- Question
If an Ethernet port on a router were assigned an IP address of 172.16.112.1/25, what would be the valid subnet address of this host?
Options- A. 172.16.112.0
- B. 172.16.0.0
- C. 172.16.96.0
- D. 172.16.255.0
- Correct Answer
- 172.16.112.0
ExplanationA /25 mask is 255.255.255.128. Used with a Class B network, the third and fourth octets are used for subnetting with a total of 9 subnet bits, 8 bits in the third octet and 1 bit in the fourth octet. Since there is only 1 bit in the fourth octet, the bit is either off or on-which is a value of 0 or 128. The host in the question is in the 0 subnet, which has a broadcast address of 127 since 128 is the next subnet. - 1.

Correct Answer: 12
Explanation:
Layer 2 switching creates individual collision domains.
Correct Answer: About 90-100 feet
Explanation:
The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 90 to 100 feet.
Correct Answer: line vty 0 4
Explanation:
The command
line vty 0 4 places you in a prompt that will allow you to set or change your Telnet password.
Correct Answer: 255.255.255.224
Explanation:
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts-this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
Correct Answer: frame-relay map
Explanation:
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.
Correct Answer: Server
Explanation:
Only in server mode can you change VTP information on a switch.
Correct Answer: 8 subnets, 8,190 hosts each
Explanation:
A CIDR address of /19 is 255.255.224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
Correct Answer: debug ip nat
Explanation:
The command
debug ip nat will show you in real time the translations occurring on your router.
Correct Answer: 802.1Q
Explanation:
802.1Q was created to allow trunked links between disparate switches.
Correct Answer: show ip eigrp topology
Explanation:
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the
show ip eigrp topology command.
