Security, Compliance, Privacy and Trust (10 questions)

  1. Question 1

    Which identity service in Microsoft 365 manages user identities, sign-in and access to applications for an organisation?

    1. AMicrosoft Exchange Online, which hosts mailboxes and does not manage identity or sign-in
    2. BMicrosoft Entra ID, which manages identities, sign-in and access to applications
    3. CMicrosoft SharePoint, which hosts sites and documents and does not manage identities centrally
    4. DMicrosoft Teams, which provides collaboration and does not manage identity for the organisation
    Show answer and explanation
    Correct answer: B

    Microsoft Entra ID manages identities, sign-in and application access. Exchange, SharePoint and Teams do not manage identity centrally.

  2. Question 2

    Which feature requires users to confirm their identity with a second factor when signing in to Microsoft 365?

    1. AA shared account used by the whole team, with one password known to all members of the team
    2. BA longer password policy that requires twenty characters, with no second factor required at all
    3. CMulti-factor authentication, which requires a second factor in addition to the password
    4. DRemembering the last device used, so that the user is not asked to sign in again on that device
    Show answer and explanation
    Correct answer: C

    Multi-factor authentication requires a second factor in addition to the password. A longer password, a shared account and device memory do not add a second factor.

  3. Question 3

    Which capability controls access to resources based on conditions such as user location, device health or risk level?

    1. AConditional Access policies in Microsoft Entra ID, which apply rules based on conditions
    2. BSensitivity labels, which classify content and apply protection but do not control sign-in conditions
    3. CRetention policies, which control how long content is kept rather than who can sign in
    4. DMicrosoft Forms settings, which control who can answer surveys rather than who can access resources
    Show answer and explanation
    Correct answer: A

    Conditional Access applies rules based on location, device health and risk. Sensitivity labels, retention policies and Forms settings control different things.

  4. Question 4

    Which Microsoft 365 feature classifies documents and emails and applies protection such as encryption or access restrictions?

    1. AForms templates, which provide reusable survey structures for collecting responses from participants
    2. BTeams channels, which group conversations and files by topic for the members of each team
    3. CPlanner boards, which show task progress and assignments for each plan the team manages
    4. DSensitivity labels, which classify content and apply protection automatically or manually
    Show answer and explanation
    Correct answer: D

    Sensitivity labels classify content and apply protection such as encryption. Teams channels, Planner boards and Forms templates do not classify or protect content.

  5. Question 5

    Which Microsoft 365 capability helps prevent sensitive information, such as card numbers, from being shared outside the organisation?

    1. AMicrosoft Bookings, which schedules appointments and does not inspect content for sensitive information
    2. BRetention labels, which control how long content is kept and do not detect sensitive information in sharing
    3. CData loss prevention (DLP) policies, which detect and act on sensitive information in content and sharing
    4. DMicrosoft Lists, which tracks items in lists and does not monitor sharing for sensitive information
    Show answer and explanation
    Correct answer: C

    DLP policies detect and act on sensitive information in content and sharing. Retention labels, Bookings and Lists do not prevent leakage of sensitive data.

  6. Question 6

    Which tool helps an organisation find and export content in Microsoft 365 for a legal investigation?

    1. AMicrosoft Forms responses, which are stored in the form and cannot be searched across the tenant
    2. BMicrosoft Teams chat, which lets users search their own messages but cannot preserve or export content for a case
    3. CeDiscovery in Microsoft Purview, which searches and preserves content for legal cases
    4. DMicrosoft Planner boards, which show tasks and their status but do not hold legal content for export
    Show answer and explanation
    Correct answer: C

    eDiscovery in Microsoft Purview searches, preserves and exports content for legal cases. Chat, Forms and Planner do not provide that case-management function.

  7. Question 7

    Which Microsoft 365 tool gives an organisation a score and recommended actions to improve its compliance with regulations?

    1. AMicrosoft Planner, which tracks tasks and plans and does not assess the regulatory position
    2. BMicrosoft Bookings, which schedules appointments and does not assess regulatory compliance
    3. CMicrosoft Forms, which collects survey responses and does not assess the organisation's compliance
    4. DCompliance Manager in Microsoft Purview, which scores compliance and recommends improvement actions
    Show answer and explanation
    Correct answer: D

    Compliance Manager scores compliance and recommends actions. Bookings, Forms and Planner do not assess compliance posture.

