A cloud engineer notices on a dashboard that the host is close to reaching maximum capacity for the CPU and memory in the cloud environment, which could cause performance issues. The cloud environment has 100 servers, with 25% of the servers consuming their compute only during peak business hours, 25% consuming half of the allocated resources, and the remaining 50% using the compute during off hours. Which of the following should the engineer perform to optimize the efficiency of the compute usage in the cloud?

A. Add additional CPUs and RAM to the host that is serving the cloud.

B. Adjust the cloud workload by migrating resource-intensive applications to different hosts.

C. Add additional hosts to the environment using the cloud management tool.

D. Enable automatic scaling in the cloud management tool.

A cloud administrator is securing access to a VM using an IaaS cloud platform. The administrator must perform this task using an automated method, allow administrators to perform any method and expose any property of the VM, deny access for everyone else, and allow only read-only access to everyone else. Given this scenario, which of the following should the administrator use to BEST meet these requirements?

A. jQuery

B. JavaScript

C. Java

D. JSON

An administrator is no longer receiving alerting messages from the web server platform that recently failed over to a new secondary datacenter due to a power failure. Which of the following is the cause of the problem?

A. Port 21 in only allowed inbound at the primary datacenter

B. Port 22 to the log server is blocked outbound

C. Port 162 in DMZ is blocked inbound

D. Port 162 in DMZ is blocked outbound

Asynchronous data replication for a SaaS application occurs between Regions A and B. Users in Region A are reporting that the most current data for an insurance claims application is not available to them until after 11:30 a.m. The cloud administrator for this SaaS provider checks the network utilization and finds that only about 10% of the network bandwidth is being used.

Which of the following describes how the cloud administrator could BEST resolve this issue?

A. Check the storage utilization logs in both regions.

B. Check the RAM utilization logs in both regions.

C. Check the CPU utilization logs in both regions.

D. Check the storage commit logs in both regions.

A cloud technology vendor has released an update to its product. A company providing cloud services need to quickly adopt the update to provide support to its customers. Which of the following is the MOST efficient action to complete this task?

A. Use a virtualization tool to apply patches to cloud resources.

B. Use an automatic system restart to update the cloud resources.

C. Use an orchestration tool to automate updates across cloud resources.

D. Use custom scripts to distribute the release to the cloud resources.

A company is migrating its application to a cloud provider. Six months before going live, a representative from each stakeholder group validated the functionality and performance in the QA environment and did not identify any issues. After going live, the system response time is slower that the testing environment. Which of the following is the MOST likely gap in the testing plan?

A. The test scenario audiences are different between QA and production.

B. The application version deployed in production is different than the one deployed in QA.

C. System configuration testing in QA and production is different.

D. The test plan in QA is different than the production environment.

A law firm wants to limit log retention to the minimum required by law and regulation. Which of the following is the engineer most likely to do FIRST?

A. Create a 2GB external hard drive to log all activities.

B. Configure all systems in scope to log activities in support of company policies.

C. Configure a daily rotation on all workstations to limit the logs' discovery scope.

D. Deduplicate, compress, and encrypt all logs before archiving them.

A cloud engineer is upgrading a high-performance computing cluster for the private cloud. The existing cluster is being replaced with GPU servers. A single GPU server is capable of the same teraflops output as 10 CPU servers. The current cluster configuration is as follows:

1.

100 quad-core CPU servers capable of producing 100 teraflops.

2.

The baseline and current usage is 100%.

The new cluster was set up and benchmarked in four different configurations. Which of the following configurations will meet the baseline teraflops performance of the cluster while maintaining the current usage?

A. 1 GPU server, 80 CPU servers

B. 2 GPU servers, 50 CPU servers

C. 5 GPU servers, 40 CPU servers

D. 9 GPU servers, 10 CPU servers
