질문 # 204
You are establishing a new BGP session to an EBGP peer using loopback addresses.
In addition to your general EBGP settings, which BGP feature must be enabled for this session to establish?
정답：B
설명：
By default, EBGP sessions are built with the expectation that peers are directly connected at Layer 3, and Junos enforces this by sending EBGP packets with a TTL of 1. When loopback addresses are used as the session endpoints instead of the directly connected physical interface addresses, the resulting IP packets must traverse at least one additional router hop between the two loopbacks, and a TTL of 1 will expire in transit before reaching the remote loopback, causing the TCP handshake - and therefore the BGP session - to fail even though a valid route to the peer's loopback exists. The multihop statement (configured as an EBGP multihop parameter with an accompanying TTL value, most commonly set to 2 for a single intermediate hop) instructs Junos to increase the TTL used for that peer's BGP packets so they survive the extra hop count between loopbacks. This is a mandatory addition any time an EBGP session is deliberately built against non- directly-connected addresses, whereas IBGP sessions, by contrast, do not have this default restriction because IBGP already assumes peers may be multiple hops apart within the same AS. Multipath affects load-balancing across equal-cost paths, damping suppresses flapping routes, and passive controls whether a router waits for the remote peer to initiate the TCP connection - none of these resolve the TTL expiration problem inherent to loopback-based EBGP peering.

질문 # 205
Referring to the exhibit, which statement is correct?
정답：D
설명：
The "Root ID" shows 4096.00:19:e2:55:36:1e. The first part of this ID, 4096, is the bridge priority of the root bridge.
The local bridge ID is shown as 32768.00:19:e2:55:1d:30, indicating that the local device has a default bridge priority of 32768, which is higher (and thus less preferred) than 4096.
Thus, the root bridge has a priority of 4096, and the local device is not the root bridge. The local device is participating in the RSTP topology and has identified another bridge as the root.
질문 # 206
Two Juniper Networks EX Series Switches are connected with four 1-GbE links configured as a single link aggregation group (LAG). One of the physical member links experiences a failure.
By default, what impact will this failure have on traffic forwarding between the switches?
정답：B
설명：
A link aggregation group bundles multiple physical Ethernet links into a single logical interface (an ae interface) specifically to provide both increased aggregate bandwidth and link-level redundancy. By default, the aeX interface remains operationally up as long as at least one member link within the bundle remains active and passing traffic; the LAG does not require every member link to be functional to continue operating.
When one of the four 1-GbE member links in this scenario fails, LACP (if in use) or the underlying link- status monitoring detects the failure, removes that specific link from the active forwarding set, and redistributes traffic hashing across the three remaining healthy member links automatically and without operator intervention. End devices and upper-layer protocols continue to see a single, continuously up ae interface throughout this process, experiencing only a proportional reduction in available aggregate bandwidth rather than any interruption in connectivity. This default behavior is precisely why LAG is a foundational building block for resilient EX Series switch interconnects in enterprise and data center designs, since it allows individual optic, cable, or transceiver failures to be absorbed transparently. None of the distractor behaviors - full administrative shutdown of the bundle, forwarding limited to broadcast traffic only, or a temporary disabling of all member links during renegotiation - reflect actual Junos LAG behavior, which is designed explicitly to avoid any such disruption. Reference topics: Junos Enterprise Switching - Layer 2 Switching, Link Aggregation Group Resiliency.
질문 # 207
Which two statements are correct about BGP local preference? (Choose two.)
정답：A,C
설명：
Local preference is a well-known, discretionary BGP path attribute carried exclusively in IBGP UPDATE messages, and Junos assigns every route a local preference value of 100 by default whenever a route is received without an explicit LOCAL_PREF value already attached, or when the attribute has not been otherwise modified through routing policy. This default of 100 becomes the implicit baseline against which any administrator-configured local preference adjustments are compared. Because higher local preference values are always preferred over lower ones during BGP best-path selection -- and this evaluation happens before AS path length, origin, or MED are ever considered -- network engineers commonly use local preference specifically to steer outbound traffic leaving the autonomous system toward a preferred exit peer or upstream provider, by assigning a higher local preference to routes learned from that preferred peer relative to routes learned from alternative peers, making the third statement correct as well. Local preference is explicitly excluded from advertisement to EBGP peers under the BGP specification; it is meaningful only within the boundaries of a single AS and is stripped before a route crosses an AS boundary outward, since a neighboring AS has no reason to trust or honor another organization's internal preference values. A local preference of 0 does not have any special 'drop' semantics in BGP -- it is simply the lowest possible numeric preference value and is treated like any other value during comparison, not as a discard instruction.
질문 # 208
In addition to the MAC addresses, what information is stored in the bridging table? (Choose two.)
