For high-capacity data transmission within a metropolitan area, ________ is a preferred choice.
- Fiber Optics
- Satellite
- Coaxial Cable
- Microwave
For high-capacity data transmission within a metropolitan area, Fiber Optics is a preferred choice due to its high bandwidth and low signal loss.
In the context of advanced firewall configuration, what is deep packet inspection (DPI)?
- A method to analyze and filter the actual content of data packets at the application layer
- A technique to quickly route packets based on their source and destination addresses
- A process of encrypting packet headers for enhanced security
- A mechanism to reduce latency by inspecting only packet headers
Deep packet inspection (DPI) involves analyzing and filtering the actual content of data packets at the application layer, providing advanced security capabilities.
What is the impact of having a large number of OSPF areas on network performance?
- Enhances network performance by reducing the size of the OSPF database and shortening SPF calculation times.
- Has no impact on network performance as OSPF is designed to efficiently handle a large number of areas.
- Improves network scalability, but at the cost of increased routing table size.
- May degrade network performance due to increased LSA propagation and SPF computation overhead.
A large number of OSPF areas can impact network performance by increasing LSA propagation and SPF computation overhead, potentially leading to degradation.
________ mechanisms in QoS help to avoid packet loss during high traffic periods by temporarily storing excess packets.
- Congestion Avoidance
- Traffic Shaping
- Packet Sniffing
- Bandwidth Policing
Congestion Avoidance mechanisms in QoS help to avoid packet loss during high traffic periods by temporarily storing excess packets.
When a company is merging with another and needs to integrate their networks without redesigning IP addressing, which tunneling method is often used to simplify this process?
- IPsec
- L2TP
- MPLS
- GRE
GRE (Generic Routing Encapsulation) tunneling is often used when merging networks to integrate them without redesigning IP addressing, simplifying the integration process.
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 does a ring topology manage the data collision and ensure efficient data transmission?
- Collision Detection
- Frequency Division Multiplexing
- Time Division Multiplexing
- Token Passing
In a ring topology, token passing is used to manage data collisions and ensure efficient data transmission. Only the device with the token can transmit data at any given time.
Chassis aggregation is mainly used to improve what aspect of network performance?
- Bandwidth
- Latency
- Reliability
- Security
Chassis aggregation is mainly used to improve bandwidth in a network, combining the capacity of multiple physical devices.
What is the significance of the 'native VLAN' on a trunk port?
- It carries only management traffic
- It is reserved for high-priority data
- It is the default VLAN for untagged traffic on the trunk
- It is used for voice traffic
The native VLAN on a trunk port is the default VLAN for untagged traffic, facilitating communication between devices that do not understand VLAN tagging.
