질문 # 25
What is the purpose of an EPVN Type 4 route?

정답:A

설명:
According to Juniper Networks' EVPN documentation, an EVPN Type 4 route, also known as an Ethernet Segment route, is a critical component of the BGP EVPN control plane used specifically in multihoming scenarios. When a Customer Edge (CE) device is connected to two or more Provider Edge (PE) routers via a Link Aggregation Group (LAG), these PE routers must coordinate to manage traffic flow and prevent network loops.
The primary purpose of the Type 4 route is to enable Designated Forwarder (DF) election. In a multihomed Ethernet Segment (identified by a unique Ethernet Segment Identifier or ESI), only one PE router-the Designated Forwarder-is permitted to forward Broadcast, Unknown unicast, and Multicast (BUM) traffic from the EVPN core to the CE device. Without this election process, multiple PE routers would forward the same BUM packets to the CE, leading to traffic duplication and potential broadcast storms.
The workflow begins when a PE router is configured with an ESI on a physical or logical interface; it then generates and advertises a Type 4 route to all other PE routers in the network. This route carries the ESI and an "ES-import" extended community, which allows other PEs connected to the same segment to automatically discover their peers. Once these "peering" PEs are discovered, they collectively execute a DF election algorithm-such as the default modulo-based algorithm or the newer preference-based algorithm-to select the DF and Backup Forwarder (BDF) for each VLAN or bridge domain. By ensuring a deterministic and synchronized selection of the forwarder, Type 4 routes provide the foundational stability required for active- active and active-standby multihoming in modern campus and data center fabrics.


질문 # 26
You are asked to identify whether your wired network is experiencing issues withjitter.
Which Juniper MistWired Assurance service-level expectation (SLE)metric provides these details?

정답:C

설명:
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.

질문 # 27
In a Juniper Mistcampus fabric deploymentusingEVPN-VXLAN, which component performs the VXLAN encapsulation and de-encapsulation functions?

정답:C

설명:
Comprehensive and Detailed Explanation From Exact Extract:
InEVPN-VXLANarchitectures, theVXLAN Tunnel Endpoint (VTEP)is the logical interface responsible for encapsulating and de-encapsulating Layer 2 Ethernet frames into VXLAN packets.
Each participating switch - typically the access or distribution node - hosts aVTEPthat maps local VLANs to VXLAN Network Identifiers (VNIs).
When a packet leaves a local VLAN, the VTEP encapsulates it in a VXLAN header and routes it through the underlay IP fabric.
When received at the destination VTEP, the frame is de-encapsulated and delivered to the appropriate local VLAN.
"VTEPs in an EVPN-VXLAN campus fabric perform MAC-to-VNI mapping and encapsulate/decapsulate traffic between virtualized network segments, allowing seamless Layer 2 and Layer 3 connectivity across an IP underlay." References:
