Advanced Cloud Architecture and Cloud Architecture Lab account for approximately 50-60% of the exam. These domains test your ability to design complex systems and troubleshoot real-world scenarios. Prioritize these areas during your final review to maximize your score.
In practice, you begin with Fundamental Cloud Computing and Cloud Technology Concepts to understand available tools and services. Fundamental Cloud Architecture teaches you to design basic solutions. Advanced Cloud Architecture extends this to handle scale, resilience, and cost optimization. Cloud Architecture Lab ties everything together through hands-on configuration and validation. This progression mirrors how architects grow from learning theory to solving complex problems.
Direct experience with at least one major cloud platform (AWS, Azure, or GCP) is valuable but not required. Focus on understanding architectural principles and practicing configuration tasks in the lab simulations. If you have limited hands-on time, prioritize labs covering networking, security, and auto-scaling, as these appear frequently in scenario questions.
Many candidates rush through scenario questions without carefully reading all requirements, leading to suboptimal choices. Others confuse similar technologies (for example, different storage types or load-balancing strategies) and select the wrong tool for the job. A third common error is underestimating the importance of cost optimization and compliance in architectural decisions. Read each question twice, consider all constraints, and justify your answer choice before moving on.
In your final week, avoid learning new topics; instead, focus on weak areas identified in practice tests. Review explanations for questions you answered incorrectly or guessed on. Complete one full-length timed practice test three to five days before the exam, then spend the last few days reviewing high-weight domains (Advanced Cloud Architecture and Cloud Architecture Lab) and doing quick definition reviews. Get adequate sleep the night before the exam to ensure sharp focus.
Cloud Storage Device A contains LUN A and can be accessed by external cloud consumers via a proprietary user portal that is used primarily by cloud consumers to upload and manage data for backup purposes. Pay-Per-Use Monitor A tracks the amount of data being uploaded and forwards this information to a billing management system. Cloud Storage Device B is a secondary cloud storage device. Data from Cloud Storage Device A is replicated synchronously to Cloud Storage Device B using a storage replication program (not shown). Cloud Storage Device A is further administered by a cloud resource administrator that works for the cloud provider, who accesses the cloud storage device via an internal usage and administration portal.
Three different cloud consumers (Sarah. William, Matilda) access Cloud Storage Device A to upload data for backup purposes (1). These three cloud consumers belong to different departments within the same organization, and therefore all three share LUN A. Pay-Per-Use
Monitor A collects the storage space data and forwards it to the billing management system (2).
The cloud provider offers premium and discount storage plans. With the premium plan, the data stored on Cloud Storage Device A is also replicated to Cloud Storage Device B. With the discount plan, the data stored on Cloud Storage Device A is not replicated. Both plans are based on fixed disk storage allocation. The cost of the premium plan is $5 per week for every GB of storage space and the cost of the discount plan is $2 per week for every GB of storage space. The SLA from the cloud provider guarantees availability of 97% for access to Cloud Storage Device A.
The three cloud consumers use Cloud Storage Device A as follows:
Sara signs up for the discount backup plan and is allocated 50 GBs of storage space. A week later, she uploads 10 GBs of backup data. A week after that, she uploads another 35 GBs. She later finds out that for those two weeks her organization was billed $200, which is more than she was expecting. After she complains to the cloud provider, she learns about how fixed-disk storage allocation is billed. She asks the cloud provider to change her account to a different storage plan where she is only billed for the actual amount of storage space she uses at any given time. The cloud provider assures her that a new system will be set up to accommodate this request.
William is on the premium backup plan. He uploads 1 to 3 GBs of important business data every day. After two weeks of daily uploads, he realizes that the centralized nature of the backup data on the cloud makes it more convenient for reporting purposes than the distributed nature of the same data in his on-premise environment. He uses an analysis tool to run queries against the cloud-based data. However, due to the large quantity of redundant data, the queries end up being ineffective and take too long to run. He asks the cloud provider to find a solution that can streamline the cloud-based data by reducing redundancy. By reducing the overall quantity of the data, the analysis queries will run faster.
