You ping a remote device by name from a router, and the ping operation returns this response. What are two reasons for this problem? (Choose two.)
A. An ACL on the router blocked the ping.
B. A firewall blocked the ping.
C. The DNS server database does not include a record for the name.
D. The router is blacklisted by the DNS server.
E. Only one DNS server is configured on the router.
I think A and C
