질문 # 73
Which statement is correct about IP-IP tunnels?
정답：C
설명：
"The ENCAPSULATOR does not change the inner IP header, except to decrement the TTL and it remains unchanged during its deliver to the endpoint" - only router that encapsulates the inner packet decrements its TTL - during transit, the inner packet is unchanged.
질문 # 74
Which two statements about DHCP snooping are correct? (Choose two.)
정답：A,C
질문 # 75
Which two statements are true about routing instances on Junos devices? (Choose two.)
정답：A,D
설명：
The virtual-router routing-instance type in Junos is a general-purpose instance type intended for creating isolated, independent routing and forwarding contexts within a single physical device for applications that have nothing to do with MPLS-based VPN services - common use cases include multi-tenant network segmentation, filter-based forwarding deployments, and simple traffic isolation between departments or customers on a shared switch or router, all of which are non-VPN-related applications by nature. Layer 2 and Layer 3 VPN services, by contrast, rely on a different, dedicated routing-instance type specifically named vrf, which integrates with MPLS/BGP-based VPN signaling, route distinguishers, route targets, and PE-CE routing exchange; virtual-router instances do not participate in that VPN signaling framework at all, which is why the statement associating virtual-router with VPN use is incorrect. Whenever an administrator creates any user-configured routing instance - regardless of its specific type - Junos automatically allocates and generates a brand-new, dedicated routing table for that instance, named according to the pattern instance- name.inet.0 (or the appropriate address-family suffix), which is entirely separate from and independent of the default master inet.0 table used by the global/default routing context. Because each new routing instance receives its own distinct table rather than sharing or defaulting into the master inet.0 table, the statement claiming instances automatically fall back to using inet.0 unless configured otherwise is factually incorrect; instances are isolated by design from the outset. Reference topics: Junos Enterprise Routing - Protocol Independent Routing, Routing Instance Types and Table Allocation.
질문 # 76
Which statement describes how nonstop active routing (NSR) maintains routing protocol information during a Routing Engine switchover?
정답：C
설명：
Nonstop active routing's defining architectural feature is that the backup Routing Engine runs a fully live, active instance of the routing protocol daemon (rpd) in parallel with the primary Routing Engine's rpd instance, continuously, from the moment NSR and its prerequisite GRES are established - not merely at the instant a switchover begins. As protocol adjacencies form, routes are learned, and the RIB is updated on the primary Routing Engine, that same protocol and RIB state is mirrored in real time to the backup Routing Engine's rpd process through an internal synchronization mechanism, so the backup's protocol state remains a live, up-to-date replica of the primary's at essentially every moment during normal operation. When a switchover occurs, the backup Routing Engine simply assumes the primary role with protocol adjacencies, routing tables, and forwarding state already fully populated and current, allowing it to continue operating without re-establishing neighbor relationships or re-learning the network topology, which is what makes the switchover genuinely nonstop and invisible to neighboring routers. This is fundamentally different from graceful restart, where the restarting router must rebuild its state by requesting help from cooperating neighbors after the fact. The Packet Forwarding Engine plays no role in synchronizing protocol-layer information such as LSAs or BGP updates; that is strictly an rpd-to-rpd function coordinated through the Routing Engine synchronization infrastructure. Reference topics: Junos Enterprise Routing - High Availability, Nonstop Active Routing Architecture and rpd Synchronization.
