CCNA: Cisco Certified Network Associate — Question 190

Which two statements about eBGP neighbor relationships are true? (Choose two.)

Answer options

• A. The two devices must reside in different autonomous systems
• B. Neighbors must be specifically declared in the configuration of each device
• C. They can be created dynamically after the network statement is configured
• D. The two devices must reside in the same autonomous system
• E. The two devices must have matching timer settings

Correct answer: A, B

Explanation

Option A is correct because eBGP neighbors must indeed be in different autonomous systems to establish a relationship. Option B is also correct as each device must explicitly configure its neighbors. Options C, D, and E are incorrect because eBGP neighbors cannot be created dynamically, they must be from different autonomous systems, and matching timer settings are not a requirement for establishing eBGP relationships.
