LinkedIn Amazon Web Services Exam Quiz Answers

  • In the VPC dashboard, click Elastic IPs. Select the Elastic IP and click Associate Address. Select each EC2 instance you wish to assign this address to.
  • In the EC2 dashboard, click on EC2 instance. Under Actions, select networking > Manage IP Addresses. click to add a new IP address and type in the address of the Elastic IP. Repeat the process for each EC2 instance you want to assign this Elastic IP to.
  • Use the AWS CLI and pass in several ‘–instance-id’ options to hte aws ec2 assosiate-address command.
  • An elastic IP cannot be assigned to multiple EC2 instances. It can only be assosiated to a single EC2 instance.
  • You cannot recover access to your AWS root account. Contact AWS support.
  • An email will be sent to the email address on file to verify ownership of the account. You will then need to provide the phone number on the account.
  • An email will be sent to the email address on file. After clicking in the link in your email, provide one of the MFA recovery codes that were created when MFA was enabled.
  • Use the AWS CLI with the root account access token to disable MFA on the root account. Then use the CLI to set a new password on the root account.
  • Close all existing connections to the SQL Server database and use Database Migration Service to transfer the data to RDS.
  • Use Database Migration Service to replicate the database to RDS and keep it in sync during the migration. Repoint your applications to use the new RDS endpoint.
  • Detach the SQL Server database during the migration. Take a backup of the database and use SQ with Accelerated Transfer to upload the backups to S3. Restore the backups to the RDS instance.
  • Use the Import and Export wizard within SQL Server Enterprise Manager to create an export task and export the tables to the RDS instance.
  • Establish a connection between your two data centers and connect the second data center to the first through a private tunnel. Traffic will flow from the second data center and then through the first data, and then into AWS.
  • Create a second customer gateway and configure your VPN client at your second data center to connect to the virtual private gateway.
  • Create a second virtual private gateway (VPG) and attach it to the VPC. Create a customer gateway for the new virtual private gateway and use your VPN client at your second data center to establish a connection to the VPG.
  • You cannot have more than one customer gateway per VPC, so the proposed solution will not work. Create a second VPC with a virtual private gateway and a customer gateway. Bridge the two VPCs using VPC peering.
  • Stop the instance and create an AMI image. Launch the image using a new key pair.
  • Contact AWS support. A support specialist can remotely restore access to your instance and send you a new key pair.
  • You cannot connect to this EC2 instance. The key pair is displayed only one time. If you lose it, you have lost all access to this instance. Connect the EBS volume to another instance to recover your files.
  • Attach the EBS volume to a temporary instance launched with a new key pair, and overwrite ~/.ssh.authorized_keys using the same file from the new instance.
  • Replicate your infrastructure across two regions. You will harden the application to a regional failure and you will double your capacity.
  • Take an AMI image of a front-end server to save your configuration and then add more servers to your cluster pror to the conference. Remove the servers from the cluster after the spike from the conference.
  • Test to determine your throughput and how many users you can support. Develop a scaling plan for your front end, microservices, and database based on CloudWatch metrics that align with the tested bottlenecks.
  • Use Auto Scaling groups to create more front-end servers when the CloudWatch metrics for CPU usage on a single instance rise above 80% for five minutes.
  • Use Route 53 with geolocation lookups to direct traffic between the two regions.
  • Create a WAF redirection rule that redirects traffic at the EU data center if the source IP comes from certain countries.
  • Purchase a country domain extension and direct your users to the correct site, such as example.com and example.co
  • Have your front-end application test the latency between each data center and use the data center that is responding the fastest.
  • ubuntu
  • system-user
  • ec2-user
  • admin
  • Use a Classic Load Balancer, not Application Load Balancer.
  • Application Load Balancer does not preserve the original source IP address. The analytics software needs to be configured to look at the ‘X-Forwarded-For’ HTTP request header for the correct source IP address.
  • Application Load Balencer has to be configured to retain the source IP address of the traffic it is forwarding. Create a policy that enables ProxyProtocol support and attach it to the ALB using the AWS CLI.
  • Configure the web server EC2 instances to only have private IP addresses. The public IP addresses of the instances are being recorded into the web server logs, bug only ALB should have a public interface and it will route traffic to instances via the private interface.

