Q171. You've been brought in as solutions architect to assist an enterprise customer with their migration of an e-commerce platform to Amazon Virtual Private Cloud (VPC) The previous architect has already deployed a 3-tier VPC, The configuration is as follows:
VPC: vpc-2f8bc447 IGW: igw-2d8bc445 NACL: ad-208bc448
5ubnets and Route Tables: Web sewers: subnet-258bc44d
Application servers: subnet-248bc44c Database sewers: subnet-9189c6f9 Route Tables:
rrb-218bc449 rtb-238bc44b Associations:
subnet-258bc44d : rtb-218bc449 subnet-248bc44c : rtb-238bc44b subnet-9189c6f9 : rtb-238bc44b
You are now ready to begin deploying EC2 instances into the VPC Web servers must have direct access to the internet Application and database sewers cannot have direct access to the internet.
Which configuration below will allow you the ability to remotely administer your application and database servers, as well as allow these sewers to retrieve updates from the Internet?
A. Create a bastion and NAT instance in subnet-258bc44d, and add a route from rtb- 238bc44b to the NAT instance.
B. Add a route from rtb-238bc44b to igw-2d8bc445 and add a bastion and NAT instance within subnet-248bc44c.
C. Create a bastion and NAT instance in subnet-248bc44c, and add a route from rtb- 238bc44b to subneb258bc44d.
D. Create a bastion and NAT instance in subnet-258bc44d, add a route from rtb-238bc44b to Igw- 2d8bc445, and a new NACL that allows access between subnet-258bc44d and subnet -248bc44c.
Answer: A
Q172. A user has created photo editing software and hosted it on EC2. The software accepts requests from the user about the photo format and resolution and sends a message to S3 to enhance the picture accordingly. Which of the below mentioned AWS services will help make a scalable software with the AWS infrastructure in this scenario?
A. AWS Simple Notification Service
B. AWS Simple Queue Service
C. AWS Elastic Transcoder
D. AWS Glacier
Answer: B
Explanation:
Amazon Simple Queue Service (SQS) is a fast, reliable, scalable, and fully managed message queuing service. SQS provides a simple and cost-effective way to decouple the components of an application. The user can configure SQS, which will decouple the call between the EC2 application and S3. Thus, the application does not keep waiting for S3 to provide the data.

Q173. You decide that you need to create a number of Auto Scaling groups to try and save some money as you have noticed that at certain times most of your EC2 instances are not being used. By default, what is the maximum number of Auto Scaling groups that AWS will allow you to create?
A. 12
B. Unlimited
C. 20
D. 2
Answer: C
Explanation:
Auto Scaling is an AWS service that allows you to increase or decrease the number of EC2 instances within your appIication's architecture. With Auto Scaling, you create collections of EC2 instances, called Auto Scaling groups. You can create these groups from scratch, or from existing EC2 instances that are already in production.

Q174. A web design company currently runs several FTP servers that their 250 customers use to upload and download large graphic files They wish to move this system to AWS to make it more scalable, but they wish to maintain customer privacy and Keep costs to a minimum.
What AWS architecture would you recommend?
A. ASK their customers to use an 53 client instead of an FTP client. Create a single 53 bucket Create an IAM user for each customer Put the IAM Users in a Group that has an IAM policy that permits access to sub-directories within the bucket via use of the 'username' Policy variable.
B. Create a single 53 bucket with Reduced Redundancy Storage turned on and ask their customers to use an 53 client instead of an FTP client Create a bucket for each customer with a Bucket Policy that permits access only to that one customer.
C. Create an auto-scaling group of FTP servers with a scaling policy to automatically scale-in when minimum network traffic on the auto-scaling group is below a given threshold. Load a central list of ftp users from 53 as part of the user Data startup script on each Instance.
D. Create a single 53 bucket with Requester Pays turned on and ask their customers to use an 53 client instead of an FTP client Create a bucket tor each customer with a Bucket Policy that permits access only to that one customer.
Answer: A
Q175. An administrator is using Amazon CIoudFormation to deploy a three tier web application that consists of a web tier and application tier that will utilize Amazon DynamoDB for storage when creating the CIoudFormation template which of the following would allow the application instance access to the DynamoDB tables without exposing API credentials?
