NEW QUESTION # 51
In your EVPN-VXAN environment, you want to prevent a multihomed server from receiving multiple copies of BUM traffic in active/active scenarios. Which EVPN route type would satisfy this requirement?
Answer: D
Explanation:
In an EVPN-VXLAN environment with active-active multihoming, a multihomed server connected to multiple leaf switches can receive duplicate copies of BUM (Broadcast, Unknown Unicast, and Multicast) traffic. To prevent this, Type 4 (Ethernet Segment Route) is used.
EVPN Type 4 routes are responsible for DF (Designated Forwarder) election, which ensures that only one leaf switch forwards BUM traffic to the multihomed server. This prevents duplicate frames and optimizes network efficiency.
NEW QUESTION # 52
You are deploying an IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)
Answer: A,C
Explanation:
* Understanding Oversubscription Ratio in IP Fabrics:
* The oversubscription ratio in an IP fabric typically refers to the ratio of the available bandwidth at the edge of the network (leaves) to the available bandwidth at the core or spine. A 3:1 oversubscription ratio means that for every 3 units of bandwidth at the leaves, there is 1 unit of bandwidth at the spine.
* Impact of Adding or Removing Leaf Devices:
* Removing Leaf Devices:When you remove leaf devices, the amount of total edge bandwidth decreases while the bandwidth in the spine remains constant. This causes the oversubscription ratio toincreasebecause there is now less total bandwidth to distribute across the same amount of spine bandwidth.
* Adding Leaf Devices:Conversely, when you add leaf devices, the total edge bandwidth increases. Since the spine bandwidth remains the same, the oversubscription ratio would remain the same if the additional leaves consume their share of the available bandwidth proportionally.
Conclusion:
* Option C:Correct-Removing leaf devices increases the oversubscription ratio.
* Option D:Correct-Adding leaf devices typically maintains the oversubscription ratio assuming uniform bandwidth distribution.
NEW QUESTION # 53
Exhibit.
You want to enable the border leaf device to send Type 5 routes of local networks to the border leaf device in another data center. What must be changed to the configuration shown in the exhibit to satisfy this requirement?
Answer: D
Explanation:
In this scenario, you want the border leaf device to advertise Type 5 EVPN routes to another border leaf in a different data center. Type 5 routes in EVPN are used to advertise IP prefixes, which means that for proper route advertisement, you need to configure the correct settings within the evpn hierarchy.
Step-by-Step Analysis:
* Understanding EVPN Type 5 Routes:
* EVPN Type 5 routes are used to advertise IP prefixes across EVPN instances, which allow different data centers or networks to exchange routing information effectively.
* VRF Target Setting:
* The vrf-target configuration is crucial because it defines the export and import policies for the VRF within the EVPN instance. For EVPN Type 5 routes to be advertised to other border leaf devices, the vrf-target needs to be correctly configured under the evpn hierarchy, not just within the routing instance.
Command to solve this:
move vrf-target target:65000:1 to evpn
* Other Options:
* Option B:Adding a VLAN configuration would not address the requirement to advertise Type 5 routes.
* Option C:Adding VXLAN encapsulation may be necessary for other scenarios but does not directly address the Type 5 route advertisement.
* Option D:Changing the route-distinguisher will differentiate routes but does not impact the advertisement of Type 5 routes to other data centers.
By moving the vrf-target to the evpn hierarchy, you enable the proper route advertisement, ensuring that the Type 5 routes for local networks are shared with other data center border leaf devices. This is aligned with best practices for multi-data center EVPN implementations, which emphasize the correct placement of routing policies within the EVPN configuration.
NEW QUESTION # 54
Exhibit.
You are troubleshooting a DCI connection to another data center The BGP session to the provider is established, but the session to Border-Leaf-2 is not established. Referring to the exhibit, which configuration change should be made to solve the problem?
Answer: A
Explanation:
* Understanding the Configuration:
* The exhibit shows a BGP configuration on a Border-Leaf device. The BGP group UNDERLAY is used for the underlay network, OVERLAY for EVPN signaling, and PROVIDER for connecting to the provider network.
* The OVERLAY group has the accept-remote-nexthop statement, which is designed to accept the next-hop address learned from the remote peer as is, without modifying it.
* Problem Identification:
* The BGP session to Border-Leaf-2 is not established. A common issue in EVPN-VXLAN environments is related to next-hop reachability, especially when accept-remote-nexthop is configured.
* In typical EVPN-VXLAN setups, the next-hop address should be reachable within the overlay network. However, the accept-remote-nexthop can cause issues if the next-hop IP address is not directly reachable or conflicts with the expected behavior in the overlay.
* Corrective Action:
* D. delete protocols bgp group OVERLAY accept-remote-nexthop:Removing this command will ensure that the device uses its own IP address as the next-hop in BGP advertisements, which is standard practice in many EVPN-VXLAN setups. This change should help establish the BGP session with Border-Leaf-2.
Data Center References:
* Proper handling of BGP next-hop attributes is critical in establishing and maintaining stable BGP sessions, especially in complex multi-fabric environments like EVPN-VXLAN. Removing accept- remote-nexthop aligns with best practices in many scenarios.
NEW QUESTION # 55
Exhibit.
Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.
Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)
Answer: B,D
Explanation:
* Review of the Exhibit:
* The exhibit shows the switch configuration for Leaf-1 and Leaf-2. The configurations include route distinguishers, VRF targets, and service IDs, all of which are crucial for ensuring proper operation in an EVPN-VXLAN environment.
* Service-ID Consistency:
* The service ID must be consistent across all participating leaf devices in the same EVPN instance to ensure that they are part of the same VXLAN overlay network.
* VRF Target Consistency:
* The vrf-target parameter must also be consistent across devices to ensure that VRFs (Virtual Routing and Forwarding instances) are correctly imported and exported between leaf nodes.
Conclusion:
* Option B:Correct-Setting the same service-id on Leaf-2 ensures that it is part of the same VXLAN overlay as Leaf-1.
* Option D:Correct-The vrf-target on Leaf-2 should match Leaf-1 to ensure consistent routing policies and proper route exchange.
