Correct Answer : Get Lastest Questions and Answer :

Explanation: The Load Balancer intercepts the traffic from the client and routes it to the back-end instance. When the app at the instance level receives the
request, it gets the IP address of ELB in the request. To get the IP address of the client, the Proxy protocol is required to be enabled at ELB. When the
Proxy protocol is enabled, the Load Balancer adds a human-readable format header that contains the connection information, such as the source IP address,
destination IP address and the port numbers of the client

Question : You have a Linux EC 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?



1. 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
2. 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

since the networking stack of the OS may be locked up causing the "impaired" system status.
4. 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
5. un-map and then re-map the EIP to the instance, since the IGW/NAT gateway may not be
working properly, causing the "impaired" system status
