Question 6

A user has configured an Auto Scaling group with ELB. The user has enabled detailed CloudWatch monitoring on Auto Scaling. Which of the below mentioned statements will help the user understand the functionality better?
A) It is not possible to setup detailed monitoring for Auto Scaling
B) In this case, Auto Scaling will send data every minute and will charge the user extra
C) Detailed monitoring will send data every minute without additional charges
D) Auto Scaling sends data every minute only and does not charge the user

Accepted Answer

Enabling detailed monitoring for Auto Scaling means that CloudWatch will collect and send metrics every minute, and this incurs additional charges compared to the default 5-minute interval.

Question 7

A user is trying to connect to a running EC2 instance using SSH. However, the user gets a connection time out error. Which of the below mentioned options is not a possible reason for rejection?
A) The access key to connect to the instance is wrong
B) The security group is not configured properly
C) The private key used to launch the instance is not correct
D) The instance CPU is heavily loaded

Accepted Answer

The access key is not used for SSH connections; instead, SSH uses a private key for authentication. Therefore, an incorrect access key is not a reason for a connection timeout error.

Question 8

A user has launched an EBS backed instance. The user started the instance at 9 AM in the morning. Between 9 AM to 10 AM, the user is testing some script. Thus, he stopped the instance twice and restarted it. In the same hour the user rebooted the instance once. For how many instance hours will AWS charge the user?
A) 3 hours
B) 4 hours
C) 2 hours
D) 1 hour

Accepted Answer

AWS charges for instance hours. When an instance is stopped, it is not charged. When an instance is rebooted, it is not charged. So, the user will be charged for 3 instance hours (9 AM to 10 AM).
