NEW QUESTION # 48
Which two statements are true about VRRP? (Choose two.)
- A. Interfaces within the same VRRP group must be on the same subnet for each member.
- B. VRRP requires redundant REs on each member.
- C. VRRP does not require redundant REs on each member.

NEW QUESTION # 49
Exhibit
Referring to the exhibit, which statement is true about VRRP?
- A. The routers should use different virtual IP addresses for VRRP to function correctly.
- B. VRRP communication between the two devices is not functioning correctly.
- C. Both routers are in the same state because they have the same VRRP priority.
- D. VRRP Is functioning normally in active/active mode.
Answer: D
Explanation:
The exhibit shows theshow vrrp summaryoutput from two routers, with both routers listing the state of their VRRP group asmaster. VRRP allows for multiple routers to share a virtual IP address and a virtual MAC address, but usually, only one router is the master at any given time while others are in backup state. However, in some configurations, VRRP can operate in an active/active mode where multiple routers handle traffic simultaneously for load sharing. Since both routers show the state asmasterand there is no evidence of misconfiguration in the virtual IP addresses or priority, it indicates that VRRP is likely functioning in an active/active setup.

NEW QUESTION # 51
You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS routes are used to traverse your network. Your solution should not affect IGP routes in your route tables.
In this scenario, which traffic engineering setting will accomplish this behavior?
- A. mpls-forwarding
- B. bgp
- C. bgp-igp
- D. bgp-igp-both-ribs
Answer: B
Explanation:
bgp-On BGP destinations only. Ingress routes are installed in the inet.3 routing table.
bgp-igp-On both BGP and IGP destinations. Ingress routes are installed in the inet.0 routing table. If IGP shortcuts are enabled, the shortcut routes are automatically installed in the inet.0 routing table.
bgp-igp-both-ribs-On both BGP and IGP destinations. Ingress routes are installed in the inet.0 and inet.3 routing tables. This option is used to support VPNs.
mpls-forwarding-On both BGP and IGP destinations. Use ingress routes for forwarding only, not for routing.
NEW QUESTION # 52

NEW QUESTION # 57
Exhibit
Referring to the exhibit, which two additional steps should you lake to fully configure NSR? (Choose two.)
- A. You must configure GRES.
- B. You should configure the max period for NSR precision timers.
- C. You should configure commit synchronization.
- D. You must configure graceful restart.
Answer: A,C
Explanation:
https://www.juniper.net/documentation/us/en/software/junos/high-availability/topics/task/nsr-configuring.html Nonstop routing (NSR) requires both Graceful Routing Engine Switchover (GRES) and commit synchronization to be configured to maintain routing protocol and forwarding state during a Routing Engine switchover. NSR allows the secondary Routing Engine to take over the control plane without the protocols needing to restart, and GRES ensuresthat the forwarding plane continues operating with the current forwarding table. Commit synchronization ensures that configuration changes are synchronized between the primary and backup Routing Engines.

NEW QUESTION # 58
Exhibit
Referring to the exhibit, which two statements are correct? (Choose two.)
- A. Prefixes in Level 1 will not be redistributed to Level 2.
- B. Prefixes in Level 2 will be not redistributed to Level 1.
- C. Prefixes in Level 2 will be redistributed to Level 1.
- D. Prefixes in Level 1 will be redistributed to Level 2.
Answer: B,D
Explanation:
By default, IS-IS protocol leaks routing information from a Level 1 area to a Level 2 area. However, to leak routing information from a Level 2 area to a Level 1 area, an export policy must be explicitly configured.
NEW QUESTION # 59
Which BGP attribute Is used to detect touting loops?
- A. next hop
- B. MED
- C. AS path
- D. local preference
Answer: C
Explanation:
The AS path is a BGP attribute that lists the autonomous systems (AS) that routing information has passed through to get to a destination. It is used to detect and prevent routing loops by checking if the router's own AS number is in the path.
