This course bundle is ideal for anyone looking to launch their Cisco networking career, specifically in Cisco cyber ops and security. It consists of one Cisco Certified Technician (CCT) certification in Routing and Switching, one Cisco Certified Network Associate (CCNA) certification, one Cisco Certified CyberOps Associate certification, and one Cisco Certified Networking Professional (CCNP) certifications, specialising in Cisco security. Although there are no formal prerequisites to enrol on the CCNA, or CCNP certification courses and sit the exams, learners should have a good foundation knowledge in networking. The Cisco Certified Technician Routing and Switching (CCT Routing and Switching) certification focuses on the skills required for onsite support and maintenance of Cisco routers, switches, and operating environments. It’s a great starting point if you’re new to Cisco networking. Technicians in this area must be able to identify Cisco router and switch models, accessories, cabling, and interfaces; understand the Cisco IOS Software operating modes and identify commonly found software; and be able to use the Cisco Command Line Interface (CLI) to connect and service products. Achieving CCT Routing and Switching certification is considered the best foundation for supporting other Cisco devices and systems. Earning the CCNA is usually the first ‘major’ certification step in preparing for a career in Cisco networking technologies. To earn your CCNA certification, you only need to pass one exam – which covers a broad range of fundamentals for IT careers, based on the latest networking technologies. The Cisco Certified CyberOps Associate certification program validates the day-today, tactical knowledge and skills that Security Operations Center (SOC) teams need to detect and respond to cyber security threats. The certification validates the fundamentals needed for associate-level job roles, with one exam and one training course to help you prepare. The exam and training cover knowledge and skills related to security concepts, security monitoring, host-based analysis, network intrusion analysis, and security policies and procedures. From a recognized provider of security solutions and certifications, the CyberOps Associate certification and training program is your pathway to a career in cyber security operations. The CCNP Security certification is designed to help you prove your skills in the ever-changing landscape of security technologies. The program prepares you for today’s professional-level job roles in security technologies. One of the industry’s most respected certifications, CCNP validates the core knowledge you need while providing the flexibility to choose a focus area. To earn your CCNP Security, you must pass two exams: a core exam and a concentration exam of your choice. This course bundle includes the core exam and concentration exam. The core exam’s focus is ‘Securing Networks with Cisco Firepower Technologies‘ – Cisco CCNP Security SNCF (Exam 300-710).
