Why might ping show successful replies but a web browser cannot load a website?
AThe website is down but ping caches results
BPing and HTTP use the same protocol, so this is impossible
CPing uses ICMP which may be allowed, but HTTP traffic is blocked by firewall
DThe computer's IP address changes during ping
Step-by-Step Solution
Solution:

  1. Step 1: Understand protocol differences

    Ping uses ICMP packets; web browsers use HTTP/HTTPS protocols over TCP.

  2. Step 2: Recognize firewall rules

    Firewalls may allow ICMP but block HTTP, causing ping success but no website loading.

  3. Final Answer:

    Ping uses ICMP which may be allowed, but HTTP traffic is blocked by firewall -> Option C

  4. Quick Check:

    Different protocols, firewall blocks HTTP only [OK]
Quick Trick: Ping uses ICMP; web uses HTTP blocked by firewall [OK]
Common Mistakes:
  • Assuming ping caches results
  • Believing protocols are the same
  • Thinking IP changes during ping
