A newly configured VM fails to run application updates despite having internet access. The updates download automatically from a third-party network. Given the following output:Which of the following troubleshooting steps would be best to take?
Answer(s): A
The dig command output shows a successful response for apac.updateserver.net with an IP address (38.102.218.7), but a timeout for na.updateserver.net. This suggests that the DNS server is able to resolve some domain names but is failing to resolve others. This likely points to a DNS configuration issue, such as missing or misconfigured DNS records, issues with the DNS resolver, or network restrictions affecting certain domains.To troubleshoot, the cloud engineer should:-Check DNS configurations on the VM, including the DNS server settings.-Ensure the VM can resolve all necessary domains for the application update process.
Which of the following communication methods between on-premises and cloud environments would ensure minimal-to-low latency and overhead?
Answer(s): C
Direct connection (often referred to as dedicated or private connection) provides a direct, private link between on-premises infrastructure and the cloud environment, bypassing the public internet. This method results in minimal latency, low overhead, and consistent bandwidth, making it the best choice for applications requiring high performance and low latency.
A cloud engineer is collecting web server application logs to troubleshoot intermittent issues. However, the logs are piling up and causing storage issues. Which of the following log mechanisms should the cloud engineer implement to address this issue?
Answer(s): B
Log rotation is a mechanism used to manage the size of log files by periodically archiving or deleting older log entries to prevent them from taking up excessive disk space. By implementing log rotation, the cloud engineer can ensure that log files are regularly compressed or removed, reducing storage issues while still retaining important log information for troubleshooting.
Which of the following cloud native architecture designs is the most easily maintained, decentralized, and decoupled?
Answer(s): D
Microservices architecture is designed to be highly maintainable, decentralized, and decoupled. In this approach, an application is broken down into smaller, independent services, each responsible for a specific function or business capability. These services communicate with each other via APIs, allowing for greater flexibility, scalability, and ease of maintenance. The decoupled nature of microservices enables teams to work on different services without affecting others, making it ideal for cloud-native environments.
A cloud security analyst is looking for existing security vulnerabilities on software applications. Which of the following describes this vulnerability management phase?
The Identification phase in vulnerability management involves discovering and identifying existing security vulnerabilities in software applications, systems, and networks. In this phase, the security analyst uses tools, scans, and audits to detect potential vulnerabilities before moving on to the next phases, which include analyzing, reporting, and remediation.
