Which Ethernet standard is specially encoded for transmission over WANs using SONET technology |
10GBase-SW |
|
|
A server on the network containing a faulty NIC and the overall network length exceeding IEEE 802.3 standards for the network type are two reasons that could cause what? |
Excessive data collisions on an Ethernet network |
|
|
In what example would workstations share a collision domain? |
Two computers connected to the same hub |
|
|
Which type of 10 Gbps ethernet can carry signals the farthest, nearly 25 miles? |
10GBase-ER |
|
|
What depends on wavelength and fiber core diameter? |
The maximum segment length for a 1000Base-FX network. |
|
|
Which expansion board NIC provides the highest transmission rate? |
PCIe |
|
|
If the on-board NIC on an office laptop stops working, and the person is connected to a 1 Gbps Ethernet network, which type of NIC connector replacement would provide best performance? |
USB Version 3 |
|
|
Which WAN type are the most fault tolerant type because they provide multiple routes for data to follow between any two points? |
Mesh |
|
|
ISDN PRI uses how many B channels and one 64-Kbps D channel? |
23 |
|
|
What is an updated, digital version of X.25 that again relies on packet switching? |
Frame relay |
|
|
What sets ATM apart from Ethernet? |
Its fixed packet size |
|
|
SONET's extraordinary what results from its use is a double-ring topology over fiber optic cable? |
Fault tolerance |
|
|
What is the minimum cabling standard required for 10GBase-T Ethernet? |
Cat 6 |
|
|
Why is packet switching more efficient than circuit switching? |
In packet switching, packets can take the quickest route between nodes and arrive independently of when other packets in their data steam arrive. |
|
|
What backbone for is the most fault tolerant? |
Parallel backbone |
|
|
Which backbone type will be down if the central router fails? |
Collapsed backbone |
|
|
Which switching method will best guarantee the utmost QoS? |
MPLS |
|
|
What happens in CSMA/CD when a node detects that its data has suffered a collision? |
It signals to the network that its data was damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data |
|
|
You are designing a 100Base-T network To connect groups of workstations in two different offices in your building. The offices are 250 meters apart. If you only use repeating devices to correct the workstation groups, how many hubs will you need? |
Two |
|
|
On a 10Base-T network, what best describes how the wires of a UTP cable are used to transmit and receive data? |
One wire pair handles data transmission, while another wire pair handles data reception. |
|
|
All four wire pairs are used for both transmission and reception is a technique used to achieve what? |
1Gbps throughput over a Cat 5 cable |
|
|
10GBase-SW is an Ethernet standard specially encoded for what? |
Transmission over WAN s using SONET technology |
|
|
What is an example of how workstations necessarily share a collision domain? |
Two computers connected to the same hub |
|
|
No LEDs being lit is a sign of what? |
A NIC not operating properly |
|
|
What routing protocol is used on the internet's backbone? |
BGP |
|
|
When is a packet discarded when using the RIP routing method? |
When it has been passed from one connectivity device to another 16 times. |
|
|
What type of address does a router interpret? |
Network address |
|
|
What type of routing protocol allows routers to exchange information about best paths with their neighboring routers only? |
Link-state |
|
|
Which protocol was developed by Cisco Systems and has a day convergence time but is supported only on Cisco routers? |
EIGRP |
|
|
What does OSPF stand for? |
Open shortest path first |