A. Create an Identity and Access Management Role that has the required permissions to read and write from the required DynamoDB table and associate the Role to the application instances by referencing an instance profile.
B. Use the Parameter section in the Cloud Formation template to nave the user input Access and Secret Keys from an already created IAM user that has me permissions required to read and write from the required DynamoDB table.
C. Create an Identity and Access Management Role that has the required permissions to read and write from the required DynamoDB table and reference the Role in the instance profile property of the application instance.
D. Create an identity and Access Management user in the CIoudFormation template that has permissions to read and write from the required DynamoDB table, use the GetAtt function to retrieve the Access and secret keys and pass them to the application instance through user-data.
Answer: C
Q176. You need to set up a security certificate for a cIient's e-commerce website as it will use the HTTPS protocol. Which of the below AWS services do you need to access to manage your SSL server certificate?
A. AWS Directory Service
B. AWS Identity & Access Management
C. AWS CIoudFormation
D. Amazon Route 53
Answer: B
Explanation:
AWS Identity and Access Management (IAM) is a web service that enables Amazon Web Services (AWS) customers to manage users and user permissions in AWS.
All your SSL server certificates are managed by AWS Identity and Access management (IAM). Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/ManagingServerCerts.htm|
Q177. Your system recently experienced down time during the troubleshooting process. You found that a new administrator mistakenly terminated several production EC2 instances.
Which of the following strategies will help prevent a similar situation in the future? The administrator still must be able to:
- launch, start stop, and terminate development resources.
- launch and start production instances.
A. Create an IAM user, which is not allowed to terminate instances by leveraging production EC2 termination protection.
B. Leverage resource based tagging along with an IAM user, which can prevent specific users from terminating production EC2 resources.
C. Leverage EC2 termination protection and multi-factor authentication, which together require users to authenticate before terminating EC2 instances
D. Create an IAM user and apply an IAM role which prevents users from terminating production EC2 instances.
Answer: B
Explanation:
Working with volumes
When an API action requires a caller to specify multiple resources, you must create a policy statement that allows users to access all required resources. If you need to use a Condition element with one or more of these resources, you must create multiple statements as shown in this example.
The following policy allows users to attach volumes with the tag "volume_user=iam-user-name" to instances with the tag "department=dev", and to detach those volumes from those instances. If you attach this policy to an IAM group, the aws:username policy variable gives each IAM user in the group permission to attach or detach volumes from the instances with a tag named voIume_ user that has his or her IAM user name as a value.

"ec2:ResourceTag/voIume_user": "${aws:username}" I
I I I I
Launching instances (Runlnstances)
The Runlnstances API action launches one or more instances. Runlnstances requires an AM and creates an instance; and users can specify a key pair and security group in the request. Launching into EC2-VPC requires a subnet, and creates a network interface. Launching from an Amazon EBS-backed AM creates a volume. Therefore, the user must have permission to use these Amazon EC2 resources. The caller can also configure the instance using optional parameters to Run Instances, such as the instance type and a subnet. You can create a policy statement that requires users to specify an optional parameter, or restricts users to particular values for a parameter. The examples in this section demonstrate some of the many possible ways that you can control the configuration of an instance that a user can launch.
Note that by default, users don't have permission to describe, start, stop, or terminate the resulting instances. One way to grant the users permission to manage the resulting instances is to create a specific tag for each instance, and then create a statement that enables them to manage instances with that tag. For more information, see 2: Working with instances.
a. AMI
The following policy allows users to launch instances using only the AM|s that have the specified tag, "department=dev", associated with them. The users can't launch instances using other ANI Is because the Condition element of the first statement requires that users specify an AM that has this tag. The users also can't launch into a subnet, as the policy does not grant permissions for the subnet and network interface resources. They can, however, launch into EC2-Ciassic. The second statement uses a wildcard to enable users to create instance resources, and requires users to specify the key pair
project_keypair and the security group sg-1a2b3c4d. Users are still able to launch instances without a key pair.
