1In the Cisco Enterprise Architecture, which layer is responsible for high-speed packet switching and aggregation from access layer devices?

A.Core layer

B.Distribution layer

C.Access layer

D.Data Center layer

Explanation: The distribution layer aggregates traffic from access layer switches and provides policy-based connectivity. It serves as the boundary between Layer 2 switching and Layer 3 routing, implementing routing, filtering, and QoS policies. The core layer provides high-speed backbone connectivity, while the access layer connects end devices.

2In a Cisco SD-Access fabric, what is the role of the Control Plane Node?

A.It performs all data forwarding for the fabric

B.It tracks all endpoint locations and maintains the host tracking database

C.It provides wireless LAN controller services only

D.It acts solely as a DHCP server for fabric endpoints

Explanation: The Control Plane Node in Cisco SD-Access uses LISP (Locator/ID Separation Protocol) to maintain the host tracking database, which maps endpoint identifiers (EIDs) to their current locations (RLOCs). This enables seamless mobility and allows the fabric to route traffic to endpoints regardless of their physical location within the network.

3Which OSPF LSA type describes routes to external destinations when redistributing from another routing protocol?

A.Type 1 (Router LSA)

B.Type 3 (Summary LSA)

C.Type 5 (External LSA)

D.Type 7 (NSSA External LSA)

Explanation: Type 5 LSAs (External LSAs) are generated by ASBRs (Autonomous System Boundary Routers) to advertise routes redistributed from external routing protocols into OSPF. These LSAs are flooded throughout the entire OSPF domain (except stub areas) and include external route metrics and forwarding addresses.

4What is the function of IP Source Guard?

A.To encrypt IP packets

B.To prevent IP spoofing by filtering traffic based on IP-to-MAC bindings from DHCP Snooping

C.To monitor IP traffic only

D.To replace the need for ACLs

Explanation: IP Source Guard prevents IP spoofing attacks by filtering traffic based on the IP-to-MAC-to-port bindings learned through DHCP Snooping or static configuration. It blocks traffic with source IP addresses that do not match the expected bindings, preventing attackers from impersonating legitimate devices.

5What is the purpose of YANG (Yet Another Next Generation) in network automation?

A.To execute Python scripts on network devices

B.To define data models for network device configuration and operational state

C.To replace SNMP completely

D.To encrypt network management traffic

Explanation: YANG is a data modeling language used to model configuration and state data manipulated by the NETCONF protocol. It provides a standardized, vendor-neutral way to represent network device configurations and operational data, enabling consistent programmatic interaction with network devices.

6Which high availability mechanism allows a switch to use multiple links simultaneously for both data forwarding and redundancy without creating Layer 2 loops?

A.Spanning Tree Protocol (STP)

B.Virtual Port Channel (vPC)

C.UniDirectional Link Detection (UDLD)

D.PortFast

Explanation: Virtual Port Channel (vPC) allows two Cisco Nexus switches to act as a single logical switch to a downstream device, enabling all links in the port channel to forward traffic simultaneously without creating Layer 2 loops. Unlike STP which blocks redundant paths, vPC uses them for active-active forwarding.

7What is the main difference between traditional campus design and Cisco SD-Access fabric?

A.SD-Access eliminates the need for physical switches

B.SD-Access separates the control plane from the data plane using LISP and VXLAN

C.SD-Access only supports wireless networks

D.Traditional campus design provides better security than SD-Access

Explanation: Cisco SD-Access implements a fabric-based architecture that separates the control plane (using LISP for endpoint tracking) from the data plane (using VXLAN for encapsulation). This separation enables network virtualization, micro-segmentation, and seamless mobility that traditional campus designs cannot provide.

8In IS-IS routing, what is the purpose of the System ID?

A.To identify the routing process

B.To uniquely identify each router in the IS-IS domain

C.To define the IS-IS area number

D.To encrypt IS-IS messages

Explanation: The System ID in IS-IS uniquely identifies each router (intermediate system) within the routing domain. Combined with the area address and N-selector, it forms the NSAP (Network Service Access Point) address that IS-IS uses for routing decisions.

9What is the purpose of VLAN Access Control Lists (VACLs)?

