In informative level, we should be more efficient. In order to take the initiative, we need to have a strong ability to support the job search. And how to get the test EMC certification in a short time, which determines enough qualification certificates to test our learning ability and application level. This may be a contradiction of the problem, we hope to be able to spend less time and energy to take into account the test EMC certification, but the qualification examination of the learning process is very wasted energy, so how to achieve the balance? The E20-918 exam prep: IT-as-a-Service Expert Exam for Cloud Architects can be done.

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.
Which solution would you recommend to best support the web service high availability and minimize service network latency for the consumer?

A) Implement a global load balancing service as a front-end for the web services.
B) Use a content delivery network to distribute static web content.
C) Implement a Layer 7 firewall within the public cloud to filter out unnecessary traffic.
D) Implement a QoS policy that provides a higher priority to http traffic.

3. You are a Cloud Architect working with a large financial services company. They currently have a large, hybrid cloud that includes multiple CSPs. The company recently suffered a breach on some of their web servers hosted at one of the CSPs and were not alerted to it.
Which product would you recommend to help the company improve their response to threats such as this, and why?

B) VMware vCenter Operations, for its real-time monitoring of log and event data

4. Refer to Scenario 4.

A construction firm with a substantially virtualized IT infrastructure wishes to consider cloud enablement next, as part of its logical progression to ITaaS.
As a first step, the firm plans to transition one relatively low-risk service -- daily backup -- to a public CSP. The existing backup strategy involves array-based cloning, followed by backup of the clones with dedicated servers. The system is functional; however, since the backup target device is due for a technology refresh, the firm is open to alternatives.
In evaluating alternatives, the key consideration is the ability to meet backup windows for daily incremental backups during the work week.
As advisor to this firm, you have conducted a quick assessment of the candidate applications and storage involved in daily backups. Relevant details are presented in the exhibit.
Your first goal in this proof-of-concept is to demonstrate one quick and successful backup run to the CSP for two different customer applications.
Which two applications would you select, if your desired outcome is backup completion within the shortest possible time?

A) HR and CRM
B) CRM and SCM
C) Messaging and SCM
D) Messaging and CRM

5. A small company has been using a public cloud IaaS provider for several months. During this time the company has seen significant growth in revenue. This growth has triggered a surge in hiring, which has forced the company to repeatedly purchase additional services at premium cost from their CSP.
The company has leased a data center and started designing a cloud infrastructure to deploy a private cloud environment. The underlying hypervisor technology they chose is different than that of the CSP. Once the initial infrastructure has been implemented, they will transition to a hybrid cloud model. New services will only be deployed in the private cloud.
A new CIO has just been hired, but has little experience with cloud computing. You are a Cloud Architect who has been asked to consult on several areas of concern.
The first service must be deployed in the private cloud within the next month. The CIO does not want to rely solely on the existing single sign-on solution hosted in the public cloud, because network disruption between the clouds would impact user access.
What is the best option for an interim single sign-on solution that can be replaced once the private cloud is fully implemented?

A) Public Key Infrastructure
B) OAuth
C) SAML
D) Identity Provider
