You have built an application that is deployed with an Elastic Load Balancer and an Auto Scaling Group. As a Solutions Architect, you have configured aggressive CloudWatch alarms, making your Auto Scaling Group (ASG) scale in and out very quickly, renewing your fleet of Amazon EC2 instances on a daily basis. A production bug appeared two days ago, but the team is unable to SSH into the instance to debug the issue, because the instance has already been terminated by the ASG. The log files are saved on the EC2 instance.How will you resolve the issue and make sure it doesn't happen again?Disable the Termination from the ASG any time a user reports an issueInstall a CloudWatch Logs agents on the EC2 instances to send logs to CloudWatchMake a snapshot of the EC2 instance just before it gets terminatedUse AWS Lambda to regularly SSH into the EC2 instances and copy the log files to S3
You want to decrease your risk of developing an infectious disease. Which of the following factors can you control?- Heredity- Nutritional status- Environmental conditions- Age
The regulatory sequences of the operon controlling arabinose metabolism (ara operon) were studied to determine whether bacteria can respond to changes in nutrient availability. It is predicted that if those regulatory sequences are functioning properly, the bacteria will produce the enzymes involved in arabinose metabolism (structural genes B, A, and D) in the presence of arabinose.If a gene that encodes a green fluorescent protein (GFP) is substituted for the structural genes of the operon, activation of the regulatory sequences can be assayed by GFP expression. A culture of E. coli cells underwent a transformation procedure with a plasmid containing the regulatory sequences of the ara operon directly upstream of the gene encoding the GFP. The plasmid also confers ampicillin resistance to bacteria. Samples were then plated on different types of culture media. (Note: The GFP fluoresces only under UV light, not under white light.) The table below shows the results.Which of the following can best be used to justify why the GFP is expressed by E. coli cells after transformation with the plasmid?AThe presence of arabinose in the nutrient agar activated the expression of the genes located downstream of the ara operon regulatory sequences.BThe combination of ampicillin and arabinose in the nutrient agar inhibited the expression of certain gene products, resulting in the increased expression of the GFP.CThe nutrient agar without arabinose but with ampicillin activated the expression of the genes located downstream of the ara operon regulatory sequences.DBoth arabinose and ampicillin were required in the nutrient agar to activate the expression of genes located downstream of the ara operon regulatory sequences
