A company is using a hybrid cloud environment. The private cloud is hosting the business applications, and the cloud services are being used to replicate for availability purposes.
The cloud services are also being used to accommodate the additional resource requirements to provide continued services. Which of the following scalability models is the company utilizing?
Correct Answer:
C
Cloud bursting is a scalability model that allows a company to use a hybrid cloud environment to handle peak or unpredictable workloads. Cloud bursting involves using the private cloud to host the core or critical applications, and using the public cloud to provide additional or temporary resources when the demand exceeds the capacity of the private cloud .
Cloud bursting can help a company to:
Improve the availability and reliability of the applications by replicating them across multiple cloud platforms and locations .
Optimize the performance and efficiency of the applications by dynamically allocating and releasing resources based on the workload and traffic .
Reduce the cost and complexity of the IT infrastructure by leveraging the pay-as-you-go and on-demand models of the public cloud .

A systems administrator in a large enterprise needs to alter the configuration of one of the finance department’s database servers.
Which of the following should the administrator perform FIRST?
Correct Answer:
B
The SA would do the other three regardless of the need to alter configurations. In this situation, the SA would have to present the change to the CCB in order to do the alteration.
There is no clarification on whether the change management process has been gone
through. Any changes, regardless of how small or big, must go through the change management process. This allows proposals to be heard by end-users, management, and possibly stockholders. From there, it will be reviewed and either approved or denied, with reasons specified. From there, the administrator(s) can do whatever processes are necessary.
Change management is a process or procedure that defines the steps, roles, and responsibilities for implementing, documenting, and communicating any changes or updates to a system or service. Change management can help ensure that any changes or updates are done in a controlled and consistent manner, minimizing any risks or impacts to the system or service. Performing change management is the first thing that a systems administrator should do before altering the configuration of one of the finance department’s database servers, as it can ensure that the change request is approved, authorized, tested, and verified before applying it to the database server.

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?
Correct 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.

A company is concerned it will run out of VLANs on its private cloud platform in the next couple months, and the product currently offered to customers requires the company to allocate three dedicated, segmented tiers. Which of the following can the company implement to continue adding new customers and to maintain the required level of isolation from other tenants?
Correct Answer:
C
One possible solution for the company to continue adding new customers and to maintain the required level of isolation from other tenants is to implement VXLAN. VXLAN is a network virtualization technology that can extend VLAN by adding a 24-bit segment ID, which allows up to 16 million unique virtual segments. VXLAN can encapsulate layer 2 Ethernet frames within layer 3 IP packets, and tunnel them across the underlying network. VXLAN can provide logical isolation and security for different tenants, as well as scalability and flexibility for large cloud computing environments1.

A company needs a solution to find content in images. Which of the following technologies, when used in conjunction with cloud services, would facilitate the BEST solution?
Correct Answer:
C
Artificial intelligence (AI) is the technology that, when used in conjunction with cloud services, would facilitate the best solution for finding content in images. AI is a branch of computer science that aims to create machines or systems that can perform tasks that normally require human intelligence, such as reasoning, learning, decision making, etc. AI can be used to analyze images and extract information such as objects, faces, text, emotions, etc., using techniques such as computer vision, machine learning, natural language processing, etc. AI can help to find content in images faster, more accurately, and more efficiently than manual methods.