  8. Question 8

    Which admin centre is used to manage Microsoft 365 user licences and accounts?

    1. AThe Teams chat settings page, which controls how each user receives messages in chat
    2. BThe Microsoft 365 admin center
    3. CThe Forms themes page, which controls the colours and layout of surveys for participants
    4. DThe Planner boards list, which shows the tasks each person is assigned in each plan
    Show answer and explanation
    Correct answer: B

    The Microsoft 365 admin center manages users, licences and accounts. Teams chat settings, Forms themes and Planner boards do not manage licences or accounts.

  9. Question 9

    Which two practices help protect an organisation's Microsoft 365 accounts from compromise? (Choose two.)

    1. AEnable multi-factor authentication for all users, with stronger methods for administrators
    2. BShare administrator passwords across the IT team, so that access is never delayed by a missing person
    3. CAllow legacy authentication protocols for all users, since older applications depend on them
    4. DGive every user global administrator rights, so that users can recover their own accounts quickly
    5. EUse Conditional Access to block risky sign-ins and require compliant devices for sensitive apps
    Show answer and explanation
    Correct answer: A, E

    MFA for all users and Conditional Access against risky sign-ins protect accounts. Shared admin passwords, legacy protocols and global admin for every user each weaken protection.

  10. Question 10

    Which two features help an organisation manage how long its Microsoft 365 content is kept? (Choose two.)

    1. ARetention policies that keep or delete content for set periods across services
    2. BSensitivity labels that colour the document header, so that readers can see how old the content is
    3. CRetention labels applied to individual items, which keep or dispose of them after a defined period
    4. DMicrosoft Bookings settings, which control how long appointments remain visible in the calendar
    5. EMicrosoft Forms themes, which control the layout of surveys shown to participants each time
    Show answer and explanation
    Correct answer: A, C

    Retention policies and retention labels control how long content is kept and when it is disposed of. Sensitivity labels, Bookings settings and Forms themes do not manage retention.

Cloud Concepts (10 questions)

  1. Question 21

    A company wants to move from owning servers in its own data centre to renting computing resources on demand from a provider. Which cloud benefit does this describe?

    1. ACapital expenditure is replaced by operational expenditure, paid as resources are used
    2. BFull control over the physical data centre, including the choice of every rack and cable
    3. CA fixed monthly cost regardless of usage, locked in for the duration of a five-year contract
    4. DOwnership of all hardware, which is depreciated over the expected life of each server
    Show answer and explanation
    Correct answer: A

    Cloud computing shifts spending from capital to operational expenditure, paid as resources are used. Owning the data centre, fixed monthly costs and hardware depreciation describe on-premises models.

  2. Question 22

    Which cloud model provides a company with dedicated infrastructure that it operates in its own facility?

    1. APrivate cloud, which is operated for a single organisation
    2. BPublic cloud, which is shared by many customers on the provider's infrastructure
    3. CCommunity cloud, which is shared by a group of organisations with common requirements
    4. DHybrid cloud with no on-premises component, which runs entirely in a public provider's data centres
    Show answer and explanation
    Correct answer: A

    A private cloud is dedicated to one organisation, which may run it in its own facility. Public and community clouds are shared, and a cloud-only hybrid is not a hybrid model.

  3. Question 23

    A company uses Microsoft 365 for email and documents, and runs a legacy line-of-business application on its own servers. Which model best describes this arrangement?

    1. AHybrid cloud, combining cloud services with resources kept on premises
    2. BPublic cloud only, since any use of a cloud service makes the whole estate public cloud
    3. CPrivate cloud only, since Microsoft 365 is operated for the company alone and not shared
    4. DOn-premises only, since the cloud services are used only for email and documents by staff
    Show answer and explanation
    Correct answer: A

    Combining cloud services with resources kept on premises is a hybrid model. Calling it public or private only, or on-premises only, ignores one of the two parts.

  4. Question 24

    Which service model gives customers the most control over the operating system and applications, while the provider manages the underlying infrastructure?

