1. Which three factors should be considered when implementing a Layer 2 protocol in a network? (Choose three.)

the Layer 3 protocol selected
***** the geographic scope of the network
the PDU defined by the transport layer
***** the physical layer implementation
***** he 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 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
