Refer to the exhibit. On the basis of the output, which two statements about network connectivity are correct? (Choose two.)
This host does not have a default gateway configured.
There are 4 hops between this device and the device at 192.168.100.1.
There is connectivity between this device and the device at 192.168.100.1.
The connectivity between these two hosts allows for videoconferencing calls.
The average transmission time between the two hosts is 2 milliseconds.
Why would a Layer 2 switch need an IP address?
to enable the switch to send broadcast frames to attached PCs
to enable the switch to function as a default gateway
to enable the switch to be managed remotely
to enable the switch to receive frames from attached PCs

to enable the switch to send broadcast frames to attached PCs
to enable the switch to function as a default gateway

A client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?
It must send a DHCPv6 INFORMATION-REQUEST message to request the address of the DNS server.
It must send a DHCPv6 REQUEST message to the DHCPv6 server to request permission to use this address.
It must send an ICMPv6 Router Solicitation message to determine what default gateway it should use.
It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.
Refer to the exhibit. If PC1 is sending a packet to PC2 and routing has been configured between the two routers, what will R1 do with the Ethernet frame header attached by PC1?
nothing, because the router has a route to the destination network
open the header and use it to determine whether the data is to be sent out S0/0/0
open the header and replace the destination MAC address with a new one
remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0
What three requirements are defined by the protocols used in network communcations to allow message transmission across a network? (Choose three.)

The global configuration command ip default-gateway 172.16.100.1 is applied to a switch. What is the effect of this command?
The switch can communicate with other hosts on the 172.16.100.0 network.
The switch can be remotely managed from a host on another network.
The switch is limited to sending and receiving frames to and from the gateway 172.16.100.1.
The switch will have a management interface with the address 172.16.100.1.

What characteristic describes adware?
a network device that filters access and traffic coming into a network
software that is installed on a user device and collects information about the user
the use of stolen credentials to access private data
an attack that slows or crashes a device or network service
