Exam CV0-003 topic 1 question 21 discussion

C. Move the web and database servers onto the same VXLAN. VXLAN (Virtual Extensible LAN) is a network virtualization technology that allows for the creation of virtual networks on top of physical networks. By moving the web and database servers onto the same VXLAN, the systems administrator can create a logical segmentation of the network, reducing the amount of traffic between the servers, and thus reducing the load on the network. A. Setting up affinity rules to keep the web and database servers on the same hypervisor will not help in resolving the issue as the traffic is between the servers not inside the hypervisor. B. Enabling jumbo frames on the gateway would help to improve network throughput by allowing for larger packets to be sent over the network, but this would not address the issue of overwhelming traffic between the web and database servers. D. Moving the servers onto thick-provisioned storage would not help in resolving the network throughput issues as it is a storage related concern not a network related one.

If the web server and database server are in the same VXLAN, network traffic becomes faster and more efficient because they are in one virtual network segment, reducing the load on the physical gateway and increasing throughput.

The systems administrator is facing network throughput issues due to excessive traffic between the database and web servers. The best way to address this is to optimize network traffic flow.

C is the correct answer.

Creates a logical network segment on top of a physical network. By placing the web servers and database servers on the same VXLAN, their communication can be encapsulated and tunneled within the VXLAN, effectively isolating their traffic from the rest of the network. This reduces congestion on the overall network and improves throughput.

Affinity rules ensure that specific virtual machines (VMs) run on the same physical hypervisor host. While this might improve communication between the web and database servers by reducing network latency, it does not address the underlying network throughput issue. Jumbo frames increase the Maximum Transmission Unit (MTU) size, which can reduce overhead and improve network efficiency. However, enabling jumbo frames requires support from all network devices in the path, including switches and routers. Additionally, it may not directly address the specific traffic congestion between the database and web servers. VXLAN (Virtual Extensible LAN) is a network virtualization technology that allows for the creation of logical networks overlaying existing Layer 3 infrastructure. Moving the web and database servers onto the same VXLAN can optimize network traffic by reducing hops and improving communication efficiency. Of these options C is the most optimized solution. A and B help to reduce latency across the board. But only C is specific enough to optimize where it needs it most. D is completely irrelevant.

"amount of traffic between the database and the web servers in the environment". Amount of traffic from one server to another, in "the" environment. Insinuating they're in the same environment so no gateway so not B.

A is more related to latency. Less latency might improve throughput, but the more relevant answer is B since it directly addresses throughput.

The question is about solving the problem of too much traffic between database and web server. A. Would solve this by grouping the database and webserver on same hypervisor. B. Jumbo frames would solve this by reducing packets, but there is no indication that packet size is the problem. C. vxLAN would solve this if there was 'other' traffic that was creating the congestion. vxLAN solves the problem of only 4096 possible network segments(mainly for CSPs). It also can create tunneling, so remote networks act as local and has traffic mirroring. None of these solutions directly correct this questions underlying problem. D. thick provision solves availability of storage with increased pricing. Not a storage problem.

Jumbo Frames Really!? That's the best CompTIA can come up with. Guess I'm going to get this question wrong, because I'm not going with stupid Jumbo Frames!

In some circumstances, using jumbo frames can result in better performance, while in others it can lower performance.In controlled networks with high utilization, using jumbo frames can lead to improved network throughput due to reduced overhead. https://www.techtarget.com/searchnetworking/definition/jumbo-frames

The correct option to resolve network throughput issues caused by overwhelming traffic between the database and web servers is: B. Enable jumbo frames on the gateway. Enabling jumbo frames increases the Maximum Transmission Unit (MTU) size, allowing larger packets to be transmitted over the network. This can reduce the overhead associated with transmitting smaller packets and potentially improve network throughput, especially in situations with high volumes of traffic between servers like databases and web servers. Options A, C, and D are not directly related to optimizing network throughput and may not address the specific issue of network congestion caused by the high traffic between the database and web servers.

I would choose Answer B "The network is currently being overwhelmed by the amount of traffic between the database and the web servers in the environment." It is often more efficient to use a larger Ethernet frame size than the standard Ethernet MTU inside the data center to reduce networking overhead. Jumbo frames allow for higher network performance by reducing the overhead in each Ethernet frame by using fewer but larger frames. Jumbo frames also reduce the number of times that a CPU will be interrupted to process Ethernet traffic since each jumbo frame can be up to six times as large as a standard frame.

It's not likely that the database and the web servers referenced are on different networks therefor none of the traffic would be traversing through a gateway.

Given the options provided, the most appropriate choice for resolving network throughput issues would be B. Enable jumbo frames on the gateway.

Affinity rules will ensure that the web and database servers are placed on the same physical host, reducing the network traffic and improving throughput by allowing for communication over the faster internal network.

Setting up affinity rules to keep web and database servers on the same hypervisor is the BEST option to resolve this issue. Affinity rules will ensure that the web and database servers are located on the same physical host, which will help reduce network latency and improve throughput. This will also help to improve performance as the network traffic will not have to traverse multiple hypervisors. Enabling jumbo frames on the gateway, moving the web and database servers onto the same VXLAN, and moving the servers onto thick-provisioned storage are not likely to resolve network throughput issues between web and database servers.
