Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q66-Q71):

NEW QUESTION # 66
Your organization is implementing EVPN-VXLAN and requires multiple overlapping VLAN-IDs. You decide to use a routing-instance type mac-vrf to satisfy this request.
Which two statements are correct in this scenario? (Choose two.)

A. The routing-instance service type can be VLAN-based.
B. Host-facing interfaces must be configured using a service-provider style configuration.
C. Host-facing interfaces must be configured using enterprise-style configuration.
D. Spine-facing interfaces must be configured using an enterprise-styleconfiguration.

Answer: A,B

Explanation:
* Understanding the Scenario:
* EVPN-VXLAN deployments often involve scenarios where multiple tenants or applications require overlapping VLAN IDs, which can be managed using the mac-vrf routing instance type.
This allows you to segregate traffic within the same VLAN ID across different tenants.
* Host-facing Interface Configuration:
* A. Host-facing interfaces must be configured using a service-provider style configuration:
This is correct. In mac-vrf configurations, host-facing interfaces (those connecting end devices) typically follow a service-provider style configuration, where each customer or tenant's traffic is isolated even if overlapping VLAN IDs are used.
* B. Host-facing interfaces must be configured using enterprise-style configuration:This is incorrect for mac-vrf instances because enterprise-style configurations are more common in simpler, less segmented networks.
* Routing Instance Service Type:
* D. The routing-instance service type can be VLAN-based:This is correct. The service type in mac-vrf can indeed be VLAN-based, which is particularly useful in scenarios where VLAN ID overlap is needed between different tenants or services.
Data Center References:
* The mac-vrf instance type is powerful for handling complex multi-tenant environments in EVPN- VXLAN, especially when dealing with overlapping VLAN IDs across different segments of the network.

NEW QUESTION # 67
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 multipastmultiple -as configuration must be configured for each peer in the BGP spine group.
B. The load-balance policy must be applied as an export policy to your BGP
C. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.
D. The load-balance policy must have a from statement that matches on protocol bgp.

Answer: A

Explanation:
* IP Fabric Load Balancing:
* In the provided configuration, traffic is not being load-balanced to the spine devices. The issue likely relates to how BGP routes are being selected and whether Equal-Cost Multi-Path (ECMP) is functioning correctly.
* Multipath Multiple-AS:
* Option B:The multipath multiple-as configuration is essential when using BGP in an IP fabric where devices belong to different Autonomous Systems (AS). This setting allows BGP to consider multiple paths (even across different AS numbers) as equal cost, enabling ECMP and proper load balancing across spine devices.
Conclusion:
* Option B:Correct-The multipath multiple-as configuration is necessary for achieving ECMP and effective load balancing in a multi-AS BGP environment.

NEW QUESTION # 68
Exhibit.

Given the configuration shown in the exhibit, why has the next hop remained the same for the EVPN routes advertised to the peer 203.0.113.2?

A. The vpn-apply-export parameter must be applied to this peer.
B. EVPN routes cannot have the next hop changed.
C. The vrf-export parameter must be applied.
D. The export policy is incorrectly configured.

Answer: A

Explanation:
* Understanding the Configuration:
* The configuration shown in the exhibit involves an EVPN (Ethernet VPN) setup using BGP as the routing protocol. The export policy named CHANGE_NH is applied to the BGP group evpn- peer, which includes a rule to change the next hop for routes that match the policy.
* Issue with Next Hop Not Changing:
* The policy CHANGE_NH is correctly configured to change the next hop to 203.0.113.10 for the matching routes. However, the next hop remains unchanged when advertising EVPN routes to the peer 203.0.113.2.
* Reason for the Issue:
* In Junos OS, when exporting routes for VPNs (including EVPN), the next-hop change defined in a policy will not take effect unless the vpn-apply-export parameter is used inthe BGP configuration. This parameter ensures that the export policy is applied specifically to VPN routes.
* The vpn-apply-export parameter must be included to apply the next-hop change to EVPN routes.
* Correct Answer Explanation:
* D. The vpn-apply-export parameter must be applied to this peer:This is the correct solution because the next hop in EVPN routes won't be altered without this parameter in the BGP configuration. It instructs the BGP process to apply the export policy to the EVPN routes.
Data Center References:
* This behavior is standard in EVPN deployments with Juniper Networks devices, where the export policies applied to VPN routes require explicit invocation using vpn-apply-export to take effect.

