Which of the following cloud deployment models offers the best scalability and cost effectiveness? A. Public B. Private C. Community D. Hybrid

A. Public clouds, such as Microsoft Azure and Amazon Web Service (AWS), offer the best in scalability, reliability, and cost effectiveness. Private clouds do not offer as much cost effectiveness. Community clouds and hybrid clouds are between public and private in terms of scalability and cost effectiveness.

The development team has added a new search feature that has never been tested before. Which testing process is more important than the others? A. Load testing B. Regression testing C. Sandbox testing D. Penetration testing

A. The new feature is a search function. Searches require increased CPU and memory usage. Load testing will be needed to determine which resources will need to be increased. Regression testing should be done, but since this is a new feature, there are no previous bugs concerning searches that can be performed. Sandbox testing should have already been performed. Penetration testing is important from a security perspective but does not address the requirements in the question.

Your company uses a financial transactions database that updates frequently. If a natural disaster occurred, any data backup older than one hour would not be useful to the company. To ensure that backups are always more current, what needs to be specified in the disaster recovery plan? A. RPO B. RTO C. TSO D. SLA

A. The recovery point objective (RPO) defines the maximum age of files that must be recovered from backups in order to restore normal operations. In this case, the RPO needs to be less than an hour. The recovery time objective (RTO) specifies how long services can be down in the event of a disaster. There is no TSO in disaster recovery plans. The service level agreement (SLA) usually contains a section for the disaster recovery plan.

The CFO wants to be notified whenever the monthly estimated costs reach $2,000. You will set up to notify once the threshold is met. A. Logging B. Alerts C. API D. Autoscaling

B. Alerts can perform actions when events occur or when thresholds are met. Logging does not perform notifications but can be used to trigger an alert. API can be used to set up alerts. Autoscaling is used for increasing or decreasing resources.

A blue/green deployment is a deployment used primarily when doing____ on production infrastructure. A. Regression testing B. Upgrades and patching C. Sandbox testing D. Development

B. Blue/green deployment is used for upgrades and patching. Regression and sandbox testing uses different infrastructure than production. Development uses infrastructure that is separate from production.

What is the process of combining a series of automation steps into a repeatable process that can be audited? A. Automation B. Orchestration C. Autoscaling D. Patching

B. Orchestration is the combination of separate automation tasks. Automation is what we are trying to combine. Autoscaling can be orchestrated but is specific. Patching should be automated but is also too specific.

You are designing the infrastructure for an e-commerce website that plans on selling sporting apparel for football (soccer) clubs around the globe. Which technology should you look at that offers the lowest latency and best performance for your shoppers? A. Immutable infrastructure B. Synchronous replication C. Content delivery network D. Autoscaling

C. A CDN will offer lower latency around the globe. Immutable infrastructure should be used but does not offer any of the requirements. Synchronous replication cannot be used around the globe. Autoscaling should also be used but does not offer any of the requirements.

What storage type is used for the OS boot partition of an instance running in the cloud? A. HDD B. File C. Block D. Object

C. Block storage is the storage type used for all OS boot partitions. File and object storage can be used in an instance, but due to their shared nature, neither one can be used as a boot partition. HDD is a type of block storage, but so is SDD. It might be the underlying technology.

Your legal department wants to start using cloud resources. However, since all of their work will be associated with legal cases, they need an accurate usage and billing breakdown to bill the clients. What are you being asked to implement? A. Right-sizing B. Maintenance C. Chargebacks D. Monitoring

C. Chargebacks is the process of creating the tags needed to provide accurate and detailed billing to be able to bill a third party. Right-sizing deals with the process of moving to the cloud. Maintenance is services that are purchased from third parties. You can set up an alert or monitoring for billing, but that is not specific to the question.

Which of the following is not a common characteristic of public clouds? A. Self-service B. Pay-as-you-go C. Higher cost D. Availability

C. Cloud services should lower the cost of network operations and software use for companies. Cloud characteristics include elastic, self-service, scalability, broad network access, pay-as-you-go, and availability.

What has become synonymous with DevOps and is referred to as a pipeline and used in the real world by organizations? A. Continuous integration continuous diversity B. Continuous integration continuous development C. Continuous integration continuous delivery D. Continuous integration continuous discovery

C. Continuous integration continuous delivery (CI/CD) is the pipeline that is used in the real world. Continuous integration and continuous deployment are used but not in the real world because of the impact on user experience. Options A and D are not real terms.

You need to update all the Windows Servers from Server 2012 R2 to Server 2016. You decide the best course of action is to do an in-place upgrade and install Server 2016 over the top of Server 2012 R2. Is this a recommended course of action? Why or why not? A. Yes, because you are saving money by not creating more servers. B. Yes, because the software is already installed on the servers and you know Server 2016 is compatible. C. No, because you are not treating the servers as disposable resources. D. No, because you have not performed any load testing of the software on Server 2016.

C. No, because you are performing an in-place upgrade, which goes against the concept of disposable resources. Option A may save costs temporarily but has increased risk with an on-prem upgrade. Option B is not correct because Server 2016 being compatible is not enough. You have not performed any testing. D is not correct because the reason for No is not sufficient; load testing is not testing the upgrade process.

The CIO wants to cut the cost of the instances that are running in the cloud. The instances that have the highest cost are all production instances and are required to be on 24/7. Which instance type should you look into utilizing? A. On-demand B. Spot C. Reserved D. Quick

C. Since the instances are production and required, reserved is the most cost effective. On-demand is the most expensive option. Spot is the cheapest, but is not designed for production instances. Quick is not a type of instance.

Your manager wants to do a lift-and-shift migration from on-premises servers to cloud servers. He has determined that the cloud will save money. Which process is the manager forgetting to complete? A. Templating B. Autoscaling C. Orchestrating D. Right-sizing

D. Right-sizing is the process of evaluating current on-premises servers for need and sizing before moving to the cloud. Templating is used for provisioning servers. Autoscaling is sizing resources in the cloud. Orchestrating is part of configuration management once already in the cloud.
