JNCIP-Cloud: Juniper Networks Certified Professional – Cloud — Question 1

You are having problems establishing an IPsec tunnel between two SRX Series devices.
What are two explanations for this problem? (Choose two.)

Answer options

• A. proposal mismatch
• B. antivirus configuration
• C. preshared key mismatch
• D. TCP MSS clamping is disabled

Correct answer: A, C

Explanation

The correct answers are A and C because a proposal mismatch indicates that the configurations do not match on both ends of the IPsec tunnel, while a preshared key mismatch means the keys used for authentication do not match. Options B and D are not relevant to IPsec tunnel establishment issues.