  • Use the RDS console to force a reboot of the database instance so that the primary server becomes the master server again.
  • The server running the .NET utilities is caching the DNS lookup on the database cluster address. Flush the DNS cache of the server and force the C# utilities to open new connections to the database.
  • A.NET application will retain the IP address of a connection string until the host machine is rebooted.
  • The NET utilities need to change the SQL Server endpoint in the connection strings to read from the secondary database server using a try/catch.

  • Use RDS for SQL Server and create the same instance in two different regions. Use Database Migration Service to keep each database in sync.
  • Use a VPN or VPC peering to establish a connection between the VPCs in each region. Install SQL Server Enterprise Edition on EC2 instances in each region and configure an Always On availability group.
  • Use RDS for SQL Server 2016 or 2017 Enterprise Edition. Enable multi-AZ support and select the Mirroring/Always On option. Select another region for the mirroring option.
  • You cannot set up an active-active architecture for SQL Server that spans geographic regions.
  • All images in the AWS Marketplace incur additional hourly fees in addition to the charges from the instance size you select.
  • You can only launch images that were created by other users on your AWS account, so you pay only for the instance size you select and the S3 storage costs for the base image.
  • Each image has its own pricing that could either be free, or include charges for software licensing costs. You will also pay for the instance the image runs on
  • All images in the AWS Marketplace contain only open-source software with no additional fees and are created by other AWS users. You will pay only for the instance size you select.
  • The instances created by ECS do not have patches that need to be applied; however, you should make sure your containers contain any important security updates.
  • Refresh the cluster with instances built from the latest ECS AMI.
  • ECS clusters do not use EC2 instances.

  • Using the root AWS account, activate IAM access to the billing information for the account. Make sure your IAM users have the Billing FullAccessGroup policy. Then from the billing dashboard, check the accrued charges once a day.
  • If you are using the AWS free tier, you will have to confirm the usage of any service that goes over the AWS free tier limits.
  • Using the root AWS account enable Billing Alerts in the user preferences. Then use CloudWatch to create a billing alarm and set a threshold to a specific dollar amount for your estimated monthly charges.
  • The primary key should be a partition key of the title field.
  • The primary key should be the title field and the partition key should be the genres field.
  • The primary key should be a composite key comprised of a partition key on the title field and a sort key on the year field.
  • The primary key should be created as a completely unique value, such a sequential numerical list of movie IDs. The partition key should be title field for fast lookup.

