Network+ N10-008 ACTUAL UPDATED Questions and CORRECT
Answers
1. The common use Backbone cabling in oflce networks and for workstations with high bandwidth
of Fiber requirements, such as video editing.
Applications of 10GbE are:
> Increasing bandwidth for server interconnection and network backbones for
SANs.
> Replacing existing switched public data networks based on proprietary tech with
simpler ethernet switches.
2. CE Customer Edge: router placed at the network perimeter for the customer.
3. SOHO Router Small Oflce / Home Oflce: Designed to work with DSL or Cable Broadband Access
4. PE Provider Edge: router placed at the network perimeter for the provider.
5. Computer Com- View and modify the routing table of end Windows/Linux systems
mand: Route
6. Computer Com- shows the routing table for end devices
mand: route
print
7. Computer To add a route, the syntax for the Windows version of the tool is:
Command: route
add 192.168.3.0 route [-f -p] add DestinationIP mask Netmask
mask GatewayIP metric MetricValue if Interface
255.255.255.0
192.168.5.1
metric 2
8. (UDP - Linux) allows you to test the whole path between two nodes to find a link

oute
9. Computer Com- (ICMP - Window) allows you to test the whole path between two nodes to find a
mand: Tracert link problem
10. Routing Loop When two routers use one another as the path to a network.
11. Split Horizon Used by routing protocols to prevent routing loops.
Prevents a routing update from being copied back to the source.
12. Holddown Timer Used by routing protocols to prevent routing loops. If a node declares a network
unreachable, its neighbors start a holddown timer. Any updates about that route
received from other nodes are discarded for the duration of the timer.
13. Maximum Hop Used by routing protocols to prevent routing loops.
Count
If the cost exceeds a certain value (16 for RIP), the network is deemed unreach-
able.
14. Asymmetrical a topology where the return path is different to the forward path. Common with
Routing load balancers where routing takes place over multiple redundant paths.
15. Optical Link Bud- The amount of loss suffered by all components along a fiber transmission path.
get (Loss Budget) The following is used to calculate this:
Attenuation - loss over the length of the cable.
Connectors - each connector in the path incurs a loss budgeted at .75 dB.
Splices - Additional splices in the cable are budgeted at around 1 dB for loss.
16. Peer-to-Peer a network where each end systems acts as both client and server.

17. Client-Server a network where some nodes act mostly as clients and connect to servers.
18. LAN Local Area Network. network type that is confined to a single geographical loca-
tion. All nodes and segments are directly connected with cables or short-ranged
wireless technologies.
Home/Residential Network.
Small Home/Home Oflce (SOHO).
Small and Medium-sized enterprise (SME) Networks.
Enterprise LANS.
Datacenters.
19. Home/Residen- A type of LAN.
tial Network
A network with an internet router, a few computers, mobile devices, gaming
consoles, and printer.
20. Small Office / A type of LAN. Also known as a SOHO network.
Home Office
A business-oriented network possible using a centralized server in addition to
client devices and printers, but often still using a single internet router/switch/ac-
cess point to provide connectivity.
21. Small and Medi- A type of LAN.
um-Sized Enter-
prise (SME) Net- A network supporting dozens of users. Such networks would use structured
works cabling and multiple switches and routers to provide connectivity.
22. Enterprise LANs A type of LAN.
A larger network with hundreds or thousands of servers and clients. Such net-
works would require multiple enterprise-class switch and router appliances to
maintain performance levels.

Answers
The term Campus Area Network (CAN) is sometimes used for a LAN that spans
multiple nearby buildings.
23. Datacenters A type of LAN.
A network that hosts only servers and storage, not end user client devices.
24. WLAN A type of LAN.
A wireless LAN that is based on Wi-Fi. Open WLANs are often referred to as
hotspots.
25. WAN Wide Area Network.
A network of networks, connected by long-distance links.
26. MAN Metropolitan Area Network.
Sometimes used for something a bit smaller than a WAN. A city-wide network
encompassing multiple buildings.
27. PAN / WPAN Personal Area Network / Wireless Personal Area Network.
Networks where a person might establish close-range network links between a
variety of devices, such as smartphones, tablets, headsets, and printers. Networks
connected by Bluetooth.
28. Star Topology Each endpoint node is connected to a central forwading node, such as a hub,
switch, or router.
Most widely used physical topology.
Easy to configure and troubleshoot.
