chp 1 routing concepts Flashcards
1
Q
network characteristics
A
- topology
- speed
- cost
- security
- availability
- scalability
- reliability
2
Q
router job
A
-routing traffic between networks
3
Q
router components
A
- cpu
- memory and storage
- operating system
4
Q
router memory
A
- ram (random access)
- rom (read only)
- nvram (non-volatile random access)
- flash
5
Q
random access memory (ram)
A
- volatile
- runs ios
- running config
- ip routing and arp tables
- packet buffer
6
Q
read only memory (rom)
A
- non volatile
- bootup instructions
- diagnostic software
- back up ios
7
Q
non volatile random access memory (nvram)
A
- start up config
- non volatile
8
Q
flash
A
- non volatile
- stores ios
- system related files
9
Q
packet forwarding methods
A
- process switching
- fast switching
- cisco express forwarding (cef)
10
Q
process switching
A
- every packet is processed by the cpu
- destination ip address
- route table entry
- exit interface
11
Q
fast switching
A
- next hop is stored in cache
- first packet is processed by cpu
- other packets with the same destination are sent to cache not cpu
12
Q
cisco express forwarding (cef)
A
- fastest
- packets are change triggered
- forward information base (fib) and adjacency table forward packets
- fib and adjacency table populated when routers learn of other routers
13
Q
to have network access devices must have
A
- ip adress
- subnet mask
- default gateway
14
Q
network documentation should include
A
- topology diagram
- addressing table
15
Q
svi
A
- switch virtual interface
- used for management ip address
