A company operates a website that allows customers to upload, share, and retain full ownership of their photographs. Which of the following could affect image ownership as the website usage expands globally?
Answer(s): A
Data sovereignty refers to the concept that data is subject to the laws and regulations of the country where it is physically located. As the website usage expands globally, different countries may have different regulations concerning data ownership, privacy, and intellectual property. This could affect image ownership as data is stored or processed in multiple jurisdictions, each with potentially different rules regarding ownership and rights.
A systems administrator is provisioning VMs according to the following requirements:-A VM instance needs to be present in at least two data centers.-During replication, the application hosted on the VM tolerates a maximum latency of one second.-When a VM is unavailable, failover must be immediate.Which of the following replication methods will best meet these requirements?
Answer(s): C
Live replication (or live migration) involves continuously replicating changes from one virtual machine to another in real time or near real time, ensuring that the VM instance is available in at least two data centers with minimal latency. This approach supports immediate failover since the replicated VM can take over seamlessly if the primary VM fails.
A DevOps engineer is performing maintenance on the mail servers for a company’s web application. Part of this maintenance includes checking core operating system updates. The servers are currently running version 3.2 of the operating system. The engineer has two update options—one to version 4.1 and the other to version 3.7. Both versions are fully supported by the operating system manufacturer. Which of the following best describes the action the engineer should take?
Before performing an update, it is essential for the DevOps engineer to understand the impact of the update. Reading the release notes of version 4.1 will provide critical information on new features, bug fixes, potential compatibility issues, and changes that could affect the web application's functionality. This will help the engineer make an informed decision about which version to upgrade to and ensure that the update process proceeds smoothly without unintended consequences.
Which of the following is the most cost-effective and efficient strategy when migrating containers to the cloud?
Answer(s): B
Replatforming is the process of making slight modifications to the existing container setup to take advantage of cloud-native services without completely rewriting the application. This strategy is cost-effective and efficient because it involves minimal changes while still allowing the application to benefit from the cloud's scalability, flexibility, and managed services. For containerized workloads, replatforming often involves adapting the deployment to run on managed container services provided by the cloud provider.
An organization’s web application experiences periodic bursts of traffic when a new video is launched. Users are reporting poor performance in the middle of the month. Which of the following scaling approaches should the organization use to scale based on forecasted traffic?
Scheduled scaling is the best approach for handling forecasted traffic. If the organization knows that the web application experiences periodic bursts of traffic, such as when a new video is launched in the middle of the month, scaling can be scheduled in advance to accommodate the anticipated increase in demand. This approach helps ensure adequate resources are available to handle the expected load, improving performance during peak times.
