so i'm thinking of going for my CCNA, but i have my doubts as to whether i can actually pass it, any tips? also the cert only lasts for 3 years... then need to pay another thousand to get it renewed... da fuck
Study a lot. CCNA is hard.
Also, CCNA materials are easy to find in internet.
Download CISCO PACKET TRACER. Is a excellent tool
CCNA is not easy, so study a lot
Altough you might already know this.

i figured this... as of right now i'm just thinking about it, haven't signed up to take it yet so might just wait for the information from this years exams to be uploaded to demonoid or something and take it next year
then need to pay another thousand to get it renewed... da fuck
paying for this yourself would be a serious case of self abuse.
also you won't pass if you don't know the answers and be sufficiently competent on the matter.
To a A rating you also have to buy a used 2600 on ebay.

Going for a CCNA, eh? It's not hard per se, it's just very in-depth.
Memorize the following:
TCP/IP and OSI layers (including the logical link control sublayer)
protocols at each layer
process of encapsulation and decapsulation
protocol data units for each layer
common port numbers
ephemeral ports
sockets
how to subnet
how to supernet (route summarization)
binary to decimal conversion
decimal to binary conversion
subnet masking
variable-length subnet masking
classless inter-domain routing
frame relay
ARP
broadcasting vs. multicasting vs. unicast
the different fields and headers/trailers in different packets (especially TCP, IP, and UDP)
Cisco IOS command line
Windows command line
LAN switching
network topologies
provisioning, priority, QoS, etc.
network address translation
private address spaces (and which class they fall under)
public address spaces (and which class they fall under)
ANDing
ADDing
routing tables
RIP (and the differences between the different versions)
broadcast domains
collision domains
media access control
standards
physical layer medium
end devices vs. intermediary devices and etc.
IPv4 vs. IPv6 (although the current version of the CCNA doesn't cover much on IPv6, you still need to know at least a little bit about it (they won't ask you to do any IPv6 subnetting though))
MUAs, MTAs, MDAs, etc.... everything related to SMTP, POP, and IMAP
wireless standards and their differences
link aggregation/trunk lines
WANs vs. LANs
DNS
scalability
public keys
private keys
basic cryptography
collision detection vs. collision avoidance
DHCP
segmentation and reassembly
the three-way handshake
establishing connections
ending connections
next-hop addressing
the tradeoffs between reliability vs. low overhead (and when it's appropriate to use different protocols)
connection-oriented and reliable vs. connectionless and unreliable protocols
gateways
static and dynamic routing
attenuation
crosstalk
port forwarding
DMZ
logical vs. physical topology
physical signaling methods
legacy shit
network planning
troubleshooting network problems
using SSH to remotely administrate Cisco IOS devices
load balancing
distance vector routing
serial vs. parallel
VLANs
routing vs. switching (and when to use what)
multiplexing
hierarchical networking
converged networking
traffic flow
congestion
latency
MAC address flooding
ARP cache spoofing
packet sniffing
CDP attacks
penetration testing
port stealthing
frame tagging
security
spanning tree
redundancy
jitter
bridges
domains
workgroups
VTP
synchronization
distribution
identifying bottlenecks
DDoSing (and how to protect against it)
synchronous vs. asynchronous transfers
bandwidth vs. throughput
tunnels
propagation
network management
etc.
Subnetting is really important. If you can't quickly calculate class B and class C subnetting problems in your head, then you're probably going to run out of time on the exam. The thing about the CCNA is that even if you know all the material on the exam, you might still fail if you aren't quick enough.

oh yeah, and another somewhat useful thing to learn is data inference
although it might not necessarily be on the CCNA, it's a neat networking topic
Example: Joe is thinking of a number between 1 and 10, and the only instruction he is given is that he can't tell you when you're correct. But he can still tell you when you're wrong. So you guess until you know all the wrong numbers and then you can infer what the right one is. That's an extremely basic example, but you get the idea.
