SPOTTER NETWORK ACTUAL EXAM
SOLVED QUESTIONS COMPLETE
PREPARATION RESOURCE
●● CCNA Security
Answer: Cisco Certified Network Associate Security
●● What does TCP/IP stand for?
Answer: Transmission Control Protocol over Internet Protocol
●● What does UDP/IP stand for?
Answer: User Datagram Protocol over Internet Protocol
●● When is TCP/IP used?
Answer: TCP used primarily for establishing low-latency and loss
tolerating connections between applications on the Internet.
TCP has emerged as the dominant protocol used for the bulk of Internet
connectivity.
●● When is UDP/IP used?
,Answer: UDP provides 2 services not provided by the IP layer. Port
numbers to help distinguish different user requests and, checksum
capability to verify that the data arrived intact.
UDP just sends the packets, which means that it has much lower
bandwidth overhead and latency.
●● What OSI Model layer does Encryption happen at?
Answer: Layer 6: Presentation Layer
●● What OSI Model layer serves as the session manager?
Answer: Layer 5: Session Layer
Session Layer handles the creation, maintenance, and teardown of
communications channel (sessions) that exists between two
communicators.
●● What is the main purpose of the Transportation layer (Layer 4)?
Answer: The main purpose of the transportation layer (Layer 4) is to
establish a logical end-to-end connection between two systems. TCP/IP
and UDP/IP are used on this layer.
●● Name the devices on the Network Layer (Layer 3) and what do they
do.
, Answer: Routers and Layer 3 Switches (IP routing capabilities)
Determines the valid paths from here to there. It also determines of the
valid paths, which one is the lowest cost or best path to get there
●● What is the purpose of Layer 2 of the OSI Model, and what is it
called?
Answer: Data Link Layer (Layer 2)
Switches frames using the MAC Address
●● What does MAC Address stand for, and what are all of the names for
a MAC Address?
Answer: Media Access Control Address
- Hardware address
- Physical address
- Burned-in address
- Layer 2/L2 address
●● Physical layer is which layer in the OSI Model?
Answer: Layer 1: Physical Layer
Hubs, Repeaters, Cables, pins and connectors
