Exam SY0-601 topic 1 question 93 discussion

I think this is one of those questions where real-life experience doesn't answer the question correctly here. The question seems to be focusing more on which form of cloud computing requires the LEAST amount of management (SaaS) with the database part of the question being filler.

If they have 100 databases they need to migrate, then they will need a Platform. I don't see how the SaaS model can help with migrating databases to the cloud.

PaaS is the right service for database platforms.

Infrastructure as a Service is building out a network (Moving your servers) to the cloud.

C. PaaS (Platform as a Service) In a PaaS model, the cloud provider manages not only the underlying infrastructure but also the runtime, middleware, and development tools required to run applications. When migrating databases to a PaaS environment, the cloud provider handles tasks such as provisioning, scaling, patching, and backups, reducing the management and support burden on the company significantly. With PaaS, the company can focus on deploying and managing its databases and applications without worrying about the underlying infrastructure or the operational tasks associated with maintaining databases. This approach allows the company to leverage the expertise and resources of the cloud provider, resulting in reduced management overhead and improved operational efficiency. Therefore, PaaS would be the best choice for minimizing management and support efforts in migrating databases to the cloud.

Given the scenario and the need to migrate sreverfs to the cloud while minimizing managemetn and support, the best option woud be PaaS. That being said, these questions not only test your knowledge, but your hability to guess the mind of the person who wrote the question. For example, in this cases you have to ignore the context that was said at the beggining and only focus the question. But sometimes you have to take into considiration the context. How do you know when to take the context into condiration and when not? Well you don't, you just have to follow yoru instints sometimes.

I salute you, guys. Firstly I want to thanks this site and his community for the help offered. I scored 767. I think I had 50% of this questions with the exact order of the answers, but I highly recommend to search for your own good and participate in discussions. You can do it guys, I believe in you all of you.

While A requires the least management and support (for everyone), it's the wrong answer, in the context of the question. In the question, the company is looking to migrate servers, not applications. SaaS is ready built applications, which means you cannot change the way it works, cannot move corporate apps or dbs over, or anything like that. They wish to do so, and, in PaaS, the infrastructure is already there (the "technology footprint" = hardware).

A paas is for development and since client have data, a SaaS is the best for third party to managed the data.

In the context of hosting database servers in the cloud, using PaaS offerings like RDS, SQL Database, or Cloud SQL would provide a more managed and streamlined experience compared to setting up and managing database servers on IaaS platforms. This will fill the requirement of "least management and support".

SaaS does not do servers. Migrating servers and choosing SaaS are not compatible, as SaaS by definition involves using a vendor's cloud-based software applications, not migrating your own servers and databases. If the company wants to migrate their servers to the cloud, their options would fall under either Iaas or PaaS:

https://hypertecsp.com/knowledge-base/cloud-migration/ IaaS – Is best for companies that don’t mind hosting their applications in third-party data centers but instead would prefer to outsource the care of their physical infrastructure to concentrate more completely on developing, deploying, and monitoring. PaaS – Robust and portable, PaaS platforms provide a full (and invisible) infrastructure environment. Adopting a PaaS solution will also reduce your ready-to-market timings – since PaaS will be pre-loaded with most of the run-time required software. SaaS – Is a delivery model through which centrally hosted productivity software is licensed on a subscription basis. IaaS: Infrastructure as a Service (AWS, Azure, Google Cloud Platform, Alibaba Cloud) PaaS: Platform as a Service (AWS Elastic Beanstalk, Heroku, Google App Engine, Engine Yard) SaaS: Software as a Service (Google G Suite, Office 365, Salesforce, NetSuite)

Keyword is databases.

Took the exam today and passed with a 775. About 90% of the questions are from this dump. This dump was worth the $39.0 This question was exam. This question was in the test.

This one is tricky, but if you think of it, they are migrating servers, not just the data, which tells me they intend to provision new instances in the cloud to host their data. That looks like PaaS to me hence C

if you check out the definition of SaaS, I dont really know how that is an answer in migrating 100 databases and servers to the cloud.

here is a quote from CompTIA study guide. The most recent : ,, Platform as a Service Platform as a service (PaaS) provides resources somewhere between SaaS and IaaS. A typical PaaS solution would provide servers and storage network infrastructure (as per IaaS) but also provide a multi-tier web application/database platform on top. This platform could be based on Oracle or MS SQL or PHP and MySQL. Examples include Oracle Database (oracle.com/database), Microsoft Azure SQL Database (azure. microsoft.com/services/sql-database), and Google App Engine (cloud.google.com/ appengine). As distinct from SaaS though, this platform would not be configured to actually do anything. Your own developers would have to create the software (the CRM or e‑commerce application) that runs using the platform. The service provider would be responsible for the integrity and availability of the platform components, but you would be responsible for the security of the application you created on the platform. " SO reading this i think this debate is closed. The answer is SaaS although in practice things are a little more different.
