A systems administrator would like to reduce the network delay between two servers. Which of the following will reduce the network delay without taxing other system resources?
C. Enable compression between the servers.
Enabling compression between the servers can help to reduce the network delay without taxing other system resources. Compression reduces the amount of data that needs to be transmitted over the network, thereby reducing the overall network delay. Compression can be particularly effective for data that is highly redundant or compressible, such as text files or log files.
C. ChatGPT approved.
Enabling compression will help reduce the amount of data that needs to be transmitted over the network, thereby potentially reducing the time it takes for data to travel between the two servers. This approach minimizes network delay without putting additional strain on CPU or other resources, as it primarily optimizes the data transfer itself.
Given the options and considering the potential impact on system resources, if I had to choose one, I would lean towards Option A: Decrease the MTU size on both servers.
While both options have their pros and cons, reducing the MTU size addresses potential delays caused by packet fragmentation, which can occur when packets are too large to traverse certain network segments without being fragmented. By reducing the MTU size, we aim to minimize the need for packet fragmentation, thus potentially reducing delays associated with retransmission of fragmented packets.
Additionally, adjusting the MTU size is a network-level configuration that doesn't directly impose additional computational overhead on the servers, unlike enabling compression. While decreasing the MTU size may lead to slightly more packets being sent, it generally doesn't require significant additional computational resources compared to compression.
However, it's important to note that the effectiveness of this approach depends on the specific network environment and the underlying causes of network delay that the question simply does not give us.
Increasing the MTU can improve performance, but decreasing the MTU can resolve packet loss and fragmentation problems when it is too high (and will not tax system resources like "enable compression" would).
As Maelo states, compression and decompression takes CPU resources to process. Reducing the MTU has ZERO affect on system resources (which is a requirement as per the question).
Compressed transmission needs compression and decompression processes before using the data. Reducing MTU size scales headers transmissions up, reduces transmission efficiency, but speeds up packet send/receive actions, not waiting for more data to fill the MTU. Extinguish a fire better with small buckets or big buckets? Throughput of reasonably small buckets is better.
A VPN tunnel would provide an opportunity for encryption and a virtual point-to-point connection for easier IP addressing, but the actual traffic would still flow through the same intermittent switches/routers. The additional overhead from the encryption and encapsulation would increase delay if anything.
depending on the application reducing the MTU will actually increase delay