{
"Version": "2012-10-I7",
"Statement": [{ I,
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region::image/ami-*" I,
"Condition": { "StringEqua|s": {
"ec2:ResourceTag/department": "dev" I
I I,
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:voIume/*",
"arn:aws:ec2:region:account:key-pair/project_keypair",
"arn :aws :ec2: region: account:security-group/sg-1a 2b3c4d" I
I
}
Alternatively, the following policy allows users to launch instances using only the specified AMIs, ami-9e1670f7 and ami-45cf5c3c. The users can't launch an instance using other AMIs (unless another statement grants the users permission to do so), and the users can't launch an instance into a subnet.
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [
"arn:aws:ec2:region::image/ami-9e1670f7", "arn:aws:ec2:region::image/ami-45cf5c3c", "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:voIume/*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
}
}
Alternatively, the following policy allows users to launch instances from all AMs owned by Amazon. The Condition element of the first statement tests whether ec2:0wner is amazon. The users can't launch an instance using other AM Is (unless another statement grants the users permission to do so).
The users are able to launch an instance into a subnet. "Version": "2012-10-17",
"Statement": [{
"Effect": "A| low",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region::image/ami-*" l,
"Condition": { "StringEqua|s": { "ec2:0wner": "amazon"
}
},
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource" : [ "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:subnet/*", "arn:aws:ec2:region:account:voIume/*",
"arn:aws:ec2:region:account:network-interface/*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
I
} I
}
b. Instance type
The following policy allows users to launch instances using only the t2.micro or t2.sma|I instance type, which you might do to control costs. The users can't launch larger instances because the Condition element of the first statement tests whether ec2:1nstanceType is either t2.micro or t2.smaII.
{
"Version": "2012-10-I7",
"Statement": [{
"Effect": "A| low",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region:account:instance/*" I,
"Condition": { "StringEqua|s": {
"ec2:1nstanceType": ["t2.micro", "t2.smaII"]
}
}
},
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region::image/ami-*", "arn:aws:ec2:region:account:subnet/*",
"arn:aws:ec2:region:account:network-interface/*", "arn:aws:ec2:region:account:voIume/*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
I
} I
}
Alternatively, you can create a policy that denies users permission to launch any instances except t2.micro and t2.sma|I instance types.
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Deny",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region:account:instance/*" l,
"Condition": { "StringNotEqua|s": {
"ec2:1nstanceType": ["t2.micro", "t2.smaII"]
}
}
},
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region::image/ami-*",
"arn:aws:ec2:region:account:network-interface/* "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:subnet/*", "arn:aws:ec2:region:account:voIume/*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
}
}
c. Subnet
The following policy allows users to launch instances using only the specified subnet, subnet-12345678. The group can't launch instances into any another subnet (unless another statement grants the users permission to do so). Users are still able to launch instances into EC2-Ciassic.
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [
"arn :aws :ec2: region:account:subnet/subnet-123456 78",
"arn:aws:ec2:region:account:network-interface/*", "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:voIume/*", "arn:aws:ec2:region::image/ami-*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
}
}
Alternatively, you could create a policy that denies users permission to launch an instance into any other subnet. The statement does this by denying permission to create a network interface, except where subnet subnet-12345678 is specified. This denial overrides any other policies that are created to allow launching instances into other subnets. Users are still able to launch instances into EC2-Classic.
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Deny",
"Action": "ec2:RunInstances", "Resource": [
"arn:aws:ec2:region:account:network-interface/*" l,
"Condition": { "ArnNotEquaIs": {
"ec2:Subnet": "arn :aws:ec2:region:account:subnet/subnet-12345678"
}
}
},
{
"Effect": "A||ow",
"Action": "ec2:RunInstances", "Resource": [ "arn:aws:ec2:region::image/ami-*",
"arn:aws:ec2:region:account:network-interface/*", "arn:aws:ec2:region:account:instance/*", "arn:aws:ec2:region:account:subnet/*", "arn:aws:ec2:region:account:voIume/*", "arn:aws:ec2:region:account:key-pair/*", "arn:aws:ec2:region:account:security-group/*"
}
}
