질문 # 110
You need to configure a LAG between your switches. In this scenario, which two statements are correct? (Choose two.)
정답：B,C
설명：
Up to 64 Ethernet interfaces can be grouped to form a LAG, and In a Junos Fusion, up to 1,000 LAGs are supported on QFX10002 switches acting as aggregation devices.
The LAG must be configured on both sides of the link.
The interfaces on either side of the link must be set to the same speed and be in full-duplex mode.
질문 # 111
What determines the preferred route to a destination in an IS-IS network?
정답：A
설명：
IS-IS is a link-state protocol that, like OSPF, runs Dijkstra's Shortest Path First algorithm independently on each router against its own copy of the synchronized link-state database to compute the best path toward every reachable destination. Each link within the topology carries an administrator-assigned or default metric, and as the SPF algorithm walks the topology graph from the local router outward, it sums the metrics of every link traversed along a candidate path to produce that path's total accumulated cost. Among all possible paths to a given destination prefix, IS-IS always selects and installs the path (or, in the case of equal-cost multipath, the set of paths) with the numerically lowest total accumulated metric, exactly mirroring the 'lowest cost wins' principle shared by essentially all link-state IGPs. A higher accumulated metric value is by definition a less preferred, more costly path, making that option the direct inverse of correct IS-IS behavior. Level 2 proximity to the destination has no independent bearing on path selection beyond however it happens to be reflected in the accumulated metric itself - IS-IS does not apply a separate rule preferring paths merely for passing near a Level 2 router. Likewise, LSP recency (sequence number or freshness) governs which version of a given LSP is trusted and flooded during database synchronization, ensuring the topology database itself is accurate and loop-free, but it plays no role in the SPF cost comparison once the database is synchronized and consistent.

질문 # 112
You are creating an aggregated Ethernet bundle using LACP on your Juniper Networks EX Series device. In this scenario, which statement is correct?
정답：A
설명：
IEEE 802.3ad LACP defines two distinct negotiation modes, active and passive, and the standard's fundamental requirement for successful negotiation is that at least one end of the point-to-point link must be configured in active mode; an actively configured device initiates LACPDU transmission on its own, while a passively configured device waits and only responds once it receives an LACPDU from its peer. If both ends of the bundle were left in passive mode simultaneously, neither side would ever initiate the exchange, and no negotiation -- and therefore no functioning aggregated bundle -- would ever occur; at least one active participant is therefore mandatory, though having both sides active (active-active) is also fully valid and is in fact the most common production deployment. Junos does not enable LACP automatically on aggregated Ethernet interfaces; unlike some competing platforms, LACP must be explicitly configured under the aggregated-ether-options lacp hierarchy, and specifying no LACP configuration at all results in a 'static' LAG that relies purely on physical link-state rather than any protocol negotiation -- there is no implicit default active mode. There is likewise no requirement to configure differing LACP system priority values between the two peer switches; system priority is used only to determine which side of the link controls port selection during negotiation and has no bearing on whether the bundle can form. Both sides being mandatorily active is a stricter requirement than the actual standard specifies.
질문 # 113
A number of reports from end users indicate that internal and external communications are intermittent and not reliable. You verified the status of the switch ports and have determined that they are up and operational. You also noticed a very high level of link bandwidth utilization on those same ports. The current topology of the affected environment is shown in the exhibit.
What would be the cause of the reported issues?
정답：C
질문 # 114
What are two characteristics of IS-IS? (Choose two.)
정답：A,B
설명：
IS-IS (Intermediate System to Intermediate System) was designed by ISO as a link-state Interior Gateway Protocol for routing within a single autonomous system, functioning on a hierarchical two-level model conceptually similar to OSPF's areas, which makes the first statement unambiguously correct. Within that hierarchy, Level 1 routers maintain detailed topology information only for their own local area and use a default route toward the nearest Level 2 or Level 1/Level 2 router to reach destinations outside the area; they explicitly do not carry inter-area topology information and therefore cannot route traffic between areas on their own. Routers that participate in both levels simultaneously - Level 1/Level 2 (L1/L2) routers - sit at the area boundary, maintaining a Level 1 database for their local area and a Level 2 database for the backbone, and it is specifically these dual-level routers that stitch inter-area traffic together, forwarding packets from the local area into the Level 2 backbone and vice versa, which confirms the second correct statement. Regarding route preference, Junos assigns distinct default preference (administrative distance) values of 15 for IS-IS Level 1 routes and 18 for IS-IS Level 2 routes - neither of which is 20 - so the preference-value statement is factually incorrect and included as a distractor testing precise knowledge of Junos default protocol preferences.
