A cloud administrator notices that a virtual machine running a critical application is using 95% CPU consistently. The application is single-threaded and performance is degraded. Which action should the administrator take to resolve the issue?
The application is single-threaded, meaning it can only utilize one CPU core at a time. Increasing the CPU clock speed directly improves the processing speed of that single thread, which resolves the performance degradation. Option C is correct because migrating to a host with a …Read full explanation
A cloud engineer needs to ensure that a web application can scale out automatically during traffic spikes. Which design best practice should be implemented?
Option D is correct because an auto scaling group combined with a load balancer automatically adds or removes VM instances based on predefined metrics (e.g., CPU utilization, request count), ensuring the web application scales out horizontally during traffic spikes without manual…Read full explanation
A company uses a hybrid cloud model with an on-premises data center and a public cloud. The network team reports that traffic between the cloud and on-premises is experiencing high latency and packet loss. The cloud administrator verifies that the VPN connection is up. What is the most likely cause?
When a VPN tunnel is up but traffic experiences high latency and packet loss, a mismatched Maximum Transmission Unit (MTU) size is a common cause. This occurs because packets larger than the tunnel's MTU must be fragmented, and if fragmentation is not properly handled (e.g., due …Read full explanation
