AWS Certified SysOps Administrator - Associate Questions and Answers (Dumps and Practice Questions)
Question : A sys admin is using server side encryption with AWS S. Which of the below mentioned statements helps the user understand the S encryption
functionality?
1. The server side encryption with the user supplied key works when versioning is enabled
2. The user can use the AWS console, SDK and APIs to encrypt or decrypt the content for server side
encryption with the user supplied key
3. Access Mostly Uused Products by 50000+ Subscribers
4. The user can upload his own encryption key to the S3 console
Correct Answer : Get Lastest Questions and Answer :
Exp: AWS S3 supports client side or server side encryption to encrypt all data at rest. The server side encryption can either have the S3 supplied
AES-256 encryption key or the user can send the key along with each API call to supply his own encryption key. The encryption with the user
supplied key (SSE-C. does not work with the AWS console. The S3 does not store the keys and the user has to send a key with each request. The
SSE-C works when the user has enabled versioning.

4. Canonical user group
Correct Answer : Get Lastest Questions and Answer :
Exp: An S3 bucket ACL grantee can be an AWS account or one of the predefined Amazon S3 groups. Amazon S3 has a set of predefined groups.
When granting account access to a group, the user can specify one of the URLs of that group instead of a canonical user ID. AWS S3 has the
following predefined groups:
Authenticated Users group: It represents all AWS accounts. All Users group: Access permission to this group allows anyone to access the
resource. Log Delivery group: WRITE permission on a bucket enables this group to write server access logs to the bucket.
Question : A user has created a VPC with CIDR .../ using the wizard. The user has created a public subnet CIDR .../. and VPN only
subnets CIDR 20.0.1.0/24. along with the VPN gateway vgw-12345. to connect to the user's data centre. The user's data centre has CIDR
172.28.0.0/12. The user has also setup a NAT instance i-123456. to allow traffic to the internet from the VPN subnet. Which of the below
mentioned options is not a valid entry for the main route table in this scenario?
1. Destination: 20.0.1.0/24 and Target: i-12345
2. Destination: 0.0.0.0/0 and Target: i-12345
3. Access Mostly Uused Products by 50000+ Subscribers
4. Destination: 20.0.0.0/16 and Target: local
Correct Answer : Get Lastest Questions and Answer :
Exp: The user can create subnets as per the requirement within a VPC. If the user wants to connect VPC from his own data centre, he can setup a
public and VPN only subnet which uses hardware VPN access to connect with his data centre. When the user has configured this setup with
Wizard, it will create a virtual private gateway to route all traffic of the VPN subnet. If the user has setup a NAT instance to route all the internet
requests then all requests to the internet should be routed to it. All requests to the organization's DC will be routed to the VPN gateway. Here are
the valid entries for the main route table in this scenario:
Destination: 0.0.0.0/0 & Target: i-12345 (To route all internet traffic to the NAT Instance.
Destination: 172.28.0.0/12 & Target: vgw-12345 (To route all the organization's data centre traffic to the VPN gateway.
Destination: 20.0.0.0/16 & Target: (To allow local routing in VPC.

Question : An organization has setup Auto Scaling with ELB. Due to some manual error, one of the instances got
rebooted. Thus, it failed the Auto Scaling health check. Auto Scaling has marked it for replacement. How can the system admin ensure that the
instance does not get terminated?
1. Update the Auto Scaling group to ignore the instance reboot event
2. It is not possible to change the status once it is marked for replacement
3. Access Mostly Uused Products by 50000+ Subscribers
4. Change the health of the instance to healthy using the Auto Scaling commands
Ans : 4
Exp : After an instance has been marked unhealthy by Auto Scaling, as a result of an Amazon EC2 or ELB health check, it is almost immediately
scheduled for replacement as it will never automatically recover its health. If the user knows that the instance is healthy then he can manually call
the SetInstanceHealth action (or the as-setinstance- health command from CLI. to set the instance's health status back to healthy. Auto Scaling
will throw an error if the instance is already terminating or else it will mark it healthy.

Question : A user is planning to scale up an application by AM and scale down by PM daily using Auto Scaling. What should the user do in this case?
1. Setup the scaling policy to scale up and down based on the CloudWatch alarms
2. The user should increase the desired capacity at 8 AM and decrease it by 7 PM manually
3. Access Mostly Uused Products by 50000+ Subscribers
4. Setup scheduled actions to scale up or down at a specific time
Ans : 1
Exp : Auto Scaling based on a schedule allows the user to scale the application in response to predictable load
changes. To configure the Auto Scaling group to scale based on a schedule, the user needs to create
scheduled actions. A scheduled action tells Auto Scaling to perform a scaling action at a certain time in the future.
Question : A user has created a VPC with two subnets: one public and one private. The user is planning to run the patch update for the instances in the
private subnet. How can the instances in the private subnet connect to theinternet?
1. Use the internet gateway with a private IP
2. Allow outbound traffic in the security group for port 80 to allow internet updates
3. Access Mostly Uused Products by 50000+ Subscribers
4. Use NAT with an elastic IP
Ans : 4
Exp : A Virtual Private Cloud (VPC. is a virtual network dedicated to the user's AWS account. A user can create a subnet with VPC and launch instances
inside that subnet. If the user has created two subnets (one private and one public., he would need a Network Address Translation (NAT. instance
with the elastic IP address. This enables the instances in the private subnet to send requests to the internet (for example, to perform software
updates..
Question : A user has configured an EC instance in the US-East-a zone. The user has enabled detailed monitoring of the instance. The user is trying to get

2. monitoring.us-east-1-a.amazonaws.com
3. Access Mostly Uused Products by 50000+ Subscribers
4. cloudwatch.us-east-1a.amazonaws.com
Ans 1

Question : A user has configured ELB with Auto Scaling. The user suspended the Auto Scaling AddToLoadBalancer
(which adds instances to the load balancer. process for a while. What will happen to the instances launched during the suspension period?
1. The instances will not be registered with ELB and the user has to manually register when the process is resumed
2. The instances will be registered with ELB only once the process has resumed
3. Access Mostly Uused Products by 50000+ Subscribers
4. It is not possible to suspend only the AddToLoadBalancer process
Ans : 1
Exp : Auto Scaling performs various processes, such as Launch, Terminate, add to Load Balancer etc. The user can also suspend the individual
process. The AddToLoadBalancer process type adds instances to the load balancer when the instances are launched. If this process is
suspended, Auto Scaling will launch the instances but will not add them to the load balancer. When the user resumes this process, Auto Scaling
will resume adding new instances launched after resumption to the load balancer. However, it will not add running instances that were launched
while the process was suspended; those instances must be added manually.

such as client IP, request path, ELB IP, time, and latencies. The time will have information, such as Request Processing time, Backend
Processing time and Response Processing time.
