Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 274

Which of the following are commonly used ports when implementing RADIUS based authentication and accounting? (Choose two.)

Answer options

• A. UDP port 1644 for authentication
• B. UDP port 1812 for authentication
• C. TCP port 1812 for authentication
• D. UDP port 1813 for accounting
• E. TCP port 1813 for accounting
• F. UDP port 1644 for accounting

Correct answer: B, D

Explanation

UDP port 1812 is the standard port used for RADIUS authentication, making option B correct. For accounting, UDP port 1813 is the designated port, which is why option D is also correct. The other options either reference incorrect ports or use TCP instead of the correct UDP for RADIUS functionality.
