CCIE Enterprise Infrastructure Domains
Our practice test covers all domains of the CCIE Enterprise Infrastructure track:
Domain 1: Network Infrastructure (25%)
- Layer 2 Technologies: VLANs, STP (RSTP, MST), EtherChannel, VTP
- Layer 3 Routing: OSPF, EIGRP, BGP (iBGP, eBGP), route redistribution
- Advanced OSPF: Areas, virtual links, LSA types, route summarization
- BGP Advanced: Path attributes, route reflectors, confederations, filtering
- Multicast: IGMP, PIM (Dense, Sparse, SSM), RP configuration
- First Hop Redundancy: HSRP, VRRP, GLBP configuration and tuning
Answer: Configure an OSPF virtual link through Area 1 or Area 2 to connect Area 3 to the backbone. Virtual links use a transit area to extend Area 0 connectivity. The transit area must be a standard area (not stub or NSSA).

Domain 2: Software Defined Infrastructure (25%)
- SD-WAN (Viptela): vManage, vBond, vSmart, vEdge architecture
- SD-Access: DNA Center, fabric design, control plane (LISP), data plane (VXLAN)

Answer: LISP (Locator/ID Separation Protocol) serves as the control plane protocol in SD-Access, providing host tracking and mobility. It separates endpoint identity (EID) from network location (RLOC), enabling endpoints to move across the fabric while maintaining connectivity. The fabric control plane node acts as the LISP Map-Server/Map-Resolver.
Domain 3: Transport Technologies and Solutions (20%)
- MPLS: LDP, RSVP-TE, label distribution and forwarding
- MPLS VPNs: L3VPN (VRF, RD, RT), L2VPN (VPLS, EVPN)

- IPsec VPN: IKEv1/IKEv2, crypto maps, VTI, GRE over IPsec
- Segment Routing: SR-MPLS, SRv6, traffic engineering
- QoS: Classification, marking, queuing, policing, shaping
Domain 4: Infrastructure Security (15%)
- Device Hardening: Control plane policing, management plane protection
- AAA: TACACS+, RADIUS, local authentication
- Access Control: Standard/extended ACLs, VACL, RACL
- Network Security: 802.1X, MAB, WebAuth, DHCP snooping, DAI
- Firewall Integration: Zone-based firewall concepts
- Secure Network Access: TrustSec, SGT, SGACL
Domain 5: Infrastructure Automation and Programmability (15%)
- Network Programmability: Python, APIs (REST, NETCONF, RESTCONF)
- Automation Tools: Ansible, Terraform for network automation
- Data Models: YANG models, OpenConfig, Cisco native models
- Cisco DNA Center APIs: Intent APIs, assurance APIs
- Scripting: Python scripts for network operations
- CI/CD: Pipeline concepts for network infrastructure

The CCIE Certification Journey
Understanding the complete CCIE path is essential for planning your preparation:
Step 1: ENCOR Written Exam (350-401)
- Questions: 90-110 questions
- Duration: 120 minutes
- Cost: $400 USD
- Validity: Written exam pass is valid for 3 years to attempt the lab
- Note: This is the same exam as the CCNP Enterprise core
Step 2: CCIE Lab Exam
- Duration: 8 hours in a single day
- Modules: Design → Deploy → Operate and Optimize
- Cost: $1,600 USD per attempt
- Location: Cisco lab facilities worldwide
- Equipment: Real Cisco routers, switches, and software
- Pass Rate: ~20-30% first attempt
CCIE Lab Exam Breakdown
The 8-hour lab exam consists of three integrated modules:
Module 1: Design (No Scored Points)
Create network designs based on given requirements. While not directly scored, you must complete design tasks to proceed. The designs inform your configuration work.
Module 2: Deploy
Configure network infrastructure from scratch based on requirements. This includes routing protocols, switching, VPNs, security, and automation. All configurations must be completed without internet access.
Module 3: Operate and Optimize
Troubleshoot complex network issues and optimize configurations. You'll diagnose problems across multiple technologies and implement fixes within time constraints.

Frequently Asked Questions
What is the CCIE certification process?
CCIE requires passing a qualifying written exam (ENCOR 350-401) followed by an 8-hour hands-on lab exam. The written exam is the same as the CCNP Enterprise core. The lab tests real-world design, deployment, and troubleshooting skills.
How long does it take to prepare for the CCIE lab?
Most candidates spend 12-24 months preparing, with 500-1000+ hours of hands-on practice. This typically includes studying, lab practice, and potentially attending bootcamps. Full-time focused preparation can reduce this to 6-9 months.
What is the CCIE lab exam format?
The 8-hour lab exam has three modules: Design (unscored but required), Deploy (configuration), and Operate/Optimize (troubleshooting). You work on real Cisco equipment without internet access. The exam costs $1,600 per attempt.
What is the CCIE lab pass rate?
First-time pass rates are approximately 20-30%. Many candidates attempt the lab 2-3 times. This rigor is why CCIE represents the top 1% of networking professionals (~65,000 active CCIEs worldwide).
What is the average CCIE salary?
CCIE holders earn $150,000-$220,000 annually. Senior architects and consultants can earn $200,000-$300,000+. Independent consultants charge $200-$350/hour.
How long is CCIE certification valid?
CCIE is valid for 3 years. Recertify by passing any CCIE lab, the written exam plus 40 CE credits, earning 80 CE credits, passing two professional exams, or passing CCDE exams.
What CCIE tracks are available?
Tracks include: Enterprise Infrastructure (most popular), Enterprise Wireless, Data Center, Security, Service Provider, Collaboration, and DevNet Expert. Each has a dedicated lab exam.
Should I get CCNP before CCIE?
Yes, CCNP-level knowledge is essential. The CCIE qualifying exam (ENCOR) is the CCNP core exam. Most successful candidates have 5+ years experience and hold CCNP or equivalent.
