質問 # 63
Which type of BGP community is used to control route advertisement scope across AS boundaries?
正解：D
質問 # 64
Exhibit
You need to configure the non-RP routers in your network to dynamically learn the location of the RP using standard protocols only. You have already applied the configuration shown in the exhibit, but the routers have not learned the location of the RP.
Which additional step must you take to fulfill these requirements?
正解：B
解説：
The exhibit shows a multicast network running PIM Sparse Mode where R2 is configured as a local Rendezvous Point (RP). However, the non-RP routers (like R5) show no learned RP in their show pim rps output. To resolve this using standard protocols for dynamic RP discovery, you must implement a mechanism that automates the distribution of RP information across the PIM domain.
* Bootstrap Router (BSR) (Option B): BSR is the industry-standard (RFC 5059) mechanism for dynamically electing an RP and distributing that information throughout a PIM-SM domain.
* It uses two roles: Candidate-RPs (C-RPs), which announce their desire to be an RP, and Candidate-BSRs (C-BSRs), which collect these announcements and flood them to all other routers in the network via PIM bootstrap messages.
* BSR is a "standard protocol" as it is part of the PIMv2 specification. Once configured on R2 (as C-RP) and potentially R1 or R2 (as C-BSR), all other routers will dynamically learn that R2 is the RP for the specified group ranges.
* Auto-RP (Option D): While this also provides dynamic RP discovery, it is a proprietary Cisco protocol. Although Junos supports it for interoperability, the question specifically asks for "standard protocols only," making BSR the preferred choice.
* MSDP (Option A): Multicast Source Discovery Protocol (MSDP) is used to share information about active sources between different PIM domains or for Anycast-RP. It does not handle the initial discovery of an RP within a single domain for standard PIM-SM operations.
* Anycast RP (Option C): This is a technique used for RP redundancy and load balancing. While it can use BSR or MSDP for synchronization, it is a design architecture rather than a standalone "standard protocol" for the basic dynamic discovery of an RP in the manner requested here.
Configuration Example for BSR in Junos OS 24.4: To enable this, you would add the following to the RP (R2):
set protocols pim rp bootstrap-discovery
set protocols pim rp candidate-rp 10.222.1.2 group-ranges 224.0.0.0/4
set protocols pim rp candidate-bsr 10.222.1.2
質問 # 65
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?
正解：B
解説：
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.
質問 # 66
You connected a printer to a network that does not support RADIUS. The printer can communicate with the network; however, you notice that when it initially connects to the network, there is a delay before it is able to get an address using DHCP. In this scenario, what would you do to improve the network experience for the printer?
正解：B
解説：
Configuring the printer port as a spanning tree edge port allows the interface to transition immediately to the forwarding state instead of waiting through normal spanning tree convergence timers. This reduces the delay before the printer can obtain a DHCP address and begin network communication.
質問 # 67
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.)
正解：B、D
解説：
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.