  • Serverless web applications run within the web browser of the user, so you will need to store any data the user changes directly in a database.
  • Lambda only allows you to write functions in JavaScript.
  • Lambda does not use servers, so it can only return the same request to every user.
  • Lambda is stateless, so it won’t remember who a user is in between requests.
  • CloudTrail
  • CloudFormation
  • AWS Config
  • AWS Service Catalog
  • Check the routing tables for the VPC.
  • Verify that the assigned security groups allow TCP port 1433 traffic from your current IP address.
  • Check the policies within Windows Firewall.
  • Verify that you are connecting to the instance using a user that is not sa.
  • The rule that exposes TCP ports 3380-3390 would also publicly expose port 3389 (RDP) to the entire internet. Write separate rules to only expose the needed ports.
  • The first security group rule allows all traffic into this instance. Exposing your entire instance to the whole internet leaves the server open to various attacks of the other services running on different port numbers.
  • Verify that the AWS account owners actually control the entire CIDR C block for 12.228.11.0-255 and these are secured IPs for RDP access into this instance.
  • There are no recommendations to make.
  • Assign Elastic IPs to all of the instances and create a group that allows all traffic to pass between each of the five Elastic IP addresses and allow all inbound HTTPS traffic.
  • Front-end web servers should allow HTTPS. Assign another group to all of the instances that allows all traffic to pass between instances using that group.
  • Create a security group that allows inbound NFS, HTTP, and HTTPS traffic from all IP addresses. Apply this group to all of the servers.
  • Create a security group that allows inbound HTTP and HTTPS traffic from all IP addresses and apply this to the web servers. Create a second security group for the NFS filestore that allows outbound NFS traffic to the private IP range of the front-end web servers.
  • Restore the instance from the last AMI image. System status checks indicate that the filesystem on the instance is corrupted.
  • Stop and start the instance. This will move the instance to another host.
  • Contact AWS support. Failing a system status check indicates a failure in the underlying hardware and must be addressed by an AWS representative.
  • Reboot the instance. This will stop and start the instance and move it to another host.
  • Windows Server 2016 supports S3 as a target when using storage replicas.
  • Use Storage Gateway.
  • Sync files directly to S3 with the AWS CLI.
  • Use the RDS console to force a reboot of the database instance so that the primary server becomes the master server again.
  • PostgreSQL cannot be replicated across regions. Restore the database backups from an S3 bucket and repoint your database connections to the new instance.
  • Create Read Replicas in other AWS regions. You can designate a new master database from any of the read replicas until the regional failure is resolved.
  • Verify that your instance is configured for multi-AZ support. Database changes will be automatically synced to another region in the event of a failure and RDS will automatically select a new master until the regional failure is resolved.
  • Create Read Replicas in other AWS regions. Ensure read operations against the database occur on an available Read Replica, and send write operations to another region if you need to promote a Read Replica to a standalone database if the master is down.
  • Create a security group rule that allows all traffic from 0.0.0.0/0. This will verify whether or not another rule is denying the traffic.
  • Verify that the assigned security groups allow traffic from your IP address to port 5432. Verify that PostgreSQL is configured to listen to external traffic and is bound to the public interface.
  • Make sure that you are using an Elastic IP and that it is included within the postgresql.conf configuration file.
  • Stop and start the instance. New security group rules will only take effect after a restart.
  • bucketpolicy1 allows any user to perform any action on the objects in the userreports bucket, but limits the objects to read-only permissions for anyone coming from 68.249.108.0 to 68.249.108.255 – except 68.249.108.128.
  • bucketpolicy1 allows any user coming from the IP range of 68.249.108.0 to access objects in the userreports bucket and denies access to 68.249.108.128.
  • bucketpolicy1 allows any user to perform any action on the objects in the userreports bucket – except anyone coming from the IP of 68.249.108.128.
  • bucketpolicy1 allows any user coming from the IP range of 68.249.108.0 to 68.249.108.255 to access objects in the userreports bucket-except anyone coming from the IP of 68.249.108.128.
  • Give the new developer the IAM login that is assigned to the development team. This IAM user should already include all of the policies that a developer would need.
  • Create a IAM user for the new developer. Manually assign policies to the new IAM user account.
  • Do not give the new developer access to the AWS console. Using the IAM user that is assigned to the development group, generate a new set of access keys and label these with the name of the developer.
  • Create a IAM user for the new developer. Assign the new developer a developer group you already created for the other developers.
  • Use the instance storage to serve temporary files that require low I/O latency.
  • Use the instance storage to handle files uploaded by your users. Since it is more secure than an EBS volume, you can isolate any malicious files from infecting your server.
  • Instance storage is faster than EBS volumes, so install the root of the operating system on this volume to speed up server performance.
  • Instance storage is a deprecated option for storage and should not be used.
  • Use Sysprep to shut down the instance during a maintenance window. Create an AMI image and place both servers behind Application Load Balancer with sticky sessions.
  • Launch a new EC2 with the latest version of Windows Server and install the application again. Use Application Load Balancer and sticky sessions to balance between both servers.
  • Create a clone of the server using an AMI image and user Application Load Balancer to balance the traffic between both instances using sticky sessions.
  • Horizontal scaling is not the best practice in this situation. Increase the size of the existing EC2 instance and vertically scale the application.
  • It writes the VPC network flow logs to the CloudWatch FlowLogsGroup log group. You could use this to inspect the network connections of your VPC.
  • It logs all of the network traffic within a VPC except Instance IDs defined by LogVpcID and logs it to the CloudWatch FlowLogsGroup log group.
  • It logs all the network traffic going to and from a single EC2 instance into the CloudWatch FlowLogsGroup log group. You could use this to inspect suspicious network traffic coming into an EC2 instance.
  • It logs all of the DNS requests made by resources within a VPC and logs them to the CloudWatch FlowLogsGroup. Use this to diagnose DNS lookup errors within your environment.
  • The running container count for each service from within CloudWatch.
  • The instance health of each EC2 instance in your cluster from within CloudWatch.
  • Monitor the EC2 service dashboard. Watch for posted outages to the ECS service.

