Answers

1
What is a characteristic of the LLC sublayer?
Delimits data according to physical signaling requirements of the medium.
It defines software processes that provide services to the physical layer.
It provides the logical addressing required that identifies the device.
Allows Layer 3 protocols to use the same network interface and media.
2
Which is NOT a way that media access control is used in networking?
Contention-based access is also known as deterministic.
Ethernet utilizes CSMA/CD.
Data link layer protocols define the rules for access to different media.
Media access control provides placement of data frames onto the media.
3
Which statement describes an extended star topology?
Hosts are connected to its respective neighbor via an intermediate device.
Hosts are connected by a bus and each bus connects to a network device.
All end and intermediate devices are connected in a chain to each other.
Hosts connect to network device, which connects to other network devices
4
What does Ethernet examine to determine if a received frame is passed to the data link layer or discarded by the NIC?
Source and Destination IP Address
Frame Check Sequence and Minimum Frame Size
Source and Destination MAC Address
Auto-MDIX and CEF
5
What is the function of the CRC value that is found in the FCS field of a frame?
To verify the physical address in the frame
To verify the integrity of the received frame
To verify the logical address in the frame
To compute the checksum header for the data field in the frame
6
Which topology provides high availability and connects some, but not all, remote sites?
Hub and Spoke
Mesh
Point-to-Point
Partial mesh
7
Which media communication type does not require media arbitration in the data link layer?
Deterministic
Controlled access
Half-duplex
Full-duplex
8
Which statement does NOT describe the services provided by the data link layer?
It manages the access of frames to the network media.
Divided into two sub layers, namely LLC and MAC
It defines the end-to-end delivery addressing scheme.
Packages Layer 3 PDUs into a frame format that is compatible with the NIC
9
What is contained in the trailer of a data-link frame?
Physical address
Data
Logical address
Error detection
10
Which statement describes a characteristic of the frame header fields of the data link layer?
They include information on user applications.
Ethernet frame header contain Layer 3 source and destination addresses.
They all include the flow control and logical connection fields.
They vary depending on protocols.
