NEW QUESTION # 100
Exhibit.
Referring to the exhibit, why is the active source field blank for the entry that uses the 00:0c:29:e8:b7:39 MAC address?
Answer: A
Explanation:
In this scenario, the active source field is blank for the MAC address 00:0c:29:e8:b7:39, indicating an issue with how this MAC entry is being processed within the EVPN/VXLAN environment.
Step-by-Step Analysis:
* Understanding the MAC Entry:
* The active source field should normally indicate the source of the route advertisement for a specific MAC address within the EVPN. If it is blank, it suggests that there is a problem with how this entry is being learned or propagated.
* Possible Issues:
* Option A:If the EVPN route for this MAC address does not have a valid next hop, the entry might exist in the MAC table, but it will not have a valid path for forwarding, leading to a blank active source.
* Option B:If the ARP lookup had failed, the entry might not even appear in the MAC table.
However, the entry does exist, suggesting that ARP is not the primary issue here.
* Option C:If the host were locally connected, the active source should reflect a local interface, but the field is blank, ruling out local connection as the cause.
* Option D:Multicast EVPN routes typically do not appear in this manner in the MAC table, and this would not cause the active source to be blank.
Conclusion:The most logical explanation is that the EVPN route for this host exists but does not have a valid next hop, leading to the absence of an active source. This is consistent with how EVPN routing tables work in a VXLAN environment, where the lack of a valid next hop would prevent proper route advertisement and forwarding for the specific MAC address.
NEW QUESTION # 101
You have a sample configuration for connecting two sites through EVPN-VXLAN by exchanging IP prefix routes.
Referring to the exhibit, which two statements regarding the configuration are true? (Choose two.)
Answer: B,D
Explanation:
The configuration provided in the exhibit shows an EVPN-VXLAN setup where IP prefix routes are exchanged between two sites. The advertise direct-nexthop option and the VNI (Virtual Network Identifier) settings are crucial in this context.
Option A: The advertise direct-nexthop option ensures that the next-hop route is resolved using only the information carried in the EVPN Type 5 route. Type 5 routes are used for IP prefix advertisement in EVPN, which is key to enabling Layer 3 interconnectivity between different VXLAN segments.
VNI Consistency:
Option C: For the same customer across different devices, the VNI must be consistent. This consistency ensures that all devices can correctly map traffic to the appropriate VXLAN segment, maintaining seamless Layer 2 and Layer 3 connectivity.
NEW QUESTION # 102
Exhibit.
Referring to the exhibit, when Host A sends an ARP request for Host B's IP address, which Junos feature does leaf1 require to send an ARP response back to Host A without having to send a broadcast frame over the fabric?
Answer: B
Explanation:
* Scenario Overview:
* In the exhibit, Host A is trying to resolve Host B's IP address (10.10.1.2) through ARP (Address Resolution Protocol). Normally, an ARP request would be broadcasted over the network, and the host owning the IP address (Host B) would respond.
* Role of Proxy ARP:
* Option A:Proxy ARPallows a router or switch (in this case, leaf1) to respond to ARP requests on behalf of another host. Leaf1, knowing the MAC address of Host B through the EVPN MAC advertisement, can reply to Host A's ARP request directly without broadcasting the request across the entire network fabric. This feature reduces unnecessary traffic and increases network efficiency.
Conclusion:
* Option A:Correct-Proxy ARP enables leaf1 to respond to Host A's ARP request for Host B's IP without broadcasting over the IP fabric, thus providing the ARP response locally.
NEW QUESTION # 103
You are designing a DCI solution and want to prevent the extension of BUM traffic and Ethernet Segment information between data centers while still allowing IP prefix reachability. Which EVPN seamless stitching type should you use?
Answer: A
Explanation:
When only Layer 3 reachability between data centers is desired, and Layer 2 extension along with associated BUM traffic and Ethernet Segment routes should not cross the DCI, a Type 5 (IP Prefix route) only interconnect is used. Border leaf devices exchange only EVPN Type 5 routes across the DCI, providing inter-subnet routing between data centers while keeping each data center's Layer 2 broadcast domain isolated.
NEW QUESTION # 104
You are preparing an sFlow monitoring system configuration. In this scenario, what Information will be included in the datagram sent to the sFlow collector? (Choose two.)
Answer: B,C
Explanation:
sFlow is a packet sampling technology used to monitor traffic in a network. It sends sampled packet data and interface counters to an sFlow collector, which analyzes the traffic patterns.
Option A: The datagram sent to the sFlow collector includes information about the interface through which the packets entered the agent (the switch or router). This is crucial for understanding where in the network the traffic was captured.
Option D: sFlow datagrams also include the source and destination VLAN for the sampled packets. This allows for detailed analysis of the traffic flow within different VLANs.