  • All objects within this bucket are assigned public access and could be readable or writable by anyone on the internet. Ensure no sensitive data is being publicly shared within this bucket.
  • All objects within this bucket are writable, which means that the public internet has the ability to upload any file directly to your S3 bucket. Your S3 bucket could be used to serve malware.
  • Some objects within this bucket are assigned public access. Verify that any publicly shared objects within this bucket contain no sensitive data.
  • Objects within this bucket can be made public, if the ACL on that object is set to allow everyone access. Private buckets do not allow you to set public permissions on any object.

  • Configure SES to send the logs of all delivery attempts through Kinesis Firehose. Process each event and look for bounce types and remove these emails from your list.
  • Send all emails through SES with a custom reply-to header. Configure SES to listen for events on this email address and flag any email address that replies to this account as a bounced message and remove it from your email list.
  • Use Web Application Firewall and create a geo match condition to drop all requests from countries that aren’t on you allow list.
  • Use Application Load Balancer to create a new routing rule that looks at source IP address. Add an IP block for the countries that have access.
  • Host the front end of your website in CloudFront and configure a geo restriction on the distribution.
  • Use CloudTrail to monitor the IP addresses of the bad requests. Use Lambda to add these IP addresses to an Application Load Balancer rule that blocks the IPs.

  • RDS will automatically increase the allocated space by 10% and will send the AWS root account an email with resolution steps. Allocate more space to avoid overage charges.
  • The database instance will report a STORAGE_FULL status and become inaccessible if the instance does not have enough remaining storage to operate. Allocate more space to the instance.
  • SQL Server will close all existing connections to the databases and attempt to shrink its log files to reclaim storage space.
  • RDS will automatically increase the allocated space by 5% and will continue to allocate new space up to 50% of the orginal allocated space. When storage space has increase 50%, RDS will automatically stop the instance to preserve data integrity.
  • Use a Network Load Balancer to distribute the traffic across your servers. Use UDP health checks to determine if the server is available to receive traffic.
  • Use Route 53 with HTTP health checks. Create an application on the server to report the readiness status of the vendor-provided server software to Route 53 via HTTP.
  • Use Route 53 with UDP health checks. As you scale up, Route 53 wiwll route the traffic to the new servers if they pass the health checks.
  • Use Application Load Balancer to distribute the traffic across your servers.
  • The outbound rules block UDP port 53, so the server will not be able to resolve any DNS lookups.
  • The outbound rules do not allow for HTTP traffic to leave the instance, so inbound HTTP requests will fail because the clients will never get HTTP responses.
  • The incoming SSH port should not be open to the public. Limit SSH to a single IP address or IP range of controlled addressed, or use a VPN to access the VPC for this server.
  • The all-incoming TCP ports are exposed, which overrides the HTTP and SSH rules and exposes all TCP ports to the public internet.

  • All traffic on all ports is being denied into this instance, which overwrites the HTTP rule and makes it redundant.
  • The instance was launched with the default security group, but there is no way for an administrator to SSH into the instance. Add another rule that allows for SSH access from a secured source, such as a single IP or a range of managed IP addresses.
  • There is nothing wrong with this security group rule. Assuming that sg-269afc5e is applied to other resources that are properly secured, this rule allows all traffic to pass through that is also assigned security group sg-269afc5e.
  • All traffic on all ports are allowed into this instance. This exposes the instance to all public internet traffic and overwrites the incoming HTTP rule.
