You have a Linux EC2 web server instance running inside a VPC The instance is In a public subnet and has an EIP associated with it so you can connect to It over the Internet via HTTP or SSH The instance was also fully accessible when you last logged in via SSH. and was also serving web requests on port 80. 

Now you are not able to SSH into the host nor does it respond to web requests on port 80 that were working fine last time you checked You have double-checked that all networking configuration parameters (security groups route tables. IGW'EIP. NACLs etc) are properly configured {and you haven’t made any changes to those anyway since you were last able to reach the Instance). You look at the EC2 console and notice that system status check shows "impaired." 

Which should be your next step in troubleshooting and attempting to get the instance back to a healthy state so that you can log in again? 

A. Stop and start the instance so that it will be able to be redeployed on a healthy host system that most likely will fix the "impaired" system status 

B. Reboot your instance so that the operating system will have a chance to boot in a clean healthy state that most likely will fix the 'impaired" system status 

C. Add another dynamic private IP address to me instance and try to connect via mat new path, since the networking stack of the OS may be locked up causing the “impaired” system status. 

D. Add another Elastic Network Interface to the instance and try to connect via that new path since the networking stack of the OS may be locked up causing the "impaired" system status 

E. un-map and then re-map the EIP to the instance, since the IGWVNAT gateway may not be working properly, causing the "impaired" system status

B. Use the Cloud Watch CLI tools to pull the respective metrics from each regional endpoint Aggregate the data offline & store it for graphing in CloudWatch. 

C. Add SNMP traps to each instance and DynamoDB table Leverage a central monitoring server to capture data from each instance and table Put the aggregate data into Cloud Watch for graphing. 

D. Add a CloudWatch agent to each instance and attach one to each DynamoDB table. When configuring the agent set the appropriate application name & view the graphs in CloudWatch.
