In DHCP, what is the purpose of the lease time?
- To specify the client's hardware address
- To determine the subnet mask
- To define the period a client can use an IP address
- To assign a default gateway
The lease time in DHCP defines the period during which a client can use the assigned IP address before renewal is required.
Which feature of SDN allows for the creation of virtual networks over the physical network infrastructure?
- Network Virtualization
- OpenFlow
- SDN Controller
- Traffic Engineering
Network virtualization in SDN enables the creation of virtual networks over the physical network infrastructure.
________ computing involves abstracting the underlying infrastructure in a way that allows software containers to deploy and run consistently across various computing environments.
- Edge
- Container
- Quantum
- Fog
Container computing involves abstracting the underlying infrastructure to enable software containers to deploy and run consistently across various computing environments.
What happens when a switch receives a frame on a trunk port without a VLAN tag?
- The frame is dropped
- The switch assigns a default VLAN
- The switch forwards the frame to all VLANs
- The switch sends a VLAN membership request
When a switch receives a frame on a trunk port without a VLAN tag, the switch assigns a default VLAN to the frame.
Which protocol uses the DUAL algorithm to ensure loop-free and rapid convergence?
- BGP
- EIGRP
- OSPF
- RIP
EIGRP (Enhanced Interior Gateway Routing Protocol) uses the DUAL (Diffusing Update Algorithm) to ensure loop-free and rapid convergence in routing.
_________ enables dynamic, programmatically efficient network configuration in SDN to improve network performance and monitoring.
- OpenFlow
- REST API
- Python scripting
- NETCONF
OpenFlow enables dynamic, programmatically efficient network configuration in SDN to improve network performance and monitoring.
A non-root bridge port that is selected to forward traffic towards the root bridge is called a _______ port.
- Blocking Port
- Designated Port
- Listening Port
- Root Port
A non-root bridge port that is selected to forward traffic towards the root bridge is called a Root Port. The Root Port offers the shortest path to the root bridge.
How does STP's root bridge election process determine which switch will be the root bridge in a network?
- Highest IP Address
- Highest MAC Address
- Lowest IP Address
- Lowest MAC Address
The root bridge is determined in the STP election process based on the switch with the lowest Bridge ID, which includes the priority and MAC address.
GRE tunnels are often used in conjunction with _______ to provide a more secure VPN solution.
- IPsec
- SSL/TLS
- PPTP
- L2TP
GRE tunnels are often used in conjunction with IPsec to provide a more secure VPN solution.
What is the primary benefit of using microservices architecture in cloud-based applications?
- Improved scalability, flexibility, and easier maintenance
- Reduced reliance on cloud services
- Simplified monolithic application structure
- Enhanced security through centralized control
The primary benefit of using microservices architecture in cloud-based applications is improved scalability, flexibility, and easier maintenance, as it allows for the independent development and deployment of services.
