A service provider operates a pair of MX960 routers as a core gateway. The network engineer wants to ensure that when the Routing Engine (RE) fails over, the forwarding plane continues to forward transit traffic without interruption, and that OSPF adjacencies remain up. The engineer has already configured GRES. What additional configuration is required to meet both requirements?

Configure a redundant Ethernet (reth) interface for the transit links.

Enable nonstop bridging (NSB) on the transit interfaces.

Enable graceful protocol restart (GR) for OSPF.

Enable NSR on the routing protocols.

What is the primary purpose of a link aggregation group (LAG) in a service provider network?

To provide gateway redundancy for end devices

To detect failures in forwarding paths quickly

To maintain routing protocol state during a switchover

To combine multiple physical links into a single logical link for increased bandwidth and redundancy

What is the primary purpose of Virtual Router Redundancy Protocol (VRRP) in a service provider network?

To maintain routing protocol state during a switchover

To detect failures in forwarding paths quickly

To combine multiple physical links into a single logical link

To provide gateway redundancy for end devices

What is the primary purpose of Graceful Protocol Restart (GR) on Juniper devices?

To enable continuous forwarding of traffic during a Routing Engine switchover

To provide fast failure detection for neighboring routers

To preserve Layer 2 bridging state during a Routing Engine switchover

To minimize disruption to routing protocols during a restart

What is the primary purpose of Graceful Routing Engine Switchover (GRES) on Juniper devices?

To maintain routing protocol state during a Routing Engine switchover

To preserve Layer 2 bridging state during a Routing Engine switchover

To provide fast failure detection for neighboring routers

To enable continuous forwarding of traffic during a Routing Engine switchover
