A network engineer is monitoring a fiber uplink to a remote office and notes the uplink has been operating at 100% capacity for a long duration. Which of the following performance metrics is MOST likely to be impacted with sustained link saturation?
Its bandwidth. Per Comptia Certmaster bandwidth is a performance metric, not speed. "Bandwidth/throughput-This is the rated speed of all the interfaces available to the device, measured in Mbps or Gbps. For wired Ethernet links, this will not usually vary, but the bandwidth of WAN and wireless links can change over time."
You’re correct, in the context of a risk assessment and planning for mitigation, Bandwidth (Option D) would indeed be a key performance metric to consider. Bandwidth, often measured in Mbps or Gbps, refers to the maximum amount of data that can be transmitted over a network link within a given time.
When a network link is operating at 100% capacity for an extended period, the performance metric most likely to be impacted is A. Latency.
Sustained link saturation can lead to delays in data transmission, causing latency to increase. Network packets may be queued, resulting in longer wait times before they are transmitted. High latency can adversely affect real-time applications like video conferencing and online gaming, as well as general network responsiveness.
Option B, Jitter, is also affected by link saturation as congestion can lead to packet reordering and varying inter-packet timing, but latency is typically more noticeably impacted.
Options C and D, Speed and Bandwidth, refer to the capacity of the link itself. When a link is saturated, it's already operating at its full speed and capacity, so they are not the metrics that are directly impacted by saturation; it's the resulting latency and jitter that become more noticeable performance issues.
When a network link is fully saturated, it causes delays in the processing and transmission of packets. This is because the network devices handling the traffic are operating at their maximum capacity, leading to increased queuing and waiting times for packets. As a result, latency, or the time it takes for data to travel from the source to the destination, increases.
Tricky one, I'm going with C. The bandwidth is performing to 100% capability, therefore performing as expected. However the potential maximum speed (e.g a client device) might expect will be IMPACTED if the bandwidth is maxed out.
Latency is dependent on the NTP to ensure consistent data transfer, this should not change much during office network usage.
Jitter is the symptom that would occur from bad/incorrect latency usage.
Answer is speed, because when a network, or device starts to hit full capacity for too long, it's speed will start slowing down to ensure there are not any potential data drops which is why a system eventually has to restart from being used @ 100% too long.
Bandwidth is potential amount of data that can be sent.
Bandwidth: Sustained link saturation typically occurs when the available bandwidth is fully utilized, so bandwidth itself is not impacted. However, the effective use of available bandwidth may be affected.
In summary, sustained link saturation is likely to increase latency, causing delays in data transmission and affecting network performance.
In the scenario of sustained link saturation, where a network link is consistently operating at its maximum capacity, managing and potentially increasing the bandwidth could indeed be a strategy for mitigation. My previous responses were focused on the immediate impact of link saturation (increased latency), but certainly, considering bandwidth as part of a longer-term mitigation strategy is valid and important.
What is most likely to be impacted? Latency or network delay is a network performance metric measuring the amount of time it takes to transfer data from one destination to another.
Speed and bandwidth are going to remain the same, even if operating at 100% capacity. You could also view this as operating at 100% efficentcy. However a saturated link is going to cause delays as packets queque for transmission. So the bandwidth doesnt decrease, and the speed at wich the packets are sent doesnt decrease but that actual time it takes to go from point A to B will probably take longer.
D, because performance affects bandwidth, think of bandwidth as a performance metric that is the most important from the answer choices. jitter is an effect, speed and latency are not as important as bandwidth
I will choose latency. Although I would have gone for Bandwidth, but the badnwidth is always the same100%. Too many waiting on queue affects their latency?
A. My answer
Latency, amount of time data could go from A to B. Saturated network will take a long time,.as it waits for its turn to go transfer since its operating at 100%.
Speed is how fast data could go. Speed will not be affected and stay the same.
Bandwidth is how much data could go A to B. Amount of data will stay the same.
When a fiber uplink is operating at 100% capacity for a long duration, the most likely performance metric to be impacted is bandwidth.
Bandwidth refers to the amount of data that can be transmitted over a network connection within a certain time period. When a link is saturated, all available bandwidth is being used, which can lead to delays in data transmission and reduced throughput.
The performance metric that is MOST likely to be impacted by sustained link saturation is latency. Latency is the time it takes for a data packet to travel from one point to another on a network. When a network link is operating at 100% capacity for a long duration, it can cause congestion and delay in the transmission of packets, which results in an increase in latency. High latency can affect the quality and performance of network applications, such as voice, video, or gaming. Latency can be measured by using tools such as ping or traceroute.
