質問 # 17
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.)
正解：A、B
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.
質問 # 18
What are three actions available for MAC move limiting? (Choose three.)
正解：B、C、E
解説：
MAC move limiting is a security feature used in network switches to detect and mitigate rapid changes in MAC address locations, which could indicate a network issue or an attack such as MAC flapping or spoofing.
When a MAC address is learned on a different interface than it was previously learned, the switch can take various actions to prevent potential issues.
drop: This action drops packets from the MAC address if it violates the move limit, effectively blocking communication from the offending MAC address.
log: This action logs the MAC move event without disrupting traffic, allowing network administrators to monitor and investigate the event.
shutdown: This action shuts down the interface on which the MAC address violation occurred, effectively stopping all traffic on that interface to prevent further issues.
質問 # 19
You are deploying a Clos IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)
正解：A、B
解説：
* Understanding Oversubscription in a Clos Fabric:
* The oversubscription ratio in a Clos IP fabric measures the ratio of the amount of edge (leaf) bandwidth to the core (spine) bandwidth. An oversubscription ratio of 3:1 means that there is three times more edge bandwidth compared to core bandwidth.
* Impact of Adding/Removing Spine Devices:
* Option C:If youremove spine devices, the total available core bandwidth decreases, while the edge bandwidth remains the same. This results in anincrease in the oversubscription ratio because there is now less core bandwidth to handle the same amount of edge traffic.
* Option B:Conversely, if youadd spine devices, the total core bandwidth increases. This decreases the oversubscription ratio because more core bandwidth is available to handle the edge traffic.
Conclusion:
* Option C:Correct-Removing spine devices increases the oversubscription ratio.
* Option B:Correct-Adding spine devices decreases the oversubscription ratio.
質問 # 20
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.)
正解：A、D
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 # 21
You are implementing VXLAN broadcast domains in your data center environment. Which two statements are correct in this scenario? (Choose two.)
正解：B、C
解説：
Layer 2 frames are encapsulated by the source VTEP: In a VXLAN environment, Layer 2 frames (Ethernet frames) are encapsulated by the source VTEP (VXLAN Tunnel Endpoint) into VXLAN packets. The VTEP adds a VXLAN header to the original Layer 2 frame and forwards the encapsulated packet over the IP network to the destination VTEP.
A VXLAN packet does not contain a VLAN ID: VXLAN operates at Layer 2 and encapsulates Ethernet frames within a VXLAN header, but it does not carry a traditional VLAN ID as part of the encapsulated packet. Instead, it uses a VXLAN Network Identifier (VNI) to identify the broadcast domain.
