What is one main characteristic of the data link layer?

It converts a stream of data bits into a predefined code.

It shields the upper layer protocol from being aware of the physical medium to be used in the communication.

It accepts Layer 3 packets and decides the path by which to forward the packet to a remote network.

Which type of security threat would be responsible if a spreadsheet add-on disables the local software firewall?

What service is provided by HTTPS?

Allows remote access to network devices and servers.

Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)

Destination MAC addresses will never change in a frame that goes across seven routers.

A packet that has crossed four routers has changed the destination IP address four times.

Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed.

Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another.

Destination IP addresses in a packet header remain constant along the entire path to a target host.

when the values of both the Echo Request and Echo Reply messages reach zero

when the value in the TTL field reaches zero

when the router receives an ICMP Time Exceeded message

when the host responds with an ICMP Echo Reply message

when the RTT value reaches zero

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

A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

the network domain of the destination host

the MAC address of the default gateway

the IP address of the default gateway

the MAC address of the destination host

Which two commands can be used on a Windows host to display the routing table? (Choose two.)

route print

show ip route

netstat -r

netstat -s

tracert

A technician with a PC is using multiple applications while connected to the Internet. How is the PC able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows?

The data flow is being tracked based on the source port number that is used by each application.

The data flow is being tracked based on the destination IP address that is used by the PC of the technician.

The data flow is being tracked based on the source IP address that is used by the PC of the technician.

The data flow is being tracked based on the destination MAC address of the technician PC.

A client packet is received by a server. The packet has a destination port number of 80. What service is the client requesting?

DNS

HTTP

DHCP

SMTP

A user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? (Choose two.)

source port number

HTTP server

source MAC address

DNS server

default gateway

CSMA/CD

priority ordering

CSMA/CA

token passing

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in the ARP cache. How will the device obtain a destination MAC address?

It will send an ARP request for the MAC address of the destination device.
