Answer: B

NEW QUESTION # 35
Which two statements are correct about switch adoption?(Choose two.)

• A. Greenfield switch adoption requires cloud-enabled switches with a claim or activation code.
• B. Switch adoption requires Mist AP.
• C. Switch adoption uses SSH over TCP port 443.
• D. Brownfield switch adoption requires manual adoption and is used for switches that do not have a claim or activation code.

Answer: A,D

Explanation:
In Juniper Mist,Greenfield adoptionapplies to new, cloud-ready switches (such as EX4100, EX4400, and QFX series) using aclaim or activation codeto securely connect to the Mist cloud.
Brownfield adoption, however, supports switches already deployed or not factory-fresh. These are manually onboarded by configuring outbound management connectivity and adopting them through the Mist portal.
This distinction enables both new and legacy EX/QFX environments to be cloud-managed under Wired Assurance.

• A. Throughput
• B. Capacity
• C. Switch Health
• D. Successful Connect

Answer: A

Explanation:
InJuniper Mist Wired Assurance, SLEs (Service Level Expectations) measure key performance indicators for wired network quality.Throughput SLEmonitorsdata transfer quality, includinglatency, jitter, and packet loss, which directly impact real-time applications such as voice or video.
"The Throughput SLE provides visibility into end-to-end network performance by tracking latency, jitter, and packet loss, helping identify congestion or quality issues across wired connections." Option A (Throughput):Correct- this SLE includes jitter measurement.
Option B (Successful Connect):Tracks client connection success rate, not jitter.
Option C (Capacity):Monitors link utilization and load, not jitter.
Option D (Switch Health):Monitors device hardware and software health, not traffic performance.

Which component performsVXLAN encapsulation and de-encapsulation?

• A. VLAN
• B. root bridge
• C. VTEP
• D. WXLAN policy

Answer: C

Explanation:
In anEVPN-VXLANarchitecture, theVXLAN Tunnel Endpoint (VTEP)is responsible for encapsulating and de-encapsulating Layer 2 Ethernet frames into VXLAN packets that traverse the IP underlay.
"Each device participating in a VXLAN overlay operates as a VXLAN Tunnel Endpoint (VTEP). The VTEP encapsulates Ethernet frames into VXLAN headers for transmission and de-encapsulates VXLAN packets back into Ethernet frames upon receipt." Option A:Incorrect - VLAN is a Layer 2 construct, not responsible for encapsulation.
Option B:Correct- VTEP handles VXLAN encapsulation and de-encapsulation.
Option C:Incorrect - root bridge pertains to STP, not VXLAN.
Option D:Incorrect - WXLAN policy is not a valid networking term in Juniper documentation.

NEW QUESTION # 56
What are thetwo ways to forward BUM trafficwhen usingEVPN?(Choose two.)

• A. Use underlay replication.
• B. Use static routes.
• C. Use BGP neighborship.
• D. Use ingress replication.

Answer: A,D

Explanation:
InEVPN-VXLAN,BUM (Broadcast, Unknown unicast, and Multicast)traffic is handled differently than unicast traffic. EVPN provides two main forwarding mechanisms to distribute BUM traffic betweenVTEPs (VXLAN Tunnel Endpoints):
"BUM traffic in EVPN-VXLAN fabrics is replicated using eitheringress replicationorunderlay multicast(PIM- based). Both methods ensure that broadcast and unknown unicast frames reach all remote VTEPs within the same VXLAN segment." Option A:Incorrect - static routes are unrelated to BUM forwarding.
Option B:Incorrect - BGP is thecontrol plane, not a data-plane forwarding method.
Option C:Correct-Ingress replicationreplicates BUM packets to all remote VTEPs in the same VNI using unicast tunnels.
Option D:Correct-Underlay replication (multicast)uses multicast groups in the IP underlay to distribute BUM frames efficiently.
