Part 4.3

Which of the following actions best demonstrates device hardening on a network switch?

• Installing additional RAM modules

• Disabling unused ports and services

• Increasing the screen brightness

• Changing the device’s color

A network administrator is setting up a new router. Which step should they take to improve security during initial configuration?

• Leave the default password unchanged

• Change the default password to a strong, unique one

• Share the default password with all users

• Disable all network interfaces

How does enabling port security on a switch help protect the network?

• It increases the speed of data transmission

• It restricts access to the network based on device MAC addresses

• It allows unlimited devices to connect to each port

• It disables all ports by default

When implementing 802.1X authentication, what is the primary benefit for network security?

• It allows any device to connect without credentials

• It authenticates devices before granting network access

• It increases wireless signal strength

• It disables encryption on the network

Which of the following is an example of a MAC filtering strategy?

• Allowing only devices with specific MAC addresses to connect

• Assigning static IP addresses to all devices

• Using only wireless connections

• Disabling DHCP on the network

A company wants to prevent unauthorized devices from connecting to its network. Which network access control method should they implement?

• Port security

• Open Wi-Fi access

• Disabling all firewalls

• Using default device settings

What is the purpose of using an Access Control List (ACL) on a router?

• To filter network traffic based on defined rules

• To increase the router’s processing speed

• To automatically update firmware

• To provide wireless connectivity

How does content filtering contribute to network security?

• By blocking access to inappropriate or malicious websites

• By increasing network bandwidth

• By allowing all traffic through the firewall

• By disabling encryption

Which of the following best describes a screened subnet (DMZ) in network security?

• A subnet that is completely isolated from all networks

• A subnet that separates trusted and untrusted networks to provide an additional security layer

• A subnet used only for wireless devices

• A subnet with no security controls

If a network administrator wants to allow only certain users to access a specific resource, which security rule should they implement?

• Access Control List (ACL)

• Open access policy

• Default password policy

• Disable all user accounts
