질문 # 205
Click the Exhibit button. You want the RSTP primary root path from switch C to traverse switch B.
Referring to the exhibit, which solution will accomplish this task?
정답：C
설명：
Switch A is already fixed as the root bridge in this topology (priority 0), so the outcome being engineered here is not about root bridge election at all, but about which of Switch C's two available paths toward that already-established root -- the direct C-to-A link, or the indirect C-to- B-to-A path -- RSTP selects as the lower-cost, primary path. RSTP's path-cost calculation for any non-root switch sums the port costs of every link along a candidate path to the root and always selects whichever candidate path has the lowest total accumulated cost as that switch's active root path, placing the corresponding local port into the forwarding root port role while any higher- cost alternative path is placed into a non-forwarding (alternate) role. To force Switch C to prefer routing through Switch B rather than connecting to Switch A directly, the administrator must make the direct C-to-A link's cost higher than the combined cost of the C-to-B link plus the B-to-A link added together, so that the indirect, two-hop path through Switch B mathematically totals to a lower cumulative cost than the single direct hop, causing RSTP's cost comparison to favor the indirect path as primary. Setting Switch B's priority (to either 1 or 0) is irrelevant here, since Switch B is not a root bridge candidate in this scenario and priority manipulation would only affect a root bridge election, not path cost preference between a fixed root and a downstream switch.
Lowering the direct link's cost, the inverse of the correct answer, would instead reinforce the direct path rather than override it.
질문 # 206
You are a network operator who wants to add a second ISP connection and remove the default route to the existing ISP You decide to deploy the BGP protocol in the network. What two statements are correct in this scenario? (Choose two.)
정답：A,B
설명：
The rules are as simple as follows:
1. IBGP peers advertise routes received from EBGP peers to other IBGP peers.
2. EBGP peers advertise routes learned from IBGP or EBGP peers to other EBGP peers.

질문 # 207
Click the Exhibit button. You are asked to ensure that there will not be any unwanted STP topology changes affecting your root bridge placement because a rogue switch was introduced into the network at the access layer. Referring to the exhibit, which interfaces will need to have root protection applied to accomplish this task?
정답：D
설명：
Root protection (root guard) must always be applied on the ports of the switches you trust to remain root-bridge-eligible, specifically on the interfaces facing away from the legitimate root and toward parts of the network where an untrusted or rogue device could plausibly appear and begin transmitting superior BPDUs. In this topology, Switch-1 is the intended, permanent root bridge (lowest priority, 4k), and Switch-2 is its aggregation-layer peer; both sit above the access layer, where Switch-3 and Switch-4 connect downstream toward end-user-facing infrastructure and where an accidental or malicious rogue switch is realistically most likely to be introduced. The ge-
0/0/6 and ge- 0/0/8 interfaces on Switch-1 and Switch-2 are precisely the downlink ports facing that access layer, meaning they are the exact points at which a rogue switch's superior BPDU (one advertising a lower priority than the legitimate root) would first be received if such a device appeared beneath Switch-3 or Switch-4. Applying root protection on those specific interfaces causes Junos to immediately block (move to a root-inconsistent, discarding state) any port that receives a superior BPDU, preventing the rogue device from ever being accepted as root, while normal, non-superior BPDUs continue to be processed without disruption. Applying root guard on Switch-1 and Switch-2's peer link (ge- 0/0/12/13) would be inappropriate, since that link legitimately connects two trusted, root-eligible switches.
질문 # 208
You are asked to explore deploying IS-IS in your network. What are two considerations in this scenario? (Choose two.)
정답：A,C
질문 # 209
You are required to ensure that Switch 1 will always be designated as the root bridge when participating in your switched network. What do you need to do to satisfy this requirement?
정답：D
설명：
Because root bridge election is decided primarily by comparing bridge priority values -- with the switch advertising the numerically lowest priority always winning, and MAC address serving only as a fallback tiebreaker when priorities are tied -- the only deterministic, reliable way to guarantee that a specific switch is elected root regardless of any other switch's hardware characteristics is to explicitly configure that switch with a lower bridge priority than every other participating switch in the topology. Relying on MAC address alone, as the first distractor suggests, is fundamentally unreliable: MAC addresses are burned in at the factory, cannot be predicted or controlled by the administrator, and any future hardware replacement or newly introduced switch with a numerically lower MAC address could unexpectedly seize the root role since MAC comparison only comes into play at equal priority in the first place, meaning a 'highest MAC' strategy does not even align with how the tiebreak actually favors the lowest value. Port priority and port cost are entirely separate STP parameters that influence which port on a non-root switch is selected as its root port, or which port is selected as designated versus blocking on a given segment; neither parameter has any bearing whatsoever on which switch is elected root bridge for the whole topology, since that decision is made purely from the Bridge ID comparison, independent of any per-port settings. Explicitly and deliberately lowering Switch 1's configured bridge priority is the only correct, industry-standard method.
