Answers to Assessment Test 1. In the shared responsibility model, the CSP is responsible for security of the cloud, which includes services and infrastructure such as compute and storage resources. Clients are responsible for security in the cloud, such as operating systems, access management, and customer data.

See Chapter 1 for more information. The software as a service SaaS model provides software applications, including apps such as Google Docs, Microsoft Office , and Gmail. Infrastructure as a service IaaS offers hardware for compute, storage, and networking functionality.

Platform as a service PaaS provides development platforms for software developers. There is no commercial cloud deployment model. Private clouds are owned and used by one company and not sold to others. A hybrid cloud is both public and private. Scalability can refer to the ability for cloud services to be scaled geographically. Users from multiple global locations can access resources. Self-service means the ability to add resources without supplier intervention.

Broad network access means that various client devices with different operating systems can access resources. Shared responsibility is a model that defines and enhances cloud security. High availability models are specified in terms of nines.

More nines guarantee more uptime but also cost more. Therefore, five nines will cost more than four nines, which will cost more than three nines.

The client is responsible for defining the recovery point objective RPO , which is the maximum age of files that must be recovered from backups in order to restore normal operations, and the recovery time objective RTO , which is how long the CSP has to get everything operational, including network access and data restoration, in the event of a disaster. Deduplication saves storage space by removing redundant copies of files. Compression also saves space but does it by removing redundancy within a file.

Capacity on demand is when a client can get more storage space instantaneously. Block storage is a storage type. See Chapter 2 for more information. Object storage is the best option for unstructured data. Block storage is good for databases, storage area networks, and virtual machines.

Cold storage means the data is offline. The Remote Desktop Protocol is used to remotely manage Windows-based servers. Cold storage will always be less expensive than hot storage. Object and block storage are ways to store files, but either can be hot or cold. A firewall is a network- or host-based security device. It can help protect a network or individual computers from malicious network traffic. Load balancing means spreading work across multiple servers.

Software-defined networking SDN makes networks more agile and flexible by separating the forwarding of network packets the infrastructure layer from the logical decision-making process the control layer. SDN abstracts network hardware in the cloud.

A content delivery network does load balancing for websites. Software-defined storage SDS allows for the virtualization of cloud storage solutions. D, C, B, A. The first step in a cloud assessment is to determine current and future requirements. Then, run a baseline, followed by a feasibility study, then gap analysis, then use reporting, and then compare to benchmarks.

Finally, create documentation and diagrams. See Chapter 3 for more information. Linked home appliances and smart thermostats are examples of technologies that rely upon the Internet of Things IoT. Virtual desktop infrastructure VDI creates virtual user desktops. Single sign-on SSO is a security mechanism for computer logins. Artificial intelligence is when computers perform complex, human-like tasks.

Key stakeholders are important people with a vested interest in something. In this case, the chief executive officer CEO , chief information security officer CISO , and department manager could all be key stakeholders. The cloud service provider CSP is not a key stakeholder who should have input on which cloud services you need.

They can make suggestions, but their role is to sell you services. Machine learning ML , which is a general form of artificial intelligence AI , uses probabilities to make predictions about classifying new input based on previous input it received.

Autonomous environments are when machines perform complex, human-like actions without human intervention. Microservices is a way to speed up app development and lower costs.

Blockchain operates on three key principles: decentralization, transparency, and immutability. No one organization owns the blockchain, and the information is stored on all participating nodes. Therefore, there is decentralization and transparency. The data is also hard to hack, which gives it immutability. While the user IDs are securely hashed in blockchain, there is no anonymity. Virtual desktop infrastructure VDI is for creating virtual user desktops on a server.

It is not related to identity access management IAM. A pilot is a small-scale evaluation deployment in the production environment. You would not do that before an RFI. See Chapter 4 for more information. Lift and shift, where data and applications are picked up as is and moved to another location, is the quickest and cheapest migration option.

In a rip and replace, software needs to be redeveloped to take advantage of cloud services. A hybrid is a combination of the two, or a migration where some items stay in the original location. Phased migrations happen over time. A PoC is an evaluation used to prove that a technology works as it should. A proof of value PoV is run to see whether cost savings can be realized. Managed services are professional services used to support cloud installations. A pilot is a small-scale initial rollout of a solution into the production environment.

Training is a short-term activity that focuses on acquiring a specific skillset to perform a job. Support and managed services are professional services that you might buy to help support the cloud. Professional development refers to a long-term educational process focused on employee growth. Purchasing IT hardware or other tangible assets is a capital expenditure.

Switching to a cloud-based IT infrastructure model with pay-as-you-go pricing means less or no need to purchase hardware and therefore no new capital expenditures. BYOL licenses can be permanent or subscription-based. Depreciation timelines are for capital expenditures only. Bring your own license BYOL is when software can be transferred from one user to another or from one system to another.

Subscriptions might or might not qualify as BYOL. Pilots and proof of concepts PoCs are types of evaluations. Under a subscription-based model, users should have device flexibility, meaning that only one license per user is required.

Therefore, you need 10 licenses. The four teams involved in the CICD pipeline do not communicate or collaborate with each other. Regions, zones, and networks are terms that are not specific to the CICD pipeline. See Chapter 5 for more information. Locality is the measure of the distance between data and the end user. This distance directly impacts the latency between the two.

Provisioned is a state of an instance. Replication can affect latency but does not determine it. Data availability is a property of data and the availability. The Linux kernel is licensed under the GPL, which is a free-for-use license. Pay for use is a license type, but the Linux kernel is free.

C and D are not license types. Synchronous replication keeps data synced in real time. Asynchronous replication eventually keeps data consistent. Autoscaling and Reserved are not types of replication. Backups are the copying of data to a different location in the event of data loss or corruption. Replication does not copy snapshots.

Geo-redundancy does copy data, but the source can still be lost or corrupted. Object storage is where backups are usually copied to. Immutable means that the data cannot be modified or changed. B, C, and D are all properties that are changeable. Qualitative analysis is the analysis of a value of an asset based on its perceived value.

In contrast, quantitative analysis is the analysis of the monetary value of an asset based on monetary value. See Chapter 6 for more information. Quantitative analysis is the analysis on of a value of an asset based on monetary value or its quantity. In contrast, qualitative analysis is the analysis of the value of an asset based on its perceived value.

While the other choices may be assets and potential threats, they are all specific. Risk is the probability or likelihood of a threat against an asset. The two identified owners are the risk and asset owners.
