問題 #45
Exhibit.

You are troubleshooting an IP fabric (or your data center. You notice that your traffic is not being load balanced to your spine devices from your leaf devices. Referring to the configuration shown in the exhibit, what must be configured to solve this issue?

A. The multipast multiple -as configuration must be configured for each peer in the BGP spine group.
B. The load-balance policy must have a from statement that matches on protocol bgp.
C. The load-balance policy must be applied as an export policy to your BGP
D. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.

答案：D

解題說明：
Step 1: Understand the Configuration in the Exhibit
The exhibit provides three configuration snippets from a leaf device (user@leaf#):
* Policy Options:
user@leaf# show policy-options
policy-statement load-balance {
term 1 {
then {
load-balance per-packet;
}
}
}
* A policy named load-balance is defined, which applies the load-balance per-packet action. In Juniper terminology, per-packet actually means per-flow load balancing (a common point of confusion). This policy is intended to enable load balancing across multiple paths.
* Routing Options:
user@leaf# show routing-options
router-id 192.168.100.11;
autonomous-system 65100;
* The router ID is set to 192.168.100.11, and the autonomous system (AS) number is 65100. There' s no mention of applying the load-balance policy here, which is a clue to the issue.
* BGP Configuration:
user@leaf# show protocols
bgp {
group spine {
type external;
export direct;
local-as 65003;
multipath {
multiple-as;
}
neighbor 172.16.1.5 {
peer-as 65001;
}
neighbor 172.16.1.17 {
peer-as 65002;
}
}
}
* BGP is configured with an external group spine, where the leaf device (local AS 65003) peers with spine devices (AS 65001 and 65002).
* The multipath multiple-as statement is enabled, which allows BGP to install multiple paths for the same prefix in the routing table, even if the paths come from different AS numbers. This is a prerequisite for load balancing in a multi-AS environment like an IP fabric.
* The export direct policy is applied, which likely exports directly connected routes to the spine devices.
Step 2: Identify the Problem
The issue is that traffic from the leaf to the spine devices is not being load-balanced, despite the presence of a load-balance policy and BGP multipath. For load balancing to work in this scenario:
* BGP multipath ensures multiple paths are installed in the routing table.
* The load-balance per-packet policy is meant to distribute traffic across those paths.
* However, the load-balance policy is defined but not applied anywhere in the configuration shown. For load balancing to take effect, the policy must be applied in the correct context.
Step 3: Evaluate the Options
Let's go through each option to determine the correct solution:
* A. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.
* In Junos, to enable load balancing across multiple paths for forwarding, the load-balance policy must be applied at the forwarding table level. This is done under the routing-options hierarchy using the forwarding-table export statement. For example:
set routing-options forwarding-table export load-balance
* This ensures that the load-balancing policy is applied to the forwarding table, allowing traffic to be distributed across multiple equal-cost paths installed by BGP.
* B. The multipath multiple-as configuration must be configured for each peer in the BGP spine group.
* The multipath multiple-as statement is already configured under the spine group, and it applies to all neighbors in that group (172.16.1.5 and 172.16.1.17). There's no need to configure it per peer, as the group-level configuration is sufficient. This option is incorrect because the required setting is already in place.
* C. The load-balance policy must be applied as an export policy to your BGP.
* Applying the load-balance policy as a BGP export policy (e.g., export load-balance under the BGP group) would affect the routes advertised to the spine devices. However, the load-balance per-packet action is a forwarding action, not a route advertisement action. Applying it as a BGP export policy would not achieve the desired load balancing for traffic forwarding and is incorrect.
* D. The load-balance policy must have a from statement that matches on protocol bgp.
* The load-balance policy currently applies the load-balance per-packet action unconditionally (no from statement). Adding a from protocol bgp condition would make the policy apply only to BGP routes, but this is unnecessary in this context. The policy needs to be applied to the forwarding table to affect traffic, not modified with a from statement. This option doesn't address the core issue of applying the policy.
Step 4: Determine the Correct Answer
The key issue is that the load-balance policy is defined but not applied. For load balancing to work, it must be applied to the forwarding table under routing-options. This matchesOption A:
* A. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.
Step 5: Provide Official Juniper Documentation Reference
Since I don't have direct access to Juniper's proprietary documents, I can provide an explanation based on standard Junos documentation practices and publicly available resources, such as the Juniper TechLibrary, which is the official source for Junos configuration guides.
In Juniper's official documentation, specifically in theJunos OS Routing Protocols and Policies Configuration Guide, the process for enabling load balancing is described as follows:
* Load Balancing in Junos: To enable per-flow load balancing across multiple paths, you must define a policy with the load-balance per-packet action and apply it to the forwarding table. The relevant configuration hierarchy is:
routing-options {
forwarding-table {
export <policy-name>;
}
}
* Explanation from Documentation: The load-balance per-packet action (which performs per-flow balancing) requires the policy to be applied at the forwarding-table level to influence how traffic is distributed across multiple paths in the forwarding table. Without this, even if BGP installs multiple paths (via multipath), the forwarding engine will not load-balance traffic.
This aligns with the JNCIP-DC exam objectives, which include understanding how to configure and troubleshoot load balancing in an IP fabric, such as applying policies for traffic distribution.

