   Which benefit is directly associated with implementing high availability features in a service provider network?

   • AGuaranteed packet delivery with zero loss under all conditions
   • BImproved network security against external attacks
   • CReduced mean time to repair (MTTR) for hardware failures
   • DIncreased resilience to device or link failures, leading to higher service availability

   Which statement correctly describes a benefit of using redundant interfaces in a service provider network?

   • AThey provide a backup interface that can take over if the primary interface fails
   • BThey provide fast failure detection for routing protocols
   • CThey maintain routing protocol state during a switchover
   • DThey allow multiple physical links to be combined into a single logical link

   A network engineer is configuring link aggregation between two MX routers. The engineer wants to ensure that if one physical link fails, traffic continues to flow over the remaining links without requiring a routing protocol to reconverge. Which configuration is required?

   • AConfigure VRRP on the interface.
   • BConfigure an aggregated Ethernet (ae) interface with multiple member links.
   • CConfigure BFD on the interface.
   • DConfigure a redundant Ethernet (reth) interface with a single member link.

   Which statement correctly describes a benefit of NSR compared to graceful protocol restart (GR)?

   • ANSR does not require neighboring routers to support the feature
   • BNSR requires manual intervention to trigger the switchover
   • CNSR is only supported for BGP, not OSPF
   • DNSR requires neighboring routers to support the feature

   Which statement correctly describes a characteristic of BFD?

   • ABFD is only supported on physical interfaces, not logical interfaces
   • BBFD is a routing protocol that exchanges routes with neighbors
   • CBFD operates independently of routing protocols and can detect failures faster than protocol timers
   • DBFD requires a dedicated physical link between devices
