Preguntas del test (10)

  1. 1The SaaS (Software-as-a-Service) delivery model generally represents __________________.
    1. AA service consumer which access to the cloud service contract, but not to any
      underlying IT resources or implementation details.
    2. BA consumer which is granted limited usage control over the cloud service, but the
      cloud provider retains administrative control over the cloud service’s underlying
      implementation and IT resources.
    3. CA SaaS product like the SalesForce Sales Cloud (www.salesforce.com/crm/salesforce-automation).
    4. DA service or service-based product that is made available as a shared cloud
      service offered by a cloud provider to cloud consumers.
  2. 2The PaaS (Platform as a Service) delivery model relies on the usage of __________________
    1. AA ready-made environment that establishes a set of pre-packaged products and
      tools used to support the entire delivery lifecycle of custom applications.
    2. BA ready-made cloud that establishes a set of pre-packaged products and tools used
      to support the entire delivery lifecycle of custom applications.
    3. CA ready-made packaged that establishes a set of and tools used to support the entire
      delivery lifecycle of custom applications.
    4. DNone of the above
  3. 3The PaaS delivery model provides a __________________
    1. APre-defined cloud environment with already deployed and congured IT resourcessuitable for scalability and economic purposes.
    2. BPre-defined cloud environment with already deployed and congured IT resources suitable for entirely substitute an on-premise environment.
    3. CPre-defined cloud environment with already deployed and congured
      IT resources suitable for the development and deployment of applications.
    4. DPre-dened cloud environment with already deployed and congured IT resources suitable for deploy their own cloud services to other external cloud consumers.
  4. 4The IT resources provided by laaS (Infrastructure as a Service)
    are generally raw and not precongured,
    therefore
    1. Aused by cloud consumers that require a high level of control over the cloud-based
      environment they intend to create.
    2. BSometimes cloud providers will contract laaS offerings from other cloud providers in
      order to scale their own cloud environments.
    3. Can example of a commercially available laaS product is the Amazon Elastic Compute
      Cloud or EC2 (aws.amazon.com/ec2).
    4. Dplacing the operational responsibility upon the cloud consumer.
  5. 5__________________ provides a self-contained IT environment
    comprised of infrastructure-centric IT resources (including
    hardware, network, connectivity, operating systems, etc.). IT
    resources are typically __________________
    1. AThe SaaS delivery model
    2. Bscaling and packaged into bundles that simplify upfront runtime scaling and
      customization of the infrastructure.
    3. CThe laaS delivery model
    4. Dvirtualized and packaged into bundles that simplify upfront runtime scaling and
      customization of the infrastructure.
  6. 6A cloud deployment model represents a specic type of cloud environment, primarily distinguished by ownership and size;
    public, community, private and hybrid cloud are the four common models. A Private Cloud is:
    1. AA publically accessible cloud environment owned by a third-party cloud provider. IT
      resources on public clouds are generally offered to cloud consumers at a cost
    2. BA cloud environment comprised of two or more different cloud deployment models.
      For example, a cloud consumer may choose to deploy cloud services processing
      sensitive data to a private cloud and non-sensitive cloud services to a public cloud.
    3. CSimilar to a public cloud, except that its access is limited to a specic
      community of
      cloud consumers
    4. DA cloud that is owned by a single organization and that enables the organization
      to use cloud computing technology for internal purposes, as a means of
      centralizing access to IT resources by different parts of the organization.
  7. 7Cloud Bursting is:
    1. AThis is a form of dynamic scaling that combines the automated scaling listener
      and resource replication mechanisms to scale (“or burst”) on-premise IT
      resources into a cloud when pre-dened
      thresholds are reached.
    2. BThis is a form of dynamic routing that combines the automated scaling listener and
      resource replication mechanisms to scale (“or burst”) on-premise IT resources into a
      cloud when pre-dened
      thresholds are reached.
    3. CThis is a form of dynamic routing that combines the automated scaling listener and
      failover system mechanism for load balancing purposes, to increase the performance
      and scalability of IT resources.
    4. DAll of the above
  8. 8Cloud Balancing is:
    1. AThis is a form of dynamic scaling that combines the automated scaling listener and
      failover system mechanism for load balancing purposes, to increase the performance
      and scalability of IT resources.
    2. BThis is a form of dynamic routing that combines the automated scaling listener
      and failover system mechanism for load balancing purposes, to increase the
      performance and scalability of IT resources.
    3. CThis is a form of dynamic scaling that combines the automated scaling listener and
      resource replication mechanisms to scale (“or burst”) on-premise IT resources into a
      cloud when pre-dened
      thresholds are reached.
    4. DAll of the above
  9. 9A replicated IT resource is a virtualized IT resource that shares
    underlying physical resources with other replicated IT
    resources. Select all true statements
    1. AThe most common form of replicated IT resource is the virtual server that is
      replicated from a physical server.
    2. BThe resource replication mechanism can encompass what is often referred to as a
      hypervisor (or virtual machine manager), which enforces multitenancy at a low level
      by isolating virtualized IT resources.
    3. CA replicated IT resource can be considered a virtualized IT resource that shares
      underlying physical resources with other replicated IT resources.
    4. DAll of the above
  10. 10Because cloud consumers can often self-provision cloud-based IT resources, an automated way to monitor usage is required. Select all true statements
    1. AThe pay-for-use monitor is considered a specialized type of cloud monitor
    2. BThe pay-for-use monitor is generally congured to focus on key usage parameters in order to determine that the pay-for-use contractual commitments of the cloud consumer are satised.
    3. CThe pay-for-use monitor isn´t considered a specialized type of cloud monitor.
    4. DAll of the above are true
