NEW QUESTION # 88
Exhibit

R4 is directly connected to both RPs (R2 and R3) R4 is currently sending all ,o,ns upstream to R3 but you want all joins to go to R2 instead Referring to the exhibit, which configuration change will solve this issue?

  • A. Change the local address on R2 to be higher than R3.
  • B. Change the default route in inet.2 on R4 from R3 as the next hop to R2
  • C. Change the group-range to be more specific on R2 than R3.
  • D. Change the bootstrap priority on R2 to be higher than R3

Answer: C

Explanation:
The issue arises because R3's group-range (224.1.1.0/28) is more specific than R2's group-range (224.1.1.0/24). In PIM bootstrap (BSR), the RP with the longest prefix (most specific group-range) is preferred, regardless of priority. Even though R3 has a higher bootstrap priority (210 vs. R2's 200), its more specific /28 group-range takes precedence for groups within 224.1.1.0/28.
Why Option D is Correct:
To force R4 to use R2 for all joins, R2's group-range must be more specific than R3's. For example:
If R2's group-range is changed to 224.1.1.0/28 (same as R3) but with a higher priority, R2 would win (priority is compared only when group-ranges are equal).
If R2's group-range is changed to 224.1.1.0/29 (more specific than /28), it will override R3's /28 for groups in the /29 range.
The key is prefix specificity, which overrides priority in BSR elections.
Why Other Options Are Incorrect:
A . Change bootstrap priority on R2 to be higher than R3:
Priority is evaluated only when group-ranges are identical. Since R3's group-range (/28) is more specific than R2's (/24), R3 will still win for groups in 224.1.1.0/28, even if R2's priority is higher.
B . Change the default route in inet.2 on R4:
RPF routes (inet.2) determine how traffic reaches the RP, but they do not influence RP election logic (BSR priority/group-range).
C . Change R2's local address to be higher than R3's:
The RP address is a tiebreaker only if priorities and group-ranges are equal. Since R3's group-range is more specific, this change has no impact.
Key Takeaways:
BSR RP Election Order:
Longest group prefix (most specific).
Highest priority (if prefixes are equal).
Highest RP address (if prefixes and priorities are equal).
To override R3, R2 must advertise a more specific group-range (e.g., /28 or smaller) to ensure it is selected for the desired multicast groups.

NEW QUESTION # 89
Exhibit

Based on the configuration contents shown in the exhibit, which statement is true?

  • A. Joins for group 224.7.7.7 are rejected if the source address is 192.168.100.10
  • B. Joins for any group are accepted if the group count value is less than 25.
  • C. Joins for group 224.7.7.7 are accepted if the group count is less than 25
  • D. Joins for group 224.7.7.7 are always rejected, regardless of the group count.

Answer: C

Explanation:
BGP policy framework is a set of tools that allows you to control the flow of routing information and apply routing policies based on various criteria. BGP policy framework consists of several components, such as route maps, prefix lists, community lists, AS path lists, and route filters. Route maps are used to define routing policies by matching certain conditions and applying certain actions. Prefix lists are used to filter routes based on their prefixes. Community lists are used to filter routes based on their community attributes. AS path lists are used to filter routes based on their AS path attributes. Route filters are used to filter routes based on their prefix length or range3. In this question, we have a route map named ISP-A that has two clauses: clause 10 and clause 20. Clause 10 matches any route with a prefix length between 8 and 24 bits and sets the local preference to 200. Clause 20 matches any route with a prefix of 224.7.7.7/32 and rejects it. The route map is applied inbound on the BGP neighborship with ISP-A. Based on this configuration, the correct statement is that joins for group 224.7.7.7 are always rejected, regardless of the group count. This is because clause 20 explicitly denies any route with a prefix of 224.7.7.7/32, which corresponds to the multicast group 224.7.7.7.


NEW QUESTION # 90
Exhibit

Which two statements about the configuration shown in the exhibit are correct? (Choose two.)

  • A. This VPN connects customer sites that use different AS numbers.
  • B. This VPN connects customer sites that use the same AS number
  • C. A Layer 2 VPN is configured.
  • D. A Layer 3 VPN is configured.

Answer: A,D

Explanation:
Explanation
The configuration shown in the exhibit is for a Layer 3 VPN that connects customer sites that use different AS numbers. A Layer 3 VPN is a type of VPN that uses MPLS labels to forward packets across a provider network and BGP to exchange routing information between PE routers and CE routers. A Layer 3 VPN allows customers to use different routing protocols and AS numbers at their sites, as long as they can peer with BGP at the PE-CE interface. In this example, CE-1 is using AS 65530 and CE-2 is using AS 65531, but they can still communicate through the VPN because they have BGP sessions with PE-1 and PE-2, respectively.


NEW QUESTION # 91
You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. Your PE-2 device connects to two sites within the s VPN In this scenario, which statement is correct?

  • A. By default on PE-2, the remote site IDs are automatically assigned based on the order that you add the interfaces to the site configuration.
  • B. By default on PE-2, the site's local ID is automatically assigned a value of 0 and must be configured to match the total number of attached sites.
  • C. You must use separate physical interfaces to connect PE-2 to each site.
  • D. You must create a unique Layer 2 VPN routing instance for each site on the PE-2 device.

Answer: A

Explanation:
Explanation
BGP Layer 2 VPNs use BGP to distribute endpoint provisioning information and set up pseudowires between PE devices. BGP uses the Layer 2 VPN (L2VPN) Routing Information Base (RIB) to store endpoint provisioning information, which is updated each time any Layer 2 virtual forwarding instance (VFI) is configured. The prefix and path information is stored in the L2VPN database, which allows BGP to make decisions about the best path.
In BGP Layer 2 VPNs, each site has a unique site ID that identifies it within a VFI. The site ID can be manually configured or automatically assigned by the PE device. By default, the site ID is automatically assigned based on the order that you add the interfaces to the site configuration. The first interface added to a site configuration has a site ID of 1, the second interface added has a site ID of 2, and so on.
Option D is correct because by default on PE-2, the remote site IDs are automatically assigned based on the order that you add the interfaces to the site configuration. Option A is not correct because by default on PE-2, the site's local ID is automatically assigned a value of 0 and does not need to be configured to match the total number of attached sites. Option B is not correct because you do not need to create a unique Layer 2 VPN routing instance for each site on the PE-2 device. You can create one routing instance for all sites within a VFI. Option C is not correct because you do not need to use separate physical interfaces to connect PE-2 to each site. You can use subinterfaces or service instances on a single physical interface.


NEW QUESTION # 92

Click the Exhibit button.
You are troubleshooting an issue for a customer site that uses 10.10.0.0/24 in AS 65224, but you see another AS in the AS path.

  • A. AS 65000 is pre-pending AS 65137 to route advertisements.
  • B. AS 65137 is advertising the 10.10.0.0/24 prefix.
  • C. The local AS is receiving two equal cost routes to 10.10.0.0/24.
  • D. The local AS is in the process of withdrawing the route from AS 65137.

Answer: B
