350-601 Question #422: Real Exam Question with Answer & Explanation

Question

Refer to the exhibit. An engineer is troubleshooting intermittent connect issues between the client PC and the DHCP server. What does the last package captured from the Cisco Nexus 2000 Series Switch indicate?

Options

• AThe DCHP server releases the IP address from the client.
• BThe client receives an IP address from the DHCP server.
• CThe DHCP server sends an IP address via a broadcast message.
• DThe client sends a unicast message to receive an IP address from the DCHP server.

Explanation

Troubleshooting intermittent connectivity issues between a client and DHCP server by analyzing packet captures requires understanding the DHCP DORA process and release messages.

Common mistakes.

• B. If the client received an IP address, the last packet would typically be a DHCPACK, signifying a successful lease, which contradicts the problem of intermittent connectivity.
• C. The DHCP server sending an IP address via a broadcast message (DHCP OFFER) is an earlier step in the DORA process and not usually the last message in a troubleshooting scenario involving release issues.
• D. The client sending a unicast message to receive an IP address (DHCPREQUEST) is an intermediate step in the DORA process, not the final message indicating a problem like an intermittent connection due to an address release.

Concept tested. DHCP DORA process and DHCPRELEASE messages
