Cisco Enterprise Advanced Routing and Services (ENARSI)

The Cisco Enterprise Advanced Routing and Services (ENARSI) certification exam by Cisco lasts approximately 90 minutes, with a passing score of 82%.

The Cisco Enterprise Advanced Routing and Services (ENARSI) practice question bank includes 180 questions across 3 levels (approximately 60 per level), each of which is available in three wording variants. That gives you up to 540 practice question variations to study. On every attempt, questions appear in random order and answer options are shuffled, so each session evaluates your knowledge from a fresh angle.

Cisco Enterprise Advanced Routing and Services (ENARSI) is a PROFESSIONAL level certification offered by Cisco. Preparation is considered very complex and typically requires expert level experience.

Cisco Enterprise Advanced Routing and Services (ENARSI) is organized into 4 exam domains, starting with VPN Technologies, Layer 3 Technologies, Infrastructure Security. Practice with the Certilum diagnostic engine to simulate the Cisco exam, pinpoint weak domains and measure your readiness before test day.

The Cisco Enterprise Advanced Routing and Services (ENARSI) exam has a difficulty score of 7.5/10 (Expert Level). Preparation complexity is very complex. It typically requires expert level experience. With a passing score of 82%, thorough preparation is recommended. Certilum's diagnostic engine helps you identify weak domains before test day.

• EIGRP, OSPFv2/v3, and BGP configuration and troubleshooting
• VRF and MPLS LDP implementation
• Policy-based routing and route-map logic
• DMVPN, IPsec, and FlexVPN deployment
• ACL, uRPF, CoPP, AAA, and IPv6 First Hop Security
• DHCP, QoS, NetFlow, SNMP, syslog, EEM, IP SLA, and object tracking

• CCNA-level routing and switching fundamentals
• Hands-on experience with Cisco IOS and IOS-XE CLI
• Understanding of TCP/IP, subnetting, and network security basics
• Familiarity with network monitoring and QoS concepts

High. ENARSI requires you to correlate multiple routing protocols, route maps, VRFs, encryption tunnels, and security policies in a single network scenario. You must rapidly interpret show commands, identify the root cause of failure, and select the best corrective action under time pressure.

Certilum prioritizes exam-focused scenario labs, structured revision paths, and diagnostic drills that mirror the 45-65 question format and the need to identify the fastest, safest repair in enterprise routing and VPN environments.

Create a structured lab environment using Cisco Modeling Labs or GNS3/EVE-NG with IOSv/IOL images. Practice redistribution between EIGRP, OSPF, and BGP; implement route filtering using prefix lists, route maps, and distribute lists; build DMVPN and FlexVPN tunnels; configure CoPP and AAA; and use EEM, IP SLA, NetFlow, and SNMP for monitoring. Then reinforce with timed practice exams and troubleshoot injected faults in each domain.
