Which of the following is true of CSMA/CD? (Select two.)
Two devices can transmit at the same time without collisions occurring.
Only devices with information to send have access to the transmission media.
A device with data to send first listens to the transmission medium to determine whether it is free.
After a collision, sending devices run the same algorithm before sending their messages again.
If collisions are detected, an interrupt jam signal is broadcast to stop all transmissions.
You want to prevent collisions on your network by creating separate collision domains and defining virtual LANs. Which of the following devices should you choose?
Bridge
Switch
Active Hub
Router
What role does ARP play in the routing process?
If a router does not know a destination device's MAC address, it sends an ARP broadcast containing the destination device's IP address and requesting its MAC address.
If a router knows the MAC and IP address of a destination host, it sends an ARP request to update the other routers' route tables.
ARP does not play any role in the routing process. Switches use ARP to map IP addresses to MAC addresses in collision domains.
If a router does not know a destination device's IP address, it sends an ARP broadcast containing the destination device's MAC address and requesting its IP address.
The process of breaking a message into packets, adding control information and other information, and then transmitting the message through the transmission medium is known as __________?
Transformation
Encapsulation
Segmentation
Sequencing
How does TCP handle data sequencing?
TCP breaks the data into segments, numbers each segment, and passes them to UDP, which sequences the segments into the correct order.
TCP breaks user data into segments, numbers each segment, and sends each segment in order, without waiting for an acknowledgement.
TCP breaks user data into segments, numbers each segment, places them in the correct sequence, and sends each one in order, waiting for an acknowledgement before sending the next segment.
TCP does not sequence the data; it simply passes numbered segments created at a higher layer in the sequence defined.
Which of the following are limitations of the TCP/IP model? (Select two.)
Forces modularity in networking features.
Divides networking tasks into logical layers.
Does not aid in troubleshooting.
A particular protocol implementation may not represent every layer.
TCP/IP layers are theoretical and do not actually perform real functions.
What term does the OSI model use that is different from the TCP/IP model uses to refer to frame, packet, and segment?
Presentation
Protocol data unit (PDU)
Session
IEEE Ethernet standard
What is the maximum cable length for UTP Ethernet T implementations?
300 meters
40 kilometers
10 kilometers
100 meters
You want to implement an Ethernet network using the 1000BaseT standard using the minimum hardware specifications possible. Which of the following should you include in your plan? (Select two.)
RJ-45 connectors
Cat4 twisted pair cable
Multi-mode fiber optic cable
Cat5 twisted pair cable
Cat5e twisted pair cable
Which of the following are general advantages of using routers on your network? (Select three.)
Routers support multiple routing protocols for better flexibility.
Routers provide guaranteed bandwidth between two devices.
Routers provide less functionality than bridges or switches.
Routers provide multiple links between devices to support load balancing.
Routers provide more features, such as flow control, error detection, and congestion control, than switches or bridges.
What is the purpose of a network model?
Provide the logical addressing required to locate your destination node.
Provide an interface for submitting web requests.
Used to remotely access application on remote systems.
Standardize processes at each layer.
You are deploying a new 10GB Ethernet network using Cat 6 cabling.
Which of the following are true concerning this media? (Select two.
It supports multi-mode transmissions.
It is completely immune to EMI.
It supports 10 GB Ethernet connections.
PVC insulation surrounds each copper wire.
It uses twisted 18- or 16-gauge copper wiring.
Put the OSI model layers in order.
