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.
Correct Answer: 2.4GHz
Explanation:
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.
Correct Answer: Router> trace
Explanation:
The command
traceroute (trace for short), which can be issued from user mode or privileged mode, is used to find the path a packet takes through an internetwork and will also show you where the packet stops because of an error on a router.
Correct Answer: The port is experiencing errors.
Explanation:
When you connect to a switch port, at first the link lights are orange/amber, and then they turn green, indicating normal operation. If the link light is blinking, you have a problem.
Correct Answer: EIGRP
Explanation:
In this question, we're calling EIGRP just plain old distance vector. EIGRP is an "advanced" distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics of both distance-vector and link-state routing protocols.
Correct Answer: Router(config-router)# passive-interface s0
Explanation:
The
(config-router)#passive-interface command stops updates from being sent out an interface, but route updates are still received.
