The technique of _________ can help in optimizing the performance of a network by reducing the number of individual routes advertised.
- BGP
- OSPF
- Route Redistribution
- Route Summarization
The technique of route summarization can help optimize network performance by reducing the number of individual routes advertised, leading to more efficient routing tables.
In a network setup, which device is used to filter and forward packets between LAN segments based on MAC addresses?
- Bridge
- Hub
- Router
- Switch
A bridge is used to filter and forward packets between LAN segments based on MAC addresses in a network setup.
What is the difference between a site-to-site VPN and a remote access VPN?
- Site-to-Site VPNs connect entire networks, while Remote Access VPNs connect individual users to a network.
- Site-to-Site VPNs use SSL/TLS encryption, while Remote Access VPNs use IPSec.
- Site-to-Site VPNs are only suitable for small organizations, while Remote Access VPNs are suitable for large enterprises.
- Site-to-Site VPNs are always faster than Remote Access VPNs.
A site-to-site VPN connects entire networks, allowing multiple users to access the network, while a remote access VPN connects individual users to a network.
How does SD-WAN technology enhance WAN performance and reliability?
- By using traditional routing protocols
- By leveraging multiple WAN connections intelligently
- By increasing bandwidth on a single connection
- By prioritizing all traffic equally
SD-WAN enhances WAN performance and reliability by intelligently leveraging multiple WAN connections, optimizing traffic flow, and providing efficient use of resources.
DNS _________ is a technique used to distribute DNS load and increase reliability.
- Round Robin
- Load Balancing
- Failover
- Caching
DNS Load Balancing is a technique used to distribute DNS load and increase reliability. It involves distributing incoming DNS requests across multiple servers.
How does GLBP avoid the need for each host in the network to be configured with multiple gateway IP addresses?
- Virtual MAC Address
- Load Balancing
- Priority Value
- Preemption
GLBP uses load balancing to distribute traffic across multiple routers. Each host in the network only needs to be configured with a single virtual IP address.
In a ______ topology, each node cooperates in the distribution of data in the network.
- Bus
- Hybrid
- Mesh
- Ring
In a Hybrid topology, each node cooperates in the distribution of data in the network, combining features of different topologies.
Which cloud service model provides users with a platform to develop, run, and manage applications without the complexity of building and maintaining the infrastructure?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
Platform as a Service (PaaS) provides users with a platform to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
In a network, which device operates at the data link layer and is used to divide a network into segments?
- Bridge
- Hub
- Router
- Switch
A bridge operates at the data link layer and is used to divide a network into segments, controlling traffic between them.
What is the primary purpose of using VLANs in a network?
- Enhanced Network Performance
- Improved Physical Security
- Isolation of Broadcast Domains
- Simplified Network Management
VLANs improve network performance and security by isolating broadcast domains, reducing broadcast traffic and enhancing network segmentation.
