A cloud infrastructure administrator updated the IP tables to block incoming connections and outgoing responses to 104.225.110.203. Which of the following vulnerability management steps is this an example of?
Answer(s): B
Remediation refers to the actions taken to fix or mitigate a vulnerability after it has been identified. In this case, the cloud infrastructure administrator updated the IP tables to block incoming connections and outgoing responses to a specific IP address, which is an action taken to mitigate a potential threat or vulnerability. This is a clear example of remediation.
An administrator needs to adhere to the following requirements when moving a customer’s data to the cloud:-The new service must be geographically dispersed.-The customer should have local access to data.-Legacy applications should be accessible.Which of the following cloud deployment models is most suitable?
Answer(s): C
A hybrid cloud deployment model combines on-premises infrastructure (or a private cloud) with public cloud services. It is the most suitable option when: Geographically dispersed data storage is needed, as a hybrid model can leverage both local infrastructure and globally dispersed cloud resources. The customer requires local access to data, which can be provided via on-premises infrastructure. Legacy applications need to be accessible, which can be maintained in an on-premises or private environment while taking advantage of the scalability of the public cloud for other workloads.
A company’s VMs that are created using the noncritical application tag are automatically shut down at 5:00 p.m. using a cronjob. Which of the following actions would allow a cloud engineer to stop all unresponsive instances with the least effort in case the automation fails?
Using the cloud provider command line to stop instances based on their tags allows the cloud engineer to target only the instances tagged as "noncritical application" and shut them down efficiently with minimal effort. This approach is both quick and precise, as it only affects the relevant instances, rather than manually filtering through all instances or relying on other more time-consuming methods.
A company uses containers stored in Docker Hub to deploy workloads for its IaaS infrastructure. The development team releases changes to the containers several times per hour.Which of the following should a cloud engineer do to prevent the proprietary code from being exposed to third parties?
Answer(s): D
Using private repositories for storing Docker containers ensures that proprietary code is not publicly accessible on Docker Hub or any other public container registry. This approach limits access to only authorized users, protecting the proprietary code from being exposed to third parties.
A social networking company operates globally. Some users from Brazil and Argentina are reporting the following error: website address was not found. Which of the following is the most likely cause of this issue?
Since users from Brazil and Argentina are reporting that the website address was not found, it suggests a regional issue affecting users in a specific geographic area. This is most likely due to a regional DNS provider outage, which prevents DNS resolution for users in that region.
