Correct Answer: The split-MAC architecture allows the splitting of 802.11 protocol packets between the AP and the controller to allow processing by both devices.
Explanation:
The split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.
Correct Answer: show ip interface Ethernet 0
Explanation:
The only command that shows which access lists have been applied to an interface is
show ip interface Ethernet 0. The command
show access-lists displays all configured access lists, and
show ip access-lists displays all configured IP access lists, but neither command indicates whether the displayed access lists have been applied to an interface.
Correct Answer: 1 and 4
Explanation:
The
show hosts command provides information on temporary DNS entries and permanent name-to-address mappings created using the
ip host command.
Correct Answer: access-list 10 deny 172.16.144.0 0.0.7.255
Explanation:
First, you must know that a /21 is 255.255.248.0, which is a block size of 8 in the third octet. Counting by eight, this makes our subnet 144 in the third octet, and the wildcard for the third octet would be 7 since the wildcard is always one less than the block size.
Correct Answer: router eigrp 10
Explanation:
If you enable EIGRP on a router with the same autonomous system (AS) number, EIGRP will automatically redistribute IGRP into EIGRP. You will see the IGRP injected routes as external (EX) routes with an EIGRP AD of 170. This is a nice feature that lets you migrate slowly to EIGRP with no extra configuration.
Correct Answer: switchport mode trunk
Explanation:
To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the
switchport mode trunk command.
Correct Answer: VPN
Explanation:
A allows the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols. A VPN can be set up across any type of link.
Correct Answer: 2 and 3
Explanation:
The Cisco Unified Wireless Solution is a great product, but you must purchase specialized devices. Cisco managed access points and a controller are the devices you need to purchase to run the Unified Wireless Solution.
Correct Answer: 3 and 4
Explanation:
Adjacencies and next-hop attributes now use link-local addresses, and OSPFv3 still uses multicast traffic to send its updates and acknowledgments with the addresses
FF02::5 for OSPF routers and
FF02::6 for OSPF designated routers. These are the replacements for
224.0.0.5 and
224.0.0.6, respectively.
Correct Answer: 2, 3 and 5
Explanation:
The commands
show protocols,
show interfaces, and
show ip interface will show you the layer 1 and 2 status and the IP addresses of your router's interfaces.
