Refer to the exhibit. The network administrator issues the command no ip classless on Router1. What forwarding action will take place on a packet that is received by Router1 and is destined for host 192.168.0.26?

The packet will be dropped.
The packet will be forwarded to the gateway of last resort.
The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.
The packet will most closely match the 192.168.0.8 subnet and be forwarded out Serial 0/1

Refer to the exhibit. Which statement is true concerning the routing configuration?

Using dynamic routing instead of static routing would have required fewer configuration steps.
The 10.1.1.0/24 and 10.1.2.0/24 routes have adjacent boundaries and should be summarized.
Packets routed to the R2 Fast Ethernet interface require two routing table lookups.
The static route will not work correctly

Refer to the exhibit. How many routes are child routes?

Refer to the exhibit. How many routes are child routes?
1
3

Which router component is used to store the routing table?

Flash
NVRAM
ROM
SDRAM

When a router boots, what is the default order to locate the Cisco IOS if there is no boot system command?

ROM, TFTP server, flash
flash, TFTP server, ROM
flash, NVRAM, TFTP server
NVRAM, TFTP server, flash

What are two functions of a router? (Choose two.)

It connects multiple IP networks.
It controls the flow of data via the use of Layer 2 addresses.
It determines the best path to send packets.
It manages the VLAN database.
It increases the size of the broadcast domain

On a router, which three components are stored in RAM? (Choose three.)

POST code
the routing table
the running-configuration
the start-up configuration
the bootstrap instructions
a copy of the operating system

Refer to the exhibit. The network is configured with RIPv2. However, network administrators notice that communication cannot be successfully completed from one LAN to another. A network administrator issues the show ip route command on the HQ router. Based on the output, what should be done to correct the problem?

Disable the load balancing feature of RIPv2.
Issue the no auto-summary command for RIPv2.
Replace RIPv2 with EIGRP which supports VLSM.

Refer to the exhibit. Hosts on the 192.168.1.0 network cannot communicate with hosts on the 172.16.1.1 network. The network administrator has run the show ip route command on R1.

What could be the cause of this problem?

The FastEthernet interface on R1 is disabled.

What is a function of the console port on a router?

It is used to manage the router.
It is used for packet receiving and forwarding.
It is used to interconnect various types of LANs.
It is used to interconnect a variety of serial links including T1, DSL, and ISDN.

Refer to the exhibit. What is the purpose of the ip bandwidth-percent eigrp 50 10 command?

to limit the bandwidth EIGRP packets can use to 6.4 kb/s
to limit the bandwidth EIGRP packets can use to 10 kb/s

A router boots and enters setup mode. What is the reason for this?

The IOS image is corrupt.
Cisco IOS is missing from flash memory.
The configuration file is missing from NVRAM.
The POST process has detected hardware failure.

Which three statements are true regarding the encapsulation and de-encapsulation of packets when traveling through a router? (Choose three.)

The router modifies the TTL field, decrementing it by one.
The router changes the source IP to the IP of the exit interface.
The router maintains the same source and destination IP.
The router changes the source physical address to the physical address of the exit interface.
The router changes the destination IP to the IP of the exit interface.
The router sends the packet out all other interfaces, besides the one it entered the router on.
