4.1 · Recall

1. What mainly distinguishes IaaS from SaaS?

In IaaS you manage the OS and above; in SaaS you use a turnkey application IaaS is reserved for large companies, SaaS for small organisations SaaS is accessible only offline, IaaS always online IaaS is free to use, SaaS is paid by monthly subscription

The models differ by what you manage: the OS and above in IaaS, almost nothing in SaaS (turnkey application).

2. An SME with no IT person wants messaging and office productivity with nothing to maintain. Which model?

IaaS, to keep control of each operating system SaaS, a turnkey application such as Microsoft 365 PaaS, to deploy and administer the technical foundation yourself None: this need does not fall under the cloud

SaaS is the turnkey application used directly: nothing to maintain, ideal for an SME with no IT person.

4.1 · Arbitration

3. Sofiane hesitates between IaaS and SaaS for a standard business service. What does he weigh?

The per-use price, always lower in IaaS than in SaaS The colour of the chosen provider's interface What you want to manage or not, and vendor dependence The number of employees of the client company

The right model depends on what you want to manage or not; vendor dependence and per-use cost are the arbitration criteria.

4.2 · Recall

4. Without a licence assigned, can a Microsoft 365 user access the applications?

Yes, all applications remain accessible by default Yes, but only to the Office productivity applications Yes, during a one-month automatic trial for each account No: without a licence assigned, they have no access to the applications

Without a licence assigned, the account does not give access to the applications: the licence is the right of use.

4.2 · Application

5. An employee leaves the SME. Which sequence does Sofiane apply?

Block sign-in, archive the mailbox then recover the licence Delete the account and its mailbox on the last working day Leave the account active, just changing its password Reassign the licence and delete all the site's data

You block then archive before deleting: the data is preserved and the paid licence is recovered.

4.2 · Arbitration

6. A manager and a field role do not have the same needs. What does Sofiane recommend?

Give everyone the most complete licence to avoid problems Choose the plan suited to each profile and track licences Buy the licences at random then adjust at year-end Licence nobody and let everyone use their personal account

A licence suited to each profile and regular tracking prevent the budget leak of unused licences.

4.3 · Recall

7. What corresponds to a Microsoft 365 user's personal file space?

SharePoint, the shared file space of the whole team Teams, the collaboration tool through channels and meetings OneDrive, the user's personal file space Exchange, the tenant's messaging service

OneDrive is the personal space; SharePoint is the team space and Teams the collaboration tool.

4.3 · Application

8. Sofiane wants to set the rights of a Teams channel. Where does he actually act?

In the antivirus of each channel member's workstation Directly on the channel owner's computer In a shared Windows folder on the file server On the associated SharePoint site, which stores the files

The files of a Teams channel live in SharePoint: managing the channel's rights amounts to managing the associated SharePoint site.

4.4 · Recall

9. Which service manages Microsoft 365 identities in the cloud?

Entra ID (formerly Azure AD), Microsoft's cloud identity service SharePoint, which hosts sites and team spaces Exchange Online, the hosted messaging service The admin centre for licences and groups

Entra ID (formerly Azure AD) is the cloud identity service that manages Microsoft 365 accounts.

4.4 · Arbitration

10. An admin wants to exempt their privileged account from MFA to move faster. What do we say?

That is acceptable if the password is long and complex No: privileged accounts are protected as a priority It is pointless anyway, MFA is of no use It is possible, but only outside office hours

A compromised admin account gives the keys to the whole tenant: it is protected as a priority and never exempt from the rules.

4.5 · Application

11. On a host, Sofiane places three services as VMs. What is the benefit?

Each VM necessarily becomes faster than the whole server The physical hardware no longer needs to be backed up Optimising the hardware and isolating the services from one another Removing any need for an operating system on the VMs

Consolidation optimises the hardware and isolation partitions the services: an incident on one VM does not affect the others.

4.5 · Application

12. A light application must be deployed and scaled quickly. VM or container?

A VM, because each container demands a complete system A VM, because a container never shares the host OS Neither, this has nothing to do with virtualization A container, lighter and faster for scaling the application

The container is light and fast (it shares the host OS), ideal for deploying and scaling an application.

What's next?

Score ≥ 80%: move on to Level 5 — security & career development with Sofiane.
Score between 50% and 80%: review the section(s) you failed (4.1 cloud, 4.2 M365 administration, 4.3 collaboration, 4.4 identities, 4.5 virtualization), reread the course, then retake the test.
Score < 50%: reread the whole of level 4, applying each 48h challenge (classifying cloud services, writing the joiner/leaver procedure, mapping a collaborative space, hardening identities, consolidating servers) before trying again.
And after that? Keep your sheets (cloud classification, M365 procedure, collaboration map, identity security, consolidation): level 5 puts them to work for security and your development.
