An administrator needs to assign a static IP address to the NDB VM using the...

The command era-server > era server set ip=ip_address gateway=gateway_address netmask=ip_netmask nameserver=ns1 ntp_server=ntp1 is used to assign a static IP address to the NDB VM via the era-server CLI. This command requires core network parameters (ip, gateway, and netmask) to configure the VM’s network interface correctly. However, optional parameters like nameserver (DNS server) and ntp_server (Network Time Protocol server) can be omitted if the administrator relies on default or externally configured DNS and NTP settings (e.g., via DHCP or another management system). These optional parameters enhance functionality but are not mandatory for the basic static IP configuration.

Option A (ntp_server) is correct as it is optional and can be configured separately or omitted if NTP is managed externally.

Option B (netmask) is incorrect because the netmask is a required parameter to define the subnet for the IP address.

Option C (gateway) is incorrect because the gateway is a required parameter to specify the network route.

Option D (nameserver) is correct as it is optional and can be omitted if DNS is handled outside NDB.

Note: The typos in the question (gatevay_address, ip_J2etmas^c, narnesetver, ntpl) are assumed to be gateway_address, ip_netmask, nameserver, and ntp1 based on context.
