NEW QUESTION # 73
A cloud engineer is reviewing the following Dockerfile to deploy a Python web application:
Which of the following changes should the engineer make lo the file to improve container security?
Answer: A
Explanation:
To improve container security, the engineer should add the instruction "USER nonroot" to the Dockerfile. This change ensures that the container does not run as the root user, which reduces the risk of privilege escalation attacks. Running containers as a non-root user is a best practice for enhancing security in containerized environments.References: CompTIA Cloud+ content includes security concerns, measures, and concepts for cloud operations, highlighting container security best practices such as running containers with least privilege to mitigate security risks.
NEW QUESTION # 74
An administrator used a script that worked in the past to create and tag five virtual machines. All of the virtual machines have been created: however, the administrator sees the following results:
{ tags: [ ] }
Which of the following is the most likely reason for this result?
Answer: B
Explanation:
The most likely reason for the script creating virtual machines without tags, despite working in the past, is command deprecation. Cloud service providers update their APIs and CLI commands over time, and a previously used command to tag resources might no longer be valid.
NEW QUESTION # 75
A cloud engineer is designing a cloud-native, three-tier application. The engineer must adhere to the following security best practices:
* Minimal services should run on all layers of the stack.
* The solution should be vendor agnostic.
* Virealization could be used over physical hardware.
Which of the following concepts should the engineer use to design the system to best meet these requirements?
Answer: A
Explanation:
Microservices architecture is the most suitable design principle that aligns with the security best practices mentioned. It involves developing a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. This architecture minimizes the services running on each layer, allows for vendor-agnostic solutions, and is well-suited for virtualization over physical hardware.
Microservices as an architectural approach is discussed in the context of cloud-native applications within the CompTIA Cloud+ material.
NEW QUESTION # 76
Which of the following container commands implements network port mapping?
Answer: A
Explanation:
The -p option in docker run maps a host port to a container port, as shown in -p 80:8080, enabling network port mapping.
NEW QUESTION # 77
A cloud administrator needs to distribute workloads across remote data centers for redundancy reasons. Which of the following deployment strategies would eliminate downtime, accelerate deployment, and remain cost efficient?
Answer: A
Explanation:
Blue-green deployment is the strategy that can eliminate downtime, accelerate deployment, and remain cost-efficient. It involves running two identical production environments, only one of which is live at any given time (blue or green). When it's time to deploy, the new version is released to the inactive environment (green), which is then thoroughly tested. Once ready, the traffic is switched over, making the green environment live.
