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.
How does dynamic routing differ from static routing in terms of scalability in a growing network?
- Both dynamic and static routing have similar scalability in a growing network.
- Dynamic routing is more scalable as it adapts to changes in the network, while static routing becomes impractical in a large and dynamic environment.
- Scalability is not a consideration in routing protocols.
- Static routing is more scalable as it allows for easy management of routes, while dynamic routing may become complex and less scalable as the network grows.
Dynamic routing is more scalable in a growing network as it can adapt to changes, making it suitable for larger and dynamic environments.
________ is a secure alternative to Telnet for accessing command-line interfaces on network devices.
- SSH
- SNMP
- SMTP
- HTTPS
SSH (Secure Shell) is a secure alternative to Telnet for accessing command-line interfaces on network devices.
In setting up a small office network, which device would be the most cost-effective for connecting multiple PCs while ensuring basic connectivity?
- Bridge
- Hub
- Router
- Switch
A hub is the most cost-effective device for connecting multiple PCs in a small office network, ensuring basic connectivity without advanced features.
The ________ layer of the OSI model ensures data integrity and error recovery at the transport level.
- Data Link
- Network
- Physical
- Transport
The Transport layer of the OSI model ensures data integrity and error recovery at the transport level.
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.
