Launch and configure Chef Server on an EC2 instance and leverage the AWS CLI to launch application servers and configure those instances using Chef.Answer: AQuestion No : 13Your entire AWS infrastructure lives inside of one Amazon VPC You have an Infrastructure monitoring application running on an Amazon instance in Availability Zone (AZ) A of the region, and another application instance running in AZ B. The monitoring application needs to make use of ICMP ping to confirm network reachability of the instance hosting the application.Can you configure the security groups for these instances to only allow the ICMP ping to pass from the monitoring instance to the application instance and nothing else'' If so how?A. No Two instances in two different AZ's can't talk directly to each other via ICMP ping as that protocol is not allowed across subnet (iebroadcast) boundariesB. Yes Both the monitoring instance and the application instance have to be a part of the same security group, and that security group needs to allow inbound ICMPC. Yes, The security group for the monitoring instance needs to allow outbound ICMP and the application instance's security group needs to allow Inbound ICMPD. Yes, Both the monitoring instance's security group and the application instance's security group need to allow both inbound and outbound ICMP ping packets since ICMP is not a connection-oriented protocolAnswer: CQuestion No : 14 - (Topic 1)You are managing a legacy application Inside VPC with hard coded IP addresses in its configuration.Which two mechanisms will allow the application to failover to new instances without the need for reconfiguration?
