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.
In a network using multiple routing protocols, _________ is used to facilitate communication between different network segments.
- BGP
- OSPF
- Route Redistribution
- Route Summarization
In a network with multiple routing protocols, route redistribution is used to facilitate communication between different network segments by sharing routes between protocols.
How do switches handle broadcast traffic in a network?
- Switches drop broadcast traffic
- Switches encapsulate broadcast traffic in VLAN headers
- Switches filter broadcast traffic based on MAC addresses
- Switches forward broadcast traffic to all ports
Switches forward broadcast traffic to all ports within a network. This ensures that broadcast messages reach all devices connected to the switch.
What is the primary purpose of an Access Control List (ACL) in network security?
- Assigning IP Addresses
- Filtering Network Traffic
- Regulating Network Speed
- Securing Physical Access
The primary purpose of an Access Control List (ACL) in network security is to filter network traffic based on specified criteria.
The process of _______ is used in RIP to prevent routing loops by setting a limit on the number of hops a packet can travel.
- Poison Reverse
- Route Poisoning
- Route Summarization
- Split Horizon
The process of Route Poisoning is used in RIP to prevent routing loops by setting a limit on the number of hops a packet can travel.
For a global organization, what IPv6 feature should be prioritized to manage large-scale address assignments and simplify network administration?
- Anycast
- Multicast
- Unique Local Addresses (ULA)
- Provider Independent (PI) Addressing
For a global organization managing large-scale address assignments, prioritizing Provider Independent (PI) Addressing in IPv6 simplifies network administration and enhances address flexibility.