問題 #46
You are designing an IP fabricfora 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. Use EX4300 Series devices as the spine devices.
C. Design a three-stage Clos IP fabric.
D. Design a five-stage Clos IP fabric.

答案：A,D

問題 #47
You want to provide a OCI that keeps each data center routing domain isolated, while also supporting translation of VNIs. Which DCI scheme allows these features?

A. MPLS DCI label exchange
B. over the top (OTT) with proxy gateways
C. over the top (OTT) with VNI translation enabled
D. VXLAN stitching

答案：D

解題說明：
* Understanding DCI (Data Center Interconnect) Schemes:
* DCI schemes are used to connect multiple data centers, enabling seamless communication and resource sharing between them. The choice of DCI depends on the specific requirements, such as isolation, VNI translation, or routing domain separation.
* VXLAN Stitching:
* VXLAN stitching involves connecting multiple VXLAN segments, allowing VNIs (VXLAN Network Identifiers) from different segments to communicate with each other while maintaining separate routing domains.
* This approach is particularly effective for keeping routing domains isolated while supporting VNI translation, making it ideal for scenarios where you need to connect different data centers or networks without merging their control planes.
* Other Options:
* A. MPLS DCI label exchange:This option typically focuses on MPLS-based interconnections and does not inherently support VNI translation or isolation in the context of VXLAN.
* B. Over the top (OTT) with VNI translation enabled:This could support VNI translation but does not inherently ensure routing domain isolation.
* D. Over the top (OTT) with proxy gateways:This typically involves using external gateways for traffic routing and may not directly support VNI translation or isolation in the same way as VXLAN stitching.
Data Center References:
* VXLAN stitching is a powerful method in multi-data center environments, allowing for flexibility in connecting various VXLAN segments while preserving network isolation and supporting complex interconnect requirements.

問題 #48
You are adding a server lo a tenant's network within your data center and must limit access to a specific traffic type within the tenant network without pushing all tenant traffic through a firewall.
What will satisfy this requirement?

A. Use filter-based forwarding.
B. Use route leaking with EVPN and a routing policy.
C. Put the new server on a unique subnet within the tenant's network.
D. Use a static route in the tenant VRF with a firewall as the next hop for traffic to the new server.

答案：A

解題說明：
* Controlling Traffic Within a Tenant's Network:
* The requirement is to limit access to specific traffic types within a tenant's network without routing all tenant traffic through a firewall. This requires a selective method that can direct specific types of traffic to different paths based on the nature of the traffic.
* Filter-Based Forwarding (FBF):
* FBF is a technique that allows for routing decisions based on filters applied to the traffic, such as matching on source IP addresses, destination IP addresses, or even specific application types (like HTTP or FTP). This allows specific types of traffic to be forwardedto a specific next hop (e.g., a firewall) without affecting the entire traffic flow within the tenant's network.
Conclusion:
* Option B:Correct-Filter-based forwarding allows for granular control of traffic, ensuring that only specific types of traffic within the tenant's network are redirected through a firewall, satisfying the requirement.

問題 #49
Exhibit.

Referring to the exhibit, why is the active source field blank for the entry that uses the 00:0c:29:e8:b7:39 MAC address?

A. The EVPN route for this host does not have a valid next hop.
B. The ARP lookup for this host has failed.
C. This entry is associated with a multicast EVPN route.
D. The host for this entry is locally connected to leaf1.

答案：D
