Question 370

A Junos network engineer takes this step: Deploy a supported anycast rendezvous-point design across redundant RP nodes. Which outcome most directly follows?

  1. Source-active information can be shared between participating RP nodes.
  2. Receivers can use one RP identity while multiple physical routers offer resilient RP service.
  3. Multicast control or data exchange for the protected groups can be contained within the intended domain.
  4. Unauthorized groups can be excluded from crossing the controlled boundary.

Explanation

Correct Answer

B:

This is the direct result of the Anycast RP resiliency decision: Receivers can use one RP identity while multiple physical routers offer resilient RP service.

Incorrect Answers

A:

This outcome is associated with MSDP source coordination (Use an appropriate Multicast Source Discovery Protocol peering design where supported.), not the specified action.

C:

This outcome is associated with Multicast group scoping (Apply a carefully scoped multicast policy or boundary to the prohibited group range.), not the specified action.

D:

This outcome is associated with Multicast import policy (Configure and apply supported multicast scoping or group filters for the allowed ranges.), not the specified action.

Question 371

An ASM service needs resilient RP access from different sites while clients use a single logical RP address. A colleague instead suggests: Use an appropriate Multicast Source Discovery Protocol peering design where supported. Which corrective approach most directly addresses the original issue?

  1. Apply a carefully scoped multicast policy or boundary to the prohibited group range.
  2. Configure and apply supported multicast scoping or group filters for the allowed ranges.
  3. Deploy a supported anycast rendezvous-point design across redundant RP nodes.
  4. Use an appropriate Multicast Source Discovery Protocol peering design where supported.

Explanation

Correct Answer

C:

This corrective choice addresses Anycast RP resiliency. Receivers can use one RP identity while multiple physical routers offer resilient RP service.

Incorrect Answers

A:

That alternative applies to Multicast group scoping instead. Multicast control or data exchange for the protected groups can be contained within the intended domain.

B:

That alternative applies to Multicast import policy instead. Unauthorized groups can be excluded from crossing the controlled boundary.

D:

That alternative applies to MSDP source coordination instead. Source-active information can be shared between participating RP nodes.

Question 372

An enterprise network designer recommends: Deploy a supported anycast rendezvous-point design across redundant RP nodes. Which situation most clearly calls for this action?

  1. A company must keep a specific internal multicast channel from crossing the enterprise perimeter.
  2. A Junos multicast border router must permit only explicitly approved multicast groups for forwarding across a policy boundary.
  3. Two independent anycast RPs must learn sources registered at the other RP in an ASM network.
  4. An ASM service needs resilient RP access from different sites while clients use a single logical RP address.

Explanation

Correct Answer

D:

This case requires the Anycast RP resiliency action. Receivers can use one RP identity while multiple physical routers offer resilient RP service.

Incorrect Answers

A:

This other case would be better matched to Apply a carefully scoped multicast policy or boundary to the prohibited group range. Multicast control or data exchange for the protected groups can be contained within the intended domain.

B:

This other case would be better matched to Configure and apply supported multicast scoping or group filters for the allowed ranges. Unauthorized groups can be excluded from crossing the controlled boundary.

C:

This other case would be better matched to Use an appropriate Multicast Source Discovery Protocol peering design where supported. Source-active information can be shared between participating RP nodes.

Question 373

Two independent anycast RPs must learn sources registered at the other RP in an ASM network. Which Junos networking action or protocol decision best addresses this requirement?

  1. Configure and apply supported multicast scoping or group filters for the allowed ranges.
  2. Apply a carefully scoped multicast policy or boundary to the prohibited group range.
  3. Deploy a supported anycast rendezvous-point design across redundant RP nodes.
  4. Use an appropriate Multicast Source Discovery Protocol peering design where supported.

Explanation

Correct Answer

D:

This action addresses MSDP source coordination. Source-active information can be shared between participating RP nodes.

Incorrect Answers

A:

That action targets Multicast import policy: Unauthorized groups can be excluded from crossing the controlled boundary. It does not directly resolve the stated MSDP source coordination requirement.

B:

That action targets Multicast group scoping: Multicast control or data exchange for the protected groups can be contained within the intended domain. It does not directly resolve the stated MSDP source coordination requirement.

C:

That action targets Anycast RP resiliency: Receivers can use one RP identity while multiple physical routers offer resilient RP service. It does not directly resolve the stated MSDP source coordination requirement.
