- 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 ______ 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.
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.
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 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.
What protocol is primarily used for network management and monitoring devices on IP networks?
- TCP
- UDP
- ICMP
- SNMP
SNMP (Simple Network Management Protocol) is primarily used for network management and monitoring devices on IP networks.
