I seem to have had some posts disappear, so once again, here are the answers to Friday's Cisco CCNA and CCNP practice questions!
CCNA:
What are the default criteria used to permit or deny traffic in an extended ACL?
Answer: In an extended ACL, both the source and destination IP addresses will be considered.
CCNP / BSCI:
What BGP attribute is specifically designed to prevent routing loops?
Answer: The AS_PATH attribute; if a router receives a BGP packet and sees its own AS number in the AS_PATH, that router knows a routing loop has occurred.
CCNP / BCMSN:
What interface-level command would place a port into a mode where it could send or receive data, but not do so simultaneously?
Answer: This describes half-duplex Ethernet, so the correct command will be duplex half.
CCNP / BCRAN:
What form of load balancing uses NAT as its primary mechanism?
Answer: TCP Load Distribution uses NAT.
CCNP / CIT:
What command output contains the following TCP and UDP statistics?
UDP statistics:
Rcvd: 0 total, 0 checksum errors, 0 no port
Sent: 2 total, 0 forwarded broadcasts
TCP statistics: Rcvd: 0 total, 0 checksum errors, 0 no port
Sent: 0 total
Answer: That's the partial output of show ip traffic.
I'll have Saturday's answers up in just a few minutes!
