A company is deploying a major new business application. The application development has been outsourced to several organizations.
The company has conducted several workshops with all suppliers and the testing team. The outcome of their efforts is a streamlined process that has dramatically reduced the cycle time from development to test, improved communications between all groups, and implemented common standards and objectives.
What have they achieved?

• A. Use of common automation and orchestration processes
• B. Utilization of configuration management methodologies
• C. Transition to a DevOps culture
• D. Implementation of common collaboration tools

Refer to Scenario 7.
"A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%."
During the first day of increased usage, the network link between your data center and the CSP fails due to an external problem. You need to design an alternate solution to prevent degradation in the service offering.
Which solution would provide the best performance for the end user?

• A. Change the configuration of the local load balancer and retain the IP addresses on the servers in the public cloud
• B. Deploy a global load balancer and change the IP addresses for the servers in the public cloud
• C. Change the configuration of the local load balancer and change the IP addresses for the servers in the public cloud
• D. Deploy a global load balancer and retain the IP addresses on the servers in the public cloud

An enterprise's IT department is transitioning to ITaaS. The IT department is developing a service management methodology. They are uncertain about how much of the measurement data should be stored, and for how long. One consideration is the trade-off between storage cost and data granularity.
What would you, the cloud architect, recommend as a best practice?

• A. Keep only peaks and averages for a longer period of time. This minimizes query time, protection, and recovery issues.
• B. Store as much monitoring data as possible given cost constraints. This enables future diagnosis and offers visibility into SLA compliance.
• C. Keep more granular data than just peaks and averages. This allows a higher level of monitoring at reasonable cost, given deduplication and compression.
• D. Keep all raw data, given that storage costs are relatively low.

An IT security team is concerned about the authentication traffic patterns that may be required to integrate the private and public clouds. As a result, IT has elected to federate their active directory using ADFS from the private cloud to the public cloud.
One of the design decisions is whether to use a Layer 2, 3, or 7 firewall / switch mechanism between the public and private clouds. There are trade-offs with each choice.
Which network layer would best address this situation, and why?

• A. Layer 3, because it allows segment isolation while still providing high performance levels.
• B. Layer 7, because it allows control at the application layer and is policy driven.
• C. Layer 2, because it provides the simplest configuration to manage and it is easy to isolate and troubleshoot problems.
• D. Layer 2, because it provides the best performance and it is easy to isolate problems.

A manufacturing company hired you to help them in their journey to a hybrid cloud. You conduct an assessment and recommend migrating several existing Tier 2 applications to a public cloud provider. You must work within the following constraints:
-Migration can be performed only during weekends -Only limited downtime is acceptable -The configuration of the host and applications cannot be changed -The company needs to keep the costs as low as possible -Although there are no specific performance requirements, they are concerned about the quality
of the user experience
Which solution best addresses these needs?

• A. Layer 3 connection over Internet with QoS
• B. Layer 3 connection over Internet with WAN optimization
• C. Layer 2 extension with VPN connection over Internet with WAN optimization
• D. Layer 2 extension with dedicated link and WAN optimization
