Question 1

A cloud administrator is assessing the scaling of an infrastructure stack. When viewing the configuration, the cloud administrator notices that the servers have a maximum limit of three. Which of the following is a way to increase throughput for the three servers without adjusting the maximum scaling limits?

ASelecting a machine with more resources.

BReducing the size of the image being deployed.

CUsing faster block storage on the machines.

DIncreasing the scaling minimum to three.

Answer : A

Detailed

A . Selecting a machine with more resources: Upgrading to servers with higher compute, memory, or network capacity allows the infrastructure to handle greater throughput without increasing the server count.

Question 2

A cloud administrator receives a billing report and notices the IT department billing has been the same for the last few months, despite the deployment of ten new instances for the SIEM solution. Which of the following is the most likely cause of the issue?

AInconsistent hostnames.

BMisconfigured VM names.

CIncomplete provisioning tasks.

DIncorrect tagging.

Answer : D

Detailed

D . Incorrect tagging: Many cloud providers use tags for billing and tracking resource usage. Incorrect or missing tags can prevent the new instances from being associated with the correct billing group, leading to inaccurate billing.

Question 3

A cloud engineer gathered the following requirements for a factory automation system:

Assembly line systems are latency-sensitive.

Internet connectivity issues are common and can be prolonged.

Services must support a 99.999% system uptime.

Which of the following components would be useful in implementing a hybrid model? (Select two).

ACloud-based orchestration.

BCloud edge devices.

CLocal services.

DCloud-managed services.

ECentralized logging and alerting.

FCDN provider.

Answer : B, C

Detailed

B . Cloud edge devices: Edge devices process data closer to the factory, reducing latency and improving performance for sensitive applications.

C . Local services: Local services ensure continued operation during internet outages, maintaining high availability for critical systems.

Question 4

A systems administrator is planning the storage requirements for a two-disk mirror of a server OS disk partition. Which of the following is the amount of disk space available in the mirrored volume?

A30%

B50%

C75%

D100%

Answer : B

Detailed

B . 50%: In a two-disk mirror (RAID 1), one disk is used for redundancy. Therefore, only 50% of the total disk capacity is available for storage.

Question 5

A systems administrator receives an alert that VDI performance on the cluster is poor. Opening any application takes one to two minutes. The administrator investigates and finds the following conditions:

Cluster memory utilization: 65%

Cluster SSD utilization: 70%

Average VM CPU wait time: 14%

Cluster CPU utilization: 75%

Which of the following actions should the administrator take to improve VDI performance?

AAdd CPU resources to the cluster.

BIncrease the number of vCPUs per VM.

CAdd memory to the nodes in the cluster.

DIncrease the amount of SSD storage in the cluster.

Answer : A

Detailed

A . Add CPU resources to the cluster: High CPU wait time indicates insufficient CPU resources for handling workload demands. Adding CPUs to the cluster will reduce latency and improve application performance.

Question 6

A cloud engineer is troubleshooting poor performance on a corporate website configured behind a cloud application load balancer. The following output was collected on the cloud console:

CDN status: Configured and content replicated to edge locations.

WAF status: 10 rules applied; 8,787,638 hits / 37,634 blocks.

Listening on ports: 80/443.

Forwarding traffic to instances: 5 (2 healthy).

Autoscaling events: 25.

Which of the following is the most likely cause of the issue?

AThe web servers are not responding properly.

BThe web firewall is blocking legitimate traffic.

CThe CDN should not be used during high loads.

DAutoscaling events are too high.

Answer : A

Detailed

A . The web servers are not responding properly: Only two of five servers are healthy, indicating a bottleneck. Load balancers cannot efficiently distribute traffic when server health is low.

Question 7

A cloud architect is receiving complaints from VDI users overseas about slowness, even though the remote office has Gigabit internet. Which of the following will most likely solve the issue?

AIncreasing bandwidth.

BEnabling compression.

CLowering latency.

DAdding redundancy.

Answer : C

Detailed

C . Lowering latency: Latency affects response times more than bandwidth in high-speed networks. Techniques like optimizing routing and using edge computing can reduce latency.
