CCNA 1 module 7 Exam
the Layer 3 protocol selected
>the geographic scope of the network
the PDU defined by the transport layer
>the physical layer implementation
>the number of hosts to be interconnected
2.Refer to the exhibit. Assuming that the network in the exhibit is converged meaning the routing tables and ARP tables are complete, which MAC address will Host A place in the destination address field of Ethernet frames destined for www.server?
00-1c-41-ab-c0-00
>00-0c-85-cf-65-c0
00-0c-85-cf-65-c1
00-12-3f-32-05-af
3.Which options are properties of contention-based media access for a shared media? (Choose three.)
>non-deterministic
>less overhead
one station transmits at a time
>collisions exist
devices must wait their turn
token passing
4.What is true concerning physical and logical topologies?
The logical topology is always the same as the physical topology.
Physical topologies are concerned with how a network transfers frames.
Physical signal paths are defined by Data Link layer protocols.
>Logical topologies consist of virtual connections between nodes.
5.What determines the method of media access control? (Choose two.)
network layer addressing
>media sharing
application processes
>logical topology
intermediary device function
6.What is true regarding media access control? (Choose three.)
>Ethernet utilizes CSMA/CD
>defined as placement of data frames on 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
controlled access contains data collisions
7. Which statements describe the logical token-passing topology? (Choose two.)
Network usage is on a first come, first serve basis.
>Computers are allowed to transmit data only when they possess a token.
Data from a host is received by all other hosts.
>Electronic tokens are passed sequentially to each other.
Token passing networks have problems with high collision rates.
8.A network administrator has been asked to provide a graphic representation of exactly where the company network wiring and equipment are located in the building. What is this type of drawing?
logical topology
>physical topology
cable path
wiring grid
access topology
9.What is the purpose of the preamble in an Ethernet frame?
is used as a padding for data
>is used for timing synchronization
is used to identify the source address
is used to identify the destination address
10.What statements are true regarding addresses found at each layer of the OSI model? (Choose two.)
>Layer 2 may identify devices by a physical address burned into the network card
Layer 2 identifies the applications that are communicating
>Layer 3 represents a hierarchical addressing scheme
Layer 4 directs communication to the proper destination network
Layer 4 addresses are used by intermediary devices to forward data
11.Refer to the exhibit. Which statement describes the media access control methods that are used by the networks in the exhibit?
All three networks use CSMA/CA
None of the networks require media access control.
Network 1 uses CSMA/CD and Network 3 uses CSMA/CA.
Network 1 uses CSMA/CA and Network 2 uses CSMA/CD.
Network 2 uses CSMA/CA and Network 3 uses CSMA/CD.
12.Refer to the exhibit. How many CRC calculations will take place as traffic routes from the PC to the laptop?
