Which scenario describes a function provided by the transport layer?
- A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window.
- A student is using a classroom VoIP phone to call home. The unique identifier burned into the phone is a transport layer address used to contact another network device on the same network.
- A corporate worker is accessing a web server located on a corporate network. The transport layer formats the screen so the web page appears properly no matter what device is being used to view the web site.
A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window.
What is the consequence of configuring a router with the ipv6 unicast-routing global configuration command?
- Each router interface will generate an IPv6 link-local address.
- The IPv6 enabled router interfaces begin sending ICMPv6 Router Advertisement messages.
- It statically creates a global unicast address on this router.
The IPv6 enabled router interfaces begin sending ICMPv6 Router Advertisement messages.
Which two protocols operate at the top layer of the TCP/IP protocol suite? (Choose two.)
POP DNS IP TCP Ethernet UDP
POP
DNS
An employee of a large corporation remotely logs into the company using the appropriate username and password. The employee is attending an important video conference with a customer concerning a large sale. It is important for the video quality to be excellent during the meeting. The employee is unaware that after a successful login, the connection to the company ISP failed. The secondary connection, however, activated within seconds. The disruption was not noticed by the employee or other employees.
What three network characteristics are described in this scenario? (Choose three.)
integrity scalability quality of service fault tolerance powerline networking security
security
quality of service
fault tolerance
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?
- 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
- Nothing, because the router has a route to the destination network
- Remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0
Remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0
Which three layers of the OSI model map to the application layer of the TCP/IP model? (Choose three.)
transport application network session data link presentation
presentation
application
session
Match each description with an appropriate IP address. (Not all options are used.)
a private address = a loopback address = an experimental address = a TEST-NET address = a link-local address =
- 102.90.23
- 2.6.255
- 254.1.5
- 19.20.5
- 0.2.123
- 0.0.1
a private address = 172.19.20.5 a loopback address = 127.0.0.1 an experimental address = 240.2.6.255 a TEST-NET address = 192.0.2.123 a link-local address = 169.254.1.5
What does the term “attenuation” mean in data communication?
strengthening of a signal by a networking device
leakage of signals from one cable pair to another
loss of signal strength as distance increases
time for a signal to reach its destination
loss of signal strength as distance increases
Which two statements describe how to assess traffic flow patterns and network traffic types using a protocol analyzer? (Choose two.)
- Capture traffic during peak utilization times to get a good representation of the different traffic types.
- Perform the capture on different network segments.
- Only capture WAN traffic because traffic to the web is responsible for the largest amount of traffic on a network.
- Only capture traffic in the areas of the network that receive most of the traffic such as the data center.
- Capture traffic during peak utilization times to get a good representation of the different traffic types.
- Perform the capture on different network segments.
Which subnet would include the address 192.168.1.96 as a usable host address?
- 168.1.32/27
- 168.1.32/28
- 168.1.64/29
- 168.1.64/26
192.168.1.64/26
What are two problems that can be caused by a large number of ARP request and reply messages? (Choose two.)
- A large number of ARP request and reply messages may slow down the switching process, leading the switch to make many changes in its MAC table.
- The ARP request is sent as a broadcast, and will flood the entire subnet.
- Switches become overloaded because they concentrate all the traffic from the attached subnets.
- All ARP request messages must be processed by all nodes on the local network.

Which two functions are performed at the MAC sublayer of the OSI Data Link Layer to facilitate Ethernet communication? (Choose two.)
- adds Ethernet control information to network protocol data
- integrates Layer 2 flows between 10 Gigabit Ethernet over fiber and 1 Gigabit Ethernet over copper
- handles communication between upper layer networking software and Ethernet NIC hardware
- implements CSMA/CD over legacy shared half-duplex media
- enables IPv4 and IPv6 to utilize the same physical medium
integrates Layer 2 flows between 10 Gigabit Ethernet over fiber and 1 Gigabit Ethernet over copper
implements CSMA/CD over legacy shared half-duplex media
Why would a Layer 2 switch need an IP address?
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 be managed remotely
How does the service password-encryption command enhance password security on Cisco routers and switches?
- It requires encrypted passwords to be used when connecting remotely to a router or switch with Telnet.
- It encrypts passwords that are stored in router or switch configuration files.
- It requires that a user type encrypted passwords to gain console access to a router or switch.
It encrypts passwords that are stored in router or switch configuration files.
