CAS-001 Question #259: Real Exam Question with Answer & Explanation
The correct answer is D: Enable 802.1x on Company B's network devices.. Company A (the acquirer) uses 802.1x/RADIUS and is importing Company B's users into its system. The integration goal is to bring Company B under Company A's authentication infrastructure. (D) Enabling 802.1x on Company B's network devices means Company B's infrastructure now uses

Options
- AEnable RADIUS and end point security on Company B's network devices.
- BEnable LDAP authentication on Company A's network devices.
- CEnable LDAP/TLS authentication on Company A's network devices.
- DEnable 802.1x on Company B's network devices.
Explanation
Company A (the acquirer) uses 802.1x/RADIUS and is importing Company B's users into its system. The integration goal is to bring Company B under Company A's authentication infrastructure. (D) Enabling 802.1x on Company B's network devices means Company B's infrastructure now uses the same authentication protocol as Company A, allowing Company B's users (once imported into Company A's RADIUS/directory) to authenticate using Company A's existing RADIUS infrastructure. This leverages the acquirer's existing investment and standard. Options B and C are wrong because they would require Company A to adopt Company B's LDAP-based system - the acquisition logic goes the other way. Option A (enabling RADIUS and endpoint security on Company B's devices) is partially right but 'endpoint security' is not the distinguishing factor here, and D is more precise in describing the correct protocol enablement. The LDAP backend in Company B can still be used by RADIUS for lookups, but the network access control protocol should be unified under 802.1x.