    1. AInfrastructure as a service (IaaS), where the customer manages the operating system and applications
    2. BSoftware as a service (SaaS), where the provider manages the application and most of the stack for the customer
    3. CPlatform as a service (PaaS), where the provider manages the operating system and runtime for the customer
    4. DFunction as a service without any servers, where the customer has no control over the code execution
    Show answer and explanation
    Correct answer: A

    IaaS gives customers control over the operating system and applications while the provider manages infrastructure. SaaS and PaaS give the provider more management, and the last option describes no control at all.

  5. Question 25

    Which cloud characteristic allows an organisation to add capacity quickly when demand rises and remove it when demand falls?

    1. AImmutability, which prevents resources from being changed once they have been provisioned
    2. BFixed capacity, which keeps the same number of resources regardless of how much work arrives
    3. CDedication, which reserves a fixed set of hardware for one customer for the duration of the contract
    4. DElasticity, which scales resources up and down with demand
    Show answer and explanation
    Correct answer: D

    Elasticity scales resources with demand. Fixed capacity, dedication and immutability describe the opposite or different characteristics.

  6. Question 26

    Which term describes a cloud service that users access through a web browser without managing any underlying infrastructure?

    1. ACo-location, where the organisation rents rack space and manages its own servers
    2. BInfrastructure as a service (IaaS)
    3. COn-premises hosting, where the organisation runs every server in its own building
    4. DSoftware as a service (SaaS)
    Show answer and explanation
    Correct answer: D

    SaaS is accessed through a browser with no infrastructure management. IaaS leaves infrastructure management to the customer, while on-premises hosting and co-location both require the organisation to run servers.

  7. Question 27

    Which two benefits are typical of moving workloads to a public cloud? (Choose two.)

    1. AReduced need for upfront hardware purchases, with costs tied to usage
    2. BGuaranteed zero downtime, since the provider never has any outage in any Region
    3. CFull physical control of every server in the provider's data centre by the customer
    4. DFaster access to new capabilities, since the provider updates services regularly
    5. EA requirement to manage the physical security of the provider's data centres
    Show answer and explanation
    Correct answer: A, D

    Public cloud reduces upfront hardware spending and gives faster access to updated services. Zero downtime is not guaranteed, customers do not control provider hardware, and physical security is the provider's responsibility.

  8. Question 28

    A company wants a cloud service that lets its developers deploy applications without managing the operating system or the underlying servers. Which model fits best?

    1. AOn-premises hosting, where the company manages the operating system and the servers itself
    2. BInfrastructure as a service (IaaS), where the customer manages the operating system and the servers
    3. CPlatform as a service (PaaS), where the provider manages the platform and the customer manages the application
    4. DCo-location, where the company rents rack space and installs its own servers in the facility
    Show answer and explanation
    Correct answer: C

    PaaS removes the management of the operating system and servers while the customer manages its applications. IaaS, on-premises and co-location all leave server management with the customer.

  9. Question 29

    Which Microsoft cloud resource is used to organise related Azure resources so that they can be managed, secured and billed together?

    1. AA Microsoft Planner plan, which tracks tasks for a team but does not organise cloud resources
    2. BA Microsoft Forms survey, which collects answers from respondents about the cloud services they use
    3. CA resource group, which holds related resources for management and access control
    4. DA Microsoft Teams channel, which groups conversations and files for members of a team
    Show answer and explanation
    Correct answer: C

    A resource group organises related resources for management and access control. Forms, Planner and Teams channels are collaboration tools rather than cloud resource containers.

  10. Question 30

    Which feature of cloud platforms keeps copies of data in more than one physical location, so that data survives the loss of one location?

    1. ARedundancy, which stores copies of data across multiple locations for durability
    2. BElasticity, which adds and removes compute capacity as demand changes over time
    3. CMetering, which records usage so that the customer can be billed for what was consumed
    4. DVirtualisation of the desktop, which runs user sessions on shared servers for remote access
    Show answer and explanation
    Correct answer: A

    Redundancy stores copies across locations, which improves durability and availability. Elasticity, metering and desktop virtualisation serve other purposes.
