問題 #37
Exhibit.
Referring to the exhibit, Host1 (10.1.1.1) is failing to communicate with Host2 (10.1.2.1) in a data center that uses an ERB architecture. What do you determine from the output?
答案：D
解題說明：
Understanding the Problem:
* Host1 (10.1.1.1) is failing to communicate with Host2 (10.1.2.1) within an EVPN-VXLAN environment using ERB architecture.
Analysis of the Exhibit:
* The provided output includes information from the show route forwarding-table matching command for IP 10.1.2.1. The next hop is shown as vtep.32769, which indicates that the traffic destined for 10.1.2.1 is being forwarded into the VXLAN tunnel with the correct VTEP (VXLAN Tunnel Endpoint).
Conclusion:
* Option B:Correct-The traffic from Host1 is entering the VXLAN tunnel, as evidenced by the next hop pointing to a VTEP. However, the issue could lie elsewhere, possibly with the remote VTEP, routing configurations, or the receiving leaf/spine devices.
問題 #38
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.)
答案：C,D
解題說明：
* 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.
問題 #39
Exhibit.
The exhibit shows the truncated output of the show evpn database command.
Given this output, which two statements are correct about the host with MAC address 40:00:dc:01:00:04?
(Choose two.)
答案：A,B
解題說明：
* Understanding the Output:
* The show evpn database command output shows the MAC address, VLAN, active source, timestamp, and IP address associated with various hosts in the EVPN instance.
* Analysis of the MAC Address:
* Option A:The MAC address 40:00:dc:01:00:04 is associated with the IP address 10.4.4.5, as indicated by the output in the IP address column. This confirms that this host has been assigned the IP 10.4.4.5.
* Option D:The active source for the MAC address 40:00:dc:01:00:04 is listed as 00:02:00:00:00:
04:00:04:00:00:04:00:04, which indicates that the host is connected via an ESI (Ethernet Segment Identifier) LAG (Link Aggregation Group). This setup is typicallyused in multi-homing scenarios to provide redundancy and load balancing across multiple physical links.
Conclusion:
* Option A:Correct-The host with MAC 40:00:dc:01:00:04 is assigned IP 10.4.4.5.
* Option D:Correct-The host is originating from an ESI LAG, as indicated by the active source value.
問題 #40
A local VTEP has two ECMP paths to a remote VTEP
Which two statements are correctwhen load balancing is enabled in this scenario? (Choose two.)
答案：A,C
解題說明：
* Load Balancing in VXLAN:
* VXLAN uses UDP encapsulation to transport Layer 2 frames over an IP network. For load balancing across Equal-Cost Multi-Path (ECMP) links, various fields in the packet can be used to ensure even distribution of traffic.
* Key Load Balancing Fields:
* C. The source port in the UDP header is used to load balance VXLAN traffic:This is correct.
The source UDP port in the VXLAN packet is typically calculated based on a hash of the inner packet's fields. This makes the source port vary between packets, enabling effective load balancing across multiple paths.
* D. The inner packet fields are used in the hash for load balancing:This is also correct. Fields such as the source and destination IP addresses, source and destination MACaddresses, and possibly even higher-layer protocol information from the inner packet can be used to generate the hash that determines the ECMP path.
* Incorrect Statements:
* A. The inner packet fields are not used in the hash for load balancing:This is incorrect as the inner packet fields are indeed critical for generating the hash used in load balancing.
* B. The destination port in the UDP header is used to load balance VXLAN traffic:This is incorrect because the destination UDP port in VXLAN packets is typically fixed (e.g., port 4789 for VXLAN), and therefore cannot be used for effective load balancing.
Data Center References:
* Effective load balancing in VXLAN is crucial for ensuring high throughput and avoiding congestion on specific links. By using a combination of the source UDP port and inner packet fields, the network can distribute traffic evenly across available paths.
問題 #41
Exhibit.
Referring to the exhibit, when Host A sends an ARP request for Host B's IP address, which Junos feature does leaf1require to send an ARP response back to Host A without having to send a broadcast frame over the fabric?
答案：D
解題說明：
* Scenario Overview:
* In the exhibit, Host A is trying to resolve Host B's IP address (10.10.1.2) through ARP (Address Resolution Protocol). Normally, an ARP request would be broadcasted over the network, and the host owning the IP address (Host B) would respond.
* Role of Proxy ARP:
* Option A:Proxy ARPallows a router or switch (in this case, leaf1) to respond to ARP requests on behalf of another host. Leaf1, knowing the MAC address of Host B through the EVPN MAC advertisement, can reply to Host A's ARP request directly without broadcasting the request across the entire network fabric. This feature reduces unnecessary traffic and increases network efficiency.
Conclusion:
* Option A:Correct-Proxy ARP enables leaf1 to respond to Host A's ARP request for Host B's IP without broadcasting over the IP fabric, thus providing the ARP response locally.
