A company developed an online trading platform. The engineering team selected event-based scaling for the platform’s underlying resources. The platform resources scale up with every 2,000 subscribed users. The engineering team finds out that although compute utilization is low scaling is still occurring. Which of the following statements best explains why this is the case?
Answer(s): D
Event-based scaling triggers resource adjustments based on predefined events rather than actual compute utilization or system load. In this case, the system is scaling up every time 2,000 new users subscribe, regardless of whether the underlying compute resources are actually under stress. This can lead to unnecessary scaling, increasing costs without improving performance.To optimize scaling, the engineering team should consider a hybrid approach that combines event-based triggers with resource utilization metrics (e.g., CPU, memory, or network load) to prevent over-provisioning.
A bank informs an administrator that changes must be made to backups for long-term reporting purposes. Which of the following is the most important change the administrator should make to satisfy these requirements?
Answer(s): C
For long-term reporting purposes, the retention policy of backups is the most important aspect to modify. Banks and financial institutions are often required to store data for extended periods to meet compliance and regulatory requirements. Adjusting the retention policy ensures that backups are kept for the necessary duration while aligning with industry standards and legal mandates.
A security analyst confirms a zero-day vulnerability was exploited by hackers who gained access to confidential customer data and installed ransomware on the server. Which of the following steps should the security analyst take? (Choose two.)
Answer(s): D,F
A software engineer is integrating an application to the cloud that is web socket based. Which of the following applications is the engineer most likely deploying?
WebSockets enable real-time, bidirectional communication between a client and a server, making them ideal for applications that require low-latency, continuous data exchange. Chat applications rely on WebSockets to ensure instant message delivery, presence updates, and live interactions without the overhead of repeatedly polling the server.
Which of the following is the best type of database for storing different types of unstructured data that may change frequently?
A non-relational (NoSQL) database is the best choice for storing unstructured and frequently changing data. Unlike relational databases, which require fixed schemas and structured data, NoSQL databases offer flexibility and scalability, making them ideal for handling varied data formats such as JSON, XML, videos, and logs.
