EMC IT-as-a-Service Expert Exam for Cloud Architects 認定 E20-918 試験問題:

1. Refer to the exhibit.

You have been hired to assist with a migration to an ITaaS environment. The company has offices
in Atlanta, Dubai, and London, with 5000, 2000, and 3000 employees, respectively. A data center exists in each location, and most services have been virtualized. Messaging services are provided locally to the user.
You have just performed an assessment of the environment. The results are shown in the exhibit.
The CIO is interested in closing one of the data centers and migrating some or all of the services to a public cloud service provider (CSP). Any services that do not get migrated to the CSP will be hosted at one of the other two data centers. Network latency averages 8 milliseconds between the Atlanta and London offices, and 10 milliseconds between the London and Dubai offices. Traffic between Atlanta and Dubai is routed through London.
The eCommerce application is external facing and is hosted at all three data centers. Atlanta services 50% of the users in North and South America. London services 40% of the users in Europe and Asia. Dubai services 10% of the users in Africa and Australia.
You have tentatively chosen a CSP that is housed in Frankfurt, and would have access to 3 Gb/s of network bandwidth to the facility. The CSP's service levels are as follows:
-RPO: 4 hours -RTO: 1 hour -Availability: 99.995%
Your recommendation is to close the Dubai data center over a one-year time horizon.
What migration strategy would you recommend for the services that are currently hosted in the Dubai data center, and why?

A) Messaging to the public cloud; split eCommerce between London and Atlanta; CSP cannot support the availability for eCommerce
B) Messaging and eCommerce to the public cloud; CSP can support availability and bandwidth requirements for both applications
C) eCommerce to the public cloud; Messaging to Atlanta; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from Atlanta
D) eCommerce to the public cloud; Messaging to London; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from London

2. Refer to Scenario 3.
A US company has deployed web services within a private cloud. They wish to provide additional web services elastically and distribute them around the globe using a public cloud provider.
The web services have a dependency on a database resource in the private cloud. The web services are deployed through a service catalog as a standardized service offering, which includes an intrusion prevention system that periodically polls a central management server for security updates. The IPS management server is located within the private cloud.
The web services collect highly regulated personal health information about consumers who are located around the world.
Once the web services were deployed into the public cloud, users started complaining about poor performance. Which solution would most likely improve performance of the web services?

A) Re-architect the web service to be loosely coupled.
B) Allocate additional virtual network interface cards to each web service to increase bandwidth.
C) Implement a global load balancing service as a front-end for the web services.
D) Select a new internet service provider with a better peering relationship for end users.

3. A marketing company is using a Customer Relationship Management SaaS. The SaaS provider has deployed hardware load balancers to distribute users between application servers. User login states are preserved in the load balancer. Subsequent login requests direct each user to the same application server. If the server is unavailable or too busy, the user cannot log on.
Although the company is very happy with the SaaS cost savings they are unhappy with application availability. To improve application scalability the SaaS provider added new servers to the environment. Users, however, are still experiencing the same problem.
Which service characteristic should the SaaS provider implement to improve the user log-on reliability and scale application performance?

A) Abstraction
B) Autonomy
C) Reusable
D) Stateless

4. Refer to the exhibit.

You are discussing a network design that a cloud service provider has proposed for a tenant. The tenant states that one more firewall is required, and you agree.
Where should the firewall be placed?

A) Between the tenant network and the external network
B) Between the Service A and Service B
C) Between VM2 and VM4
D) Between VM2 and the tenant network

5. 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 2, because it provides the simplest configuration to manage and it is easy to isolate and troubleshoot problems.
B) Layer 7, because it allows control at the application layer and is policy driven.
C) Layer 3, because it allows segment isolation while still providing high performance levels.
D) Layer 2, because it provides the best performance and it is easy to isolate problems.
