ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 48

A PC can ping devices on VLAN 5 that are configured with static IP addresses, but it cannot ping other devices on VLAN 5 that receive their IP addresses from a
DHCP server. What are two root causes for the issue? (Choose two.)

Answer options

• A. The DHCP server scope is misconfigured
• B. The DNS server database is incorrect
• C. An ACL on the firewall blocked the ping.
• D. An ACL on the router is blocking DHCP messages.
• E. The PC failed to receive DHCP information from the DNS server. AD

Correct answer:

Explanation

The correct answers are A and D. If the DHCP server scope is misconfigured, it won't assign IP addresses properly, leading to connectivity issues. Additionally, if an ACL on the router is blocking DHCP messages, devices won't be able to receive their IP assignments, which would also prevent successful pings. Options B, C, and E are not relevant to the issue described.
