最新的 Certified Cloud Computing Specialist C90-03A 免費考試真題:

1. Cloud X (owned by Cloud Provider X) provides Physical Server A which hosts Virtual Servers A and B. Virtual Server B hosts Ready-Made Environments A and B. Cloud Service Consumer A uses Virtual Server A as part of an IaaS leasing agreement in which Cloud Consumer A is charged a fixed monthly fee for unlimited access. Cloud Service Consumers B and C use Ready-Made Environments A and B respectively as part of a PaaS leasing agreement based on per-minute usage fees. In both cases, access is monitored via Pay-For-Use Monitor A, which keeps track of log-in and log-out times in order to calculate the usage charges that are billed to Cloud Consumers B and C.

Physical Server A begins to become unstable. Over the course of a 24 hour period, the server shuts down three times, taking down Virtual Servers A and B with it. This causes numerous problems for Cloud Service Consumers A, B and C, which lose connections and encounter a variety of exceptions.
A subsequent investigation of the log files generated by Pay-For-Use Monitor A reveals that the three server crashes coincided with the usage periods of Ready-Made Er n'ronment B b> Cloud Service Consumer B. De 'elopers at the Cloud Consumer 3 organization confirm they did not actually log in during those periods, which leads Cloud Provider X to discover that another cloud service consumer has been posing as Cloud Service Consumer B in order to maliciously access Ready-Made Environment B, Virtual Server B, and Physical Server B on Cloud X. The investigation concludes that the malicious cloud service consumer was able to carry out the attack successfully by obtaining a weak password being used by developers from Cloud Consumer B.
Which of the following statements accurately identifies the type of security threat that corresponds to the described attack - and -provides a solution that can directly mitigate this type of security threat within Cloud X?

A) Ready-Made Environments, Virtual Server B and Physical Server B were subjected to an attack that succeeded due to overlapping trust boundaries. This type of attack can be mitigated by implementing the single sign-on mechanism.
B) Ready-Made Environment B. Virtual Server B and Physical Server B were subjected to a weak authentication attack that can be mitigated by implementing the encryption and digital signature mechanisms.
C) Ready-Made Environment Virtual Server B and Physical Server B were subjected to a malicious intermediary attack that can be mitigated by implementing the cloud-based security groups and hardened virtual server images mechanisms.
D) Ready-Made Environment B, Virtual Server B and Physical Server B were subjected to a virtualization attack that can be mitigated by implementing the encryption and digital signature mechanisms.

2. Organization A has been expanding and, as a result, is outgrowing the processing capacity of its on-premise Service A implementation. It is determined that this is due to usage thresholds of Service A and complex data processing limitations in Database A. The diagram depicts Organization A's current on-premise environment, where Service Consumers A. B and C attempt to access Service A at the same time. Service Consumer A successfully accesses Service A, which then successfully retrieves the requested data (1). Service Consumer B successfully accesses Service A, but due to the complex data structure, the request for the data times out and fails (2). Finally, Service Consumer C attempts to access Service A, but is rejected because Service A is unable to accept more concurrent requests.

Organization A is required to continue using its on-premise Service A implementation, with the exception of Database A, which does not need to remain on-premise. Database A is dedicated to Service A and is comprised of relational data.
Which of the following statements provides a solution that uses cloud-based IT resources to solve the performance limitations of Service A and Database A?

A) None of the above.
B) A cloud balancing solution can be implemented within the public cloud, whereby a redundant Cloud Service A implementation is established. Cloud Service A becomes the first point of contact for Service Consumers A, B and C (thereby turning them into Cloud Service ConsumersA. B and C). Upon reaching its usage threshold (which will be higher than the on-premise Service A), Cloud Service A automatically routes usage requests to Service A. The resource replication mechanism is implemented within the cloud to establish a replicated Database A that can further be used to load balance data access requests from Cloud Service A or Service A.
C) Automated scaling listener mechanisms can be implemented in both the on-premise and cloud environments. Using built-in resiliency features, these service agents can be configured to coordinate the routing of messages between the on-premise Service A implementation and a redundant Cloud Service A implementation. This dynamic functionality can avoid service usage thresholds in both Service A and Cloud Service A.
D) The virtual server and resource replication mechanisms can be implemented to replicate Service A and Database A across both on-premise and cloud environments. This enables on-demand usage in that requests sent by Service Consumers A, B and C will automatically be redirected to the replicated service and/or database. As a result, Service A' s usage thresholds will no longer result in rejected requests and Database A' s processing limitations will no longer result in failed data access attempts.
