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