Juniper Data Center, Professional (JNCIP-DC) 認定 JN0-683 試験問題 (Q30-Q35):

質問 # 30
You are preparing an sFlow monitoring system configuration.
In this scenario, what Information will be included in the datagram sent to the sFlow collector? (Choose two.)

A. the source and destination VLAN for sampled packets
B. the sending device's serial number
C. the interlace through which the packets entered the agent
D. the CRC from the sampled packet

正解：A、C

解説：
* Understanding sFlow Monitoring:
* sFlow is a packet sampling technology used to monitor traffic in a network. It sends sampled packet data and interface counters to an sFlow collector, which analyzes the traffic patterns.
* Information Included in sFlow Datagram:
* Option A:The datagram sent to the sFlow collector includes information about the interface through which the packets entered the agent (the switch or router). This is crucial for understanding where in the network the traffic was captured.
* Option D:sFlow datagrams also include the source and destination VLAN for the sampled packets. This allows for detailed analysis of the traffic flow within different VLANs.
Conclusion:
* Option A:Correct-The ingress interface is included in the sFlow datagram.
* Option D:Correct-The source and destination VLANs are also included, providing context for the sampled traffic.

質問 # 31
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?

A. Add encapsulation vxlan to the evpn hierarchy.
B. Change: 5001 in the route-distinguisher to : 10010.
C. Move vrf-target target: 65000:1 to the evpn hierarchy.
D. Add a VLAN configuration with an 13-interface to the tenant1 routing instance.

正解：C

解説：
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.

質問 # 32
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?

A. off-fabric using an external device
B. using EVPN Type 5 routes
C. using virtual gateway addresses configured on the spine
D. using anycast gateway addresses configured on the leaf devices

正解：A

解説：
* 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 References:
* 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.

質問 # 33
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 is less efficient than asymmetric routing.
C. An L3 interface (IRB) is required for each local VLAN.
D. Symmetric routing requires MAC-VRF.
E. Symmetric routing requires an extra transit VNI for each VRF.

正解：C、D、E

解説：
* 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.

質問 # 34
Exhibit.

Both DC and DC2 ate using EVPN-VXLAN technology deployed using an ERB architecture. A server on the Red VLAN must communicate with a server on the Green VLAN. The Blue VLAN in DC and DC2 needs to be the same VLAN.
Which statement is correct in this scenario?

A. The eight spine devices must be configured as border spine devices; a full mush interconnect must exist between all eight spine devices and the Blue VLAN must be stitched together
B. An interconnect is required between the four SRX Series devices; the Blue VLAN must be stretched and a transit VNI must be added for the Red and Green VLANs.
C. An interconnect is required between four leaf devices in the services blocks; the Red VLAN and the Green VLAN must be stitched and the Blue VLAN must be stretched.
D. A lean super spine device must be added to DC and DC2; all VLANs must be stretched to the lean super spine device and the lean super spine devices must stitch all the VLANs together.

正解：B

解説：
* ERB Architecture in EVPN-VXLAN:
* ERB (Edge Routed Bridging) architecture is commonly used in data center networks where routing decisions are made at the network edge (leaf or border devices), while bridging (Layer 2 forwarding) is extended across the fabric. This architecture allows for efficient L3 routing while still enabling L2 services like VLANs to span across multiple locations.
* VLAN and VNI Configuration:
* The scenario specifies that a server on the Red VLAN needs to communicate with a server on the Green VLAN. Since these VLANs are in different data centers (DC and DC2), and given the use of EVPN-VXLAN, the communication between these VLANs will require atransit VNI(Virtual Network Identifier). This transit VNI will allow traffic to traverse the VXLAN tunnel across the DCI (Data Center Interconnect).
* Interconnect between SRX Series Devices:
* The exhibit shows SRX Series Chassis Clusters used as service devices (likely for firewalling or other security services). These devices need to be interconnected between the two data centers to ensure that VLANs can communicate effectively. The Blue VLAN needs to be stretched between DC and DC2 to maintain the same Layer 2 domain across both data centers.
Conclusion:
* Option B:Correct-Interconnecting the SRX Series devices will ensure the necessary service chaining, while stretching the Blue VLAN and adding a transit VNI for the Red and Green VLANs will enable the required communication across the data centers.
