HPE Aruba Certified Central Associate (ACCA) — Question 53

The external DHCP server is configured with the IP address 192.168.1.100. The HPE Aruba Networking CX 6300M VSF is the L3 gateway for VLAN 200 clients, which should receive an IP address from the 192.168.200.0/24 subnet using the external DHCP address.
How do you configure the IPv4 DHCP relay on the specific HPE Aruba Networking CX 6300 switch?

Answer options

• A. interface vlan 200 ip address 192.168.200.1/24 ip helper-address 192.168.1.100
• B. interface vlan 1 ip address 192.168.200.1/24 ip helper-address 192.168.1.100
• C. interface vlan 1 ip address 192.168.200.1/24 dhcp-relay server 192.168.1.100
• D. interface vlan 200 ip address 192.168.200.1/24 dhcp-relay server 192.168.1.100

Correct answer: D

Explanation

The correct answer is D because it configures the DHCP relay for VLAN 200, which is essential for the clients in that VLAN to receive IP addresses from the specified external DHCP server. Option A incorrectly uses 'ip helper-address' instead of 'dhcp-relay server' and is not in the correct VLAN. Options B and C use VLAN 1, which is not the target VLAN for the clients requiring the DHCP service.