Matilda is on the discount backup plan and uploads backup data on a daily basis. Over the course of two weeks she uploads over 200 GBs of data. She performs a daily backup at the end of each day by identifying the data to back up and then using the proprietary user portal to run the cloud backup procedure. This procedure can take 5 to 45 minutes, depending on the amount of data she is uploading. Matilda performs this as her last task of the day and therefore initiates the procedure before she leaves, but does not wait for it to complete. One day, she receives an e-mail from the cloud provider explaining that the backup procedure from the previous day had failed due to an unexpected hardware failure that occurred on Cloud Storage Device A. The notification e-mail goes on to state that this type of failure falls within the 97% availability guarantee of her organization's SLA, and is therefore in compliance with the current provisioning agreement. Had a disaster occurred that night, the on-premise data could have been lost and Matilda would be held accountable. Matilda contacts the cloud provider to demand that the provisioning agreement be amended to upgrade their existing SLA to the maximum possible availability (which, for this cloud provider, is 99.999%). The cloud provider agrees to establish a system to accommodate this request.
Which of the following statements lists the patterns that can be applied to address the three issues raised by the three cloud consumers?
Virtual Server A and Virtual Server B are hosted by Hypervisor A, which resides on Physical Server A. Virtual Server A hosts Cloud Service A. Virtual Server C. Virtual Server D, Virtual Server E and Virtual Server F are hosted by Hypervisor B on Physical Server B. Physical Server C, which hosts Hypervisor C, is currently not being used.
Cloud Service Consumer A accesses Cloud Service A (1), which accesses files stored in a folder on Virtual Server A (2). Cloud Consumer B uses Proprietary User Portal A to administer legacy software (not shown) installed on Virtual Server D (3). Proprietary User Portal B and Proprietary User Portal C are also available for accessing additional legacy systems located on Virtual Server F; however, they are not often used.
The cloud shown in the figure is a private cloud. Department A and Department B share IT resources within the private cloud and are part of the same organization. Cloud Service Consumer A belongs to Department A and Cloud Consumer B belongs to Department B.
During routine access of Cloud Service A by Cloud Service Consumer A, the Department A cloud resource administrator is notified that a hardware fault is occurring within Physical Server A that will soon cause it to fail. The cloud resource administrator scrambles to arrange for Cloud Service A to be relocated but is unable to do so before Physical Server A does fail. It takes several more hours of downtime until, with the cooperation of the cloud provider, the Cloud Service A implementation is successfully moved to Physical Server C and made live again. Managers at Department A demand that a system be put in place to avoid this scenario in the future.
Cloud Service A was initially developed specifically for Department A's Cloud Service Consumer A. However, recently Department B has indicated that it will be developing its own cloud service consumer that will also need to regularly access Cloud Service A. After this new cloud service consumer is deployed, both Department A and Department B experience occasional runtime errors when their cloud service consumers attempt to access Cloud Service A at the same time.
Cloud Service A accesses a legacy system on Virtual Server A that requires regular updates and patches to stay current. Each time the legacy system is updated, Cloud Service A needs to undergo an update as well, during which it needs to be temporarily unavailable. Department A managers ask the cloud provider to extend the cloud architecture so that a duplicate, secondary implementation of Cloud Service A can be made available while the primary implementation undergoes a maintenance update.
Which of the following statements provide a solution that can adequately resolve all of Departments A and B's issues?
Cloud Service A and Cloud Service B perform different functions but both share access to Cloud Storage Device A when fulfilling requests from cloud service consumers that require data access.
Cloud Services A and B are hosted by Virtual Server A, which is hosted by Hypervisor A on Physical Server A.
Cloud Service Consumer A accesses Cloud Service A to issue a request for data (1). Cloud Service A queries a database in Cloud Storage Device A to retrieve the data (2). Upon receiving the requested data, Cloud Service Consumer A combines it with additional data to form a new collection of data. Cloud Service Consumer A then accesses Cloud Service B and provides it with the new data (3). Cloud Service B accesses a different database in Cloud Storage Device A to store the new data (4). Cloud Consumer B accesses the usage and administration portal to upload new data (5). The data is uploaded to Cloud Storage Device B (6).
