SOA Certified Professional Cloud Technology Lab Sample Questions:

1. A cloud consumer is interested in leasing cloud-based virtual servers. It compares the virtual servers offered by Cloud Provider X and Cloud Provider Y.
Cloud X (owned by Cloud Provider X) and Cloud Y (owned by Cloud Provider Y) both provide shared physical servers that host multiple virtual servers for other cloud consumers.
The virtual servers on Cloud X are accessed directly, whereas the virtual servers on Cloud Y are accessed via an automated scaling listener. On Cloud X, virtual servers are pre-configured to support a specific amount of concurrent cloud service consumers. When this threshold is exceeded, cloud service consumer requests are rejected. Due to the use of the automated scaling
listener, virtual servers on Cloud Y can provide a greater level of elasticity.

The hourly cost to the cloud consumer to use a virtual server on Cloud X is half that of the cost to use a virtual server on Cloud Y.
Within a one month period, Cloud Provider X bases its hourly charge on the maximum number of virtual servers used. Within a one month period, Cloud Provider Y bases its hourly charges on actual virtual server usage. Cloud Provider Y charges $20 for each hour that a cloud consumer uses a virtual server.
The cloud consumer predicts its monthly usage requirements to be as follows: The cloud consumer is required to choose the cloud provider with the lowest on-going cost, based on its predicted usage. Which of the following statements accurately calculates the on-going usage costs of Cloud Providers X and Y and correctly states the cloud provider that the cloud consumer must choose?

A) The total usage duration is (3 x 20) + (4 x 30) + (5 x 50) hours = 430 hours.
The actual usage is (20 + 30 + 50) hours = 100 hours.
The cost of using virtual servers from Cloud Provider X is (430 X $10) = $4,300.
The cost of using virtual servers from Cloud Provider Y is (100 X $20) = $2,000.
The cloud consumer must therefore choose Cloud Provider Y.
B) The total usage duration is (20 + 30 + 50) hours = 100 hours.
The actual usage is (20X3)+ (30X4) + (50X5) hours =430 hours.
The cost of using virtual servers from Cloud Provider Xis100X5X$10 = $5,000.
The cost of using virtual servers from Cloud Provider Y is 430 X $20 = $8,600.
The cloud consumer must therefore choose Cloud Provider X.
C) The total usage duration is (20 + 30 + 50) x 12 hours = 1,200 hours.
The actual usage is (20 X 3) + (30 X4) + (50 X 5) server hours = 430 server hours.
The cost of using virtual servers from Cloud ProviderXis12X5X$10 = $600.
The cost of using virtual servers from Cloud Provider Y is 430 X $20 = $8,600.
The cloud consumer must therefore choose Cloud Provider X.
D) The total usage duration is (20 + 30 + 50) hours = 100 hours.
The actual usage is (20 + 30 + 50) X 5 server hours = 500 server hours.
The cost of using virtual servers from Cloud Provider X is (500 X 5 X$10) = $25,000.
The cost of using virtual servers from Cloud Provider Y is (500 X $20) = $10,600.
The cloud consumer must therefore choose Cloud Provider Y.

2. Cloud Provider Y owns Cloud Y, which provides a set of cloud services, virtual servers and one physical server. Cloud Services A and B are hosted on Virtual Server A, which is hosted by Physical Server A. Physical Server A also hosts Virtual Server B, which hosts redundant implementations of Cloud Services A and B for load balancing purposes. Cloud Service Consumer A is accessing Cloud Service A located on Virtual Server A. Cloud Service Consumer B is accessing Cloud Service B located on Virtual Server B. Cloud Service Consumers A and B are both owned by Cloud Consumer X.
Cloud Consumer X has recently complained that Cloud Services A and B have become less available than what is guaranteed in their service level agreements (SLAs). Cloud Provider Y launches an investigation that reveals that Virtual Servers A and B have been subjected to denial of service attacks. This is confirmed as the cause of the decline in the availability of Cloud Services A and B.

Which of the following statements describes a solution that can increase the availability of Cloud Services A and B?

A) Cloud Provider Y can move Cloud Service B to Virtual Server A, thereby positioning Virtual Server B as a redundant fallback server used when Virtual Server A is successfully attacked. Similarly, Cloud Provider Yean move Cloud Service A to Virtual Server B, so that Virtual Server A acts as a redundant fallback server for when Virtual Server B is successfully attacked.
B) Cloud Provider Y can implement a cloud bursting system, whereby Cloud Service A on Virtual Server B automatically takes the place of Cloud Service A on Virtual Server A when that service fails. Similarly,Cloud Service B on Virtual Server A can then automatically take the place of Cloud Service B on Virtual Server A when that service fails.
C) Cloud Provider Y can implement the identity and access management mechanism to mitigate denial of service attacks and can further implement the failover system mechanism (by introducing a redundant physical server with redundant virtual servers) so that when an attack is successful on a given virtual server, a redundant virtual server can take its place.
D) Cloud Provider Y can introduce a single sign-on mechanism for Virtual Server A to mitigate denial of service threats. The automated scaling listener can then be implemented on VirtualServer B in order to limit the number of instances of Cloud Services A and B. This will prevent Virtual Server B from overloading due to denial of service attacks.

3. 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 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.
B) 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.
C) 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.
D) 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.
