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 (Point-to-Point Protocol) is primarily used for establishing a direct connection between two nodes in what type of network configurations?
- LAN
- WAN
- MAN
- PAN
PPP is primarily used for establishing a direct connection between two nodes in Wide Area Network (WAN) configurations.
What is the significance of the Network Interface Layer in the TCP/IP model in relation to OSI's Data Link Layer?
- Handles flow control between devices on the same network
- Manages error detection and correction
- Provides a reliable and error-free link between two directly connected nodes
- Responsible for logical addressing using MAC addresses
The Network Interface Layer in the TCP/IP model is significant as it is responsible for logical addressing using MAC addresses, akin to the OSI Data Link Layer.
A company is experiencing poor audio quality in their VoIP calls during peak hours. Which QoS mechanism should be implemented to resolve this issue?
- Traffic Policing
- Traffic Shaping
- Prioritization using DiffServ
- Weighted Fair Queuing (WFQ)
Prioritization using Differentiated Services (DiffServ) allows for the classification and prioritization of traffic, which is essential for improving VoIP quality during peak hours.
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.
