A company wants to optimize cloud resources and lower the overhead caused by managing multiple operating systems. Which of the following compute resources would be best to help to achieve this goal?
Answer(s): B
Containers allow multiple applications to run in isolated environments while sharing the same operating system kernel, which significantly reduces the overhead of managing multiple OS instances. Containers are lightweight, efficient, and ideal for optimizing resource utilization in cloud environments.
A company runs a discussion forum that caters to global users. The company’s monitoring system reports that the home page suddenly is seeing elevated response times, even though internal monitoring has reported no issues or changes. Which of the following is the most likely cause of this issue?
Answer(s): C
DDoS (Distributed Denial of Service) attacks can lead to elevated response times by overwhelming the application with a large volume of requests, which can slow down response times for legitimate users. Since there were no internal changes and the issue seems to be sudden, a DDoS attack is a plausible explanation.
Which of the following migration types is best to use when migrating a highly available application, which is normally hosted on a local VM cluster, for usage with an external user population?
On-premises to cloud migration is ideal for moving a highly available application from a local VM cluster to a cloud environment, especially when the application will be accessed by an external user population. This approach leverages the scalability, availability, and accessibility of cloud resources, which are well-suited for handling external traffic and providing high availability.
A cloud architect attempts to modify a protected branch but is unable to do so. The architect receives an error indicating the action cannot be completed. Which of the following should the architect try instead?
Creating a pull request is the typical workflow for modifying a protected branch in many version control systems, especially in collaborative projects. Protected branches are often restricted to prevent direct modifications, so changes must go through a pull request, allowing for review and approval before they are merged.
Which of the following container storage types loses data after a restart?
Ephemeral storage is temporary storage that is created and removed with the container. Data stored in ephemeral storage is lost when the container restarts or shuts down.
