Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?

It is the IP address of the Router1 interface that connects the company to the Internet.
It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.

It is the IP address of the ISP network device located in the cloud.

Which two functions are primary functions of a router? (Choose two.)

What is the effect of using the Router# copy running-config startup-config command on a router?

The contents of ROM will change.
The contents of RAM will change.
The contents of NVRAM will change.
The contents of flash will change.

What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with other hosts in the local network.
The switch will not forward packets initiated by the host.
The host will have to use ARP to determine the correct address of the default gateway.
The host cannot communicate with hosts in other networks.
A ping from the host to 127.0.0.1 would not be successful.

What are two potential network problems that can result from ARP operation? (Choose two.)

Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.
Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.
Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.

Which information is used by routers to forward a data packet toward its destination?

source IP address
destination IP address
source data-link address
destination data-link address

A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?

The packet will be sent to the default gateway first, and then, depending on the response from the gateway, it may be sent to the destination host.
The packet will be sent directly to the destination host.
The packet will first be sent to the default gateway, and then from the default gateway it will be sent directly to the destination host.
The packet will be sent only to the default gateway.

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

route the packet out the Gigabit 0/1 interface
create a new Layer 2 Ethernet frame to be sent to the destination
look into the ARP cache to determine the destination IP address
look into the routing table to determine if the destination network is in the routing table

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

126.0.0.1
127.0.0.0
126.0.0.0
127.0.0.1

A computer can access devices on the same network but cannot access devices on other networks. What is the probable cause of this problem?

The cable is not connected properly to the NIC.
The computer has an invalid IP address.
The computer has an incorrect subnet mask.
The computer has an invalid default gateway address.

Which statement describes a feature of the IP protocol?

IP encapsulation is modified based on network media.
IP relies on Layer 2 protocols for transmission error control.
MAC addresses are used during the IP packet encapsulation.
IP relies on upper layer services to handle situations of missing or out-of-order packets.

Why is NAT not needed in IPv6?

Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.
The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.
The end-to-end connectivity problems that are caused by NAT are solved because the number of routes increases with the number of nodes that are connected to the Internet.

Which parameter does the router use to choose the path to the destination when there are multiple routes available?

the lower metric value that is associated with the destination network
the lower gateway IP address to get to the destination network
the higher metric value that is associated with the destination network
the higher gateway IP address to get to the destination network

What are two services provided by the OSI network layer? (Choose two.)

performing error detection
routing packets toward the destination
encapsulating PDUs from the transport layer
placement of frames on the media
collision detection

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

Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination.
A switch must have a default gateway to be accessible by Telnet and SSH.
The default gateway address is used to forward packets originating from the switch to remote networks.
It provides a next-hop address for all traffic that flows through the switch.

What is a basic characteristic of the IP protocol?

connectionless
media dependent
user data segmentation
reliable end-to-end delivery

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

Time-to-Live
Sequence Number
Acknowledgment Number
Differentiated Services

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

smaller-sized header
little requirement for processing checksums
smaller-sized source and destination IP addresses
efficient packet handling

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

Protocol
Identification
Version
Differentiated Services

Refer to the exhibit. Match the packets with their destination IP address to the exiting interfaces on the router. (Not all targets are used.)

The TCP/IP stack on the device is working correctly.
The device has end-to-end connectivity.
DHCP is working correctly.
The Ethernet cable is working correctly.
The device has the correct IP address on the network.

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

directly-connected routes
local routes
remote routes
C and L source routes

How do hosts ensure that their packets are directed to the correct network destination?

They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route.
They always direct their packets to the default gateway, which will be responsible for the packet delivery.
They search in their own local routing table for a route to the network destination address and pass this information to the default gateway.
They send a query packet to the default gateway asking for the best route.

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?

Next Header
Flow Label

The frame has the broadcast address as the destination address.
The destination address is unknown to the switch.
The source address in the frame header is the broadcast address.
The source address in the frame is a multicast address.
The destination address in the frame is a known unicast address.
