Question : A user is trying to understand the ACL and policy for an S bucket. Which of the below mentioned policy permissions is equivalent to the WRITE ACL on a bucket? 1. s3:GetObjectAcl 2. s3:GetObjectVersion 3. Access Mostly Uused Products by 50000+ Subscribers 4. s3:DeleteObject
Explanation: Amazon S3 provides a set of operations to work with the Amazon S3 resources. Each AWS S3 bucket can have an ACL (Access Control List. or bucket policy associated with it. The WRITE ACL list allows the other AWS accounts to write/modify to that bucket. The equivalent S3 bucket policy permission for it is s3:DeleteObject.
Question : A user has created an ELB with Auto Scaling. Which of the below mentioned offerings from ELB helps the user to stop sending new requests traffic from the load balancer to the EC2 instance when the instance is being deregistered while continuing in-flight requests? 1. ELB sticky session 2. ELB deregistration check 3. Access Mostly Uused Products by 50000+ Subscribers 4. ELB auto registration Off Ans : 3 Exp : 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.
Question : A user has launched an EC instance from an instance store backed AMI. The infrastructure team wants to create an AMI from the running instance. Which of the below mentioned steps will not be performed while creating the AMI? 1. Define the AMI launch permissions 2. Upload the bundled volume 3. Access Mostly Uused Products by 50000+ Subscribers 4. Bundle the volume Ans : 1 Exp : When the user has launched an EC2 instance from an instance store backed AMI, it will need to follow certain steps, such as "Bundling the root volume", "Uploading the bundled volume" and "Register the AMI". Once the AMI is created the user can setup the launch permission. However, it is not required to setup during the launch.
Question : You are managing the AWS account of a big organization. The organization has more than + employees and they want to provide access to the various services to most of the employees. Which of the below mentioned options is the best possible solution in this case? 1. The user should create a separate IAM user for each employee and provide access to them as per the policy 2. The user should create an IAM role and attach STS with the role. The user should attach that role to the EC2 instance and setup AWS authentication on that server 3. Access Mostly Uused Products by 50000+ Subscribers group for better access control 4. Attach an IAM role with the organization's authentication service to authorize each user for various AWS services Ans : 4 Exp : AWS Identity and Access Management is a web service which allows organizations to manage users and user permissions for various AWS services. The user is managing an AWS account for an organization that already has an identity system, such as the login system for the corporate network (SSO.. In this case, instead of creating individual IAM users or groups for each user who need AWS access, it may be more practical to use a proxy server to translate the user identities from the organization network into the temporary AWS security credentials. This proxy server will attach an IAM role to the user after authentication.
Question : A user has configured a VPC with a new subnet. The user has created a security group. The user wants to configure that instances of the same subnet communicate with each other. How can the user configure this with the security group? 1. There is no need for a security group modification as all the instances can communicate with each other inside the same subnet 2. Configure the subnet as the source in the security group and allow traffic on all the protocols and ports 3. Access Mostly Uused Products by 50000+ Subscribers 4. The user has to use VPC peering to configure this
Ans : 3 Exp : A Virtual Private Cloud (VPC. is a virtual network dedicated to the user's AWS account. AWS provides two features that the user can use to increase security in VPC: security groups and network ACLs. Security groups work at the instance level. If the user is using the default security group it will have a rule which allows the instances to communicate with other. For a new security group the user has to specify the rule, add it to define the source as the security group itself, and select all the protocols and ports for that source.
Question : A user is launching an instance. He is on the "Tag the instance" screen. Which of the below mentioned information will not help the user understand the functionality of an AWS tag? 1. Each tag will have a key and value 2. The user can apply tags to the S3 bucket 3. Access Mostly Uused Products by 50000+ Subscribers 4. AWS tags are used to find the cost distribution of various resources Ans : 3 Exp : AWS provides cost allocation tags to categorize and track the AWS costs. When the user applies tags to his AWS resources, AWS generates a cost allocation report as a comma-separated value (CSV file. with the usage and costs aggregated by those tags. Each tag will have a key-value and can be applied to services, such as EC2, S3, RDS, EMR, etc. The maximum size of a tag key is 128 unicode characters.
