Answer 14

Security Groups

Question 15

Through this usage, we can ensure a properly secure encrypted session, save the public key to your EC2 server, and save its private half to your local machine

Answer 15

Key Pair

Question 16

The named document contains the preselected information you proved when manually provisioning an instance, and it cannot be changed once it is deployed.

Answer 16

Launch Configurations

Question 17

The named document contains the preselected information you proved when manually provisioning an instance, allowing versatility to be changed through versioning once deployed.

Answer 17

Launch Templates

Question 18

Detects problems related to the host instance, such as memory exhaustion, file corruption, network configuration errors, or startup configuration problems.

Answer 18

Health Checks

Question 19

Metric that ensures that healthy instances never go below this number. Setting a metric of ‘0’ will remove instances

Answer 19

Scaling Policy Minimum

Question 20

By utilizing a launch configuration, we have the ability to establish a group of instances that will continuously uphold the specific number of instances for an indefinite period.

Answer 20

Auto Scaling Groups

Question 21

The metric ensures that the number of healthy instances does not exceed a certain threshold. It involves setting an expected amount to maintain within the budget.

Answer 21

Scaling Policy Maximum

Question 22

Optional configuration to maintain a desired number of instances. AWS aims to maintain this threshold in case instances fail.

Answer 22

Scaling Policy Desired Capacity

Question 23

Monitor a specific metric in real-time. If this metric surpasses the predefined threshold, the autoscaling feature will automatically adjust the desired capacity while accounting for the cool-down period.

Answer 23

Simple scaling policy

Question 24

Even if the cloud watch metric violates the cloud watch policy, we will wait 5 minutes before implementing another simple scaling policy.

Answer 24

Cool-down period

Question 25

An advanced technique for adding instances based on specific metrics and parameters enables precise and detailed addition and adjustments of instances.

Answer 25

Step Scaling policy (upper/lower bounds)

Question 26

Track a particular metric in real time. If this metric exceeds the predetermined threshold, the autoscaling feature will automatically modify the desired capacity. It will also scale in and remove instances if the metric decreases to maintain the desired capacity.

Answer 26

Target tracking policy

Question 27

Proactively ensure that enough instances are provided before the demand hits for predetermined workload patterns.

Answer 27

Scheduled scaling policy