NEW QUESTION # 69
Which statement is correct about a collapsed fabric EVPN-VXLAN architecture?

A. Using Virtual Chassis at the leaf layer increases resiliency.
B. It supports multiple vendors in the fabric as long as all the spine devices are Juniper devices deployed with L2 VTEPs
C. Border gateway functions occur on border leaf devices.
D. Fully meshed back-to-back links are needed between the spine devices.

Answer: C

Explanation:
* Collapsed Fabric Architecture:
* A collapsed fabric refers to a simplified architecture where the spine and leaf roles are combined, often reducing the number of devices and links required.
* In this architecture, the spine typically handles core switching, while leaf switches handle both access and distribution roles.
* Understanding Border Gateway Functionality:
* Border gateway functions include connecting the data center to external networks or other data centers.
* In a collapsed fabric, these functions are usually handled at the leaf level, particularly on border leaf devices that manage the ingress and egress of traffic to and from the data center fabric.
* Correct Statement:
* D. Border gateway functions occur on border leaf devices:This is accurate in collapsed fabric architectures, where the border leaf devices take on the role of managing external connections and handling routes to other data centers or the internet.
Data Center References:
* The collapsed fabric model is advantageous in smaller deployments or scenarios where simplicity and cost-effectiveness are prioritized. It reduces complexity by consolidating functions into fewer devices, and the border leaf handles the critical task of interfacing with external networks.
In conclusion, border gateway functions are effectively managed at the leaf layer in collapsed fabric architectures, ensuring that the data center can communicate with external networks seamlessly.

NEW QUESTION # 70
Exhibit.

Host A is connected to vlan 100 on lead. Host B is connected to vlan 200 on leaf1. Host A and Host B ate unable to communicate. You have reviewed the touting and your hosts have the correct default route (.1) Referring to the exhibit, which two commands will solve the problem? (Choose two.)

A. set interfaces irb unit 100 family inet address 192-168.100.1
B. set vlans vn10013-interface irb.100
C. set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
D. delete vlans vn200 13-interface irb.200

Answer: B,C

Explanation:
In the provided network configuration, Host A is in VLAN 100 and Host B is in VLAN 200. The issue arises because these two hosts are unable to communicate, which indicates that either the interfaces are not properly linked to their respective VLANs, or there is a missing static route required for inter-VLAN routing.
Step-by-Step Analysis:
* VLAN Assignment:
* The exhibit shows that irb.200 is correctly associated with VLAN 200 in the configuration.
However, there is no corresponding irb.100 for VLAN 100. Without irb.100, the network lacks the logical interface to handle routing for VLAN 100. Thus, adding irb.100 to VLAN 100 is necessary.
Command to solve this:
set vlans vn100 13-interface irb.100
* Static Route Configuration:
* For inter-VLAN routing to occur, a static route needs to be configured that allows traffic to pass between different subnets (in this case, between VLAN 100 and VLAN 200). The command set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10 would add a static route that directs all traffic from VLAN 100 to the correct gateway (192.168.200.10), which is necessary to route traffic between the two VLANs.
Command to solve this:
set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
Explanation of Incorrect Options:
* Option A (delete vlans vn200 13-interface irb.200): This would remove the logical interface associated with VLAN 200, which is not desired because we need VLAN 200 to remain active and properly routed.
* Option B (set interfaces irb unit 100 family inet address 192-168.100.1): This command would incorrectly assign an IP address that does not correspond with the subnet of VLAN 100 (192.168.200.1
/24). This could create a misconfiguration, leading to routing issues.
Data Center References:
For a Data Center, proper VLAN management and static routing are crucial for ensuring that different network segments can communicate effectively, especially when dealing with separated subnets or zones like in different VLANs. This aligns with best practices in DCIM (Data Center InfrastructureManagement) which stress the importance of proper network configuration to avoid downtime and ensure seamless communication between all critical IT infrastructure components.
Ensuring that the correct interfaces are associated with the correct VLANs and having the proper static routes in place are both essential steps in maintaining a robust and reliable data center network.
This detailed analysis reflects best practices as noted in standard data center design and network configuration guides.
