Unified Threat Management

Multiple Choice

This type of firewall is specifically designed for network security, often found in corporate environments.

• packet filtering firewall
• standalone network firewall

• host-based firewall
• application firewall

Multiple Choice

This type of firewall provides basic home and small office protection and is found on a router.

• Software firewall
• Router firewall
• Hardware firewall
• Application firewall

Multiple Choice

An example of a OS based firewall is

• Windows Firewall
• Application Firewall
• Linux Firewall
• Router Firewall

Multiple Choice

This type of firewall is an all-in-one security appliances that include firewall capabilities along with anti-virus, anti-spam, and intrusion detection systems.

• Unified Threat Management (UTM)
• Proxy Server
• Virtual Private Network (VPN)
• Network Address Translation (NAT)

Multiple Choice

What is packet filtering?

• Packet filtering is a method of controlling network traffic by allowing or blocking packets based on defined security rules.
• Packet filtering is a technique for encrypting data during transmission.
• Packet filtering is a method for compressing network traffic to save bandwidth.
• Packet filtering is a way to monitor user activity on a network.

Multiple Choice

Stateful inspection is more detailed than packet filtering because

• Stateful inspection only checks the header of packets.
• Packet filtering is more secure than stateful inspection.
• Stateful inspection considers the state of connections, making it more detailed than packet filtering.
• Stateful inspection does not track connection states.

Multiple Choice

Stateful inspection is more commonly found in what type of environment?

• Network environments

• Cloud environments
• Web applications
• Corporate Network environments

Multiple Choice

Unlike packet filtering which examines data at the packet level according to rules, what does stateful inspection review to consider its level of protection?

• secure TCP handshake session

• packet level data

• secure data on the transport level

• handshakes within the application layer

Multiple Choice

Which is better: packet filtering or stateful inspection?

• Stateful inspection is outdated.
• Stateful inspection is better.
• Packet filtering is more secure.
• Packet filtering is faster than stateful inspection.

Multiple Choice

What does the word hierarchical mean?

• Organized in a ranked order.

• Relating to a network of connections
• A method of sorting data randomly
• Describing a flat structure without levels

Multiple Choice

A network tree topology can be described as

• A linear connection of devices in a single path.
• A random arrangement of devices with no specific structure.
• A circular layout where each device connects to two others.
• A hierarchical structure connecting multiple devices in a branching manner.

Multiple Choice
