NEW QUESTION # 70
You are deploying IP phones in your enterprise network that must receive their power through their Ethernet connection. You are using your EX Series switch's PoE ports that support IEEE
802.3af. In this scenario, what is the maximum amount of power allocated to each interface?
Answer: C
Explanation:
PoE was first defined in the IEEE 802.3af standard, which supplied up to 15.4 W of power to a connected powered device. Subsequent versions increased the amount of power that can be supplied to a powered device.
NEW QUESTION # 71
Exhibit:
You are running OSPF as your IGP. The interfaces connecting two routers are in the ExStart state. You notice that something is incorrect with the configuration. Referring to the exhibit, which statement is correct?
Answer: D
NEW QUESTION # 72
Your OSPF network consists of a mix of 1GbE and 10GbE interfaces. By default, all interfaces have the same cost in your OSPF network. You are asked to ensure that the 10GbE interfaces are more preferred when available In this scenario, which two statements would accomplish this behavior? (Choose two.)
Answer: A,B
Explanation:
OSPF determines the best path to a destination by calculating the metric (cost) of each link. By default, Junos OS uses a reference bandwidth of 100 Mbps to calculate this cost using the formula:
When the reference bandwidth is left at the default 100 Mbps, any interface with a speed of 100 Mbps or higher (including 1 GbE and 10 GbE) is assigned a cost of 1 because the minimum OSPF cost is 1. This results in equal-cost paths, preventing the router from preferring the faster 10 GbE link.
To ensure 10 GbE interfaces are preferred, you must create a cost differential:
* Option A (Reference Bandwidth): By increasing the reference bandwidth to 10G (or higher), the calculation changes. For a 10 GbE link, the cost becomes $10,000 / 10,000 = 1$. For a 1 GbE link, the cost becomes $10,000 / 1,000 = 10$. Since OSPF prefers the path with the lowest cumulative cost, the
10 GbE link is now preferred.
* Option D (Manual Metric): You can manually override the automatic cost calculation by assigning a higher metric specifically to the 1 GbE interfaces. If a 1 GbE interface is manually set to a cost of 50 and the 10 GbE interface remains at 1 (or is set to a lower value), the router will prioritize the 10 GbE path.
Option B is incorrect because a higher metric makes a path less preferred. Option C is incorrect because a
1G reference bandwidth would still result in both 1 GbE and 10 GbE interfaces having a cost of 1.
NEW QUESTION # 73
Exhibit.
Referring to the exhibit, you see that the 0.0.0.0/0 route is coming from AS 64512.
What is the command to achieve this task?
Answer: D
Explanation:
The exhibit shows a BGP routing process where an Import Policy is being applied to routes received in the RIB-IN. Specifically, Policy 1 states: "Reject 0.0.0.0/0 from AS 64512." In Junos OS, when a routing policy rejects a route, that route is not placed in the main routing table (inet.0) for active use. Instead, it becomes a hidden route. To verify that a specific peer is actually sending a route that is subsequently being rejected by your policy, you must use specific diagnostic commands:
* Understanding "Hidden" Routes: When a BGP route is received but fails to meet policy requirements (or has an unreachable next-hop), Junos keeps it in the BGP RIB-IN but marks it as
"hidden." It will not appear in a standard show route command.
* Command Logic (Option D): The command show route receive-protocol bgp <peer ip> hidden allows an administrator to view all routes received from a specific neighbor, including those that were rejected by import policies.
* show route receive-protocol bgp <peer ip>: Shows only the routes that passed the import policy and were accepted into the table. Since the 0.0.0.0/0 route from AS 64512 is explicitly rejected in the exhibit, it would not show up here.
* Adding the hidden keyword is the essential step to see the rejected default route and verify that AS 64512 is indeed sending it before the policy drops it.
* Other Options:
* Option A is incorrect because it only shows accepted routes.
* Option B and C are used to filter the existing active routing table based on gateway or next-hop attributes, but they cannot show routes that have been rejected and excluded from that table.
