質問 1：
A customer's traffic is traversing your network, which consists of Junos devices. You must configure class of service for the traffic to meet a service-level agreement.
In this scenario, which two statements are true? (Choose two.)
A. A packet's loss priority can be set using classifiers or rewrite markers.
B. By default, a packet's loss priority can be either low, medium-low, medium-high, or high.
C. A packet's loss priority can be set using classifiers or policers.
D. By default, a packet's loss priority can be either low or high.

質問 2：
You have recently configured an aggregated Ethernet interface between two devices in your network. The member links do not all reside within the same PFE complex. You must ensure that the bandwidth and burst size defined in a policer applied to this aggregated Ethernet interface are properly enforced when the traffic falls out of profile.
Which configuration parameter should you use?
A. shared-bandwidth-policer
B. committed-information-rate
C. physical-interface-policer
D. committed-burst-size
正解：A
質問 3：
Refer to the exhibit.
A. Option C
B. Option A
C. Option D
D. Option B
正解：C
質問 4：
Which two statements describe the benefits of using point-to-multipoint LSPs in an environment with MVPNs? (Choose two.)
A. A service provider network does not need to run PIM to support multicast routing.
B. Multicast traffic can be protected, regardless of the signaling protocol used.
C. Performance levels within the LSPs can be guaranteed, regardless of the signaling protocol used.
D. Data replication can be done by downstream LSRs and not just by the ingress PE router.
正解：A,D
質問 5：
You want to ensure that your all-Junos MPLS core network does not decrease the TTL when using ping and traceroute from IP endpoints. Which two configuration parameters satisfy this requirement? (Choose two.)
A. no-propagate-ttl, configured on all routers in the path
B. no-decrement-ttl, configured on the ingress router only
C. no-propagate-ttl, configured on the ingress router only
D. no-decrement-ttl, configured on all routers in the path
正解：A,B
質問 6：
You are asked to implement an LDP-signaled VPLS network for a new customer. Which two statements are correct regarding this implementation? (Choose two.)
A. The same NLRI as Layer 2 VPNs is used.
B. The PE router advertises a label for each remote PE configured.
C. The PE routers distribute VPLS to label mapping using MP-IBGP.
D. A full mesh of LDP sessions between PEs must be configured.
正解：B,D
質問 7：
PE1 and PE2 provide a BGP-signaled VPLS service named VPN Blue. PE1 has site ID 2, label base 2500, and label offset 1. PE2 has site ID 4, label base 3000, and label offset 1.
Which label does PE2 expect to receive on VPLS VPN Blue traffic received from PE1 site ID 2?
A. 2505
B. 3001
C. 2503
D. 5499
正解：C
