質問 # 60
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：D

解説：
The exhibit shows a multicast network runningPIM Sparse Modewhere 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 usingstandard protocolsfor 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 aproprietaryCisco 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 betweendifferentPIM 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 # 61
What is the function of a private VLAN?

正解：B


質問 # 62
Exhibit

You configured MVRP in your Layer 2 network using the configuration shown in the exhibit. You verified that the appropnate VLANs are configured and applied on the two access switches. You are using RSTP as your loop prevention mechanism. Unfortunately, the users are not able to communicate with their corresponding server attached to the Access-2 switch.
In this scenario, what should you do to solve this problem?

正解：B

解説：
The exhibit shows a network topology where Multiple VLAN Registration Protocol (MVRP) is used to dynamically manage VLANs across switches Core-1, Access-1, and Access-2.
* Identifying the Missing Configuration: According to the diagram, the trunk link between Core-1 and Access-2 uses interface ge-0/0/16.0 on the Core-1 side.
* Output Analysis: However, the show protocols mvrp output for Core-1 only lists interfaces ge-0/0/14.
0 and ge-0/0/15.0.
* MVRP Requirements: For MVRP to successfully propagate VLAN information between Access-2 and the rest of the network, the protocol must be enabled on every trunk interface in the path.
* Solution: Because ge-0/0/16.0 is missing from the Core-1 MVRP configuration, VLAN registration messages from Access-2 are not being processed by Core-1. Configuring this interface under MVRP on Core-1 will solve the communication problem.


質問 # 63
Exhibit

You are receiving the same BGP Internet routes on R1 from both upstream ISPs. You are asked to load- balance traffic destined to the Internet across both ISPs.
Referring to the exhibit, which BGP solution should you use?

正解：B

解説：
In standard BGP operations, a router typically selects only one " best path " for a given destination prefix and installs that single path into the forwarding table. To utilize multiple paths for traffic forwarding (load- balancing), specific multipath features must be enabled.
BGP Multipath: This feature allows a router to install multiple equal-cost paths into the routing and forwarding tables. However, by default, BGP multipath requires that all candidate paths have the same neighboring Autonomous System (AS).
Multipath Multiple-AS (Option B): In the exhibit, R1 is receiving routes from ISP A (AS 65501) and ISP B (AS 65502). Since these are two different neighboring ASs, the standard multipath feature is not sufficient.
You must use the multipath multiple-as statement under the BGP group or neighbor hierarchy. This tells Junos to consider paths as equal even if they originate from different neighboring ASs, provided all other BGP path selection attributes (Local Preference, AS Path length, Origin, MED, etc.) are identical.
Why other options are incorrect: * Option A (multihop) is used for peering with routers that are not directly connected.
Option C (prefix limit) is a security and stability feature to limit the number of prefixes received from a neighbor.
Option D (damping) is used to penalize unstable, " flapping " routes to prevent constant routing table churn.
Configuration Example for Junos OS 24.4: To implement this on R1, you would use the following configuration:
set protocols bgp group < group-name > multipath multiple-as


質問 # 64
You must provide network connectivity to hosts that fail authentication.
In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

正解：A
