The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.
