A SysOps administrator created an Amazon VPC with an IPv6 CIDR block, which requires access to the internet. However, access from the internet towards the VPC is prohibited. After adding and configuring the required components to the VPC, the administrator is unable to connect to any of the domains that reside on the internet.
What additional route destination rule should the administrator add to the route tables?

  1. Route ::/0 traffic to a NAT gateway
  2. Route ::/0 traffic to an internet gateway
  3. Route 0.0.0.0/0 traffic to an egress-only internet gateway
  4. Route ::/0 traffic to an egress-only internet gateway

A company hosts several write-intensive applications. These applications use a MySQL database that runs on a single Amazon EC2 instance. The company asks a SysOps administrator to implement a highly available database solution that is ideal for multi-tenant workloads.
Which solution should the SysOps administrator implement to meet these requirements?

  1. Create a second EC2 instance for MySQL. Configure the second instance to be a read replica.
  2. Migrate the database to an Amazon Aurora DB cluster. Add an Aurora Replica.
  3. Migrate the database to an Amazon Aurora multi-master DB cluster.
  4. Migrate the database to an Amazon RDS for MySQL DB instance.

Answer(s): C



A company has a memory-intensive application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer (ELB). The instances run in an Auto Scaling group. A SysOps administrator must ensure that the application can scale based on the number of users that connect to the application.
Which solution will meet these requirements?

  1. Create a scaling policy that will scale the application based on the ActiveConnectionCount Amazon CloudWatch metric that is generated from the ELB.
  2. Create a scaling policy that will scale the application based on the mem_used Amazon CloudWatch metric that is generated from the EL
  3. Create a scheduled scaling policy to increase the number of EC2 instances in the Auto Scaling group to support additional connections.
  4. Create and deploy a script on the ELB to expose the number of connected users as a custom Amazon CloudWatch metric. Create a scaling policy that uses the metric.

Answer(s): A



A SysOps administrator creates a new VPC that includes a public subnet and a private subnet. The SysOps administrator successfully launches 11 Amazon EC2 instances in the private subnet. The SysOps administrator attempts to launch one more EC2 instance in the same subnet. However, the SysOps administrator receives an error message that states that not enough free IP addresses are available.
What must the SysOps administrator do to deploy more EC2 instances?

  1. Edit the private subnet to change the CIDR block to /27.
  2. Edit the private subnet to extend across a second Availability Zone.
  3. Assign additional Elastic IP addresses to the private subnet.
  4. Create a new private subnet to hold the required EC2 instances.

Answer(s): D
