Physical Server A hosts Hypervisor A which hosts Virtual Server A, Virtual Server B and an active cluster comprised of three virtual servers. Virtual Server A hosts Ready-Made Environment A. Ready-Made Environment A uses Cloud Storage Device A to store data related to the ready-made environment and its users. Cloud Service A is hosted by a high-availability (HA) virtual server cluster. Hypervisor A is a cluster-enabled hypervisor.
Developers access Ready-Made Environment A to work on the development of a new solution (1).
During this usage. Ready-Made Environment A regularly reads and writes data to Cloud Storage Device A (2). Cloud Service Consumer B accesses Cloud Service A (3). Cloud Service A queries data residing in Cloud Storage Device A in response to processing requests from Cloud Service Consumer B (4).
Hypervisor A is made part of a cluster of hypetvisors. Ready-Made Environment A, which is still hosted by Virtual Server Aon Hypervisor A, subsequently becomes unexpectedly unavailable. It then takes twenty minutes to pass before Virtual Server A and Ready-Made Environment A become available again on Hypervisor B (a hypervisor that is also part of the hypervisor cluster). This delay is considered unacceptable by Cloud Consumer A. Furthermore, after being relocated
to Hypervisor B, Virtual Server A is unable to connect to the network. By the time the cloud provider rectifies this second problem, Cloud Consumer A experiences a total of two hours of downtime.
Which of the following statements describes a solution that can minimize or entirely avoid a delay for the runtime relocation of Ready-Made Environment A?
Virtual Server A is hosted by Hypervisor A, which resides on Physical Server A. Virtual Server A
hosts Cloud Services A and B. Virtual Server B is hosted by Hypervisor B on Physical Server B.
Physical Server C is currently not being used.
Cloud Service Consumer A sends a request to Cloud Service A that is intercepted by Pay-Per-Use
Monitor A
(1), which collects billing-related usage data that is later forwarded to the billing management system
(2). Cloud Service A receives and processes the request
(3). Cloud Consumer B accesses the usage and administration portal
(4) to access data on Cloud Storage Device B. Pay-Per-Use Monitor B intercepts the data access to collect and forward billing-related usage data to the billing management system
(5). Cloud Storage Device B processes the data access request from Cloud Consumer B
(6).
Cloud Service Consumer A and Cloud Consumer B belong to Organization A
Cloud Storage Device B is accessed on a regular basis by Cloud Consumer B. However,
managers at Organization A receive reports from their cloud resource administrator that Cloud Storage Device B is unavailable for longer periods and more frequently than what they expected, based on the SLA availability guarantee they were provided by the cloud provider. This results in wasted time when the cloud resource administrator attempts to upload or access data and then discovers that Cloud Storage Device B is unavailable. The cloud resource administrator requires a means of checking for the availability of Cloud Storage Device B prior to attempting access.
As the workload increases on Physical Server B, Cloud Consumer B begins to receive runtime exceptions and degraded data access performance from Cloud Storage Device B. It is determined that the cause of the deteriorating performance is a network bottleneck that has formed on Physical Server B due to its bandwidth capacity being reached, primarily because of other cloud consumer organizations also sharing its hosted IT resources.
Organization A receives a monthly billing statement that shows the charges for the total usage of Cloud Service A during that period. However, Organization A requires a more detailed breakdown of the types of usage and their associated costs. For example, Cloud Service Consumer A can issue requests for information by employees within Organization A and on behalf of clients of Organization A. Organization A requires a breakdown of the usage costs incurred on behalf of clients so that it can bill the clients for this usage accordingly. The cloud provider informs Organization A that it has no existing monitor that can collect and log this detailed usage information and suggests that Organization A customize its own monitor.
Which of the following statements lists the patterns that can be applied to solve these three problems?
A cloud provider has two cloud environments (Cloud A and Cloud B) that are in different geographical regions. Cloud Service A resides in Cloud A. A redundant implementation of Cloud Service A resides in Cloud B. An automated scaling listener is used in Cloud A to automatically balance the workload of requests for Cloud Service A across the two redundant implementations.
Cloud Service A is required to access Cloud Storage Device A, which also resides in Cloud A. A redundant implementation of Cloud Storage Device A is located in Cloud B. A failover system is used to ensure that if the Cloud Storage Device A implementation in Cloud A fails, the Cloud Storage Device A implementation in Cloud B takes its place.
Cloud Service Consumer A is owned by Organization A. Cloud Service Consumer A sends a request to Cloud Service A (1). The automated scaling listener intercepts the request and directs it to the Cloud Service A implementation in Cloud A (2). This Cloud Service A implementation attempts to access Cloud Storage Device A in Cloud A, but Cloud Storage Device A fails (3). The failover system redirects the request to Cloud Storage Device A in Cloud B (4). Cloud Service Consumer B sends a request to Cloud Service A (5). The automated scaling listener intercepts the request and directs it to the Cloud Service A implementation in Cloud B (6). This Cloud Service A implementation accesses Cloud Storage Device A in Cloud B to fulfil the request (7).
