問題 #66
Which two statements are correct about tunnels? (Choose two.)
答案：A,D
解題說明：
For a tunnel to be established, the endpoints must have a route to each other. This is essential for the encapsulated packets to reach their destination.
Tunnels encapsulate packets, adding extra headers for the encapsulation protocol, which increases the overall packet size.
問題 #67
Which statement is true about the configuration shown in the exhibit?
答案：D
問題 #68
You have configured a GRE tunnel from your local router with tunnel source 10.0.0.1 to a remote router at destination 192.168.0.1. The tunnel is functioning until you commit set routing-options static route 0.0.0.0/0 next-hop gr-0/0/0. This configuration causes the tunnel to go down. Which statement is correct in this scenario?
答案：C
解題說明：
A GRE tunnel's outer, delivery-layer packets are forwarded using the router's ordinary underlay routing table, meaning the tunnel destination address (192.168.0.1 in this case) must itself be resolvable to a physical, non-tunnel next hop for the encapsulated packets to actually leave the router. Before this configuration change, the default route (or some more specific route) presumably pointed toward a real physical next hop, allowing the router to reach 192.168.0.1 and keep the tunnel operational. When the administrator commits a static default route of 0.0.0.0/0 with a next hop of gr-0/0/0, every destination lookup that previously fell back to the default route -- including the lookup for the tunnel's own destination address, 192.168.0.1, since no more specific route exists for it -- now recurses through the GRE interface itself. This creates a circular dependency: the router needs to route to 192.168.0.1 to keep the tunnel up, but the only route it has to reach 192.168.0.1 now points back into the tunnel that requires 192.168.0.1 to already be reachable, so the interface's next-hop resolution fails and the tunnel drops. This is an entirely valid and common GRE design pitfall rather than any platform restriction; GRE interfaces can be legitimately used as static route next hops, do not require loopback-sourced encapsulation, and do not require a /32 host route to resolve their destination, provided that route does not recursively point back through the tunnel.
問題 #69
A GRE tunnel is experiencing fragmentation issues. You confirm that the tunnel is up and is functioning correctly. You confirm that hosts are sending 1500-byte packets. In this scenario, which statement is correct?
答案：D
解題說明：
GRE encapsulation adds a fixed 24 bytes of overhead to every packet it carries -- 4 bytes for the GRE header itself and 20 bytes for the new outer IPv4 delivery header. When a host transmits a full 1500-byte Ethernet payload into a gr- interface, the resulting encapsulated packet becomes
1524 bytes, which exceeds the physical interface's standard 1500-byte MTU and forces fragmentation or drops if the don't-fragment bit is set. The correct remediation is to reduce the effective MTU seen by end hosts so that encapsulated packets never exceed the physical link's transmission limit. Junos automatically applies this logic to gr-logical interfaces, which default to a
1476-byte protocol MTU (1500 minus 24), but when the underlying physical interface or a manually configured path is involved, administrators must explicitly size the interface MTU to
1476 bytes to prevent post-encapsulation oversize packets. Allowing fragmentation with clear- dont-fragment is a workaround that increases CPU load and can degrade performance rather than solving the root cause, BFD addresses link-failure detection rather than MTU sizing, and ToS copying affects only the type-of-service byte, not packet length.
問題 #70
You are a network operator troubleshooting BGP connectivity.
Which two statements are correct about the output shown in the exhibit? (Choose two.)
答案：B,C
解題說明：
The local AS is 65400, as indicated by "Local AS: 65400".
The output shows "NLRI for this session: inet-unicast", which indicates that the routers are exchanging IPv4 unicast routes.
