Case Study: 2
Contoso, Ltd
Background
Contoso, Ltd. is developing a patient monitoring solution for a hospital. The solution consists
of an Azure website and a set of mobile applications that health care providers use to monitor
patients remotely.
Monitoring devices that run the embedded version of Windows will be attached to patients.
The devices will collect information from patients and will transmit real-time continuous data
to a service that runs on Azure. The service collects and distributes data. The data that the
service provides must be accessible by the website and by the mobile applications.
Business Requirements
Patients
All patient data must be stored securely on Azure. Data security must meet or exceed Health
Insurance Portability and Accountability Act of 1996 (HIPAA) standards in the United States
and must meet or exceed ISO/ICE 27002 data security standards in the rest of the world.
Contractors
Third-party contractors will develop the mobile applications. All contractors must develop
the applications by using virtual machines (VMs) that are hosted on Azure. Only authorized
contractors and authorized IP addresses are permitted to access the VMs. The contractors can
use Near Field Communication (NFC) tags to launch Remote Desktop (RD) connections to
the VMs from NFC-enabled devices. For testing purposes, contractors must be able to run
multiple instances of mobile applications within the VMs.
Data Collection and Distribution Service
The service must monitor the patient data and send out alerts to health care providers when
specific conditions are detected. The service must send the alerts to mobile applications and
to the website in real time so that doctors, nurses, and caregivers can attend to the patient.
Partner organizations and diagnostic laboratories must be able to securely access the data and
the website from remote locations.
Current Issues
A partner that is testing a prototype of the website reports that after signing in to the website,
the partner is redirected to the settings page instead of to the home page.
The data from the patient devices is slow to appear on the website and does not always
appear. All patient devices online have active connections to the data collection service.
Technical Requirements
Contractors
All contractors will use virtual machines that are initially configured as size A3. Contractors
must sign in to the assigned VM by using IP addresses from a list of preapproved addresses.
Data Collection and Distribution Service
• The service runs Node.js in a worker role.
• The service must use at least 2048-bit encryption and must use port 8888.
• All patient information must be encrypted and stored by using a NoSQL data store.
• Data must be stored and retrieved securely by using RESTful endpoints.
• Data must NOT be stored within a virtual machine.
All deployed services must send an alert email to [email protected] when any of the
following conditions is met:
• The CPU Percentage metric is at or above 85 percent for at least 10 minutes.
• The Network In metric is at or above 2 KB for at least 10 minutes.
• The Network Out metric is at or above 2 KB for at least 10 minutes.
• The Disk Write metric is at or above 1 KB/sec for at least 30 minutes.
• The Disk Read metric is at or above 1 KB/sec for at least 30 minutes.
Website and Mobile Devices
The website must be secure and must be accessible only within the hospital’s physical
grounds. All mobile applications and websites must be responsive. All websites must produce
error logs that can be viewed remotely.
Virtual Machines
• All Azure instances must be deployed and tested on staging instances before they are
deployed to production instances.
• All deployed instances must scale up to the next available CPU instance at a CPU
usage threshold of 90 percent and scale down when the usage is below 10 percent.
Application Structure
Relevant portions of the application files are shown in the following code segments. Line
numbers in the code segments are included for reference only and include a two-character
prefix that denotes the specific file to which they belong.
###EndCaseStudy###
You need to implement tracing for the website after the website is deployed.
Which code segment should you insert at line CF13?
A.
Option A
B.
Option B
C.
Option C
D.
Option D
I think “b” is collect answer.
I think c is the correct ans
I also think B is the right answer

Wrote the 70-532 exam on 22/Feb/2016, passed with 9XX marks!
Got 56 questions in total, including 31 mixed questions and 3 case studies (8+8+9).
8 new multiple choice questions and 1 new case study (Fabrikam Concert Tickets).
I learned all new questions from passleader 70-532 exam dumps (VCE and PDF here: https://tr.im/vM3dG) (105q dumps), all new questions are same as my real test, really helpful!
P.S. Microsoft have announced that the 70-532 exam will get many changes from March 10, 2016, including “Website –> Web Apps”, “Windows PowerShell –> Azure PowerShell”, “access control list (ACL) –> Network Security Groups (NSG)”, “cloud service –> virtual network” and so on!!!
get lost!
Stop spamming this site.
B is the correct answer.
writeif does not write anything unless the condition is True!
https://msdn.microsoft.com/en-us/library/system.diagnostics.trace.writeif(v=vs.110).aspx
B is my vote.
B makes most sense. But it could also be C, if we assume that the environment is configured in such way that only Errors level are logged and not Info.
“All websites must produce error logs that can be viewed remotely.”
As it says in the question “you need to implement tracing.”
B fits perfect for line 13.
Mentions ‘tracing,’ nothing about errors. Thinking “B” as it is the TraceInformation() method.
C is correct
I’ve seen this question before but without Trace.Information (option B) replaced with Trace.Assert.
Therefore I am going with option c which is the only viable solution.
We must provide tracing requested by the case study (“all websites must produce
error logs”). So I say C.
The 70-532 exam has been updated since Nov/2016! I took the exam few days ago and luckily passed with a good score of 9xx!
Some tips for passing the 70-532 exam (wish help you all):
1. Watch the MVA course on 70-532 completely
2. Learn the book: Exam Ref 70-532 Developing Microsoft Azure Solutions deeply
3. Practice premium 70-532 dumps from: http://www.passleader.com/70-532.html (105q VCE and PDF dumps)
4. Learn new/changed objectives: Azure Resource Manager (ARM), Azure Functions, Document DB, Logic Apps, and many more newer Azure features and services
Remember to practice PowerShell Commands again and again!!!
And, the premium 70-532 dumps that I learned are free here:
https://doc.co/FscFAu
Recommend to learn it, for wrong answers have been corrected and all new objectives have been covered, the most valid 70-532 dumps, I think.
Good Luck! Cool Guy!
Passed 70-532 in new format few days ago! Got 3 Case Studies (each contains 8 Qs): Web-based Solution, Fabrikam (NEW Case Study) and so on.
1. Studying the code samples deeply, Azure documents of all. Taking confidence with Powershell scripts for Azure.
2. Learning details on Azure storage Files, SAS, Access Policies, Various tiers of Azure SQL, VMs, Storages, Redis and their specifications, best practices of setting up SQL on VMs, VNET/Networking/IPs/Load BalacingApp Gateways/VPN setup/Express Routing concepts … etc.
3. Reading the 70-532 book (Exam Ref 70-532 Developing Microsoft Azure Solutions), watching MVA videos.
(ATTENTION!!! The test format had been changed, you can’t scroll through the questions. You have to complete each section at a time before you can move on to the next.)

A. Public cloud
B. Private community cloud
C. Private cloud
D. Community cloud
Answer: C
Explanation:
Rapid elasticity is a cloud computing term for scalable provisioning, or the ability to provide scalable services. Software that can scale in a private cloud faces two security related issues:
– Although the private cloud infrastructure can enable rapid elasticity in the supply of virtual resources, hosted applications and services must be designed correctly if they are to function securely when they are scaled out.
– Hosted applications and services that initiate scaling requests automatically based on monitored demand or a timetable must perform these operations without impacting their own or other services availability within the cloud.
