Juniper Data Center, Professional (JNCIP-DC) 認定 JN0-683 試験問題 (Q45-Q50):

質問 # 45
You are asked for TX and RX traffic statistics for each interface to which an application server is attached.
The statistics need to be reported every five seconds. Using the Junos default settings, which telemetry method would accomplish this request?

A. OpenConfig
B. gNMI
C. SNMP
D. Native Sensors

正解：D

解説：
* Telemetry Methods in Junos:
* Telemetry is used to collect and report data from network devices. For high-frequency statistics reporting, such as every five seconds, you need a telemetry method that supports this level of granularity and real-time monitoring.
* Junos Native Sensors:
* Option C:Native Sensors in Junos provide detailed, high-frequency telemetry data, including TX and RX traffic statistics for interfaces. They are designed to offer real-time monitoring with customizable sampling intervals, making them ideal for the five-second reporting requirement.
Conclusion:
* Option C:Correct-Native Sensors in Junos are capable of providing the required high-frequency telemetry data every five seconds.

質問 # 46
You are deploying a new network lo support your Al workloads on devices that support at least 400 Gbps Ethernet. There is no requirement for any Layer 2 VLANs in this network. Which network architecture would satisfy this requirement?

A. an IP fabric using EBGP
B. an IP fabric using PIM-SM to signal VXLAN overlay
C. an IP fabric using the EVPN-MPLS architecture
D. an IP fabric with an EVPN-VXLAN architecture

正解：A

解説：
* Requirements for AI Workloads:
* The scenario requires a network that supports at least 400 Gbps Ethernet and does not require Layer 2 VLANs. This setup is well-suited for a pure Layer 3 network, which can efficiently route traffic between devices without the overhead or complexity of maintaining Layer 2 domains.
* Choosing the Right Network Architecture:
* Option D:An IP fabric using EBGP (External BGP) is ideal for this scenario. In a typical IP fabric, EBGP is used to handle routing between spine and leaf switches, creating a scalable and efficient network. Since there is no need for Layer 2 VLANs, the pure IP fabric design with EBGP provides a straightforward and effective solution.
* Options A, B, and Cinvolve more complex architectures (like VXLAN or EVPN), which are unnecessary when there's no requirement for Layer 2 overlays or VLANs.
Conclusion:
* Option D:Correct-An IP fabric with EBGP is the most suitable and straightforward architecture for a network that needs to support high-speed AI workloads without Layer 2 VLANs.

質問 # 47
Exhibit.

Referring to the exhibit, which statement Is true?

A. An ERB architecture is being used.
B. A CRB architecture is being used.
C. A PBB-EVPN architecture is being used.
D. An OTT architecture is being used.

正解：A

解説：
* Understanding Network Architectures:
* ERB (Edge Routed Bridging) architecture involves routing at the network's edge (leaf nodes), while traffic between leaf nodes is switched. This is commonly used in VXLAN-EVPN setups.
* Analysis of the Exhibit:
* The exhibit shows configurations related to routing instances, VXLAN, and VLANs, with VNIs being used for each VLAN. This setup is characteristic of an ERB architecture where each leaf device handles Layer 3 routing for its connected devices.
Conclusion:
* Option B:Correct-The configuration shown corresponds to an ERB architecture where routing occurs at the network's edge (leaf devices).

質問 # 48
You are asked to identify microburst traffic occurring in the network leading lo packet drops in your data center switches Which two tools would be used in this scenario? (Choose two.)

A. Traceoptions
B. port mirroring
C. port buffer monitoring
D. syslog

正解：B、C

解説：
* Identifying Microburst Traffic:
* Microbursts are short spikes in network traffic that can overwhelm buffers and cause packet drops. Detecting and analyzing microbursts is crucial for understanding where packet loss might be occurring in a data center network.
* Port Buffer Monitoring:
* Port Buffer Monitoring:This tool specifically tracks the usage of switch buffers, helping to identify when microbursts are causing buffers to overflow, leading to packet drops.
* Port Mirroring:
* Port Mirroring:This tool allows you to monitor real-time traffic on a specific port by copying the traffic to another port where it can be analyzed, often with a packet analyzer. While port mirroring doesn't directly detect microbursts, it helps capture traffic patterns that can indicate microbursts.
Conclusion:
* Option C:Correct-Port buffer monitoring directly identifies buffer overflows caused by microbursts.
* Option A:Correct-Port mirroring allows for the detailed capture and analysis of traffic patterns, which can reveal microburst behavior.
Options B(Traceoptions) andD(Syslog) are less effective in identifying microburst traffic. Traceoptions focus on control plane traffic debugging, and Syslog is more about logging system events than detecting high- frequency traffic spikes.

質問 # 49
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. delete vlans vn200 13-interface irb.200
B. set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
C. set interfaces irb unit 100 family inet address 192-168.100.1
D. set vlans vn10013-interface irb.100

正解：B、D

解説：
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.
