How does a next-generation firewall (NGFW) enhance network security compared to traditional firewalls?
- NGFW integrates intrusion prevention, application awareness, and other advanced features for more comprehensive protection
- Traditional firewalls have faster throughput compared to NGFW
- NGFW relies solely on packet filtering, which is more efficient than traditional methods
- Traditional firewalls are more scalable and adaptable to evolving threats
Next-generation firewalls (NGFW) enhance network security by integrating intrusion prevention, application awareness, and other advanced features for more comprehensive protection compared to traditional firewalls.
An ISP needs to control network congestion during peak hours. What QoS strategy should they employ to manage bandwidth usage effectively?
- Weighted Random Early Detection (WRED)
- Traffic Policing
- Class-Based Weighted Fair Queuing (CBWFQ)
- Congestion Avoidance
Weighted Random Early Detection (WRED) is a congestion avoidance technique that an ISP can use to control network congestion during peak hours.
The election of the master virtual router in _______ is based on the priority configured on the routers participating in the VRRP group.
- HSRP
- GLBP
- VRRP
- OSPF
In VRRP (Virtual Router Redundancy Protocol), the election of the master virtual router is based on the priority configured on the routers participating in the VRRP group.

PPP is primarily used for establishing a direct connection between two nodes in Wide Area Network (WAN) configurations.
What is the process called when a DHCP server assigns a permanent IP address to a client?
- Address Reservation
- Lease Extension
- Static Allocation
- Dynamic Allocation
The process of a DHCP server assigning a permanent IP address to a client is known as Static Allocation.
What is the purpose of using split tunneling in a VPN configuration?
- To tunnel only a specific subset of traffic through the VPN, allowing direct access to other resources.
- To tunnel all traffic through the VPN, regardless of the destination.
- To create a secure tunnel between two VPN gateways.
- To establish a secure connection between a VPN client and server.
Split tunneling in a VPN configuration allows tunneling only a specific subset of traffic through the VPN, providing direct access to other resources.
