질문 # 37
Exhibit
You are running a service provider network and must transport a customer's IPv6 traffic across your IPv4-based MPLS network using BGP You have already configured mpis ipv6-tunneling on your PE routers.
Which two statements are correct about the BGP configuration in this scenario? (Choose two.)
정답：A,B
설명：
To transport IPv6 traffic over an IPv4-based MPLS network using BGP, you need to configure two address families: family inet6 labeled-unicast and family inet6 unicast. The former is used to exchange IPv6 routes with MPLS labels between PE routers, and the latter is used to exchange IPv6 routes without labels between PE and CE routers. The mpis ipv6-tunneling command enables the PE routers to encapsulate the IPv6 packets with an MPLS label stack and an IPv4 header before sending them over the MPLS network.

Exhibit
You must ensure that the VPN backbone is preferred over the back door intra-area link as long as the VPN is available. Referring to the exhibit, which action will accomplish this task?
정답：D
설명：
A sham link is a logical link between two PE routers that belong to the same OSPF area but are connected through an L3VPN. A sham link makes the PE routers appear as if they are directly connected, and prevents OSPF from preferring an intra-area back door link over the VPN backbone. To create a sham link, you need to configure the local and remote addresses of the PE routers under the [edit protocols ospf area area-id] hierarchy level1.

질문 # 39
You are configuring schedulers to define the class-of-service properties of output queues. You want to control packet drops during periods of congestion.
In this scenario, which CoS configuration parameter would be used to accomplish this task?
정답：D
설명：
When configuring Class of Service (CoS) properties for output queues, we need to manage packet drops during periods of congestion. Juniper's CoS framework provides several tools to manage congestion, including drop profiles, buffer sizes, and scheduling mechanisms. Let's break down each option and identify the correct one.
Evaluating the Answer Choices
# D. drop profile (Correct Answer)
* Why?
* A drop profile defines when packets should be dropped based on the queue fill level.
* Random Early Detection (RED) or Tail Drop can be used to manage congestion by discarding lower-priority packets first.
* Drop profiles are configured under the scheduler to determine how aggressive packet dropping should be during congestion.
* Example Juniper Configuration:
schedulers {
best-effort {
drop-profile low-drop;
}
}
drop-profiles {
low-drop {
fill-level 80 drop-probability 50;
}
}
* fill-level 80 # When the queue reaches 80% full, packet drops begin.
* drop-probability 50 # There is a 50% chance of dropping packets once the threshold is reached.
# Official Juniper Documentation Reference:
# Junos Class of Service Configuration Guide
"A drop profile determines how packets are discarded based on the queue fill level, allowing control over congestion behavior." Why the Other Options Are Incorrect?
# A. buffer size (Incorrect)
* Why?
* The buffer size determines how many packets the queue can store before congestion occurs.
* A larger buffer can delay drops, but it does not actively control dropping behavior.
* It affects latency rather than controlling packet drops.
# B. priority (Incorrect)
* Why?
* Priority controls which queue gets serviced first, not how drops are handled.
* Higher priority queues are serviced before lower-priority queues, but this does not prevent congestion-related drops.
# C. shaping rate (Incorrect)
* Why?
* Shaping limits the maximum transmission rate of the queue.
* While shaping helps reduce congestion, it does not control which packets get dropped during congestion.
* Shaping is useful for traffic smoothing, but it does not actively drop packets based on queue fill levels.
# D. drop profile
* Controls packet drops based on queue congestion.
* Defines RED (Random Early Detection) or Tail Drop mechanisms.
* Directly influences drop probability as the queue fills up.
# Official Juniper Reference:
"Drop profiles are used to manage congestion by determining when and how aggressively packets are dropped based on queue fill level."
질문 # 40
Exhibit
Referring to the exhibit, PIM-SM is configured on all routers, and Anycast-RP with Anycast-PIM is used for the discovery mechanism on RP1 and RP2. The interface metric values are shown for the OSPF area.
In this scenario, which two statements are correct about which RP is used? (Choose two.)
정답：B,D
설명：
A sham link is a logical link between two PE routers that belong to the same OSPF area but are connected through an L3VPN. A sham link makes the PE routers appear as if they are directly connected, and prevents OSPF from preferring an intra-area back door link over the VPN backbone. A sham link creates an OSPF multihop neighborship between the PE routers using TCP port 646. The PEs exchange Type 1 OSPF LSAs instead of Type 3 OSPF LSAs for the L3VPN routes, which allows OSPF to use the correct metric for route selection1.
