There is a mismatch in the encapsulation type on both ends of the link.
* A Layer 1 issue exists.
* An interface problem exists.
The clockrate was not set during configuration.

includes technologies of FDDI and Ethernet

* common carriers are needed for connections
type of connection between a router and a switch
90. Which of the following are true statements about creating and applying access lists? (Choose three.)
Access list entries should filter in the order from general to specific.
One access list per port per protocol per direction is permitted.
Standard ACLs should be applied closest to the source while extended ACLs should be applied closest to the destination.
* There is an implicit deny at the end of all access lists.
* Statements are processed sequentially from top to bottom until a match is found.
* The inbound keyword refers to traffic entering the network from the router interface where the ACL is applied.
91. Refer to the network and routing table entries shown in the graphic. What will happen when a packet destined for network 192.66.7.0 is received by Router A?
It will be forwarded through interface S1.
It will be forwarded to the default route.
It will be directed toward the Internet.
* It will be discarded.
92. Refer to the output from the show ip route command. What can be concluded from the output of this router command?
A preferred route to the destination has not been set.
* There are two equal cost paths to network 1.0.0.0.
Both interfaces are being used equally to route traffic.
A variance must be set to load-balance across multiple paths.
93. Assume OSPF is being used on all routers. What happens when the link between Router1 and Router2 goes down? (Choose two.)
Updates start broadcasting every 30 seconds.
Updates start broadcasting every 90 seconds.
* Link-state advertisements are flooded.
Link-state advertisements are sent only to neighboring routers.
* All routers note the change and adjust routes.
All routers ignore the change until the route becomes active again.
94. A network administrator can establish a remote session to a host using the Router> telnet 192.168.1.1 command but is unsuccessful when using the Router> telnet Boston command to connect to the same interface. Which of the following could be the problem? (Choose two.)
* The ip host table on the router is not configured.
The command telnet Boston was issued from the wrong router prompt.
The routing table is missing.
* Domain name services are not available.
95. The following line was displayed in the output of the show ip route command.
I 192.168.3.0/24 [100/80135] via 192.168.2.2, 00:00:30, Serial0/0
What is the value of the composite metric?
8
24
80
100
135
* 80135
96. In the configuration register value 0x2104, which value represents the boot field setting?
x
2
1
0
* 4
97. Why would an administrator use the Telnet application when troubleshooting a network? (Choose three.)
* It can be used to verify the operation of application layer software between the source and destination.
Telnet can use the ICMP protocol to verify a hardware connection and network layer address.
* It is the most complete testing mechanism available.
* Remote networks may be accessed via a Telnet session for troubleshooting.
Time to Live values are used by Telnet to identify a failure of device between source and destination.
98. Which of the following WAN connection services typically use synchronous communications? (Choose two.)
circuit-switched
* leased line
packet-switched
Ethernet
* analog modem services
