質問 # 29
You are deploying multiple Juniper switches al the same location. Your switches are currently using the factory-default configuration.
In this scenario, which two statements are correct? (Choose two.)

A. The DHCP server configuration cannot provide Junos version requirements to DHCP clients.
B. The switch will try to request an IP address from a DHCP server using all interfaces that are connected and are operational.
C. The switch will try to request an IP address from a DHCP server using only the management interface.
D. The DHCP server configuration can provide Junos version requirements to DHCP clients.

正解：B、D

解説：
* DHCP Behavior in Factory-Default Configuration:
* Option B:In the factory-default configuration, Juniper switches are designed to send DHCP requests on all operational interfaces. This behavior ensures that the switch can obtain an IP address for management and further configuration from any available DHCP server.
* Option D:The DHCP server can provide additional configuration parameters, including the required Junos version. This allows for automated provisioning and ensures that the switch is running the correct software version.
Conclusion:
* Option B:Correct-The switch will use any operational interface to request an IP address via DHCP.
* Option D:Correct-The DHCP server can specify Junos version requirements, enabling automated software management.

質問 # 30
Which two statements are correct about an IP fabric? (Choose two.)

A. All leaf devices can use the same AS number in an IP fabric without making any adjustments to the EBGP configuration
B. FBGP is only required to route mostrouting information to external devices outside the fabric.
C. Only a single point to point EBGP session is required between peers in an IP fabric.
D. The multipath multiple-as statement is required to enable ECMP if every device has a different AS number.

正解：A、D

解説：
* BGP in IP Fabric:
* In an IP fabric, Border Gateway Protocol (BGP) is used to manage the routing between leaf and spine devices. Each device can have the same or different Autonomous System (AS) numbers depending on the network design.
* Multipath Multiple-AS:
* Option B:If every device in the fabric has a different AS number, then enabling Equal-Cost Multi-Path (ECMP) routing requires the multipath multiple-as statement. This configuration allows BGP to consider multiple paths across different AS numbers as equal cost, enabling efficient load balancing across the network.
* Same AS Number Configuration:
* Option A:It's possible for all leaf devices to use the same AS number in an IP fabric, which simplifies the configuration. EBGP (External BGP) will still function correctly in this setup because BGP considers the peering relationship rather than strictly enforcing different AS numbers in this specific use case.
Conclusion:
* Option B:Correct-This statement is essential for enabling ECMP in a multi-AS environment.
* Option A:Correct-Leaf devices can share the same AS number without needing special EBGP configuration.

質問 # 31
Which statement is correct about a collapsed fabric EVPN-VXLAN architecture?

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

正解：A

解説：
* 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.

質問 # 32
Exhibit.

Referring to the exhibit, the spinel device has an underlay BGP group that is configured to peer with its neighbors' directly connected interfaces. Which two statements are true in this scenario? (Choose two.)

A. Load balancing for the underlay is not configured correctly.
B. Load balancing for the underlay is configured correctly.
C. The multihop statement is required to establish the underlay BGP sessions.
D. The multihop statement is not required to establish the underlay BGP sessions.

正解：B、D

解説：
* Understanding BGP Configuration in the Exhibit:
* The exhibit shows a BGP configuration on spine1 with a group named underlay, configured to peer with directly connected interfaces of other devices in the network.
* Multipath multiple-as:This statement allows the router to install multiple paths in the routing table for routes learned from different ASes, facilitating load balancing.
* Key Statements:
* A. The multihop statement is not required to establish the underlay BGP sessions:In this case, the BGP peers are directly connected (as indicated by their neighbor IP addresses), so the multihop statement is unnecessary. Multihop is typically used when BGP peers are not directly connected and packets need to traverse multiple hops.
* D. Load balancing for the underlay is configured correctly:The multipath { multiple-as; } statement in the configuration enables load balancing across multiple paths from different autonomous systems, which is appropriate for underlay networks in data center fabrics.
* Incorrect Statements:
* C. The multihop statement is required to establish the underlay BGP sessions:This is incorrect because the peers are directly connected, making the multihop statement unnecessary.
* B. Load balancing for the underlay is not configured correctly:This is incorrect because the configuration includes the necessary multipath settings for load balancing.
Data Center References:
* BGP configurations in EVPN-VXLAN underlay networks are crucial for ensuring redundancy, load balancing, and efficient route propagation across the data center fabric.

質問 # 33
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. over the top (OTT) with proxy gateways
B. MPLS DCI label exchange
C. over the top (OTT) with VNI translation enabled
D. VXLAN stitching

正解：D

解説：
* 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.