A.To encrypt VLAN traffic

B.To filter traffic within a VLAN (intra-VLAN) as it passes through the switch

C.To prevent VLAN hopping

D.To assign ports to VLANs

Explanation: VACLs (VLAN ACLs) filter traffic within a VLAN as it passes through the switch fabric, including intra-VLAN traffic that would not normally be seen by routed interfaces. Unlike RACLs (Router ACLs) that filter routed traffic, VACLs can filter Layer 2 traffic within the same VLAN.

10What is the purpose of the Cisco IOS-XE Guest Shell?

A.To provide a secure environment for running Python scripts and Linux utilities directly on the switch

B.To allow unauthorized users to access the device

C.To replace the Cisco IOS CLI

D.To disable all security features

Explanation: Guest Shell is a Linux container environment included in Cisco IOS-XE that allows network administrators to run Python scripts, install Linux packages, and execute utilities directly on the network device. This enables on-box automation, custom monitoring scripts, and troubleshooting tools without needing external servers.

CCIE Enterprise Study Tips from Top Performers

1Spend most of your time in the 30% and 25% domains first: Network Infrastructure and Software-Defined Infrastructure are the center of the lab blueprint.

2Practice configuration and troubleshooting as one workflow. CCIE tasks rarely reward isolated memorization if you cannot validate outcomes quickly.

3Know LISP, VXLAN, EVPN, SD-Access, and SD-WAN roles cold enough that you can explain control-plane and data-plane behavior from memory.

4Rehearse redistribution, BGP policy, and OSPF edge cases repeatedly because transport mistakes often cascade into bigger troubleshooting failures.

5Treat automation as operational tooling, not a side topic: know how to read YANG data, use NETCONF or RESTCONF, and automate common changes safely.

6Build timing discipline with mixed mock labs. Expert-level candidates lose attempts when they understand the technology but burn too much time on validation and recovery.

Frequently Asked Questions

What is the CCIE Enterprise Infrastructure exam format?

CCIE Enterprise Infrastructure is not a single multiple-choice test. You must first pass the qualifying 350-401 ENCOR written core exam and then pass the CCIE Enterprise Infrastructure lab, which Cisco lists as an 8-hour hands-on expert lab. Cisco does not publish a fixed lab task count, so you should prepare for a scenario-driven practical assessment rather than a known number of items.

Does Cisco publish a CCIE Enterprise Infrastructure passing score?

No. Cisco does not publish fixed passing scores for the qualifying core exam or the CCIE lab. Cisco reports results as pass or fail, which is why serious preparation should focus on blueprint coverage, speed, accuracy, and repeatable troubleshooting rather than trying to target a public numeric threshold.

What changed for CCIE Enterprise Infrastructure in 2026?

As of March 10, 2026, I did not find a new CCIE Enterprise Infrastructure lab blueprint beyond v1.1, which became effective on September 20, 2023. The notable 2026 Cisco changes around this path are operational: Cisco began accepting Cisco Learning Credits for expert-level labs in February 2026, stopped selling lab vouchers, and updated the qualifying ENCOR core exam to v1.2 effective March 19, 2026 as wireless content moved to Cisco's separate wireless track.

Which CCIE Enterprise Infrastructure domains matter most?

The biggest scoring weight is Network Infrastructure at 30%, followed by Software-Defined Infrastructure at 25%. Together those two domains make up 55% of the current lab blueprint, so your strongest return on study time usually comes from campus design and operations, SD-Access, SD-WAN, overlays, and large-scale troubleshooting in those environments.

How long should I study for CCIE Enterprise Infrastructure?

Most candidates who are already solid at the CCNP Enterprise level still need months of deliberate practice. A realistic plan is 350-500 hours focused on blueprint labs, timed troubleshooting, automation basics, and repeated full-stack enterprise scenarios. You should not schedule the lab until you can solve routing, policy, overlay, and security tasks quickly without pausing to look up basic syntax.

How is CCIE Enterprise Infrastructure different from CCNP Enterprise?

CCNP Enterprise proves professional-level breadth, while CCIE Enterprise Infrastructure demands expert-level execution under pressure. The CCIE path expects deeper design tradeoff analysis, faster fault isolation, stronger integration knowledge across campus, WAN, overlays, and security, and hands-on performance in an 8-hour lab rather than a written-only path.
