which IPv4 address can a host use to ping the loopback interface?

127.0.0.1

using the network in the exhibit, what would be the default gateway address for host A in the 192.133.219.0 network? refer to the exhibit.

192.133.219.1

a packet leaving PC-1 has to traverse ____________ hops to reach PC-4.​ Refer to the exhibit. Fill in the blank.

3

which two pieces of information are in the RAM of a Cisco router during normal operation?

Cisco IOS IP routing table

what are two types of router interfaces?

LAN WAN

a router may have to fragment a packet when forwarding it from one medium to another medium that has a smaller

MTU

the acronym _______________ is used to define the process that allows multiple devices to share a single routable IP address.

Nat or Pat

perform the tasks in the activity instructions and then answer the question. which interfaces in each router are active and operational? open the PT activity.

R1: G0/0 and S0/0/0 R2: G0/1 and S0/0/0

match the command with the device mode at which the command is entered.

R1> enable R1# copy running-config startup-config R1(config-line)# login R1(config-if)# ip address 192.168.4.4 255.255.255.0 R1(config)# service password-encryption

Open the PT Activity. The enable password on SW1 is cisco. Perform the tasks in the activity instructions and then answer the question. For what reason is the failure occurring

SW1 does not have a default gateway configured.

which key combination allows a user to abort setup mode?

ctrl-c

what is one advantage that the IPv6 simplified header offers over IPv4?

efficient packet handling

during the boot process, where will the router bootstrap program look for the IOS image by default?

flash

when transporting data from real-time applications, such as streaming audio and video, which field in the IPv6 header can be used to inform the routers and switches to maintain the same path for the packets in the same conversation?

flow label

which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration?

it has two types of ports that can be used to access the console.

which three commands are used to set up secure access to a router through a connection to the console interface?

line console 0 login password cisco

following default settings, what is the next step in the router boot sequence after the IOS loads from flash?

locate and load the startup-config file from NVRAM.

what IPv4 header field identifies the upper layer protocol carried in the packet?

protocol

what routing table entry has a next hop address associated with a destination network?

remote routes

R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 forward the packet?

serial0/0/1

which characteristic describes an IPv6 enhancement over IPv4?​

the IPv6 header is simpler than the IPv4 header is, which improves packet handling.

how does the network layer use the MTU value?

the MTU is passed to the network layer by the data link layer

which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?

the ability to operate without regard to the data that is carried in each packet

what is the purpose of the startup configuration file on a Cisco router?

to contain the commands that are used to initially configure a router on startup

which portion of the network layer address does a router use to forward packets?

network portion

when a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.

which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?

time-to-Live

which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

time-to-live

what are two functions that are provided by the network layer? (Choose two.)

-providing end devices with a unique network identifier -directing data packets to destination hosts on other networks.

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

the configuration file is missing from NVRAM.

which route from the PC1 routing table will be used to reach PC2?

network destination 192.168.10.0 netmask 255.255.255.0 gateway on-link interface 192.168.10.10 metric 281

what type of route is indicated by the code C in an IPv4 routing table on a Cisco router?

directly connected route

what are two characteristics of IP?

does not require a dedicated end-to-end connection operates independently of the network media

if there are two or more possible routes to the same destination, the _______________ is used to determine which route is used in the routing table.

metric

within a production network, what is the purpose of configuring a switch with a default gateway address?

the default gateway address is used to forward packets originating from the switch to remote networks.
