Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 277 discussion

Exam question from Amazon's AWS Certified DevOps Engineer - Professional DOP-C02
Question #: 277
Topic #: 1
[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company runs applications on Windows and Linux Amazon EC2 instances. The instances run across multiple Availability Zones in an AWS Region. The company uses Auto Scaling groups for each application.

The company needs a durable storage solution for the instances. The solution must use SMB for Windows and must use NFS for Linux. The solution must also have sub-millisecond latencies. All instances will read and write the data.

Which combination of steps will meet these requirements? (Choose three.)

  • A. Create an Amazon Elastic File System (Amazon EFS) file system that has targets in multiple Availability Zones.
  • B. Create an Amazon FSx for NetApp ONTAP Multi-AZ file system.
  • C. Create a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume to use for shared storage.
  • D. Update the user data for each application’s launch template to mount the file system.
  • E. Perform an instance refresh on each Auto Scaling group.
  • F. Update the EC2 instances for each application to mount the file system when new instances are launched.

To meet the requirements of the scenario, the company should take the following steps: Create an Amazon FSx for NetApp ONTAP Multi-AZ file system (Option B): Amazon FSx for NetApp ONTAP supports both SMB (for Windows) and NFS (for Linux), and it provides sub-millisecond latencies. It also supports Multi-AZ configurations for high availability and durability. Update the user data for each application’s launch template to mount the file system (Option D): This ensures that every new instance launched by the Auto Scaling group will have the file system mounted. Perform an instance refresh on each Auto Scaling group (Option E): This will update the existing instances with the new launch template configuration, ensuring that they have the file system mounted.

Option B: Create an Amazon FSx for NetApp ONTAP Multi-AZ file system. This provides high-performance storage with support for both SMB and NFS protocols. Option D: Update the user data for each application’s launch template to mount the file system. This ensures that the file system is automatically mounted when new instances are launched. Option F: Update the EC2 instances for each application to mount the file system when new instances are launched. This ensures that all instances can read and write data to the file system

after review and check, BDE will be better Option E focuses on updating existing instances with the new configurations by replacing them with new instances based on the updated launch template. This is particularly useful when you want all instances, including those currently running, to immediately adhere to new configurations. B. Amazon FSx for NetApp ONTAP Multi-AZ file system. - SMB and NFS Support - Sub-Millisecond Latency - Multi-AZ Availability: ensures HA and fault tolerance, as the data is replicated across multiple Availability Zones, which aligns with the requirement for a durable storage solution. D. Update the user data for each application’s launch template to mount the file system. - Automated Mounting the FSx file system at startup - Protocol-Specific Commands: For Windows instances, mount the SMB share, while for Linux instances, mount the NFS share

Not A. Amazon EFS as supports only NFS, not SMB support for Windows. Not C. Amazon EBS volume not natively support SMB or NFS, and EBS is block storage devices that attach to individual EC2 instances and do not support being shared directly across multiple instances.

Not Option F "Update the EC2 instances for each application to mount the file system when new instances are launched." - because this is more about ensuring that future instances have the correct configuration, without immediately affecting running instances. It sets the stage for consistency moving forward but does not address existing instances. - and future instances also take care by Option D

Update the EC2 instances for each application to mount the file system when new instances are launched. - Configuration Consistency: ensures that every new instance launched as part of the Auto Scaling group auto mounts the FSx file system. - Ease of Management: By automating the mounting process, you reduce the administrative overhead and potential for errors, ensuring a consistent and reliable setup.

Amazon EBS volume not natively support SMB or NFS, and EBS is block storage devices that attach to individual EC2 instances and do not support being shared directly across multiple instances. Not E, Perform an instance refresh on each Auto Scaling group. - Not Necessary for Mounting: An instance refresh primarily updates instances in the Auto Scaling group to use new configurations or launch templates. While useful in other scenarios, it doesn't directly relate to mounting the file system or affect the requirement for shared storage. - Redundant with Updated Launch Templates: If launch templates and user data scripts are updated correctly, new instances will automatically mount the file system, making a manual refresh unnecessary unless other updates are needed.
