Company XYZ asks for design recommendations for Layer 2 redundancy. The company wants to prioritize fast convergence and resiliency elements in the design. Which two technologies are recommended? (Choose two.)
A.
Use BPDU guard.
B.
Use UniDirectional Link Detection.
C.
Use root guard.
D.
Configure DHCP snooping on the switches.
E.
Design MLAG/MC-LAG into the network wherever possible.
The correct answers are B. Use UniDirectional Link Detection and E. Design MLAG/MC-LAG into the network wherever possible.
B. UniDirectional Link Detection (UDLD): This technology helps detect unidirectional links, which can cause issues like traffic loss and network instability. It enables fast detection and recovery from failures, improving resiliency and convergence.
E. Design MLAG/MC-LAG into the network wherever possible: Multi-chassis Link Aggregation (MLAG) or Multi-chassis Link Aggregation Group (MC-LAG) provides redundancy and load balancing between two physical devices. It ensures resiliency and faster convergence by preventing a single point of failure and improving network availability.
Both of these technologies are well-suited for prioritizing fast convergence and resiliency in a Layer 2 network design.
B, E are correct.
Unidirectional Link Detection (UDLD) is one of two major features (UDLD and loop guard) in Cisco Switches to prevent Layer 2 loops. In order to detect the unidirectional links before the forwarding loop is created, UDLD works by exchanging protocol packets between the neighboring devices.
BE.
Root Guard doesn't help election speed in any meaningful way. Its purpose is to protect from undesired switches from taking over root switch role.
UDLD helps with resiliency.
