Implementing and Configuring Cisco Identity Services Engine (SISE) Free Practice Test — 30 Questions

Question 1

Consider a scenario within an enterprise network managed by Cisco Identity Services Engine (ISE). A new contingent worker, designated as \'External Consultant,\' attempts to access sensitive financial reports stored on a segregated server. ISE successfully authenticates the worker\'s device and assigns it to Security Group Tag (SGT) 15, representing \'External Access.\' A pre-defined Trustsec policy, configured on the network infrastructure and managed by ISE, explicitly permits SGT 15 access to general company resources but strictly denies any access to the \'Financial Data\' server, which is tagged with SGT 50 (\'Restricted Financials\'). Given these configurations, what is the most probable outcome of the External Consultant\'s access attempt to the \'Financial Data\' server?

Accepted Answer

The access attempt will be denied because the Trustsec policy explicitly prohibits SGT 15 from accessing resources tagged with SGT 50.

Question 2

A large metropolitan hospital network is experiencing an increase in unauthorized access attempts to its patient data repositories, coinciding with a recent audit that highlighted potential non-compliance with HIPAA security standards. The IT security team is tasked with strengthening their network access control mechanisms and ensuring a verifiable audit trail for all data access.
