You plan to use Password Sync on your DirSync Server with Azure Active Directory (Azure
AD) on your company network. You configure the DirSync server and complete an initial synchronization of the users.
Several remote users are unable to log in to Office 365. You discover multiple event log entries for "Event ID 611 Password synchronization failed for domain."
You need to resolve the password synchronization issue.
Which two actions should you perform? Each correct answer presents part of the solution.
- A. Restart Azure AD Sync Service.
- B. Run the Set-FullPasswordSync Power Shell cmdlet.
- C. Force a manual synchronization on the DirSync server.
- D. Add the DirSync service account to the Schema Admins domain group.
Answer : A,B
Explanation:
The Set-FullPasswordSync Power Shell cmdlet resets the password sync state information forcing a full sync the next time the service is restarted. Then we need to restart the service to initiate the sync.
A business has recently implemented a hybrid cloud federated solution, which will allow it to rapidly and dynamically allocate recourses during high demand, and quickly implement its Disaster Recovery Plan (DRP) and Continuity of Operations (COOP). Given this implementations, the IT director is mostly likely concerned about:
- A. maintaining strategic flexibility
- B. reducing OPEX allocations
- C. hiring additional IT staff
- D. eliminations security risks
Answer : D
Explanation:
Initially, the differences between Disaster Recover and Business Continuity should be understood. In comparison they are very similar in that they are (or should be) detailed plans to prepare an organization for events in which a situation presents itself which can cause internal systems failures, or a disruption of business systems in which they are no longer able to function to meet the requirements to perform day to day tasks. These situations almost always result in loss of revenue, and in some cases, loss of client base.
Where these plans differ is in the main concept topic for which they prepare. Business
Continuity Plans generally focus on the continuation of business services in the event of any type of interruptions whether its IT based or other. Disaster Recover Plans often refer to a companys strategy if something happens to crucial business data, and how to restore
/ recover that data (generally in the shortest amount of time possible).

You store data in an Azure blob. Data accumulates at a rate of 0.10 GB per day.
You must use storage analytics data to verify that the service level agreement (SLA) has been met and to analyze the performance of VHDs, including the pattern of usage.
Analytics data must be deleted when it is older than 100 days or when the total amount of data exceeds 10 GB.
You need to configure storage analytics and access the storage analytics data.
Which two approaches will achieve the goal? Each correct answer presents part of the solution.
- A. Disable the data retention policy.
- B. Access analytics data by using the Service Management REST APL
- C. Access analytics data by using the APIs used to read blob and table data.
- D. Configure a data retention policy of 100 days.
Answer : C,D
You have six Ubuntu Linux virtual machines (VMs) that run a Hadoop cluster on Azure. All
VMs were deployed by using Azure Resource Manager (ARM) templates and Azure
PowerShell cmdlets. One of the VMs runs a custom web user interface that allows users to examine the processing jobs within the Hadoop cluster. You are planning a backup strategy for long-term retention and recovery that includes geo-replication.
The backup and recovery solution must be cost effective.
You need to back up all VMs.

Companies that are looking to move from capital expenses to operating expenses benefit from cloud services.
- A. True
- B. False
Answer : A
Explanation:
"Capex vs. Opex" refers to the fact that stocking your own data center requires capital expenditure, while using an external cloud service that offers pay-as-you-go service falls into ongoing operating expenditures: thus the contrast of "Capex vs. Opex."

You have an ASP.NET application that runs in a cloud service. A new version of the application is ready for release. The new version contains code changes and new SSL certificates. The application consists of six instances of a web role and four instances of a worker role.
The application performs at or near full capacity. The cloud service uses the default number of fault domains and upgrade domains.
You plan to deploy the new version of the application. The performance and capacity of the web roles must not degrade during the deployment. Temporary degradation of the worker roles is acceptable. The deployment must take a maximum of six hours.
You need to deploy the new version of the ASP.NET application to the cloud service.
Which two approaches will achieve the goal? Each correct answer presents a complete solution.
- A. Increase the number of web role instances to eight, and then deploy the new version of the application by using an in-place update. Reduce the number of web role instances to six after the upgrade is completed.
- B. Deploy the new version of the application by using an in-place update. Use upgrade domains to ensure that there is sufficient capacity during the upgrade.
- C. Deploy the new version of the application into the staging slot for the cloud service. Then activate the new version of the application by swapping virtual IP (VIP) addresses.
- D. Delete the old version of the application, and deploy the new version of the application.
Answer : B,C
You have a cloud service that runs an external process that is named MyStartupTask.cmd.
The cloud service runs this external process when the web role starts. The external process writes information to the Windows registry. You set the value of an environment variable named MyID to the deployment ID for the current web role instance.
The external process must complete writing the information to the Windows registry before the web role starts to accept web traffic.
You need to configure the cloud service.

Answer :
Which of the following is the primary difference between private and public cloud?
- A. Tenancy of the cloud
- B. Management of the cloud
- C. Service model of the cloud
- D. Locations on the cloud
Answer : D
Explanation:
A private cloud hosting solution, also known as an internal or enterprise cloud, resides on companys intranet or hosted data center where all of your data is protected behind a firewall.
The main differentiator between public and private clouds is that you arent responsible for any of the management of a public cloud hosting solution. Your data is stored in the providers data center and the provider is responsible for the management and maintenance of the data center.

A cloud usage metering scheme allows for which of the following customer chargeback alternatives?
- A. Cost allocation
- B. Cost amortization
- C. Shared cost
- D. Direct cost
Answer : D
Explanation:
CHARGEBACK METHODS -
A range of approaches have been developed for implementing chargeback in an organization, as summarized in the figure below. The degree of complexity, degree of difficulty, and cost to implement decreases from the top of the chart [service-based pricing
(SBP)], to the bottom [high-level allocation (HLA)]. HLA is the simplest method; it uses a straight division of IT costs based on a generic metric such as headcount. Slightly more effort to implement is low-level allocation (LLA), which bases consumer costs on something more related to IT activity such as the number of users or servers. Direct cost (DC) more closely resembles a time and materials charge but is often tied to headcount as well.
