ExplanationDMZ is a segregated network zone for hosting public-facing services, enhancing security.
#4
In the context of router security, what is the primary purpose of conducting regular security audits?
To identify and address security vulnerabilities
ExplanationAudits help identify and address security vulnerabilities in router configurations.
#5
What is the significance of securing the physical access to a router?
To prevent unauthorized physical tampering
ExplanationPhysical security prevents unauthorized physical access and tampering to enhance overall router security.
#6
Which protocol is commonly used for securing the management access to a router?
SSH
ExplanationSecure Shell is commonly used for securing access to router management interfaces.
#7
What does NAT stand for in the context of router security?
Network Address Translation
ExplanationNAT is used to translate private IP addresses to a public one for enhanced security.
#8
Which of the following is a common method to protect against DoS (Denial of Service) attacks on a router?
Enabling QoS (Quality of Service)
ExplanationQuality of Service helps protect against DoS attacks by prioritizing traffic.
#9
What is the purpose of VLANs (Virtual Local Area Networks) in router security?
To segment and isolate network traffic
ExplanationVLANs segregate traffic for enhanced security by isolating network segments.
#10
Which security measure involves changing the default port number for router management access?
Port Security
ExplanationChanging the port number for management access enhances security.
#11
What does the acronym ACL stand for in the context of router security?
Access Control List
ExplanationACLs control access to router resources by defining permission rules.
#12
What is the role of intrusion detection systems (IDS) in router security?
To detect and respond to suspicious activities
ExplanationIDSs identify and respond to potential security threats by monitoring router activity.
#13
Which security feature helps prevent unauthorized access by filtering traffic based on IP addresses?
Firewall
ExplanationFirewalls restrict unauthorized access by filtering traffic based on IP addresses.
#14
What is the purpose of disabling unnecessary services on a router?
To improve performance
ExplanationDisabling services enhances router performance by reducing unnecessary overhead.
#15
What is the main advantage of using a VPN (Virtual Private Network) in router configurations?

ExplanationVPNs provide heightened security through encrypted communication.
#16
Why is it important to regularly update the firmware of a router?
To improve security and fix vulnerabilities
ExplanationRegular updates enhance security and address potential vulnerabilities in router firmware.
#17
Why is it advisable to disable unnecessary router services such as UPnP (Universal Plug and Play)?
To reduce the attack surface
ExplanationDisabling UPnP minimizes the router's vulnerability by reducing potential entry points for attacks.
#18
What is the primary purpose of using strong encryption protocols for router communications?
To protect against eavesdropping and unauthorized access
ExplanationEncryption ensures secure communication by preventing unauthorized access and eavesdropping.
#19
What is the purpose of implementing role-based access control (RBAC) on a router?
To limit access based on user roles and responsibilities
ExplanationRole-Based Access Control restricts access based on predefined roles and responsibilities.
