Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q37-Q42):

NEW QUESTION # 37
You are using E8GP peering in an underlay IP fabric. Which two statements are correct in this scenario?
(Choose two.)

  • A. Every leaf node has one peering session to every spine node.
  • B. EBGP peering requires an IGP protocol tor adjacency establishment.
  • C. Every leaf node has a peering session to every other leaf node.
  • D. EBGP peering does not require an IGP protocol tor adjacency establishment.

Answer: A,D

Explanation:
* Understanding EBGP in an IP Fabric:
* EBGP (External Border Gateway Protocol) is commonly used in IP fabrics to establish peering between routers, such as leaf and spine nodes, without relying on an Interior Gateway Protocol (IGP) like OSPF or IS-IS.
* IGP Requirement for EBGP:
* Option B:EBGP peering does not require an IGP for adjacency establishment. This is because EBGP peers are typically directly connected, and BGP establishes its own sessions without needing an underlying IGP.
* Leaf-to-Spine Peering:
* Option C:In a typical IP fabric, each leaf node establishes an EBGP session with every spine node. This ensures full connectivity between leaves and spines, facilitating efficient routing and forwarding within the fabric.
Conclusion:
* Option B:Correct-EBGP does not require an IGP for establishing peering sessions.
* Option C:Correct-Each leaf node peers with every spine node, which is a standard practice in IP fabrics to ensure connectivity and redundancy.


NEW QUESTION # 38
Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

  • A. Symmetric routing supports the EVPN service VLAN bundle.
  • B. Symmetric routing requires MAC-VRF.
  • C. An L3 interface (IRB) is required for each local VLAN.
  • D. Symmetric routing requires an extra transit VNI for each VRF.
  • E. Symmetric routing is less efficient than asymmetric routing.

Answer: B,C,D

Explanation:
* Symmetric IRB Routing with EVPN Type 2 Routes:
* Symmetric Routing: In symmetric IRB (Integrated Routing and Bridging), routing occurs in both directions at the ingress and egress leaf nodes using the same routing logic. This is contrasted with asymmetric routing, where different routing logic is used depending on the direction of the traffic.
* Required Components:
* Option A:An L3 IRB interface is necessary for each VLAN that participates in routing, as it handles the Layer 3 processing for the VLAN.
* Option B:MAC-VRF is required for symmetric routing to maintain a mapping of MAC addresses to the appropriate VRF, ensuring correct forwarding within the EVPN.
* Option D:A transit VNI (Virtual Network Identifier) is required for each VRF to encapsulate the Layer 3 traffic as it traverses the network, allowing the IP traffic to be appropriately forwarded.
Conclusion:
* Option A:Correct-Each local VLAN needs an IRB interface for L3 processing.
* Option B:Correct-MAC-VRF is necessary for handling MAC address resolution in symmetric routing.
* Option D:Correct-Transit VNIs are required for routing VRF-specific traffic across the network.
OptionsCandEare incorrect because:
* C:Symmetric routing can work with various VLAN models, including single or multiple VLANs within an EVPN instance.
* E:Symmetric routing is generally more efficient than asymmetric routing as it uses consistent routing logic in both directions.


NEW QUESTION # 39
Which two statements are true about a pure IP fabric? (Choose two.)

  • A. Devices in an IP fabric function as Layer 3 routers.
  • B. An IP fabric does not support Layer 2 protocols.
  • C. Devices in an IP fabric must be connected to a fabric controller.
  • D. An IP fabric supports Layer 2 VLANs.

Answer: A,B

Explanation:
* Understanding Pure IP Fabric:
* A pure IP fabric is a network design where all devices operate at Layer 3, meaning that each device in the fabric is a router that makes forwarding decisions based on IP addresses.
* Layer 2 Support:
* In a pure IP fabric, traditional Layer 2 protocols such as Spanning Tree Protocol (STP) or VLANs are not supported. Instead, the network relies entirely on Layer 3 routing protocols to manage traffic between devices.
* Routing Functionality:
* Since devices in an IP fabric operate as Layer 3 routers, they handle IP routing and provide network services based on IP addresses, not on MAC addresses or Layer 2 switching.
Conclusion:
* Option A:Correct-Devices in an IP fabric function as Layer 3 routers.
* Option D:Correct-A pure IP fabric does not support traditional Layer 2 protocols, making it a purely routed environment.


NEW QUESTION # 40
Which two statements are true about IP fabrics using unnumbered BGP? (Choose two.)

  • A. Unnumbered BGP peering automatically provisions IPv6 peering.
  • B. Unnumbered BGP requires that family inet6is configured on each interface.
  • C. Unnumbered BGP peering automatically provisions IPv4 peering.
  • D. Unnumbered BGP requires that family inet is configured on each interface.

Answer: C,D

Explanation:
* Understanding Unnumbered BGP:
* Unnumbered BGP (Border Gateway Protocol) allows BGP peering between routers without assigning specific IP addresses to the interfaces. Instead, it uses the loopback address or another router identifier for the BGP session, making IP address management more straightforward in large-scale networks.
* Family inet Configuration:
* Option C:The family inet configuration is required on each interface involved in unnumbered BGP peering to support IPv4 address families. This ensures that IPv4 peering sessions can be established between devices.
* Automatic IPv4 Peering:
* Option D:Unnumbered BGP peering automatically provisions IPv4 peering sessions. This simplifies the configuration by eliminating the need to manually assign and manage IP addresses for BGP peering.
Conclusion:
* Option C:Correct-Unnumbered BGP requires the family inet configuration for IPv4.
* Option D:Correct-Unnumbered BGP automatically provisions IPv4 peering, simplifying setup.


NEW QUESTION # 41
You are designing an IP fabric tor a large data center, and you are concerned about growth and scalability.
Which two actions would you take to address these concerns? (Choose two.)

  • A. Use OFX5700 Series devices as the super spines.
  • B. Design a five-stage Clos IP fabric.
  • C. Design a three-stage Clos IP fabric.
  • D. Use EX4300 Series devices as the spine devices.

Answer: A,C

Explanation:
* Clos IP Fabric Design:
* A Clos fabric is a network topology designed for scalable, high-performance data centers. It is typically arranged in multiple stages, providing redundancy, high bandwidth, and low latency.
* Three-Stage Clos Fabric:
* Option B:A three-stage Clos fabric, consisting of leaf, spine, and super spine layers, is widely used in data centers. This design scales well and allows for easy expansion by adding more leaf and spine devices as needed.
* Super Spines for Scalability:
* Option D:Using high-capacity devices like the QFX5700 Series as super spines can handle the increased traffic demands in large data centers and support future growth. These devices provide the necessary bandwidth and scalability for large-scale deployments.
Conclusion:
* Option B:Correct-A three-stage Clos fabric is a proven design that addresses growth and scalability concerns in large data centers.
* Option D:Correct-QFX5700 Series devices are suitable for use as super spines in large-scale environments due to their high performance.
