Question 1

A cloud solutions architect has an environment that must only be accessed during work hours. Which of the following processes should be automated to BEST reduce cost?

AScaling of the environment after work hours

BImplementing access control after work hours

CShutting down the environment after work hours

DBlocking external access to the environment after work hours

Answer : C

One of the main benefits of cloud computing is that you only pay for the resources that you use.However, this also means that you need to manage your cloud resources efficiently and avoid paying for idle or unused resources1.

Shutting down the environment after work hours is a process that can be automated to best reduce cost in a cloud environment that must only be accessed during work hours. This process involves stopping or terminating the cloud resources, such as virtual machines, databases, load balancers, etc., that are not needed outside of the work hours.This can significantly reduce the cloud bill by avoiding charges for compute, storage, network, and other services that are not in use2.

The other options are not the best processes to automate to reduce cost in this scenario:

Option A: Scaling of the environment after work hours. Scaling is a process that involves adjusting the number or size of cloud resources to match the demand or workload. Scaling can be done manually or automatically using triggers or policies. Scaling can help optimize the performance and availability of a cloud environment, but it does not necessarily reduce the cost. Scaling down the environment after work hours may reduce some costs, but it may still incur charges for the remaining resources.Scaling up the environment before work hours may increase the cost and also introduce delays or errors in provisioning new resources3.

Option B: Implementing access control after work hours. Access control is a process that involves defining and enforcing rules and policies for who can access what resources in a cloud environment. Access control can help improve the security and compliance of a cloud environment, but it does not directly affect the cost.Implementing access control after work hours may prevent unauthorized access to the environment, but it does not stop or terminate the resources that are still running and consuming cloud services4.

Option D: Blocking external access to the environment after work hours. Blocking external access is a process that involves restricting or denying network traffic from outside sources to a cloud environment. Blocking external access can help protect the environment from potential attacks or breaches, but it does not impact the cost. Blocking external access after work hours may prevent unwanted requests or connections to the environment, but it does not shut down or release the resources that are still active and generating cloud charges.

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 administrator needs to implement a mechanism to monitor the expense of the company's cloud resources.

Which of the following is the BEST option to execute this task with minimal effort?

AAsk the cloud provider to send a daily expense report

BSet custom notifications for exceeding budget thresholds

CUse the API to collect expense information from cloud resources

DImplement a financial tool to monitor cloud resource expenses

Answer : B

Setting custom notifications for exceeding budget thresholds is the best option to execute the task of monitoring the expense of the company's cloud resources with minimal effort, as it can automate and simplify the process of tracking and alerting the cloud administrator about any overspending or wastage of cloud resources. Setting custom notifications can also help optimize the cost and performance of cloud resources, as it can enable timely and proactive actions to adjust or optimize the resource allocation or consumption based on the budget limits.

Question 4

A cloud engineer is responsible for managing two cloud environments from different MSPs. The security department would like to inspect all traffic from the two cloud environments.

Which of the following network topology solutions should the cloud engineer implement to reduce long-term maintenance?

AChain

BStar

CMesh

DHub and spoke

Answer : D

Hub and spoke is a type of network topology that consists of a central node or device (hub) that connects to multiple peripheral nodes or devices (spokes). Hub and spoke can help reduce long-term maintenance for managing two cloud environments from different MSPs, as it can simplify and centralize the network configuration and management by using the hub as a single point of contact and control for the spokes. Hub and spoke can also improve network performance and security, as it can reduce latency, bandwidth consumption, and network congestion by routing traffic through the hub.

Question 5

A systems administrator wants to repurpose and implement a legacy tool that has been used in the past as a multicloud monitoring system. Which of the following will be the most probable challenges in the future caused by this implementation? (Select two).

AConnectivity issues.

BLimited staff skill sets.

CLicensing issues.

DMessaging errors.

ELatency issues.

FLack of support.

Answer : A, F

Detailed

A . Connectivity issues: Legacy tools might not fully support multicloud environments, leading to potential integration challenges.

F . Lack of support: Legacy systems are often outdated and no longer maintained, which can result in a lack of vendor or community support for troubleshooting.

Question 6

During a security incident, an laaS compute instance is detected to send traffic to a host related to cryptocurrency mining. The security analyst handling the incident determines the scope of the incident is limited to that particular instance. Which of the following should the security analyst do NEXT?

AIsolate the instance from the network into quarantine.

BPerform a memory acquisition in the affected instance.

CCreate a snapshot of the volumes attached to the instance.

DReplace the instance with another from the baseline.

Answer : A

The first step in incident response is to contain the incident activities and attackers, which means preventing them from spreading to other systems or causing more damage. In this case, the security analyst should isolate the instance from the network into quarantine, which means cutting off its communication with other hosts and services. This will stop the cryptocurrency mining activity and prevent the attacker from accessing the instance remotely. Isolating the instance also preserves the evidence for further analysis and investigation.

Question 7

A web consultancy group currently works in an isolated development environment. The group uses this environment for the creation of the final solution, but also for showcasing it to customers, before commissioning the sites in production. Recently, customers of newly commissioned sites have reported they are not receiving the final product shown by the group, and

the website is performing in unexpected ways. Which of the following additional environments should the group adopt and include in its process?

AProvide each web consultant a local environment on their device.

BRequire each customer to have a blue-green environment.

CLeverage a staging environment that is tightly controlled for showcasing.

DInitiate a disaster recovery environment to fail to in the event of reported issues.

Answer : C

A staging environment is a type of development environment that is used to test and demonstrate the final product before deploying it to the production environment. A staging environment can help the web consultancy group avoid the issues of delivering a different or faulty product to the customers, as it can ensure that the product is fully functional, compatible, and secure. A staging environment can also help the group showcase the product to the customers in a realistic and controlled way, as it can mimic the production environment and avoid any interference from other development activities.A staging environment can be leveraged by using cloud services that allow for easy provisioning, scaling, and deployment of web applications
