COMPLETE ACCURATE EXAM
QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100% CORRECT
ANSWERS) /ALREADY GRADED A+
What's the purpose of poisoned reverse and how
does it work? - ....ANSWER...Prevents count to
infinity loops by increasing cost
What is OSPF? - ....ANSWER...Open Shortest Path
First
OSPF is a link state technology that uses Dijkstra
algorithm to compute routing
Open - publicly available
What is the protocol used by all AS's for intra AS
routing on the internet? - ....ANSWER...Open Shortest
Path First (OSPF)
Intermediate System to Intermediate System (IS-IS)
Routing Information Protocol (RIP)
, What is the structure data management language
used by YANG? - ....ANSWER...XML
How are network layer datagrams encapsulated
before being placed on the link layer? -
....ANSWER...Frames, put in an envelope
(encapsulation) and stamp it (headers) with the
destination and source address
Purpose of EDC - ....ANSWER...Error detection and
correction
Predominant method of error-detection in the link
layer: - ....ANSWER...Checksums
One dimensional parity checks - even or odd bits
cyclic redundancy check (CRC) - XORs bits together,
divides them with a known quantity, an agreed upon
value, 1011, and if that division ends with a remainder
you know you have an error
3 random access MAC protocols -
....ANSWER...Slotted Aloha, pure(unslotted) Aloha,
CSMA/CD
