Port Security is typically implemented on _________ ports to restrict the number of valid MAC addresses.
- Access
- Dynamic
- EtherChannel
- Trunk
Port Security is typically implemented on Access ports to restrict the number of valid MAC addresses.
Which network topology features a central hub or switch where all nodes are connected, offering simplicity but creating a single point of failure?
- Bus
- Mesh
- Ring
- Star
In a star topology, all nodes are connected to a central hub or switch, providing simplicity but creating a single point of failure.
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.
A company's network often experiences changes in topology due to frequent addition and removal of devices. Which routing method should they primarily use?
- Default Routing
- Dynamic Routing
- Policy-Based Routing
- Static Routing
Dynamic Routing is the most appropriate for a network with frequent topology changes as it can adapt to changes automatically.
In ______, the active virtual gateway (AVG) assigns a virtual MAC address to each member of the GLBP group.
- HSRP
- GLBP
- VRRP
- OSPF
In GLBP (Gateway Load Balancing Protocol), the active virtual gateway (AVG) assigns a virtual MAC address to each member of the GLBP group.
________ is a technique used in BGP to filter out undesired routes.
- Prefix Filtering
- Route Aggregation
- Route Summarization
- Route Filtering
Route filtering is a technique used in BGP to filter out undesired routes.
