You get these credits when your CPU is idle. If your CPU credits are not used they are credited to your account and they stay there for 24 hours. Based on your credit balance, you can decide whether the t2 instance, should be scaled up or down. Therefore, when an EBS volume is attached to an optimized instance, single digit millisecond latencies can be achieved. Instances launched into a common placement group are put in a logical group that provides high-bandwidth, low latency between all the instances in the group. Instances which are not a part of that group are limited to 5 Gbps speed in multi flow traffic. Cluster Networking is ideal for high performance analytics system.
How will these changes be effective? Answer: Changes are automatically applied to windows instances Q71 Load Balancer and DNS service comes under which type of cloud service? You want to create another Encrypted volume from this unencrypted volume.

It was noted that every month to around the 4GB of sensor data are generated. The pilot was success and now they want to the deploy take atleast K sensors.
You need to the stored data for at least 2 years to an analyze it. Answer:Used on Application Load Balancer. Q85 How will change the instance give type for the instances, which are the running in your applications tier and Then using Auto Scaling.
Where will you change it from areas? Which option will be reduce load on the site EC2 instance? Q87 What does the Connection of draining do?
Q88 When the instance is an unhealthy, it is do terminated and replaced with an new ones, which of the services does that?
Q89 What are the life cycle to hooks used for the AutoScaling? Click here Q90 An user has to setup an Auto Scaling group. Due to some issue the group has to failed for launch a single instance for the more than 24 hours.
