If you don't have an electronic product around you, or you don't have a network, you can use a printed PDF version of our 400-007 training materials. We also strongly recommend that you print a copy of the PDF version of your 400-007 study materials in advance so that you can use it as you like. And you can also take notes on the printale 400-007 Exam Questions whenever you had a better understanding. Of course, which kind of equipment to choose to study will ultimately depend on your own preference.
Cisco 400-007 exam is a certification exam for network designers who wish to validate their skills and knowledge in designing complex and large-scale networks. It is also known as the Cisco Certified Design Expert (CCDE v3.0) Written exam. 400-007 Exam is designed to test the candidate's skills in designing, analyzing, and optimizing complex network infrastructures.
NEW QUESTION # 422
Refer to the exhibit. The network experiences Stuck-in-Active (SIA) problems due to resource contention. An acquisition will further increase routing demands via R3 and R4.
Which solution best mitigates the SIA issue?
Answer: C
Explanation:
# Explanation:
C: Configuring R5 and R6 as EIGRP stub routers reduces query scope and prevents SIA conditions. EIGRP stub routers do not forward queries and are ideal for spoke or edge routers.
Other options:
A: Load balancing doesn't reduce control-plane query overhead.
B: Route Flap Dampening isn't applicable to EIGRP and won't solve SIA.
D: Default route advertisement helps simplify routing, but stub configuration is purpose-built to prevent SIA issues.

NEW QUESTION # 423
Which two features are advantages of SD-WAN compared to MPLS-based connectivity? (Choose two.)
Answer: B,D
NEW QUESTION # 424
The Layer 3 control plane is the intelligence over the network that steers traffic toward its intended destination. Which two techniques can be used in service provider-style networks to offer a more dynamic, flexible, controlled, and secure control plane design? (Choose two.)
Answer: C,E
NEW QUESTION # 425
The SD-WAN architecture is composed of separate orchestration, management, control, and data planes.
Which activity happens at the orchestration plane?
Answer: C
Explanation:
The SD-WAN architecture separates roles by function:
* Orchestration Plane: Handles device lifecycle functions such as zero-touch provisioning (ZTP) and certificate distribution. It facilitates onboarding into the overlay securely and automatically.
* Control Plane: Makes forwarding decisions and shares route and policy information.
* Data Plane: Forwards packets.
* Management Plane: Provides visibility, analytics, and template-based policy configuration.
Option A correctly identifies orchestration as the ZTP and bootstrapping component.
NEW QUESTION # 426
As part of a new network design documentation, you are required to explain the reason for choosing Cisco FabricPath for Layer 2 loop avoidance.
Which two elements help Cisco FabricPath mitigate Layer 2 loops if they happen in the Layer 2 MP network?
(Choose two)
Answer: B,C
Explanation:
Cisco FabricPath is a Layer 2 multipath technology that blends traditional Layer 2 Ethernet with routing technologies to enable loop-free forwarding and scalability. Two critical mechanisms used to mitigate loops:
* C. RPF (Reverse Path Forwarding) Check: FabricPath applies a reverse path forwarding check, similar to multicast, to verify the source of a frame and discard duplicates arriving on unexpected paths.
* D. TTL Header: FabricPath adds a Time-To-Live (TTL) field to Layer 2 frames, which is not present in traditional Ethernet. This prevents indefinite circulation of frames by limiting their lifetime in the network-much like in IP.
These elements allow FabricPath to prevent broadcast storms and loops in multipath Layer 2 topologies, addressing legacy STP limitations with efficient loop-avoidance methods.
