CERTIPORT FINAL EXAM ACTUAL QUESTIONS AND
ANSWERS RATED A+
✔✔3 Properties of VLANs - ✔✔1)Requires a router
2) Isolate traffic
3) Create same LAN regardless of physical location, reduce nodes in broadcast
✔✔Cat 3 (Category 3) - ✔✔10Mbps 100m (10BaseT)
✔✔CAT 5(Category 5) - ✔✔100Mbps 100m (100BaseT)
✔✔Cat 5e (Enhanced Category 5) - ✔✔1000Mbps 100m (1000BaseT)
✔✔CAT 6(Category 6) - ✔✔1Gbps/10Gbps 100m/55m (1000BaseT)
✔✔What is minimum cable needed for 100Mbps? - ✔✔Cat 5
✔✔What is the max distance of UTP 5 cable? - ✔✔99.97m 328 feet
✔✔Which can travel the furthest distance multi-mode or single-mode fiber? - ✔✔Fiber
Optic Cables support splicing and requires polished connectors
✔✔CSMA/CD (Carrier Sense Multiple Access with Collision Detection) - ✔✔detects
collisions and listens for when the media is idle to send
✔✔Hubs - ✔✔Simple devices that connect network components, sending a packet of
data to all other connected devices
always floods all ports and is less efficient
✔✔Switch - ✔✔A computer networking device that connects network segments
Associates network Address to Port, uses switching table
sends packets to destination ports if it knows where to go
floods all ports if it does not
can send and receive simultaneously
sends broadcast to all ports
✔✔Multi-layer or Layer 3 - ✔✔provide Layer 3 functions and can understand IP
addresses where Layer 2 switches cannot
✔✔Managed Switches - ✔✔can create VLANs and use trunk ports to send VLAN traffic
Only Managed switches supports VLANs and remote configuration unmanaged one
cannot
✔✔Routers - ✔✔devices that connect different networks together
, are TCP/IP enabled and most popular type network today
forward traffic to other networks
✔✔Firewall - ✔✔software that runs on servers (often routers) that only allows traffic
through according to some set of security rules.
Device that protects internal network from internet
✔✔2.4Ghz - ✔✔is affected by cordless phones, microwaves, fluorescent lights
✔✔Class A IP Address - ✔✔Address: 1-126
Private Range: 10.x.x.x
Default mask: 255.0.0.0
Example: 63.0.0.0

✔✔loopback address - ✔✔Address: 127.0.0.1 - 127.255.255.255
Private Range:
Default mask:
Example:
✔✔NAT/PAT (Network Address Translation/Port Address Translation) - ✔✔masks
internal IP addresses private/public
✔✔IPv6 Addresses - ✔✔are 128-bit hexadecimal numbers
(example: 2001:7120:0000:8001:0000:0000:0000:1F10).
only 1 set of :: and made up of 8 16bit blocks
::1 is the loopback address. Unicast IPv6 addresses are assigned to a single interface
and are the most common type.
✔✔FE80 - ✔✔APIPA address
