大家来批批一套外企面试题,掂掂自己的分量!
前几天面试一家公司,给我发了一份题,说实话很讨厌老要人做题的公司,又不是刚毕业学生.不过看了看题,觉得题目还出的不错,大部分题感觉都能答点,但又都不确定,欢迎大家都来试试.
Question 1 - System Architecture
Consider the following system deployment or design:
User--------------Web server--------------Database
Part a - Rate the Design
How do you rate this system in regards to the following criteria?
Indicate for each criteria resiliency, performance and scalability whether you consider the design of the system displayed above as poor, average or superior. Select ‘n/a’ if you feel the information is insufficient to make a choice.
Resiliency0 n/a0 poor0 average0 superior
Performance0 n/a0 poor0 average0 superior
Scalability0 n/a0 poor0 average0 superior
Part b - Explain the Ratings
For the choices where you selected either poor or superior, specify one relevant reason for you selection.
Resiliency
Performance
Scalability
Part c - Suggest Improvements
For the choices where you selected either poor or average, suggest one or two options to improve the design of the system. You may also use the space below to draw a picture.
Resiliency
Performance
Scalability
Question 2 - .NET Unmanaged Code
What would be a valid reason for using unmanaged code within a .NET application that otherwise relies on managed code only?
Question 3 - Shopping Cart & HTTP Sessions
Retail sites that offer products for purchase frequently provide a “shopping cart” feature. It allows users to add multiple items to a virtual shopping cart and to purchase the items in one transaction rather than individually.
This kind of feature is often implemented using one of the following two approaches.
A Cookies Only:All of the session data is stored in HTTP browser cookies.
B Cookies & Database:A session key for each user is stored in a HTTP browser cookie while the values are persisted in a database.
Part a - Rate the Options
How do these approaches compare in terms of the following criteria:
Resiliency0 A better0 B better0 Both equal
Performance0 A better0 B better0 Both equal
Scalability0 A better0 B better0 Both equal
Part b - Session Data Size
Which of the two solution is more appropriate if the amount of session data is
Always less than 10 bytes0 A 0 B0 Both equal
Always less than 1 KB0 A 0 B0 Both equal
Always less than 10 KB0 A 0 B0 Both equal
May exceeed 10 KB0 A 0 B0 Both equal
May exceeed 100 KB0 A 0 B0 Both equal
Question 4 - Shopping Cart & Web Services
This question refers again to the shopping cart feature described in the previous question.
How would you design the same shopping cart functionality if it is provided as a SOAP web service rather than a web site? Event though the SOAP service is being accessed through HTTP (HTTP transport binding,) cookies may not be used.
Briefly describe your suggestion below.
Question 5 - HTTP Caching Headers
The HTTP standard specifies a number of headers that are used to determine if and how response data can be cached.
List Names of Caching Headers
Part a - Examples
List two or three of the most relevant headers.
Part b - Caching Headers & HTTP Methods
Indicate which of the following HTTP request methods caching may apply:
HTTP GET0 Yes0 No
HTTP POST0 Yes0 No
HTTP HEAD0 Yes0 No
HTTP PUT0 Yes0 No
Question 6 - .NET Virtual Machine
Part a - Crashing a .NET Virtual Machine
If asked to do so, how would you crash a .NET process (Java process) using managed code only?
Part b - Debugging a .NET Virtual Machine
A .NET application frequently runs out of memory and crashes. What approach and/or what tools would you take to analyze and fix the problem.
