You are asked to deploy 100 QFX Series devices using ZTP Each OFX5120 requires a different configuration. In this scenario, what are two components that you would configure on the DHCP server? (Choose two.)
Zero Touch Provisioning (ZTP):
ZTP allows for the automated configuration of network devices, like QFX Series switches, without manual intervention. During ZTP, a switch will obtain its configuration from a DHCP server and then download the required software and configuration files from a specified server (e.g., FTP, HTTP).
DHCP Server Configuration:
Option B: The DHCP server needs to know the MAC address for each QFX5120 to provide a specific configuration based on the device identity. By mapping the MAC address to a particular configuration, the DHCP server can ensure that each switch gets the correct configuration.
Option D: The management IP address for each QFX5120 must also be assigned by the DHCP server. This IP address allows the device to communicate on the network and access the configuration files and other required resources during the ZTP process.
Conclusion:
Option B: Correct---MAC addresses allow the DHCP server to identify each QFX5120 and assign the appropriate configuration.
Option D: Correct---Management IP addresses are essential for network communication during ZTP.
Exhibit.
A VXLAN tunnel has been created between leaf1 and Ieaf2 in your data center. Referring to the exhibit, which statement is correct?
Understanding VXLAN Tunneling:
VXLAN (Virtual Extensible LAN) is a network virtualization technology that addresses the scalability issues associated with traditional VLANs. VXLAN encapsulates Ethernet frames in UDP, allowing Layer 2 connectivity to extend across Layer 3 networks.
Each VXLAN network is identified by a unique VXLAN Network Identifier (VNI). In this exhibit, we have two VNIs, 5100 and 5200, assigned to the VXLAN tunnels between leaf1 and leaf2.
Network Setup Details:
Leaf1: Connected to Server1 with VLAN ID 100 and associated with VNI 5100.
Leaf2: Connected to Server2 with VLAN ID 200 and associated with VNI 5200.
Spine: Acts as the interconnect between leaf switches.
Traffic Flow Analysis:
When traffic is sent from Server1 to Server2, it is initially tagged with VLAN ID 100 on leaf1.
The traffic is encapsulated into a VXLAN packet with VNI 5100 on leaf1.
The packet is then sent across the network (via the spine) to leaf2.
On leaf2, the VXLAN header is removed, and the original Ethernet frame is decapsulated.
Leaf2 will then associate this traffic with VLAN ID 200 before forwarding it to Server2.
Correct Interpretation of the Exhibit:
The traffic originating from Server1, which is tagged with VLAN ID 100, will be encapsulated into VXLAN and transmitted to leaf2.
Upon arrival at leaf2, it will be decapsulated, and since it is associated with VNI 5200 on leaf2, the traffic will be retagged with VLAN ID 200.
Therefore, the traffic will reach Server2 tagged with VLAN ID 200, which matches the network configuration shown in the exhibit.
Data Center Reference:
This configuration is typical in data centers using VXLAN for network virtualization. It allows isolated Layer 2 segments (VLANs) to be stretched across Layer 3 boundaries while maintaining distinct VLAN IDs at each site.
This approach is efficient for scaling large data center networks while avoiding VLAN ID exhaustion and enabling easier segmentation.
In summary, the correct behavior, as per the exhibit and the detailed explanation, is that traffic sent from Server1 will be tagged with VLAN ID 200 when it reaches Server2 via leaf2. This ensures proper traffic segmentation and handling across the VXLAN-enabled data center network.
Exhibit.
Referring to the configuration shown in the exhibit, assume that there is no external router present, and that the configuration is fabric-only.
Which two statements are true about the example configuration? (Choose two.)
Understanding the Configuration:
The exhibit shows configurations for two VRFs (Customer_A and Customer_B) with specific VLANs and VNIs assigned. Each VRF has interfaces (IRBs) associated with particular VLANs.
Communication Between VLANs and Routing Instances:
Option B: VLAN 400 (irb.400) is part of Customer_B, and there is no direct connection or routing between Customer_A and Customer_B in the configuration provided. Therefore, devices in irb.400 cannot communicate directly with devices in the Customer_A routing instance.
Option D: Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.
Conclusion:
Option B: Correct---There is no direct communication between devices in irb.400 (Customer_B) and routing instance Customer_A.
Option D: Correct---Devices in VLAN 400 and VLAN 800 can communicate within the Customer_B routing instance over the fabric.
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?
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 forwarded to 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.
You are using a single tenant data center with a bridged overlay architecture. In this scenario, how do hosts of the different virtual networks communicate with each other?
Understanding Bridged Overlay Architecture:
In a single-tenant data center using a bridged overlay architecture, virtual networks (VLANs) are typically isolated within the fabric, with traffic between these VLANs handled outside the fabric.
Communication Between Different Virtual Networks:
A . off-fabric using an external device: This is correct. In many bridged overlay architectures, communication between different virtual networks is handled off-fabric, often using an external router or firewall that connects the different VLANs. The fabric itself primarily provides Layer 2 connectivity within each VLAN, leaving inter-VLAN routing to be handled externally.
Data Center Reference:
This design is common in smaller or simpler data center environments where a single tenant does not require complex on-fabric routing and prefers to handle inter-VLAN routing through dedicated devices.
