NEW QUESTION # 28
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
lowest router ID
lowest peer address
lower origin code
shortest AS path - B. higher local preference
shortest AS path
lowest peer address
lowest router ID
lower origin code - C. higher local preference
shortest AS path
lower origin code
lowest router ID
lowest peer address - D. higher local preference
shortest AS path
lowest router ID
lowest peer address
lower origin code
Answer: C
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

NEW QUESTION # 36
You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.
Which statement is correct in this scenario?
- A. Timers dictate when link state changes are propagated.
- B. The forbidden mode does not register or declare VLANs.
- C. MVRP works with RSTP and VSTP.
- D. When enabled, MVRP affects all interfaces.
Answer: B
Explanation:
The forbidden mode does not register or declare VLANs. You can change the registration mode of a specific interface to forbidden. An interface in forbidden registration mode does not participate in MVRP even if MVRP is enabled on the switch.
https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/mvrp.html MVRP is disabled by default on the switches and, when enabled, affects only trunk interfaces. Once you enable MVRP, all VLAN interfaces on the switch belong to MVRP (the default normal registration mode) and those interfaces accept PDU messages and send their own PDU messages. forbidden-The interface does not register or declare VLANS (except statically configured VLANs).
NEW QUESTION # 37
