Which statements are true regarding the significance of the access control list wildcard mask 0.0.0.7? (Choose two.)
The first 29 bits of a given IP address will be ignored.
The last 3 bits of a given IP address will be ignored.
The first 32 bits of a given IP address will be checked.
The first 29 bits of a given IP address will be checked.
The last 3 bits of a given IP address will be checked.

ACL statements operate in sequential, logical order. If a condition match is true, the rest of the ACL statements are not checked. If all of the ACL statements are unmatched, what happens to the packet?
The packets will be placed in a buffer and forwarded when the ACL is removed.
The packets will be sent to the source with an e......

IP source address
IP destination address
PAR
sliding window
port number
SYN packet

How does a source host use ICMP to confirm that a destination host is reachable?
The source host sends an ICMP echo request to the destination router which responds with an ICMP echo reply confirming the reachability of the destination host.
The source host sends a data packet and receives an ICMP host unreachable packet from the destination host if the data packet cannot be delivered.
The source host sends an ICMP packet with a TTL value of 1 and receives an ICMP reply with a TTL value of 0 from the destination host.
The source host sends an ICMP echo request and receives an ICMP echo reply from the destination host.
2
Which type of message is generated by a host when the ping command is entered?
ICMP echo request
ICMP echo reply
UDP e......
