1. If a router cannot find a valid configuration file during the startup sequence, what
will occur?
The startup sequence will reset.
*The router will prompt the user for a response to enter setup mode.
The startup sequence will halt until a valid configuration file is acquired.
The router will generate a default configuration file based on the last valid
configuration.
The router will monitor local traffic to determine routing protocol configuration
requirements.
2. Refer to the exhibit. work administrator has configured the router with the
interface IP addresses shown for the directly works. Pings from the
router to hosts on the works or pings between router interfaces are not
working. What is the most likely problem?
The works do not exist.
The IP addresses on the router interfaces must be configured work addresses
and not host addresses.
* The interfaces must be enabled with the no mand.
Each interface must be configured with the clock mand.
3.
Refer to the exhibit. What can be concluded from the routing table output in the
exhibit? (Choose two.)
This router only has two interfaces.
The router interfaces are not operational yet.
This router is configured to forward packets to works.
* The 0/0 and Serial0/0/0 interfaces of this router were configured with
an IP address and the no mand.
* An IP packet received by this router with a destination address of will be
forwarded out of the Serial0/0/0 interface.
4.
Refer to the exhibit. The frame shown in the exhibit was received by the router. The
router interfaces are operational. How will the router process this frame? (Choose
two.)
The router will change the source and destination IP address in the packet before
forwarding the frame.
* The router will change the frame type to one supported by the WAN link before
forwarding the frame.
The router will use the destination MAC address to determine which interface to
forward the packet.
