amazon SNS each time the TCP port is accessed.

Create VPC Flow Logs that write to Amazon CloudWatch Logs, with a metric filter matching connections on the required port. Create a CloudWatch alarm on the resulting metric that uses Amazon SNS to notify the Administrator whenthe metric is greater than zero.

Install intrusion detection software on each Amazon EC2 instance and configure it to use the AWS CLI to publish to a custom Amazon CloudWatch metric each time the TCP port is accessed. Create a CloudWatch alarm on the resultingmetric that uses Amazon SNS to notify the Administrator when the metric is greater than zero.