Cloud Service Consumer A belongs to Organization A. Cloud Consumer B belongs to Organization B.
Cloud Service A is a SaaS product offered by the cloud provider to the general public, and is therefore used by numerous cloud consumers from different organizations at different times. Cloud Service B is also a SaaS product as part of the same overall solution as Cloud Service A.
However, because a given cloud service consumer only needs to access Cloud Service B when the data it receives from Cloud Service A meets certain criteria, it is not used nearly as much as Cloud Service A. Cloud Service A currently has a hard threshold allowing no more than 10 concurrent instances of it to exist at once. One day, Cloud Service Consumer A attempts to access Cloud Service A as the eleventh cloud service consumer, and is predictably rejected.
Cloud Service Consumer A belongs to Organization A, one of the cloud provider's most important customers. Therefore, when Organization A complains about not being able to access Cloud Service A during peak usage times, the cloud provider agrees to provide a solution.
As a result of a natural disaster, the cloud provider's data center that houses Physical Server A becomes unexpectedly unavailable. Physical Server A subsequently becomes unavailable for nearly two days. This outage exceeds what the cloud provider guaranteed in its original SLA and the cloud provider agrees to not charge Organization for usage fees for an entire month as compensation. However, the unavailability of Physical Server A had a significant impact on Organization As business, resulting in financial loss and loss of confidence of its clients.
Organization A informs the cloud provider that it cannot continue working with this cloud unless the cloud provider can guarantee that the availability of Physical Server A will no longer be dependent on a single data center or a single geographic region.
Organization B receives its latest monthly invoice from the cloud provider and discovers that the charges are identical to the invoice it received last month, even though the usage and administration portal shows that its data usage is a third less. They bring this issue to the attention of the cloud provider and are informed that they are currently subscribed to a fixed-allocation plan.
The cloud provider explains that in order to get them on a plan whereby they are charged only for actual data usage, Cloud Storage Device B would need to be upgraded and a system capable of tracking runtime usage would need to be established. Organization B asks the cloud provider to make these changes.
Which of the following statements provides a solution that can address Organization A's and Organization B'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?
Ready-Made Environment A is hosted by Virtual Server A and Ready-Made Environments is hosted by Virtual Server B. Virtual Servers A and B are hosted by Hypervisor A, which is part of a hypervisor cluster. An automated scaling listener intercepts cloud consumer requests and automatically invokes the on-demand generation of additional instances of ready-made environments, as required.
A self-service portal and a usage and administration portal are also available to cloud consumers.
The self-service portal can be used to request the provisioning of a new ready-made environment.
Any cloud consumer that has already had a ready-made environment provisioned can configure and view information about that ready-made environment via the usage and administration portal.
Cloud Consumer A accesses Ready-Made Environment A to work on the development of a new cloud service (1). Cloud Consumer B accesses Ready-Made Environment B to test a recently completed application comprised of three cloud services (2). Cloud Consumer C accesses the self-service portal to request the creation of a new ready-made environment (3).
The cloud provider is required to perform an emergency maintenance outage on a cloud storage device used by all ready-made environments. The unplanned outage takes two hours. During this period, Cloud Consumers A and B are unable to access Ready-Made Environments A and B and Cloud Consumer C receives an error when submitting a request to create a new ready-made environment.
After the maintenance outage is over, Cloud Consumers A and B encounter the following problems:
Cloud Consumer A is unable to recover session data that was kept in memory for an extended period, prior to the time of the outage.
Cloud Consumer B has no access to Virtual Server B, which was moved to Hypervisor B during the maintenance outage. When Cloud Consumer B attempts to ping Virtual Server B, the request times out.
Even though Cloud Consumer C is able to log into the usage and administration portal to confirm that its ready-made environment was successfully provisioned, the unexpected outage has raised concerns about the stability of the ready-made environment's underlying infrastructure. Cloud Consumer C informs the cloud provider that it cannot proceed with its lease of the ready-made environment if there are future occurrences of this type of maintenance outage.
Which of the following statements can help address the problems and concerns of the three cloud consumers?
