NEW QUESTION # 198
Which statement describes how a generated route determines its next hop?
Answer: A
Explanation:
A generate route is a specialized type of Junos summary route that, unlike an aggregate route, is permitted to inherit and use an actual forwarding next hop rather than being restricted to reject or discard. When multiple contributing routes exist beneath the summarized prefix, Junos selects one of them as the primary contributor using a deterministic process: it first evaluates route preference (choosing the contributor with the lowest, most preferred value), then breaks any remaining tie by preferring the contributing route with the numerically lowest metric, and continues through further tie-breaking criteria if necessary until a single primary contributor is identified. The generate route then adopts the next hop of that specific primary contributor as its own forwarding next hop, meaning traffic matching the generate route but not matching any individual contributing route is forwarded toward whichever real next hop the primary (best) contributing route currently uses. This behavior is fundamentally different from an aggregate route, which never adopts a forwarding next hop at all and instead installs with a reject (or optionally discard) next hop by default, deliberately preventing traffic from being forwarded toward a next hop that might not actually lead to the intended more-specific destination. There is no mechanism by which the next hop is chosen arbitrarily from the 'first' or 'least- specific' contributor, and while a next hop can be manually overridden under the generate route's own configuration, that is not the default resolution behavior being described here.

NEW QUESTION # 199
After receiving a BGP route, which two conditions are verified by the receiving router to ensure that the received route is valid? (Choose two)
Answer: A,D
Explanation:
B is correct because the loops do not exist is one of the conditions that are verified by the receiving router to ensure that the received BGP route is valid. A loop in BGP means that a route has been advertised by the same AS more than once, which can cause routing instability and inefficiency. To prevent loops, BGP uses the AS-path attribute, which lists the AS numbers that a route has traversed from the origin to the destination. The receiving router checks the AS-path attribute of the received route and discards it if it finds its own AS number in the list. This way, BGP avoids accepting routes that contain loops.
C is correct because the next hop is reachable is one of the conditions that are verified by the receiving router to ensure that the received BGP route is valid. The next hop is the IP address of the next router that is used to forward packets to the destination network. The receiving router checks the next hop attribute of the received route and verifies that it has a valid route to reach it.
If the next hop is not reachable, the received route is not usable and is rejected by the receiving router. This way, BGP ensures that only feasible routes are accepted.
NEW QUESTION # 200
How does BGP prevent routing loops between internal peers?
Answer: C
Explanation:
BGP employs two distinct loop-prevention mechanisms depending on whether peers are external or internal to the same autonomous system. Between external peers (EBGP), loop prevention relies on the AS path attribute: every time a route crosses an AS boundary, the local AS number is prepended to the path, and a router rejects any incoming route whose AS path already contains its own AS number, since that would indicate the route has looped back around. Between internal peers (IBGP) within the same AS, however, the AS path attribute never changes, because IBGP does not add AS numbers as routes are readvertised internally
- meaning AS path alone cannot detect an internal loop. Instead, IBGP enforces a strict split-horizon-style rule: a router that learns a route via IBGP must never readvertise that route to another IBGP peer. This rule guarantees that every IBGP speaker within the AS must be directly peered with every other IBGP speaker (a logical full mesh) in order for all routers to receive all routes, since no IBGP router will relay IBGP-learned routes onward on another router's behalf. This full-mesh requirement is precisely why techniques such as route reflection and confederations were later developed - they preserve the same loop-prevention guarantee while relaxing the physical full-mesh peering burden. VRRP and BFD serve entirely unrelated purposes (gateway redundancy and fast failure detection, respectively) and play no role in BGP loop prevention.

NEW QUESTION # 201
You are deploying a Juniper Networks EX Series Switch to connect 24 end devices to VLAN 70, with an uplink interface to a distribution switch that carries VLANs 30, 50, and 70. You need to correctly configure the interface type for the end-device interfaces.
In this scenario, which statement is correct?
Answer: A
Explanation:
Each of the 24 end-device-facing interfaces in this scenario needs to carry traffic for exactly one VLAN, and the end devices themselves are ordinary hosts that neither expect nor generate 802.1Q-tagged frames. This is precisely the definition of an access port in Junos: family ethernet-switching interface-mode is set to access, and a single vlan members statement assigns the port to VLAN 70. Access mode ensures frames egressing toward the host are untagged and any frames received are implicitly treated as belonging to the configured VLAN, which is both simpler to manage and more efficient than trunking, since access ports do not carry the
802.1Q tag overhead nor process VLAN pruning logic relevant only to multi-VLAN links. Trunk mode, by contrast, is reserved for switch-to-switch or switch-to-router links that must simultaneously carry frames for multiple VLANs, such as the uplink toward the distribution switch that transports VLANs 30, 50, and 70 together - configuring the 24 host-facing ports as trunks (with or without a native VLAN) would be functionally incorrect and operationally wasteful, since end devices have no need to interpret VLAN tags.
There is also no such behavior in Junos where VLAN-ID numeric value dictates default port behavior, making the 'no configuration needed' option a distractor with no basis in EX Series switching architecture.

NEW QUESTION # 202
Your router receives two BGP routes for the same prefix. One route is learned from an IBGP neighbor, and the other route is learned from an EBGP neighbor. By default, which route will be selected as active in this scenario?
Answer: D
Explanation:
Once the two candidate routes have equal route preference and equal local preference (both defaulting to 100 unless modified by policy), the Junos BGP algorithm proceeds to its third decision step, which compares the length of each candidate's AS path attribute and selects whichever path carries the shortest AS path, since a shorter path is interpreted as traversing fewer autonomous system hops to reach the origin. This step occurs well before the algorithm ever reaches the specific EBGP-over-IBGP preference rule, which is only evaluated later, after local preference, AS path length, origin type, and MED have all already been compared and found equal between the candidates; because an IBGP-learned copy of a route typically retains the identical AS path that was originally received from the external AS (IBGP does not prepend the local AS number the way crossing an AS boundary does), it is entirely possible, and often the deciding scenario, for AS path length to differ between competing paths well before the algorithm would ever need to fall back on the IBGP- versus-EBGP tiebreak. Selecting a route purely because it was 'learned through IBGP' is not a rule that exists anywhere in the algorithm and would in fact typically be the opposite of Junos's later EBGP-preference tiebreak. Neither next- hop IP address value nor router ID value is compared with a 'highest wins' rule at any point in the standard path selection sequence -- where router ID is used at all, Junos prefers the lowest value, not the highest, making both of those distractors doubly incorrect.
