In the LAN for a small office, some user devices connect to the LAN using a cable,
while others connect using wireless technology (and no cable). Which of the following
is true regarding the use of Ethernet in this LAN?
Only the devices that use cables are using Ethernet.
Only the devices that use wireless are using Ethernet.
Both the devices using cables and those using wireless are using Ethernet.
None of the devices are using Ethernet.
Which of the following Ethernet standards defines Gigabit Ethernet over UTP cabling?
10GBASE-T
100BASE-T
1000BASE-T
None of the other answers is correct.
Which of the following is true about Ethernet crossover cables for Fast Ethernet?
Pins 1 and 2 are reversed on the other end of the cable.
Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable.
Pins 1 and 2 on one end of the cable connect to pins 3 and 4 on the other end of the cable.
The cable can be up to 1000 meters long to cross over between buildings.
None of the other answers is correct.
Each answer lists two types of devices used in a 100BASE-T network. If these devices were connected with UTP Ethernet cables, which pairs of devices would require a straight-through cable? (Choose three answers.)
PC and router
PC and switch
Hub and switch
Router and hub
Wireless access point (Ethernet port) and switch
Which of the following are advantages of using multimode fiber for an Ethernet link instead of UTP or single-mode fiber?
To achieve the longest distance possible for that single link.
To extend the link beyond 100 meters while keeping initial costs as low as possible.
To make use of an existing stock of laser-based SFP/SFP+ modules.
To make use of an existing stock of LED-based SFP/SFP+ modules.
Which of the following is true about the CSMA/CD algorithm?
The algorithm never allows collisions to occur.
Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover.
The algorithm works with only two devices on the same Ethernet.
None of the other answers is correct.
Which of the following is true about the Ethernet FCS field?
Ethernet uses FCS for error recovery.
It is 2 bytes long.
It resides in the Ethernet trailer, not the Ethernet header.
It is used for encryption.
Which of the following are true about the format of Ethernet addresses? (Choose three answers.)
Each manufacturer puts a unique OUI code into the first 2 bytes of the address.
Each manufacturer puts a unique OUI code into the first 3 bytes of the address
Each manufacturer puts a unique OUI code into the first half of the address.
The part of the address that holds this manufacturer’s code is called the MAC.
The part of the address that holds this manufacturer’s code is called the OUI
Which of the following terms describe Ethernet addresses that can be used to send
one frame that is delivered to multiple devices on the LAN? (Choose two answers.)
Burned-in address
Unicast address
Broadcast address
Multicast address

add, beyond the ISO standard HDLC?

FCS
Two routers, R1 and R2, connect using an Ethernet over MPLS service. The service
provides point-to-point service between these two routers only, as a Layer 2 Ethernet
service. Which of the following are the most likely to be true about this WAN?
(Choose two answers.)
R1 will connect to a physical Ethernet link, with the other end of the cable connected to R2.
R1 will connect to a physical Ethernet link, with the other end of the cable connected to a device at the WAN service provider point of presence.
R1 will forward data-link frames to R2 using an HDLC header/trailer.
R1 will forward data-link frames to R2 using an Ethernet header/trailer.
Imagine a network with two routers that are connected with a point-to-point HDLC serial link. Each router has an Ethernet, with PC1 sharing the Ethernet with Router1
and PC2 sharing the Ethernet with Router2. When PC1 sends data to PC2, which of the following is true?
Router1 strips the Ethernet header and trailer off the frame received from PC1, never to be used again.
Router1 encapsulates the Ethernet frame inside an HDLC header and sends the frame to Router2, which extracts the Ethernet frame for forwarding to PC2.
Router1 strips the Ethernet header and trailer off the frame received from PC1, which is exactly re-created by Router2 before forwarding data to PC2.
Router1 removes the Ethernet, IP, and TCP headers and rebuilds the appropriate headers before forwarding the packet to Router2.
Which of the following does a router normally use when making a decision about routing TCP/IP packets?
Destination MAC address.
Source MAC address.
Destination IP address
Source IP address
Destination MAC and IP addresses
Which of the following are true about a LAN-connected TCP/IP host and its IP routing (forwarding) choices?
The host always sends packets to its default gateway.
The host never sends packets to its default gateway.
The host sends packets to its default gateway if the destination IP address is in a different subnet than the host.
The host sends packets to its default gateway if the destination IP address is in the same subnet as the host.
Which of the following are functions of a routing protocol? (Choose two answers.)
Advertising known routes to neighboring routers.
Learning routes for subnets directly connected to the router.
Learning routes and putting those routes into the routing table for routes advertised to the router by its neighboring routers.
Forwarding IP packets based on a packet’s destination IP address.
A company implements a TCP/IP network, with PC1 sitting on an Ethernet LAN. Which of the following protocols and features requires PC1 to learn information from some other server device?
