From wireless networking to IP version 6, test your knowledge of important Cisco certification exam topics with these complimentary questions!
CCNA Certification:
In the world of wireless networking, what's the basic difference between an ESS and a BSS?
CCENT Certification:
Give the port numbers for each of these TCP-based protocols: FTP, SMTP, Telnet, HTTP, DNS, POP3, and NNTP.
CCNA Security Certification / CCNP ISCW Exam:
In SDM, what does an asterisk indicate when it's used in a graphical representation of an ACL?
CCNP Certification / BSCI Exam:
What is the shortest possible legal representation of the following IP version 6 address?
1234:1234:0000:0000:0000:0000:3456:3434
CCNP Certification / BCMSN Exam:
The use of Dynamic ARP Inspection is used to defend our network's switches against what network attack?
CCNP / ONT Exam:
What are the four basic steps of the analog-to-digital signal conversion process?
Here are the answers!
CCNA: While a Basic Service Set (BSS) will have a single AP, Extended Service Set WLANs (ESS) have multiple access points.
CCENT: FTP, port 20 and 21. SMTP, port 25. Telnet, port 23. HTTP, port 80. DNS, port 53. POP3, port 110. NNTP, port 119
CCNA Security / ISCW: An asterisk in SDM represents the ACL option "any".
CCNP / BSCI: If you have consecutive fields of zeroes, as that address does, they can be expressed with two colons.
It doesn't matter if you have two fields or eight, you can simply type two colons and that will represent all of the consecutive fields.
The key here is that you can only do this once in an IPv6 address. This is zero compression.
Original format: 1234:1234:0000:0000:0000:0000:3456:3434
Using zero compression: 1234:1234::3456:3434
CCNP / BCMSN: DAI is used on switches to fight man-in-the-middle attacks.
CCNP / ONT:
Sample the analog signal
Quantize that sample
Encode the signal
Compress the samples (optional, helps to conserve bandwidth)