Question : A user has created a VPC with CIDR .../. The user has created public and VPN only subnets along with hardware VPN access to connect to the user's datacenter. The user wants to make so that all traffic coming to the public subnet follows the organization's proxy policy. How can the user make this happen? 1. Setting up a NAT with the proxy protocol and configure that the public subnet receives traffic from NAT 2. Settin up a proxy policy in the internet gateway connected with the public subnet 3. Access Mostly Uused Products by 50000+ Subscribers 4. Setting the route table and security group of the public subnet which receives traffic from a virtual private gateway
Ans : 4 Exp : The user can create subnets within a VPC. If the user wants to connect to VPC from his own data centre, he can setup public and VPN only subnets which uses hardware VPN access to connect with his data centre. When the user has configured this setup, it will update the main route table used with the VPN-only subnet, create a custom route table and associate it with the public subnet. It also creates an internet gateway for the public subnet. By default the internet traffic of the VPN subnet is routed to a virtual private gateway while the internet traffic of the public subnet is routed through the internet gateway. The user can set up the route and security group rules. These rules enable the traffic to come from the organization's network over the virtual private gateway to the public subnet to allow proxy settings on that public subnet.
Question A user has created a VPC with CIDR .../. The user has created a public subnet with CIDR .../ and a private subnet with CIDR 20.0.0.128/25. The user has launched one instance each in the private and public subnets. Which of the below mentioned options cannot be the correct IP address (private IP. assigned to an instance in the public or private subnet? 1. 20.0.0.255 2. 20.0.0.132 3. Access Mostly Uused Products by 50000+ Subscribers 4. 20.0.0.55
Explanation: When the user creates a subnet in VPC, he specifies the CIDR block for the subnet. In this case the user has created a VPC with the CIDR block 20.0.0.0/24, which supports 256 IP addresses (20.0.0.0 to 20.0.0.255.. The public subnet will have IP addresses between 20.0.0.0 - 20.0.0.127 and the private subnet will have IP addresses between 20.0.0.128 - 20.0.0.255. AWS reserves the first four IP addresses and the last IP address in each subnet's CIDR block. These are not available for the user to use. Thus, the instance cannot have an IP address of 20.0.0.255
Question : A user has launched an EBS backed EC instance. The user has rebooted the instance. Which of the below mentioned statements is not true with respect to the reboot action? 1. The private and public address remains the same 2. The Elastic IP remains associated with the instance 3. Access Mostly Uused Products by 50000+ Subscribers 4. The instance runs on a new host computer Ans : 4 Exp : 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.
Question : A user has setup a web application on EC. The user is generating a log of the application performance at every second. There are multiple entries for each second. If the user wants to send that data to CloudWatch every minute, what should he do? 1. The user should send only the data of the 60th second as CloudWatch will map the receive data timezone with the sent data timezone 2. It is not possible to send the custom metric to CloudWatch every minute 3. Access Mostly Uused Products by 50000+ Subscribers 4. Calculate the average of one minute and send the data to CloudWatch Ans : 3 Exp : Amazon CloudWatch aggregates statistics according to the period length that the user has specified while getting data from CloudWatch. The user can publish as many data points as he wants with the same or similartime stamps. CloudWatch aggregates them by the period length when the user calls get statistics about those data points. CloudWatch records the average (sum of all items divided by the number of items. of the values received for every 1-minute period, as well as the number of samples, maximum value, and minimum value for the same time period. CloudWatch will aggregate all the data which have time stamps within a one-minute period.
Question : An AWS root account owner is trying to create a policy to access RDS. Which of the below mentioned statements is true with respect to the above information? 1. Create a policy which allows the users to access RDS and apply it to the RDS instances 2. The user cannot access the RDS database if he is not assigned the correct IAM policy 3. Access Mostly Uused Products by 50000+ Subscribers 4. The policy should be created for the user and provide access for RDS Ans : 3 Exp : AWS Identity and Access Management is a web service which allows organizations to manage users and user permissions for various AWS services. If the account owner wants to create a policy for RDS, the owner has to create an IAM user and define the policy which entitles the IAM user with various RDS services such as Launch Instance, Manage security group, Manage parameter group etc.
Question : A user is using a small MySQL RDS DB. The user is experiencing high latency due to the Multi AZ feature.Which of the below mentioned options may not help the user in this situation? 1. Schedule the automated back up in non-working hours 2. Use a large or higher size instance 3. Access Mostly Uused Products by 50000+ Subscribers 4. Take a snapshot from standby Replica
Explanation: An RDS DB instance which has enabled Multi AZ deployments may experience increased write and commit latency compared to a Single AZ deployment, due to synchronous data replication. The user may also face changes in latency if deployment fails over to the standby replica. For production workloads, AWS recommends the user to use provisioned IOPS and DB instance classes (m1.large and larger. as they are optimized for provisioned IOPS to give a fast, and consistent performance. With Multi AZ feature, the user can not have option to take snapshot from replica.
1. As he is not an owner, he can not delete the object from bucket. 2. He can do all the operations on the bucket 3. Access Mostly Uused Products by 50000+ Subscribers 4. The IAM user can perform all operations on the bucket using only API/SDK
