Chapter 3 - Quiz
The sales team needs to find better, faster, and cheaper ways to engage with potential customers. Which cloud service should they implement? A. Digital marketing B. Big data C. Blockchain D. Identity access management
A. Digital marketing is when companies market products or services using digital technology. Examples include email campaigns and social media posts. Big data refers to unstructured data. Blockchain is a secure transaction ledger. IAM refers to capabilities used to authenticate users.
Company A has a software development team with members located in Geneva and others in Chicago. Which cloud service will best help them manage a project that all of them are working on? A. Collaboration B. Self-service C. Autonomous environment D. Blockchain
A. For the team to work together better, they should use collaboration software. Using it, they can video conference and share files with ease. Self-service refers to getting more cloud resources without CSP intervention. An autonomous environment is one in which human intervention is not needed, such as a self-driving car. Blockchain is a secure ledger system.
When setting up a new cloud service, you want to ensure that you can get more storage space quickly without needing to call or email the CSP. What cloud service allows you to do this? A. Self-service B. SSO C. Subscription service D. Autonomous service
A. Self-service means clients can get more cloud resources automatically without CSP intervention. SSO is a security mechanism. Subscription service is when a company pays for a level of services for a specified period of time. Autonomous environments are when computers or machines perform complex human-like actions without human intervention.
You have been asked to perform a cloud assessment for your company. Which of the following describes an appropriate order for conducting assessment tasks? A. Contact key stakeholders, run a baseline, perform a gap analysis, create documentation. B. Run a baseline, contact key stakeholders, perform a gap analysis, create documentation. C. Create documentation, run a baseline, perform a gap analysis, contact key stakeholders. D. Perform a gap analysis, run a baseline, contact key stakeholders, create documentation.
A. The first thing to do when conducting a cloud assessment is to determine current and future requirements, and you do so by contacting key stakeholders and asking the right questions. After that, you can run a baseline to see where current performance is. That will let you perform a gap analysis to understand where the business and technical situations fall short. Finally, at the end you will create documentation and diagrams.
Your company recently merged with another, and the networks have been combined into a cloud solution. Users need to access multiple resources from different systems within the same security domain. What should your company implement to make access as easy as possible for users? A. SSO B. Federation C. MFA D. Self-service
A. The purpose of SSO is to give users access to all of the systems, resources, and apps they need with one initial login. Federation is like SSO but applies across security domains. MFA means that users need to provide multiple pieces of information to log in—it makes access harder, not easier. Self-service refers to getting more cloud services without CSP intervention.
Company A wants to assess the possibility of migrating to the cloud. What should they do to determine how much of their current server storage capacity is being used? A. Run a benchmark. B. Run a baseline. C. Determine current and future requirements. D. Run a gap analysis.
B. A baseline tells the company how its systems are currently performing. A benchmark compares performance numbers to an established standard or point of reference. Determining current and future requirements tells you what is needed but does not tell you about current performance. A gap analysis helps determine what gaps exist between current performance and desired performance standards.
You are performing a cloud assessment for your organization. It's time for you to determine which capabilities can be offloaded to the cloud and the level of support services needed. Which of the following assessments should you perform? A. Gap analysis B. Feasibility study C. Baseline D. Current and future requirements
B. A feasibility study can help determine whether it's possible for a company to move to the cloud. This includes determining which capabilities can be offloaded to the cloud as well as the level of support services needed. A gap analysis tells a company what the gap is between their current levels of business or technical readiness and where they need to be. A baseline is a measure of current performance. Determining current and future requirements is done before figuring out what can be offloaded or what support is needed.
Your company is debating which cloud-based data analytics solution to implement. Which of the following statements is NOT true when comparing AI to ML? A. AI can only react to conditions it's been programmed to react to. B. ML is a form of applied AI. C. ML uses neural networks. D. AI is when machines perform smart, human-like activities.
B. ML is a form of general AI, not applied AI. Applied AIs are designed to perform a specific, smart, human-like activity. And, AIs can only react to conditions they have been programmed to react to. ML learns through the use of neural networks.
Your company is trying to save money by using cloud services. Which of the following is most likely to help reduce the costs of software development? A. Federation B. Microservices C. ML
B. Microservices describes the breaking down of a larger program into smaller pieces— literally small services. It can reduce the cost of software development and ownership. Federation is a security mechanism. Machine learning (ML) and artificial intelligence (AI) are two services that can help with data analytics.
A small company needs to set up a security surveillance system to protect its building. Which cloud-based technology will the security system most likely take advantage of? A. VDI B. IoT C. SSO D. AI
B. Security systems are an example of a technology that relies upon the Internet of Things (IoT). VDI creates virtual user desktops. SSO is a security mechanism for computer logins. AI is when computers perform complex, human-like tasks.
The company CIO approaches you and asks you if the company should implement blockchain in the new cloud environment. Which of the following is the best explanation you can give on what blockchain is? A. It's an online cryptocurrency. B. It's an authentication system that securely validates users. C. It's a secure, open, distributed ledger. D. It lowers the TCO for application DevOps.
