NEW QUESTION: 1
You are developing an ASP.NET MVC application that uses forms authentication. The application uses SQL queries that display customer order data.
Logs show there have been several malicious attacks against the servers.
You need to prevent all SQL injection attacks from malicious users against the application.
How should you secure the queries?
A. Implement parameterization of all input strings.
B. Check the input against patterns seen in the logs and other records.
C. Escape single quotes and apostrophes on all string-based input parameters.
D. Filter out prohibited words in the input submitted by the users.
Answer: A
Explanation:
SQL Injection Prevention, Defense Option 1: Prepared Statements (Parameterized Queries) The use of prepared statements (aka parameterized queries) is how all developers should first be taught how to write database queries. They are simple to write, and easier to understand than dynamic queries. Parameterized queries force the developer to first define all the SQL code, and then pass in each parameter to the query later. This coding style allows the database to distinguish between code and data, regardless of what user input is supplied.
Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker.

Topic 5, Flight Information
Background
You are developing a flight information consolidation service. The service retrieves flight information from a number of sources and combines them into a single data set. The consolidated flight information is stored in a SQL Server database. Customers can query and retrieve the data by using a REST API provided by the service.
The service also offers access to historical flight information. The historical flight information can be filtered and queried in an ad hoc manner.
The service runs on a Windows Azure Web Role. SSL is not used.
Business Requirements
- A new data source for historical flight information is being developed by a contractor located on another continent. - If a time zone is not specified, then it should be interpreted as Coordinated Universal Time (UTC). - When you upgrade a service from a staging deployment to a production deployment, the time that the service is unavailable must be minimized. - The default port must be used for HTTP.
Technical Requirements
The existing sources of flight information and the mechanism of exchange are listed below. - Blue Yonder Airlines provides flight information in an XML file. - Consolidated Messenger provides flight information in a Microsoft Access
database that is uploaded every 12 hours to the service using SFTP. The company uses port 22 for SFTP.
- Margie's Travel provides and consumes flight information using serialized ADO.NET DataSets. Data is periodically synced between the service and Margie's Travel.
- Trey Research provides data from multiple sources serialized in proprietary binary formats. The data must be read by using .NET assemblies provided by Trey Research. The assemblies use a common set of dependencies. The current version of the Trey Research assemblies is 1.2.0.0. All assemblies provided by Trey Research are signed with a key pair contained in a file named Trey.snk, which Trey Research also supplies.
- The application specification requires that any third-party assemblies must have
strong names.

NEW QUESTION: 2
Scenario
Please read this scenario prior to answering the question
Your role is that of Lead Enterprise Architect within the headquarters of a large fast food chain. The chain manages over 6000 restaurants across 24 countries. Each restaurant in the chain is an independently owned and operated franchise. Many of the restaurants use have been with the franchise since its initial startup phase and still use the first generation IT systems deployed over 15 years ago.
The CEO of the chain has stated his concerns about the inefficiencies of the current systems and identified the need to change. He has defined a new strategic vision that will enhance the business by providing its franchisees new support services to help them complete with the increasing competition from coffee shops. This strategy is part of the long-term commitment to enhance the brand image and increase revenue for the chain. He has also stated that he expects improved financial results by the end of the current fiscal year.
These changes will provide the chain with improved products, including healthier alternatives in their menu, and more efficient operations. The addition of a corporate-wide data warehouse will provide analytics that will enable the marketing group to improve its ability to target advertising and new products to specific regions.
The chain has a mature enterprise architecture practice based in its headquarters and uses TOGAF 9 as the method and guiding framework. The CIO is the sponsor of the activity.
In planning this change, the Chief Architect engaged the services of a well-known consulting firm that specializes in business strategy. An initial study has been conducted to identify the strategic changes needed to implement the CEO's vision. This recently completed with approval of a strategic architecture encompassing the entire chain, including detailed requirements and recommendations.
Based on the recommendations from the initial study, the chain has taken the decision to adopt a packaged suite of integrated applications that is tailored to the needs of the franchise.
Refer to the scenario
You have been asked by the Chief Architect to propose the best approach for architecture development to realize the CEO's vision.
Based on TOGAF, which of the following is the best answer?
A. You propose that the team focus on defining the target architecture by going through the architecture definition phases (B-D). This is because the initial study identified the need to change. This will ensure that the change can be defined in a structured manner and address the requirements needed to realize the vision.
B. You propose that the team focus on architecture definition, with a specific emphasis on understanding the strategic change parameters of the business strategy. Once understood, the team will be in the best position to identify the requirements, drivers, issues, and constraints for this engagement. You would ensure that the target architecture addresses non-functional requirements so as to ensure the target architecture is robust and secure.
C. You propose that the target architecture is defined first, followed by transition planning. This is because the vision is well understood and the strategic architecture agreed. The target first approach will ensure that the current problems and inefficiencies of the baseline architecture are not carried forward, and that the proposed solution addresses the requirements identified in the initial study.
D. You propose that this engagement define the baseline architecture first in order to assess the current infrastructure capacity and capability. The initial priority is to understand the problem. Then the focus should be on transition planning and architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the vision.
