Explanation: Radio Frequency Interference (RFI) is the
interference that is caused by radio transmitters and other
devices that are transmitting in the same frequency.
14. Which two statements describe the services provided by
the data link layer? (Choose two.)
It defines the end-to-end delivery addressing scheme.
It maintains the path between the source and destination
devices during the data transmission.
It manages the access of frames to the network media.
It provides reliable delivery through link establishment and
flow control.
It ensures that application data will be transmitted according
to the prioritization.
It packages various Layer 3 PDUs into a frame format
that is compatible with the network interface.
Explanation: The data link layer is divided into two sub
layers, namely Logical Link Control (LLC) and Media Access
Control (MAC). LLC forms a frame from the network layer
PDU into a format that conforms to the requirements of the
network interface and media. A network layer PDU might be
for IPv4 or IPv6. The MAC sub layer defines the media
access processes performed by the hardware. It manages
the frame access to the network media according to the
physical signaling requirements

* to verify the logical address in the frame
■ to compute the checksum header for the data field in the
frame
Explanation: The CRC value in the FCS field of the
received frame is compared to the computed CRC value of
that frame, in order to verify the integrity of the frame. If the
two values do not match, then the frame is discarded.
16. What is contained in the trailer of a data-link frame?
* logical address
* physical address
■ data
■ error detection
Explanation: The trailer in a data-link frame contains error
detection information that is pertinent to the frame included

Explanation: All data link layer protocols encapsulate the
Layer 3 PDU within the data field of the frame. However, the
structure of the frame and the fields that are contained in the
header vary according to the protocol. Different data link
layer protocols may use different fields, like priority/quality of
service, logical connection control, physical link control, flow
control, and congestion control.
18. A network team is comparing physical WAN topologies
for connecting remote sites to a headquarters building.
Which topology provides high availability and connects
some, but not all, remote sites?
• mesh
• partial mesh
• hub and spoke
• point-to-point
Explanation: Partial mesh topologies provide high
availability by interconnecting multiple remote sites, but do
not require a connection between all remote sites. A mesh
topology requires point-to-point links with every system
being connected to every other system. A point-to-point
topology is where each device is connected to one other
device. A hub and spoke uses a central device in a star
topology that connects to other point-to-point devices.
19. Which two fields or features does Ethernet examine to
determine if a received frame is passed to the data link layer
or discarded by the NIC? (Choose two.)
* auto-MDIX
* CEF
* Frame Check Sequence

calculated frame check sequence (FCS) value does not
match the received FCS value. Auto-MDIX (automatic
medium-dependent interface crossover) is Layer 1
technology that detects cable straight-through or crossover
types. The source MAC address is not used to determine
how the frame is received. CEF (Cisco Express Forwarding)
is a technology used to expedite Layer 3 switching.
20. Which media communication type does not require media
arbitration in the data link layer?
’ deterministic
* half-duplex
* full-duplex
* controlled access
Explanation: Half-duplex communication occurs when both
devices can both transmit and receive on the medium but
cannot do so simultaneously. Full-duplex communication
occurs when both devices can transmit and receive on the
medium at the same time and therefore does not require
media arbitration. Half-duplex communication is typically
contention-based, whereas controlled (deterministic) access
is applied in technologies where devices take turns to
access the medium.

* End devices connect to a central intermediate device,
which in turn connects to other central intermediate
devices.
* End devices are connected together by a bus and each bus
connects to a central intermediate device.
■ Each end system is connected to its respective neighbor via
an intermediate device.
* All end and intermediate devices are connected in a chain to
each other.
Explanation: In an extended star topology, central
intermediate devices interconnect other star topologies.
22. What is a characteristic of the LLC sublayer?
• It provides the logical addressing required that identifies the
device.
• It provides delimitation of data according to the physical
signaling requirements of the medium.
• It places information in the frame allowing multiple Layer
3 protocols to use the same network interface and
media.
■ It defines software processes that provide services to the
physical layer.
Explanation: The Logical Link Control (LLC) defines the
software processes that provide services to the network
layer protocols. The information is placed by LLC in the
frame and identifies which network layer protocol is being
used for the frame. This information allows multiple Layer 3
protocols, such as IPv4 and IPv6, to utilize the same network
interface and media.

23. What are three ways that medi
networking? (Choose three.)
is used in
Ethernet utilizes CSMA/CD.
• Media access control provides placement of data frames
onto the media.
■ Contention-based access is also known as deterministic.

* 802.11 utilizes CSMA/CD.
■ Data link layer protocols define the rules for access to
different media.
* Networks with controlled access have reduced performance
due to data collisions.
Explanation: Wired Ethernet networks use CSMA/CD for
media access control. IEEE 802.11 wireless networks use
CSMA/CA, a similar method. Media access control defines
the way data frames get placed on the media. The controlled
access method is deterministic, not a contention-based
access to networks. Because each device has its own time
to use the medium, controlled access networks such as
legacy Token Ring do not have collisions.
24. During the encapsulation process, what occurs at the
data link layer for a PC connected to an Ethernet network?
• An IP address is added.
• The logical address is added.
• The physical address is added.
• The process port number is added.
Explanation: The Ethernet frame includes the source and
destination physical address. The trailer includes a CRC
value in the Frame Check Sequence field to allow the
receiving device to determine if the frame has been changed
(has errors) during the transmission.
25. What three items are contained in an Ethernet header and
trailer? (Choose three.)
* source IP address

* Frame start and stop indicator flags at the beginning
and end of a frame
* Addressing - for Ethernet networks this part of the
header contains source and destination MAC addresses
■ Type field to indicate what Layer 3 protocol is being
used
* Error detection to determine if the frame arrived without
error
26. What type of communication rule would best describe
CSMA/CD?
• access method
* flow control
* message encapsulation
• message encoding
Explanation: Carrier sense multiple access collision
detection (CSMA/CD) is the access method used with
Ethernet. The access method rule of communication dictates
how a network device is able to place a signal on the carrier.
CSMA/CD dictates those rules on an Ethernet network and
CSMA/CA dictates those rules on an 802.11 wireless LAN.
27. Which three basic parts are common to all frame types
supported by the data link layer? (
’ header
• type field
• MTU size
’ data