C. Blockchain is an open, distributed ledger that can securely record transactions between two parties in a verifiable and permanent way. The most famous example of blockchain usage is for the cryptocurrency Bitcoin, but Bitcoin and blockchain are not the same thing. Blockchain is not an authentication system, nor does it lower the TCO for application DevOps.
Your company recently signed up for a Microsoft Office 365 subscription. The network administrator wants to make it so that users only have to type in their login information once and don't need to log into the local network and Microsoft's cloud separately. What service does she need to implement? A. SSO B. Self-service C. Federation D. MFA
C. Federation allows users to perform a single sign-on across different companies' security domains, whereas single sign-on refers to users logging into multiple systems within the same security domain. In this case, since it's the company's local network and Microsoft's cloud, it will be federation. Self-service refers to getting more cloud resources without CSP intervention. Multifactor authentication (MFA) means that users need to provide more information besides a username and password to log in, such as a temporary security code.
To increase security of your company's cloud resources, the administrator decides to require users to enter a password and also a randomized security code to log into the cloud. What cloud service does the administrator need to enable? A. SSO B. VDI C. MFA D. Federation
C. Requiring users to enter multiple pieces of information to be authenticated is called MFA. SSO requires a username and password and allows access to multiple resources within a security domain. VDI is for creating virtual user desktops on a server. Federation is like SSO, but for across organizations.
You are performing a cloud assessment. What is the final step to take in the cloud assessment process? A. Engage key stakeholders B. Run a feasibility study C. Create documentation and diagrams D. Perform a gap analysis
C. The final thing to do in a cloud assessment is to ensure that documentation and diagrams have been created. Conversations with the key stakeholders and CSP should be documented. Service coverage and locations should be diagrammed as needed. Engaging key stakeholders should happen very early in the process, as should feasibility studies and gap analyses.
A network administrator wants to implement VDI in your future cloud solution. Which of the following is NOT an implication of implementing VDI? A. Centralized administration B. Remote user access C. Higher costs D. Increased security
C. Virtual desktop infrastructure (VDI) is when user desktops are created inside a virtual machine (VM) located on a server. VDI can centralize administration, increase security, and allow users to access their desktops remotely. VDI most often reduces the total cost of ownership and does not result in higher costs.
A network administrator who is part of the cloud assessment team mentions that the average server CPU utilization is at 40 percent. What do you use to determine if this is acceptable performance? A. Baseline B. Technical gap analysis C. Compute reporting D. Benchmark
D. A benchmark is a standard or point of reference for comparison. It should be used to determine whether performance is acceptable. A baseline can give you a performance read but doesn't provide context. A technical gap analysis will help you determine whether the company has the technology needed to implement cloud services or what is needed to do so. Compute reporting will give you CPU and RAM utilization from the CSP.
A software developer at your company said he just used the cloud to place his program and all needed library files into one package. Which cloud service is he referring to? A. Microservices B. Blockchain C. Federation D. Containerization
D. Containerization is a fancy term meaning that all items are placed into a container. Developers can do this with a program they have created along with all components needed to execute that program. Microservices is a way to build apps by breaking them into smaller components. Blockchain is a secure digital ledger. Federation is a security mechanism.
In preparation for a cloud migration, your manager asks you to run a gap analysis. Which of the following is NOT a likely outcome of a gap analysis? A. Understanding if there are compatibility issues with software in the migration plan B. Identifying policies that are not being met by the migration plan C. Prioritizing allocation of resources within the migration plan D. Determining key stakeholder feedback about the migration plan
D. Key stakeholders should input into a cloud assessment, but their feedback is particularly valuable when gathering current and future requirements. A gap analysis can be technical, business-related, or both. A gap analysis can help find compatibility issues, policies that are not being met, and priority calls that need to be made.
A member of your company's purchasing team is negotiating cloud services with a CSP. Over the course of the first year, which of the following would likely represent a cost savings over other types of payment models? A. Pay-as-you-go B. Self-service C. High availability D. Subscription services
D. Subscription-based pricing, or subscription services, usually offers a discount over payas-you-go models, but it also means your company is locked into a contract for the length of the subscription. Self-service refers to being able to get more cloud resources without CSP intervention. High availability is a feature of clouds (and more guaranteed availability will cost more), but it is not a cloud payment model.
One of the company's developers is creating a software package that can identify human faces and mine footage from security cameras to determine whether someone is suspected of a crime. Which type of technology is best suited for this task? A. Big data mining B. Blockchain C. AI D. ML
D. With ML, data can be fed to a computer, and it will learn from it and adapt. ML is a specialized form of AI and is perfect for facial recognition programs. Big data refers to unstructured data; mining it could help find data or data patterns. Blockchain is a secure ledger system. AI can make human-like decisions, but it can't learn, which is needed for facial recognition.
