質問 # 140
Which two multicast IP addresses are used for link-state update packets? (Choose two.)
正解：B、C
質問 # 141
An EBGP session sources its TCP connection from which IP address?
正解：D
質問 # 142
You are deploying an EX Series switch with a Wi-Fi access point. The access point needs all untagged traffic to use a specific VLAN. In this scenario, which feature should you enable on the switch port?
正解：A
質問 # 143
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?
正解：B
解説：
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. Reference topics: Junos Enterprise Routing - BGP Fundamentals, BGP Finite State Machine and Session Verification.
質問 # 144
Which two characteristics describe the default behavior of aggregate routes? (Choose two.)
正解：C、D
解説：
The entire purpose of route aggregation is summarization - replacing a set of more-specific contributing routes with a single, broader prefix advertised outward - and this summarization inherently hides internal routing instability from external peers: if one of the underlying contributing /24 blocks within a summarized
/16 flaps up and down due to a local link issue, external peers who only see the stable, unchanging /16 aggregate are completely insulated from that churn, since the aggregate itself remains active and advertised as long as at least one contributing route is present, regardless of how much internal fluctuation occurs among the individual contributors. This stability-hiding characteristic is one of the primary operational benefits that motivates using aggregate routes in the first place, confirming that statement as correct. Regarding next-hop behavior, official Juniper documentation is explicit and unambiguous: when an aggregate route is installed in the routing table, Junos assigns it a reject next hop by default, meaning traffic matching only the aggregate (and no more-specific contributor) is dropped and an ICMP unreachable message is returned to the source; a discard next hop is available only as an optional, explicitly configured alternative when silent dropping without ICMP notification is preferred, but it is not the default. Aggregate routes categorically do not advertise their individual contributing routes; suppressing those specific, more-granular prefixes from onward advertisement in favor of the single summary is the aggregate's defining function, directly contradicting the first statement. Reference topics: Junos Enterprise Routing - Protocol Independent Routing, Default Reject Next Hop and Route Summarization Benefits.
