質問 1：
Which protocol replicates forwarding information between MC-LAG peers?
A. VRRP
B. LLDP
C. VCCP
D. ICCP
正解：D

質問 2：
You want to configure redundant Layer 3 gateways
In this scenario, which two juniper best practices would accomplish this task? (Choose two.)
A. Configuring both IRB interfaces manually with the same address
B. Allowing Junos to dynamically create the virtual MAC address of the IRB interface
C. Configuring both IRB interfaces manually with the same IP address
D. Allowing Junos to dynamically create the virtual IP address of the IRB interface
正解：C,D

質問 3：
You are implementing perimeter security for your data center. You need to inspect all traffic Layer 7 and ensure the failure of a port or device will not result in an interruption to traffic flows.
In this scenario, which design would satisfy these requirements?
A. MX with MC LAG
B. QFX Virtual Chassis
C. SRX using LAG
D. SRX Chassis cluster
正解：D

質問 4：
You have a site with thousands of MAC addresses multihomed to two leaf nodes in an EVPN VXLAN.
In this scenario, which EVPN feature provides fast network convergence in the event of a leaf node link failure?
A. BGP Additional Paths
B. Fast rerouter
C. Ethernet Autodiscovery
D. Bidirectional Forwarding detection
正解：C

質問 5：
Your colleague has begun working on the base configuration for an active-active multihomed EVPN connection shown in the exhibit.

Which two actions will ensure a successful implementation? (Choose two.)
A. Change the ESI mode on PE1 to signal-active
B. Change the ESI value on the PE1 device to 00.22.44.88.00.22.44.66.88
C. Change the ESI mode on PE2 to all-active
D. Change the ESI value on the PE2 device to 00.00.00.00.00.00.00.00.00.00
正解：B,C

質問 6：
You are asked to manage the oversubscription ratio of your spine and leaf IP fabric. You determine that you are at a 3:1 ratio of downstream to upstream traffic and must achieve a 1.1ratio.
In this scenario, which two actions would you take to achieve this goal? (Choose two.)
A. Increase the number of spine nodes in your design.
B. Reduce the number of server facing that each leaf node uses to carry traffic.
C. Increase the number of server facing ports that each leaf node uses to carry traffic.
D. Reduce the number of leaf nodes on your design.
正解：A,B

質問 7：
You are configuring an IP Fabric in your data center and you are trying to load-balance traffic across multiple equal-cost BGP routes. You have enabled multipath, but the traffic is not being load-balanced.

Referring to the exhibit, what will solve this problem?
A. You should apply the load-balance policy as an export policy to the forwarding table
B. You should apply load-balance policy as an import policy to the forwarding table
C. You should apply the load-balance policy as an export policy to the BGP neighbor
D. You should apply the load-balance policy as an export policy for the BGP neighbor
正解：A
