You created a VPC that has a public subnet and a private subnet. A web server was placed in the public subnet and a database server was placed in the private subnet. The web server is able to connect to the database server; however, the database server at 10.0.1.2 is unable to get software updates. What is the cause of this issue? The router is not configured properly on the VPC. Add a route to route table for the VPC that routes all traffic for 0.0.0.0/0 to the ID of the internet gateway. There is no egress-only internet gateway attached to the private subnet of the VPC There is no NAT gateway for the private subnet, so the database server has no routes that give it public internet access to download software updates. The database server needs to be assigned a public address from the pool, or assigned an Elastic IP similar to the instance 10.0.0.2. 2 / 14 2. All the Amazon EC2 instances you launch into a nondefault VPC are ___ by default. public stateless protected private 3 / 14 3. How do you limit access to an S3 bucket by source IP address? You can not limit access to an S3 bucket by IP address. In the preperties of the S3 bucket, add an access control option that limit access to the bucket by source IP address. Input the list of IPs into dialog. Create the S3 bucket as a target for Application Load Balancer. Use Web Application Firewall (WAF) to create a rule to limit access to the S3 bucket by source IP. Create a bucket policy with a condition that limit access to a list of approved IP addresses. Attach this policy to the bucket. 4 / 14 4.

You are running Docker containers on ECS. What is the most important metric to monitor? The running container count for each service from within CloudWatch. Monitor the EC2 service dashboard. Watch for posted outages to the ECS service. The memory consumption of each EC2 instance in your cluster from within CloudWatch. The instance health of each EC2 instance in your cluster from within CloudWatch. 10 / 14 10. Use the ___ protocol in a VPC security group to communicate with a DB instance. TCP UDP SSL SSH 11 / 14 11. What is the best EC2 instance class for a server that continuously has a heavy CPU load? T2 R5 C5 H1 12 / 14 12.
