WGU D315 CORRECT FINAL EXAM QUESTIONS
AND ANSWERS SURE A+
✔✔Name the 3 CIA triades - ✔✔Integrity, Availability and Confidentiality
✔✔What is the CIA Triade Integrity? - ✔✔Detects alteration in storage, transit and
process
✔✔What is the CIA Triade Availability? - ✔✔Ensure Authorized Access, Performance
and Backup
Keeping unauthorized users out is not in this triade.
✔✔What is the CIA Triade Confidentiality? - ✔✔Protect from unauthorized access and
use, protecting data access in storage, transit and process
✔✔100m long Cat 5 cable supports speeds up to - ✔✔100 Mb/s
✔✔100m long Cat 5e cable supports speeds up to - ✔✔1000 Mb/s or 1 Gb/s
✔✔100m long Cat 6 cable supports speeds up to - ✔✔10 Gb/s
✔✔100m long Cat 6a cable supports speeds up to - ✔✔10 Gb/s
, ✔✔Does a firewall provide two way protection? - ✔✔Yes, it protects ingress and egress
data
✔✔Firewall that only checks the address label - ✔✔Packet Filter
✔✔On what OSI level is a Packet Filter operating - ✔✔Transport (checks TCP/UDP prot
numbers) and Network (checks source and destination IP)
✔✔What is a circuit level gateway - ✔✔A firewall that conceals the true identity of the
protected network (hides IP) on the transport (4) layer
✔✔What does state in stateful mean? - ✔✔It refers to the connection state between two
computers
✔✔Why do we need the 5th layer on a Stateful Inspection - ✔✔In this connection, the
firewall is creating temporary rules per session to permit communication (TCP) back to
the sender.
✔✔What is a stateful inspection - ✔✔It reduces the amount of firewall rules. Firewall
vendors implemented a feature that only needs one rule to allow the initial
communication.
✔✔How do we protect the application level with a firewall - ✔✔With a proxy server,
Middle man or Layer 7 firewall
✔✔Can a packet filter firewall scan the packet content? - ✔✔No, a layer 7 or proxy is
needed
✔✔What is a IDS - ✔✔Intrusion Detection system. A system for detecting attempting
intrusion. Related to intrusion prevention systems (IPS) that block suspected attacks
✔✔What is IPS - ✔✔Intrusion Prevention System that can block traffic if a malicious
anomaly is detected
✔✔Cyber Attack - Ransomware - ✔✔Encrypts data. Attacker sells the key. Prevent with
Virus scanner
✔✔Cyber Attack - Man in the Middle - ✔✔Eaves dropping. The data flows thru the
middle man. The attacker can stop/change the data
✔✔Cyber Attack - Zero Day exploit - ✔✔New unheard vulnerability. Needs to be
patched
