질문 # 89
You are verifying a new BGP peering session with an ISP. You issue the show bgp summary command, but the output shows the peer in the Active state. Which statement is correct in this scenario?
정답：C
설명：
The BGP finite state machine defined in RFC 4271 progresses through Idle, Connect, Active, OpenSent, OpenConfirm, and finally Established. The Active state is entered either directly after Idle, when the local router begins retrying a TCP connection setup toward the configured peer, or after a previous Connect attempt has failed and the ConnectRetry timer has expired, prompting the router to keep trying to complete the underlying TCP three-way handshake. Seeing a peer parked in Active therefore means the local device has a fully valid neighbor configuration and is persistently attempting to reach the remote address on TCP port 179, but the handshake is not succeeding -- common root causes include a firewall or ACL blocking TCP 179 between the two endpoints, an unreachable or incorrect peer IP address, the remote BGP process not running or not listening, or an asymmetric routing path preventing the SYN/ACK from returning. It does not indicate a misconfiguration on the local box in the sense of a missing statement (that would typically leave the session as Idle), nor does it indicate an established, functioning session exchanging UPDATE messages (that state is Established), and it is not a deliberately idle/disabled condition, which Junos reports plainly as Idle. Recognizing Active as 'trying to connect' rather than 'connected' is essential for correct BGP troubleshooting sequencing.

Referring to the output shown in the exhibit, which statement is correct?
정답：A
질문 # 91
Which statement is correct about the exhibit?
정답：C
질문 # 92
You are receiving multiple BGP routes from an upstream neighbor and only want to advertise a single summarized prefix to your internal OSPF neighbors. This route should only be advertised when you are receiving these BGP routes from this neighbor.
In this scenario, which type of route should you create?
정답：D
설명：
Both aggregate and generated routes would work, but the best choice is generated routes.
One key difference:
With aggregated routes any prefix in the routing table counts as a contributing route.
With generated routes only prefix with a valid next-hop qualifies.
질문 # 93
Which statement describes the additional overhead added when a packet is encapsulated in a GRE tunnel?
정답：C
설명：
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. Reference topics: Junos Enterprise Routing - Tunneling, GRE Header Overhead and MTU Planning.
