JN0-1101: Design, Associate (JNCDA)

Business-continuity planning requires an inventory and understanding of the network and its dependencies, risk assessment to identify threats and impacts, and testing or exercises to validate that recovery procedures will work. NIST contingency-planning guidance likewise incorporates risk management and testing, training, and exercises as essential planning activities.

The JATP Appliance provides Juniper Advanced Threat Prevention as a virtualized on-premises solution. It can analyze and block known and zero-day malware while keeping file analysis within the local environment, unlike ATP Cloud/Sky ATP, which sends files to a cloud service for analysis.

The WAN edge forms the boundary to external WAN or service-provider networks, and the aggregation tier provides the interdomain aggregation and policy boundary before traffic enters the internal core. The core is intended for high-speed internal transport rather than direct connections to untrusted domains.

vSRX is a virtualized next-generation firewall intended for virtualized environments and can enforce security for east-west traffic between virtual machines in a data center.

An 802.1X authenticator is the network-access device that controls access on the supplicant-facing port and forwards EAP authentication exchanges to the RADIUS authentication server. The EX Series switch performs that role; endpoints are supplicants and the RADIUS server is the authentication server.
