Network Redundancy Protocols and Configurations

The video tutorial explains redundant systems, focusing on active-passive and active-active configurations. It covers the setup and challenges of these configurations, including data flow management and synchronization. The tutorial also discusses diverse paths in data centers for redundancy and introduces redundancy protocols like FHRP and VRRP to maintain network uptime and availability.

What is the primary role of the passive device in an active-passive configuration?

• To provide additional processing power

• To monitor the active device and take over if it fails

• To actively process data

• To act as a backup for data storage

In an active-active configuration, what is a key challenge?

• Keeping one device offline at all times

• Synchronizing configurations only once a day

• Managing data flows in multiple directions

• Ensuring both devices are never operational at the same time

Why might an organization choose an active-active configuration over an active-passive one?

• To reduce the number of devices needed

• To ensure only one device is ever active

• To increase the complexity of the network

• To utilize both devices simultaneously for better performance

What is a benefit of having multiple paths in a data center?

• It reduces the need for dynamic routing protocols

• It allows for continuous connectivity even if one path fails

• It eliminates the need for firewalls

• It simplifies network management

What must be considered when implementing diverse paths to multiple ISPs?

• The physical location of the ISPs

• Dynamic routing protocols and failover processes

• The cost of each ISP

• The color of the network cables

What is the purpose of the First Hop Redundancy Protocol (FHRP)?

• To encrypt data between routers

• To increase the speed of data transmission

• To allow multiple routers to share a single IP address as the default gateway

• To provide a backup power supply

How does the Virtual Router Redundancy Protocol (VRRP) maintain network uptime?

• By moving a virtual IP address to a different router if the current one fails

• By using a single router for all traffic

• By shutting down the network temporarily

• By increasing the bandwidth of the existing router

What happens if the default gateway fails in a network using FHRP?

• The network speed decreases

• All data is lost

• Another router takes over the IP configuration

• The network shuts down

Which protocol allows a virtual IP address to be associated with multiple routers?

• Internet Control Message Protocol (ICMP)

• Simple Network Management Protocol (SNMP)

• Virtual Router Redundancy Protocol (VRRP)

• Dynamic Host Configuration Protocol (DHCP)

What is a key advantage of using redundancy protocols like FHRP and VRRP?

• They increase the cost of network maintenance

• They reduce the need for network security

• They allow for hardware changes without downtime

• They eliminate the need for routers
