NEW QUESTION # 37
Which address range is used for source-specific multicast?
- A. 224.2.0.0/16
- B. 233.0.0.0/8
- C. 232.0.0.0/8
- D. 239.0.0.0/8
Answer: C
Explanation:
PIM SSM introduces new terms for many of the concepts in PIM sparse mode. PIM SSM can technically be used in the entire 224/4 multicast address range, although PIM SSM operation is guaranteed only in the 232/8 range (232.0.0/24 is reserved). The new SSM terms are appropriate for Internet video applications and are summarized in Table 1. https://www.juniper.net/documentation/us/en/software/junos/multicast/topics/concept/multicast-pim-ssm.html

NEW QUESTION # 39
BGP multipath or multihop are not configured in your network.
In this scenario, what is the correct sequence for BGP active route selection?
- A. higher local preference
shortest AS path
lower origin code
lowest router ID
lowest peer address - B. higher local preference
shortest AS path
lowest peer address
lowest router ID
lower origin code - C. higher local preference
shortest AS path
lowest router ID
lowest peer address
lower origin code - D. higher local preference
lowest router ID
lowest peer address
lower origin code
shortest AS path
Answer: A
Explanation:
BGP Path Selection process follows this order
1.Weight (Bigger is better)
2. Local preference (Bigger is better)
3. Self originated (Locally injected is better than iBGP/eBGP learned)
4. AS-Path (Smaller is better)
5. Origin
6. MED (Smaller is better)
7. External (Prefer eBGP over iBGP)
8. IGP cost (Smaller is better)
9. EBGP Peering (Older is better)
10. Router- ID
