To extract the value "172.16.0.11" from the given JSON data, you need to navigate through the JSON structure using the correct keys and indices. The JSON structure provided is as follows:

"items": [{

"kind": "object#NetworkObj",

"selfLink": "https://10.201.230.5/api/objects/networkobjects/db01 ",

"name": "db01",

"host": {

"kind": "IPv4Address",

"value": "172.16.0.11"

},

"objectId": "db01"

}]

}

Access the 'items' key: This gives you a list containing one object.

Access the first object in the 'items' list: Using the index [0].

Access the 'host' key: This contains the 'kind' and 'value' keys.

Access the 'value' key within the 'host' object: This gives you the required value "172.16.0.11".

Thus, the correct way to access the value "172.16.0.11" is data['items'][0]['host']['value'].

By segmenting the network into separate subnets for clients and servers, you can control the types of traffic that flow between these segments using access control lists (ACLs) and firewall rules. This can enhance security by limiting access to critical server resources and reducing the risk of unauthorized access.

Subnets will split domains to limit failures (Option C):

Segmenting the network into different subnets helps contain network issues within a specific segment, preventing them from affecting the entire network. This approach improves network stability and reliability, as issues in the client subnet will not impact the server subnet and vice versa.

NETCONF (Network Configuration Protocol) is an IETF standard protocol used for managing network devices. By default, NETCONF operates over the SSH protocol on port 830. This default port is defined to separate NETCONF traffic from other types of SSH traffic, providing a dedicated channel for network configuration tasks.
