Description of Business in Business Architecture should address

  1. Business goals, Objectives, Organization structure and functions

  2. Business goals, Objectives, Architecture principles

  3. Business goals, Objectives, Strategic drivers

  4. None of the above


Correct Option: A

AI Explanation

To answer this question, we need to understand the purpose of Business Architecture and what it entails.

Business Architecture is a discipline within enterprise architecture that focuses on the structure and operation of an organization. It seeks to align the business strategy and goals with the organization's structure, processes, and capabilities.

In the context of describing the business in Business Architecture, it should address several key aspects, including:

A. Business goals, objectives, organization structure, and functions - This option is correct. Describing the business in Business Architecture should include the organization's goals and objectives, as well as its structure and functions. This helps provide a comprehensive understanding of the business's purpose and how it operates.

B. Business goals, objectives, architecture principles - This option is not the correct answer. While architecture principles may be part of Business Architecture, they are not the only components that should be addressed when describing the business.

C. Business goals, objectives, strategic drivers - This option is not the correct answer. While strategic drivers are important considerations in Business Architecture, they do not encompass all the necessary aspects of describing the business.

D. None of the above - This option is not the correct answer. Option A is the correct answer as it includes all the key components that should be addressed when describing the business in Business Architecture.

Therefore, the correct answer is A) Business goals, Objectives, Organization structure, and functions.

  5. security


Correct Option: C
  1. DES

  2. RC4

  3. Block ciphers using Electronic Code Book (ECB) mode

  4. AES


Correct Option: D
Explanation:

To determine which Algorithm/Encryption method is safest for use, we need to evaluate each option and determine its level of security.

A. DES (Data Encryption Standard) is an encryption method that uses a symmetric key algorithm. It was widely used in the 1970s and 1980s but has since been replaced by more secure encryption methods. DES is vulnerable to brute-force attacks, which can decrypt the encrypted message by trying all possible keys.

B. RC4 (Rivest Cipher 4) is a symmetric key stream cipher that was widely used in the past but is now considered insecure. It has been found to have many vulnerabilities, including biases in the key-scheduling algorithm and statistical weaknesses in the keystream.

C. Block ciphers using Electronic Code Book (ECB) mode is a method of encrypting data in blocks using a symmetric key algorithm. However, it is not considered secure because it is vulnerable to certain attacks, such as pattern attacks, where the same plaintext block is encrypted to the same ciphertext block.

D. AES (Advanced Encryption Standard) is a symmetric key algorithm that is widely used and considered to be secure. It has a key size of 128, 192, or 256 bits and uses a block cipher to encrypt data. AES has been extensively tested and is currently used by many organizations, including the US government, for encryption.

Therefore, the safest Algorithm/Encryption method for use is:

The Answer is: D. AES