An unexpected outage occurs in Cloud A, making Cloud Service A unavailable. Organization A notices that its cloud resource administrator can continue accessing data in Cloud Storage Device A via a usage and administration portal. Cloud Service Consumer A is unable to access data in Cloud Storage Device A via Cloud Service A during the outage. The cloud resource administrator manually restarts Cloud Service A and it continues to function normally.
Organization A needs to change the cloud architecture so that when Cloud Service A fails, three automated attempts are made to recover it before a manual restart is required.
Due to data storage regulations, Organization A is prohibited from storing some types of data across more than one cloud storage device. A large amount of the data in Cloud Storage Device A is subject to these regulations. Because of an increase in usage, the capacity of Cloud Storage Device A has reached its limit, resulting in regular delays and lag time when processing data access requests during peak usage times.
A management change by another cloud consumer organization inadvertently reconfigures settings in the failover system used in Cloud A for Cloud Storage Device A. Organization A complains to the cloud provider who promises to take the steps required to prevent management tasks performed by other cloud consumer organizations from affecting IT resources being used by Organization A.
Which of the following statements describes a solution that can resolve all of these issues?
Cloud Service A is hosted by Virtual Server A, which is hosted by Hypervisor A on Physical Server A. Virtual Server B is hosted by Hypervisor B on Physical Server B.
Cloud Service Consumer A accesses Cloud Service A and the request is intercepted by an SLA monitor (1). Cloud Service A receives the request (2) and accesses Cloud Storage Device A and Cloud Storage Device B (3).
Cloud Service Consumer A belongs to Organization A, which is leasing all of the IT resources shown in the figure as part of an laaS environment.
Cloud Storage Device B has a higher performance capacity than Cloud Storage Device A. Cloud Storage Device C has a higher performance capacity than Cloud Storage Device B. The requests being received by Cloud Service A from Cloud Service Consumer A have recently increased in both quantity and in the amount of data being queried, written and read from Cloud Storage Device A. As a result, Cloud Storage Device A's capacity is frequently reached and it has become unstable at times, timing out with some requests and rejecting other requests.
Cloud Storage Device C is used by Organization A to store backup data on a daily basis. One day, a hardware failure within Cloud Storage Device C results in the permanent loss of data.
Organization A requires a system that will prevent this type of failure from resulting in data loss.
The cloud provider is planning to implement a routine maintenance schedule for Cloud Storage Devices A, B, and C and issues a notice stating that the new schedule will start next week. An outage of 30 minutes every Thursday and Sunday at 8:00 PM is needed for the maintenance tasks. Upon hearing this, Organization A complains that they cannot afford to have Cloud Storage Devices A and B become inoperable, especially not during the weekdays.
Which of the following statements describes a solution that can address Organization A's issues?
Cloud Service A accesses LUN Aon Cloud Storage Device A when it receives requests to process data from cloud consumers. Cloud Service A is hosted by Virtual Server A. The usage and administration portal can be used to access and manage the data in Cloud Storage Device B, which is also hosted by Virtual Server A. Virtual Server A is further hosted by Hypervisor A, which resides on Physical Server A. Virtual Server B is part of a virtual server cluster hosted by Hypervisor B. which resides on Physical Server B. Physical Server C is not in use and does not yet have an operating system installed.
Cloud Service Consumer A sends a request to Cloud Service A (1), which accesses data in LUN Aon Cloud Storage Device A (2). Cloud Consumer B uses the usage and administration portal to upload new data (3). The data is placed in LUN B on Cloud Storage Device B (4).
Cloud Service Consumer A and Cloud Consumer B belong to Organization A, which is leasing Virtual Server A and Virtual Server B from the cloud provider. Organization A also proceeds to lease Physical Server C as part of a new laaS agreement it signs with the cloud provider.
Organization A wants to provision Physical Server C with a number of legacy systems that cannot be deployed on virtual servers. However, when it attempts to do so, it realizes that its laaS package only provides Physical Server C as an out-of-the-box hardware server without anything installed on it. In order to deploy its legacy systems Organization A requires that Physical Server C first has an operating system installed, but it has no means of remotely provisioning Physical Server C with an operating system.
Organization A would like to deploy two of its legacy systems on Virtual Server A and to further extend Cloud Service A's functions so that it can be used as an external interface for cloud service consumers to access legacy system features. Additionally, Organization A would like to deploy three of its mission-critical legacy systems on Virtual Server B in order to take advantage of the additional performance and failover benefits provided by the virtual server cluster that Virtual Server B is part of. Each of the five legacy systems is comprised of dozens of components that need to be installed individually. Instead of manually installing each component of each legacy system, Organization A would like to customize workflows that can automate these deployment tasks.
During the first few months of working with its cloud-based legacy systems. Organization A receives a number of complaints from users that the cloud-based legacy systems are at times behaving erratically. However, when cloud resource administrators with Organization A review the cloud provider's reports that log usage, downtime and other runtime characteristics, they do not find any indication of erratic behavior or any other comparable problems. After some further investigation, the cloud resource administrators determine that the nature of the erratic behavior is specific to proprietary features of the legacy systems and is therefore not monitored or logged by the cloud provider's standard audit monitor, pay-per-use monitor or automated scaling listener.
The cloud resource administrators recommend that a new service agent be developed with features customized to monitor the legacy systems.
Which of the following statements provides a solution that can address Organization A's requirements?
