Which OSI layer is related to the IP protocol - Answer -Network 3
Which OSI layer is organizing the bits over the physical layer between devices in the
same collision domain? - Answer -Data Link 2 - They are in the same Frame
Which OSI layer is a Switch at? - Answer -Data Link 2
Which OSI layer is a WAP (Wireless Access Point) at? - Answer -Data Link 2
Which OSI layer is a router at - Answer -Network (3)
TCP protocol is on what OSI layer - Answer -Transport (4)
OSI layer 1 - Answer -Physical Layer (Cable, Hubs, Repeaters)
OSI layer 2 - Answer -Data Link Layer (Frame, Switch, PPP, Ethernet)
OSI layer 3 - Answer -Network Layer (Moves packets, IP)
OSI layer 4 - Answer -Transport Layer (TCP, end to end connection)
OSI Layer 5 - Answer -Session Layer (API, Sockets, Synch and send to port)
OSI layer 6 - Answer -Presentation layer (Syntax and encryption layer, SSL, SSH,
JPEG)
OSI layer 7 - Answer -Application layer (end user layer, http, applications)
Network Typology point to point - Answer -Two devices connect directly
Network Typology bus - Answer -All devices connect to a central main line
Network Typology Ring - Answer -All devices have two connections and form an
endless ring
Network Typology Star - Answer -All devices connect to a central point
Network Typology Tree - Answer -Multiple devices connect together (on a switch) and
then the switches are connected with each other
Network Typology Mesh - Answer -All devices connect directly to each other
Network Typology Hybrid - Answer -Multiple Network Typology within the network
, Cloud - where do I manage the OS Iaas or Paas? - Answer -Iaas
What do I manage on Paas (2) - Answer -Application and Data
Name the 3 CIA triades - Answer -Integrity, Availability and Confidentiality
What is the CIA Triade Integrity? - Answer -Detects alteration in storage, transit and
process
What is the CIA Triade Availability? - Answer -Ensure Authorized Access, Performance
and Backup
Keeping unauthorized users out is not in this triade.
What is the CIA Triade Confidentiality? - Answer -Protect from unauthorized access
and use, protecting data access in storage, transit and process
100m long Cat 5 cable supports speeds up to - Answer -100 Mb/s
100m long Cat 5e cable supports speeds up to - Answer -1000 Mb/s or 1 Gb/s
100m long Cat 6 cable supports speeds up to - Answer -10 Gb/s
100m long Cat 6a cable supports speeds up to - Answer -10 Gb/s
Does a firewall provide two way protection? - Answer -Yes, it protects ingress and
egress data
Firewall that only checks the address label - Answer -Packet Filter
On what OSI level is a Packet Filter operating - Answer -Transport (checks TCP/UDP
prot numbers) and Network (checks source and destination IP)
What is a circuit level gateway - Answer -A firewall that conceals the true identity of the
protected network (hides IP) on the transport (4) layer
What does state in stateful mean? - Answer -It refers to the connection state between
two computers
Why do we need the 5th layer on a Stateful Inspection - Answer -In this connection, the
firewall is creating temporary rules per session to permit communication (TCP) back to
the sender.
What is a stateful inspection - Answer -It reduces the amount of firewall rules. Firewall
vendors implemented a feature that only needs one rule to allow the initial
communication.
