質問 # 88
How many bytes of overhead does an IP-IP tunnel add to a packet?
正解：C
質問 # 89
A switch uses the factory-default storm control configuration. A sudden unknown-unicast burst causes packet loss for only 4-5 seconds before stabilizing. Which statement describes why normal operation resumes automatically?
正解：C
解説：
The factory-default storm control configuration on EX Series switches operates in a purely rate- limiting mode rather than an interface-shutdown mode. When broadcast, multicast, or unknown- unicast traffic on a port exceeds the configured bandwidth-percentage threshold, the default action is simply to police the offending traffic type and silently drop only the packets that exceed that threshold, while all traffic within the allowed rate continues to be forwarded normally and the interface itself remains administratively and operationally up throughout the event. This explains the observed symptom precisely: during the burst of unknown-unicast frames, the switch dropped the excess volume above the configured limit, producing a brief period of packet loss, but as soon as the burst subsided and traffic fell back under the threshold, storm control simply stopped dropping packets and normal forwarding resumed automatically -- no administrative shutdown, recovery timer, or manual intervention was ever involved, because the interface was never taken down in the first place. This default drop-only behavior is distinct from the optional interface- shutdown action, which must be explicitly configured if an administrator wants storm control to disable a port outright on violation (as seen in a related scenario requiring the clear ethernet- switching recovery-timeout command). Storm control by default covers broadcast, multicast, and unknown-unicast traffic types together, not multicast alone, and it has no functional relationship to GRES, which governs Routing Engine redundancy rather than Layer 2 traffic policing.
質問 # 90
You want to verify prefix information being sent from 10.36.1.4.
Which two statements are correct about the output shown in the exhibit? (Choose two.)
正解：C、D
解説：
The AS path attribute shows AS numbers (e.g., 65401 65520.), indicating the route's traversal through one or various autonomous systems.
The output displays the selected routes and the attributes with which they were received, but does not show the effects of import policy on the routing attributes.
Nothing indicates that the routes have been received from an IBGP peer. The asterisks only indicates whether the routes have been imported into the routing table (RIB) after the application of the import policies.

質問 # 91
Which two statements are correct about link aggregation? (Choose two.)
正解：B、C
質問 # 92
Which statement describes the additional overhead added when a packet is encapsulated in a GRE tunnel?
正解：A
解説：
A GRE-encapsulated packet consists of the original passenger packet wrapped inside a GRE header and a new outer IP delivery header, and the combined size of these two additions is what constitutes GRE's per-packet overhead. The base GRE header, as defined in RFC 2784 and used in its minimal, non-keyed, non-checksummed form (the default and most common deployment), is exactly 4 bytes in length, containing the flags/version field and the protocol type field identifying the encapsulated payload's ether type. Layered around that GRE header is a completely new outer IPv4 header, which itself consumes a standard 20 bytes, containing the tunnel source and destination addresses used for delivery across the underlying network. Adding these two components together -- 4 bytes for the GRE header plus 20 bytes for the new outer IPv4 header -- yields a total of exactly 24 bytes of overhead imposed on every encapsulated packet, which is precisely why Junos automatically sets the default protocol MTU on gr- tunnel interfaces to 1476 bytes (1500 minus 24) to prevent oversized, post-encapsulation packets from requiring fragmentation on a standard 1500-byte Ethernet path. The 20-byte figure alone describes only the new IP header in isolation and omits the GRE header itself, while 12 and 32 bytes do not correspond to any standard, non-keyed GRE encapsulation configuration and are included purely as plausible-looking distractors.
