Question 930
An internal API returns a certificate for another hostname after a load-balancer migration. Which observed result BEST confirms that the security requirement is met?
Explanation
Correct Answer
A client rejects a substituted or expired certificate rather than accepting encryption to the wrong endpoint. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Encryption without authenticated identity does not rule out interception; certificates bind a public key to a verified name under a trust chain. Situation: An internal API returns a certificate for another hostname after a load-balancer migration.
Incorrect Answers
Protected traffic crosses the tunnel with authenticated peers and encrypted data even behind the intended NAT device. This outcome tests IPsec IKE and NAT traversal and is not sufficient proof of the stated requirement. Here the relevant validation is: A client rejects a substituted or expired certificate rather than accepting encryption to the wrong endpoint. Situation: An internal API returns a certificate for another hostname after a load-balancer migration.
New approved networks traverse the intended secured virtual tunnel without proliferating inconsistent policy selectors. This outcome tests Route-based versus policy-based VPN design and is not sufficient proof of the stated requirement. Here the relevant validation is: A client rejects a substituted or expired certificate rather than accepting encryption to the wrong endpoint. Situation: An internal API returns a certificate for another hostname after a load-balancer migration.
Poisoned documents or swapped model dependencies fail integrity or access checks before affecting sensitive answers. This outcome tests Embedding and model supply chain risk and is not sufficient proof of the stated requirement. Here the relevant validation is: A client rejects a substituted or expired certificate rather than accepting encryption to the wrong endpoint. Situation: An internal API returns a certificate for another hostname after a load-balancer migration.
