1. 1What distinguishes on-demand self-service when consumers provision cloud computing resources?

   1. A.The consumer provisions resources automatically without provider staff interaction.Correct answer: A
   2. B.The consumer requests provider staff to provision resources for each change.
   3. C.The provider assigns resources only on a fixed schedule agreed in advance.
   4. D.The provider reserves a dedicated physical server for every consumer.

   Explanation: NIST says a consumer can provision computing capabilities "as needed automatically without requiring human interaction with each service provider." This is the distinguishing self-service characteristic; fixed schedules and dedicated hardware do not establish it.

   Reference: The NIST Definition of Cloud Computing — Section 2, Essential Characteristics, On-demand self-service

2. 2Which network device forwards traffic between a local cloud network and another IP network?

   1. A.A routerCorrect answer: A
   2. B.A layer 2 network switch
   3. C.A wireless access point
   4. D.A network intrusion detection sensor

   Explanation: Cloudflare describes a router as "a device that connects two or more packet-switched networks or subnetworks." A layer 2 switch forwards within a network, while an intrusion sensor and file server have other primary roles.

3. 3When a user opens a cloud web application, what does the browser normally send to the server to obtain a page?

   1. A.An HTTP requestCorrect answer: A
   2. B.An HTTP response
   3. C.A DNS response
   4. D.A TLS server certificate

   Explanation: MDN states that "The browser sends an HTTP request message to the server" to request the website. The server responds with the requested content when the request succeeds.

4. 4Which security objective addresses preventing unauthorized disclosure of cloud data?

   1. A.Availability of service
   2. B.Integrity of stored data
   3. C.Confidentiality of informationCorrect answer: C
   4. D.Authenticity of a source

   Explanation: NIST defines confidentiality as "preserving authorized restrictions on information access and disclosure". It concerns who may access or receive information.

5. 5When comparing cloud network access approaches using total cost of ownership (TCO), what should be included?

   1. A.Only the initial equipment purchase price
   2. B.Only recurring cloud infrastructure charges
   3. C.Only one-time migration expenses
   4. D.Both infrastructure costs and operational overheadCorrect answer: D

   Explanation: AWS describes TCO as including "fixed and variable infrastructure costs, operational overhead" along with other cost components. A TCO comparison extends beyond the initial purchase.

6. 6A company uses a cloud environment exclusively for its own departments, operated by a third party off premises. Which deployment model fits this description?

   1. A.Public cloud
   2. B.Private cloudCorrect answer: B
   3. C.Community cloud
   4. D.Hybrid cloud

   Explanation: NIST states "The cloud infrastructure is provisioned for exclusive use by a single organization". Exclusive use by a single organization identifies the private model; third-party operation and off-premises hosting are compatible with it.

   Reference: The NIST Definition of Cloud Computing — Section 2, Deployment Models, Private cloud

7. 7What is a network switch's primary role within a local cloud LAN?

   1. A.Forwarding data between separate IP networks
   2. B.Forwarding data between devices on the same networkCorrect answer: B
   3. C.Filtering all traffic based on application security rules
   4. D.Creating an encrypted tunnel across the internet

   Explanation: Cloudflare states that "A network switch forwards data packets between groups of devices in the same network". Routing between networks, firewall filtering and encrypted tunnels have different primary functions.

8. 8When a browser receives an HTTP 404 response, what does it normally indicate?

   1. A.The requested resource was permanently moved.
   2. B.The server cannot find the requested resource.Correct answer: B
   3. C.The request completed successfully.
   4. D.The server has accepted a new resource for creation.

   Explanation: MDN states for HTTP 404: "The server cannot find the requested resource." Servers may sometimes use 404 to conceal a resource, so the response alone does not prove permanent deletion.

   Reference: How the web works — Other status codes, 404

9. 9Which information-security objective addresses unauthorized modification of stored cloud records?

   1. A.Service availability
   2. B.Source authenticity
   3. C.Data confidentiality
   4. D.Data integrityCorrect answer: D

   Explanation: NIST defines integrity as "guarding against improper information modification or destruction". Unauthorized changes to records violate that property.

   Reference: Data Integrity: Detecting and Responding to Ransomware and Other Destructive Events — Executive Summary, CIA triad

10. 10A migration plan requires temporary network connections and services to transfer data. How should these costs be treated in a business case?

    1. A.Include them as migration infrastructure costs.Correct answer: A
    2. B.Exclude them because they occur before the cloud system is fully operational.
    3. C.Count them only as the old system's future licensing fees.
    4. D.Assume they are already included in every provider's standard subscription.

    Explanation: AWS includes "network connections, data migration services" among migration infrastructure costs. Temporary migration expenses affect the business case even though they may not recur.
