A company recently deployed an application in production.The production environment currently runs on a single Amazon EC2 instance that hosts the application’s web application and a MariaDB database.Company policy states that all IT production environments must be highly available.What should a SysOps administrator do to meet this requirement?Read More →

A company’s VPC has an existing IPv4 configuration.The IPv4 configuration includes public subnets, private subnets, NAT gateways, default route tables, and ACLs.The company associates an IPv6 CIDR block with the VPC.The company adds IPv6 allocations to each existing subnet and adds routes to the route tables.The company updates the ACLs to allow all IPv6 traffic.Public subnets are working as expected, but private subnets are not allowing internet IPv6 connections.What should a SysOps administrator do to allow outbound-only connectivity for the new IPv6 subnets?Read More →

A SysOps administrator is troubleshooting a VPC with public and private subnets that leverage custom network ACLs.Instances in the private subnet are unable to access the internet.There is an internet gateway attached to the public subnet.The private subnet has a route to a NAT gateway that is also attached to the public subnet.The Amazon EC2 instances are associated with the default security group for the VPC.What is causing the issue in this scenario?Read More →

Accompany wants to monitor the number of Amazon EC2 instances that it is running.The company also wants to automate a service quota increase when the number of instances reaches a specific threshold.Which solution meets these requirements?Read More →

A user is connected to an Amazon EC2 instance in a private subnet.The user is unable to access the internet from the instance by using the following curl command: curl http:/www.example.com.A SysOps administrator reviews the VPC configuration and learns the following information:• The private subnet has a route to a NAT gateway for CIDR 0.0.0.0/0• The outbound security group for the EC2 instance contains one rule: outbound for port 443 to CIDR 0.0.0.0/0• The inbound security group for the EC2 instance allows ports 22 and 443 from the user’s IP address.• The inbound network ACL for the subnet allows port 22 and port range 1024-65535 from CIDR 0.0.0.0/0Which action will allow the user to complete the curl request successfully?Read More →

A SysOps administrator needs to create alerts that are based on the read and write metrics of Amazon Elastic Block Store (Amazon EBS) volumes that are attached to an Amazon EC2 instance.The SysOps administrator creates and enables Amazon CloudWatch alarms for the DiskReadBytes metric and the DiskWriteBytes metric.A custom monitoring tool that is installed on the EC2 instance with the same alarm configuration indicates that the volume metrics have exceeded the threshold.However, the CloudWatch alarms were not in ALARM state.Which action will ensure that the CloudWatch alarms function correctly?Read More →
