A software engineer needs to transfer data over the internet using programmatic access while also being able to query the data. Which of the following will best help the engineer to complete this task?
Answer(s): D
GraphQL is a query language for APIs that allows clients to request specific data from a server and enables efficient data transfer over the internet. It’s designed for programmatic access to data and allows clients to define the structure of the response they need, which is ideal for querying data as mentioned in the question.
Which of the following is a field of computer science that enables computers to identify and understand objects and people in images and videos?
Computer vision is the field of computer science focused on enabling computers to interpret and make sense of visual information, such as identifying and understanding objects and people in images and videos.
A company needs to deploy its own code directly in the cloud without provisioning additional infrastructure. Which of the following is the best cloud service model for the company to use?
Answer(s): A
PaaS (Platform as a Service) provides a platform that allows companies to deploy their own code directly without managing the underlying infrastructure. It offers the runtime environment and tools needed to develop, test, and deploy applications, so developers can focus on coding rather than managing servers or networking.
A company just learned that the data in its object storage was accessed by an unauthorized party. Which of the following should the company have done to make the data unusable?
Encrypting data at rest ensures that, even if an unauthorized party gains access to the storage location, the data remains unreadable and unusable without the appropriate decryption keys.
A customer relationship management application, which is hosted in a public cloud IaaS network, is vulnerable to a remote command execution vulnerability. Which of the following is the best solution for the security engineer to implement to prevent the application from being exploited by basic attacks?
WAF (Web Application Firewall) is specifically designed to protect web applications by filtering and monitoring HTTP traffic. It can prevent common web-based attacks, including remote command execution (RCE) attacks, by inspecting incoming requests and blocking malicious payloads.
Which of the following is a difference between a SAN and a NAS?
SAN (Storage Area Network) typically uses high-speed protocols such as Fibre Channel (FC) or iSCSI, which are designed for fast data access and are generally faster than the network protocols used by NAS. SANs are often used in environments where high-performance storage access is required.NAS (Network Attached Storage) uses standard network protocols, like NFS (Network File System) or SMB (Server Message Block), over TCP/IP, which are generally slower than the specialized storage protocols used by SAN.
A cloud engineer is troubleshooting an application that consumes multiple third-party REST APIs. The application is randomly experiencing high latency. Which of the following would best help determine the source of the latency?
Enabling tracing provides detailed insights into the timing of each step in an application’s process, allowing the engineer to see the exact response times and any patterns in latency for each third-party API request. This can pinpoint whether latency issues stem from a particular API, network delays, or other issues in the request/ response cycle.
A cloud engineer is reviewing the following Dockerfile to deploy a Python web application:Which of the following changes should the engineer make to the file to improve container security?
Adding USER nonroot ensures that the application runs as a non-root user within the container, reducing the risk of privilege escalation and limiting the damage that could be done if the container is compromised. Running containers as root is generally discouraged for security reasons.
