I have a question in service mapping

[BoHyun Jung]

Which one of the following best describes what will happen if Discovery is configured with 3 MID Servers in a Load Balance Cluster with Shazzam cluster support disabled?

A. All three MID Servers will be used during the Port Scan phase and all three will be used during the classification phase.

B. Only one MID Server will be used during the Identification phase and all three will be used during the exploration phase.

C. Only one MID Server will be used during the Port Scan phase and all three will be used during the classification phase.

D. All three MID Server will be used during the Identification phase and only one will be used during the exploration phase. 

Can you give me the correct answer and a detailed explanation?

Hi @BoHyun Jung ,

The correct answer is:

**C. Only one MID Server will be used during the Port Scan phase, and all three will be used during the classification phase.**

Explanation:

- In Discovery, the process involves several phases: Port Scan, Identification, Exploration, and Classification.

- When configured in a Load Balance Cluster without Shazzam cluster support, during the Port Scan phase, only one MID Server is typically used to avoid redundant port scans.

- During the Classification phase, all three MID Servers in the cluster are utilized to classify the devices discovered.

Therefore, option C accurately describes the behavior in this configuration.

Thanks,

Danish

Hi answer is

C. Only one MID Server will be used during the Port Scan phase and all three will be used during the classification phase.

When Discovery is configured with multiple MID Servers in a Load Balance Cluster, the behavior of the MID Servers during the different phases of Discovery can be affected. Additionally, the Shazzam cluster support setting plays a role in determining how MID Servers are utilized.

In the given scenario where Shazzam cluster support is disabled:

1. Port Scan Phase:

   • During the Port Scan phase, Discovery typically uses a single MID Server. This is because port scanning can be resource-intensive, and using multiple MID Servers simultaneously for port scanning might lead to inaccuracies or conflicts.
   • Therefore, only one MID Server will be used for the Port Scan phase.

2. Classification Phase:

   • During the Classification phase, where the discovered devices are identified and classified, all three MID Servers in the Load Balance Cluster can be utilized.
   • The classification phase is less resource-intensive compared to the port scan, so multiple MID Servers can be used simultaneously to process and classify discovered devices.

So, option C is the correct answer: Only one MID Server will be used during the Port Scan phase, and all three will be used during the classification phase.

The correct answer is:

C. Only one MID Server will be used during the Port Scan phase, and all three will be used during the classification phase.

Explanation:

In a Load Balance Cluster configuration with Shazzam cluster support disabled, the port scanning phase is typically handled by a single MID Server to prevent overlap and conflicts. However, during the classification phase, all MID Servers in the cluster will participate to distribute the workload and improve efficiency. This setup ensures that port scanning is done effectively without duplication of effort, while classification benefits from the combined resources of all MID Servers. Therefore, option C accurately describes the behavior in this configuration.
