NO.1 A sys admin is trying to understand the sticky session algorithm. Please select the correct
sequence of steps, both when the cookie is present and when it is not, to help the admin understand
the implementation of the sticky session:
ELB inserts the cookie in the response ELB chooses the instance based on the load balancing
algorithm Check the cookie in the service request The cookie is found in the request The cookie is not
found in the request
A. 3,1,4,2 [Cookie is not Present] & 3,1,5,2 [Cookie is Present]
B. 3,4,1,2 [Cookie is not Present] & 3,5,1,2 [Cookie is Present]
C. 3,5,2,1 [Cookie is not Present] & 3,4,2,1 [Cookie is Present]
D. 3,2,5,4 [Cookie is not Present] & 3,2,4,5 [Cookie is Present]
Answer: C

Explanation:
Generally AWS ELB routes each request to a zone with the minimum load. The Elastic Load Balancer
provides a feature called sticky session which binds the user's session with a specific EC2 instance.
The load balancer uses a special load-balancer-generated cookie to track the application instance for
each request. When the load balancer receives a request, it first checks to see if this cookie is present
in the request. If so, the request is sent to the application instance specified in the cookie. If there is
no cookie, the load balancer chooses an application instance based on the existing load balancing
algorithm. A cookie is inserted into the response for binding subsequent requests from the same user
to that application instance.

NO.2 A user has launched an EBS backed EC2 instance. The user has rebooted the instance. Which
of the below mentioned statements is not true with respect to the reboot action?
A. The private and public address remains the same
B. The Elastic IP remains associated with the instance
C. The volume is preserved
D. The instance runs on a new host computer
Answer: D

Amazon日記   AWS-SysOps   AWS-SysOps対象者   AWS-SysOps
Explanation:
A user can reboot an EC2 instance using the AWS console, the Amazon EC2 CLI or the Amazon EC2
API. Rebooting an instance is equivalent to rebooting an operating system. However, it is
recommended that the user use the Amazon EC2 to reboot the instance instead of running the
operating system reboot command from the instance. The instance remains on the same host
computer and maintains its public DNS name, private IP address, and any data on its instance store
volumes. It typically takes a few minutes for the reboot to complete, but the time it takes to reboot
depends on the instance configuration.

NO.3 You are using ElastiCache Memcached to store session state and cache database queries in your

A. Increase the number of nodes in your cluster
B. Tweak the max-item-size parameter
C. Shrink the number of nodes in your cluster
D. Increase the size of the nodes in the duster

NO.4 A user has setup connection draining with ELB to allow in-flight requests to continue while the
instance is being deregistered through Auto Scaling. If the user has not specified the draining time,
how long will ELB allow inflight requests traffic to continue?
A. 600 seconds
B. 3600 seconds
C. 300 seconds
D. 0 seconds
Answer: C

Amazon日本語   AWS-SysOps資格トレーニング   AWS-SysOps   AWS-SysOps参考書   AWS-SysOps試験スクール   AWS-SysOps学習
Explanation:
The Elastic Load Balancer connection draining feature causes the load balancer to stop sending new
requests to the back-end instances when the instances are deregistering or become unhealthy, while
ensuring that inflight requests continue to be served. The user can specify a maximum time (3600
seconds. for the load balancer to keep the connections alive before reporting the instance as
deregistered. If the user does not specify the maximum timeout period, by default, the load balancer
will close the connections to the deregistering instance after 300 seconds.

NO.5 Your application currently leverages AWS Auto Scaling to grow and shrink as load Increases'
decreases and has been performing well Your marketing team expects a steady ramp up in traffic to
follow an upcoming campaign that will result in a 20x growth in traffic over 4 weeks Your forecast for
the approximate number of Amazon EC2 instances necessary to meet the peak demand is 175.
What should you do to avoid potential service disruptions during the ramp up in traffic?
A. Ensure that you have pre-allocated 175 Elastic IP addresses so that each server will be able to
obtain one as it launches
B. Check the service limits in Trusted Advisor and adjust as necessary so the forecasted count remains
within limits.
C. Change your Auto Scaling configuration to set a desired capacity of 175 prior to the launch of the
marketing campaign
D. Pre-warm your Elastic Load Balancer to match the requests per second anticipated during peak
demand prior to the marketing campaign

NO.7 Your entire AWS infrastructure lives inside of one Amazon VPC You have an Infrastructure
monitoring application running on an Amazon instance in Availability Zone (AZ) A of the region, and
another application instance running in AZ B.
The monitoring application needs to make use of ICMP ping to confirm network reachability of the
instance hosting the application.
Can you configure the security groups for these instances to only allow the ICMP ping to pass from
the monitoringinstance to the application instance and nothing else'' If so how?
A. No Two instances in two different AZ's can't talk directly to each other via ICMP ping as that
protocol is not allowed across subnet (iebroadcast) boundaries
B. Yes Both the monitoring instance and the application instance have to be a part of the same
security group, and that security group needs to allow inbound ICMP
C. Yes, The security group for the monitoring instance needs to allow outbound ICMP and the
application instance's security group needs to allow Inbound ICMP
D. Yes, Both the monitoring instance's security group and the application instance's security group
need to allow both inbound and outbound ICMP ping packets since ICMP is not a connection-
oriented protocol
Answer: A

NO.8 A user is trying to delete an Auto Scaling group from CLI. Which of the below mentioned steps
are to be performed by the user?
A. Terminate the instances with the ec2-terminate-instance command
B. Terminate the Auto Scaling instances with the as-terminate-instance command
C. Set the minimum size and desired capacity to 0
D. There is no need to change the capacity. Run the as-delete-group command and it will reset all
values to 0
Answer: C

Amazon参考書勉強   AWS-SysOps購入   AWS-SysOps日本語サンプル   AWS-SysOps対応
Explanation:
If the user wants to delete the Auto Scaling group, the user should manually set the values of the
minimum and desired capacity to 0. Otherwise Auto Scaling will not allow for the deletion of the
group from CLI. While trying from the AWS console, the user need not set the values to 0 as the Auto
Scaling console will automatically do so.
