| Question ID 14501 | An administrator must assign static IP addresses to the servers in a network. For network
192.168.20.24/29, the router is assigned the first usable host address while the sales
server is given the last usable host address.
Which of the following should be entered into the IP properties box for the sales server?
|
| Option A | IP address: 192.168.20.14 Subnet Mask: 255.255.255.248 Default Gateway: 192.168.20.9
|
| Option B | IP address: 192.168.20.254 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.20.1
|
| Option C | IP address: 192.168.20.30 Subnet Mask: 255.255.255.248 Default Gateway: 192.168.20.25
|
| Option D | IP address: 192.168.20.30 Subnet Mask: 255.255.255.240 Default Gateway: 192.168.20.17
|
| Option E | IP address: 192.168.20.30 Subnet Mask: 255.255.255.240 Default Gateway: 192.168.20.25
|
| Correct Answer | C |
Explanation Explanation: With network 192.168.20.24/29 we have: Increment: 8 (/29 = 255.255.255.248 = 11111000 for the last octet) Network address: 192.168.20.24 (because 24 = 8 * 3) Broadcast address: 192.168.20.31 (because 31 = 24 + 8 1) Therefore the first usable IP address is 192.168.20.25 (assigned to the router) and the last usable IP address is 192.168.20.30 (assigned to the sales server). The IP address of the router is also the default gateway of the sales server.
| Question ID 14502 | Which command enables IPv6 forwarding on a Cisco router?
|
| Option A | ipv6 host
|
| Option B | ipv6 unicast-routing
|
| Option C | ipv6 local
|
| Option D | ipv6 neighbor
|
| Correct Answer | B |
Explanation Explanation: Enabling IPv6 on Cisco IOS Software Technology http://www.ciscopress.com/articles/article.asp?p=31948&seqNum=4 The first step of enabling IPv6 on a Cisco router is the activation of IPv6 traffic forwarding to forward unicast IPv6 packets between network interfaces. By default, IPv6 traffic forwarding is disabled on Cisco routers. The ipv6 unicast-routing command is used to enable the forwarding of IPv6 packets between interfaces on the router. The syntax for this command is as follows: Router(config)#ipv6 unicast-routing The ipv6 unicast-routing command is enabled on a global basis.
