Q1. You are designing an ASP.NET web application that allows members of the Administrators

role to edit content by using a HyperLink control on each page named EditHyper

Link. You do not want nonadministrators to discover the location of the administration

pages. Which approach should you recommend?

server. You need to design the application to keep users notified of the provisioning

progress. Which approach should you recommend?

JavaScript to connect to the server hosting the virtual machines and initiate the

provisioning.

D. On the client, use JavaScript to launch a separate asynchronous process for each

virtual machine to be provisioned. Within each process, request a page from the

web server that provisions a virtual machine.

Q56. You are planning the deployment of a new ASP.NET web application. You want to

deploy the application as a single DLL. Which approach should you recommend?

A. Use the Publish Web tool.

B. Use the ASP.NET Compilation Tool.

C. Create a web deployment package.

D. Create a Web Deployment Project.

Answer : D

Q57. You are planning the deployment of a new ASP.NET web application to several servers

running IIS 7.5. Because the web servers are protected by firewalls, you need to send

the application to systems administrators for installation. You need to deploy a Microsoft

SQL Server Express Edition database with the application. Which approach should

you recommend?

A. Use the Publish Web tool.

B. Use the ASP.NET Compilation Tool.

C. Create a web deployment package.

D. Create a Web Deployment Project.

Answer:D

Q58. You are planning to deploy a new .NET 4.0 web application to a web server running

IIS 7.5. Currently, the web server has several .NET 2.0 applications running on it, and

those applications have not been tested with the .NET Framework. How can you

deploy the new application to minimize the risk of affecting the existing applications?

A. Add the new application to the existing application pool, but update the application

pool to .NET 4.0.

B. Add the new application to a new application pool.

C. Configure the application pool to use classic pipeline mode.

D. Configure the new application with a separate web.config file.

Answer:B

Q59. You are planning to deploy a new .NET 4.0 web application developed on your local

computer to a staging environment for testing. After the quality assurance team

approves the application in the staging environment, you need to deploy it to the

production environment. The staging and production environments should not display

detailed error messages or allow tracing. Additionally, they each require different

connection strings than you use on your local computer. You will need to deploy the

application multiple times to each environment, and you want to minimize the effort

required with each deployment. Which solution do you recommend? (Choose all that

apply. Each answer forms part of the complete solution.)

A. Set the <customError> mode to RemoteOnly.

B. Use the ConfigSource attribute to store the connection strings in a separate file.

C. Edit the Web.Release.config file.

D. Create a Web.Staging.config transform file.

Answer : C,D

Q60. You are planning to deploy a new .NET 4.0 web application. The systems administration

management has described that they have a separate group who administers

databases and database-related settings, and that this group should be able to change

the connection strings for the application but not modify other settings. The new

application stores the connection strings in the web.config file. Which solution do you

recommend? (Choose all that apply. Each answer forms part of the complete solution.)

A. Move the setting to a separate .config file.

B. Create a new transform file for the production environment.

C. Grant the database administrator read-only privileges to the web.config file and

write privileges to the new file.

D. In the web.config file, specify the new file using the ConfigSource attribute.

Answer : A,C,D

Q61. You are planning to scale out a web application to provide increased capacity. Currently,

the web application runs on a single web server with a separate database server.

The application uses session state to track users throughout their session. How can you

add web servers while ensuring session state continues to work as expected? (Choose

two. Each answer forms a complete solution.)

A. Use the InProc session state.

B. Use a separate session state server.

C. Configure the load-balancing mechanism for server affinity.

D. Configure the load-balancing mechanism to distribute requests evenly between

the servers.

Answer : C,D

Q62. Recently, a web application failed because it received too many requests in a short

amount of time. Currently, the web application runs on two servers: a single web server

and a single database server. Performance analysis revealed that the web server was

at 100 percent processor utilization at the time of the failure. You would like to allow

the web application to handle more requests without increasing your management or

software licensing costs. Which approaches would you recommend? (Choose all that

apply. Each answer forms part of the complete solution.)

A. Add processors to the web server.

B. Add an additional web server, and then configure round-robin DNS.

C. Use performance-tuning techniques to improve the efficiency of the ASP.NET code.

D. Use the SQL Server Profiler to improve the efficiency of the database indexes.

Answer : A,C

Q63. You are responsible for a web application that runs on a single server. You host the

server at your local data center, which has a single Internet connection. After a recent

application outage, management has decided to eliminate all single points of failure in

the application architecture. Which approach should you recommend? (Choose all that

apply. Each answer forms part of the complete solution.)

A. Add multiple network adapters to the web server, and then connect them to separate

network switches.

B. Deploy the application to a cloud-hosting provider.

C. Deploy a second web server to the same data center, and then use a hardware

load balancer.

D. Deploy a second web server to a different data center, and then configure roundrobin

DNS.

Answer:C,D

Q64. You are designing an ASP.NET application. The systems administration team has

requested that their monitoring system be notified each time the application starts.

Their monitoring system can read events from the event log. You would like to

minimize the amount of code you need to write. Which approach should you

recommend?

A. In Application_Start, add an event to the event log.

B. Create a custom health-monitoring event class, and configure a standard provider.

C. Use a standard health-monitoring event class, and configure a custom provider.

D. Use a standard health-monitoring event class and provider.

Answer:D

Objective 6.4: Design a Health-Monitoring Strategy Chapter 6 249

Q65. You are designing an ASP.NET application. The systems administration team has a

mobile phone that one member of the staff uses to be notified of outages. In the

event your application receives more than 100 failed logon attempts in one minute,

they would like the application to send a message directly to the on-call mobile phone

using a web service on the local network. You would like to minimize the amount of

code you need to write. Which approach should you recommend?

A. Use a standard health-monitoring event class and provider.

B. Create a custom health-monitoring event class, and configure a standard provider.

C. Use a standard health-monitoring event class, and configure a custom provider.

D. Use a custom health-monitoring event class, and configure a custom provider.

Answer:C

Q66. You are designing an ASP.NET application. The systems administration team has given

you a list of events they would like to be able to monitor using ASP.NET health monitoring.

Which of the following events will require developing a custom class?

A. Receiving more than 500 requests in one minute.

B. An authenticated user attempts to access a restricted portion of the application

more than five times in one minute.

C. A web service takes more than ten seconds to respond more than five times in two

minutes.

D. The application starts more than ten times in one minute.

Answer:C
