Factors Determining EC2 Network Performance

Answer - B,C and D.

The following factors can determine the EC2 Network performance.

1)EC2 instance size.

Larger instance sizes for an instance type typically provide better network performance than smaller instance sizes of the same type.

2)EC2 instance maximum transmission unit (MTU)

3)Location of the EC2 Instance.

EC2 Network performance can be affected by various factors, and the following are the three major factors that can determine it:

A. The EBS volume attached:

The Elastic Block Store (EBS) volume attached to the EC2 instance can impact the network performance. EBS volumes are network-attached storage devices that use the same network interface as the EC2 instances. The network throughput and IOPS (input/output operations per second) of the EBS volume affect the overall network performance of the EC2 instance. Therefore, it is essential to choose the appropriate EBS volume based on the workload requirements to achieve optimal network performance.

B. EC2 instance size:

The size of the EC2 instance can also impact the network performance. EC2 instances are available in various sizes that offer different levels of network performance. For example, instances with larger vCPUs and higher memory capacity have higher network bandwidth than smaller instances. Therefore, selecting the appropriate instance size is critical to achieve optimal network performance based on the workload requirements.

C. Location of the EC2 Instance:

The physical location of the EC2 instance can also affect the network performance. The distance between the client and the EC2 instance can cause latency, packet loss, and reduced network bandwidth. Therefore, it is essential to choose the appropriate AWS Region and Availability Zone based on the geographical location of the clients to achieve optimal network performance.

D. EC2 instance maximum transmission unit (MTU):

Although MTU is an important networking parameter, it is not included in the options. Therefore, this factor is not relevant to this question. MTU is the largest size of a data packet that can be transmitted over a network. EC2 instances have a default MTU size of 1500 bytes, but larger MTUs can improve the network performance by reducing the overhead of packet fragmentation and reassembly. However, larger MTUs can also increase the risk of packet loss and network congestion if not configured correctly.
