NEW QUESTION # 23
Enterprise SONiC Switch 1 and Switch 2 are part of a symmetric VXLAN fabric in a data center environment.
Switch 1 has learned MAC addresses from its local VLANs.
What role does BGP EVPN play in this scenario?
- A. Enables efficient communication across the VXLAN fabric
- B. Distributes locally learned MAC addresses to Switch 2
- C. Establishes Layer 2 connectivity between Switch 1 and Switch 2
Answer: B
Explanation:
BGP EVPN (Border Gateway Protocol Ethernet VPN) is used in a VXLAN fabric to distribute MAC address reachability information between switches. In this scenario, Switch 1 uses BGP EVPN to advertise the locally learned MAC addresses to Switch 2. This distribution of MAC addresses enables the switches to build and maintain an efficient forwarding table, facilitating communication across the VXLAN fabric.

NEW QUESTION # 25
Refer to the exhibit.
What is the primary VRRP router for VRRP group 10?
- A. Router-3
- B. Router-1
- C. Router-2
Answer: C
Explanation:
Based on the exhibit, Router-2 has the highest priority (90) in VRRP group 10. In VRRP, the router with the highest priority becomes the primary (master) router. Therefore, Router-2 is the primary VRRP router for VRRP group 10.

NEW QUESTION # 30
Refer to the exhibit.
What can be determined from this show command?
- A. There is a 10% probability that traffic is marked as congested
- B. ECN is enabled for all colors
- C. ECN is enabled for all DSCP values
- D. Traffic below 100 KB is marked as congested
Answer: B
Explanation:
The output of the command show qos wred-policy pfc34 shows the ECN (Explicit Congestion Notification) configuration for the policy pfc34. The line ecn: ecn_all indicates that ECN is enabled for all traffic classes (all DSCP values). Additionally, the green-min-threshold, green-max-threshold, and green-drop-probability settings are shown, but there is no indication of a 10% probability for marking traffic as congested. Therefore, the correct answer is B.

NEW QUESTION # 31
What is an iBGP neighbor relationship?
- A. Two BGP neighbors share L2VPN EVPN advertisements.
- B. Two BGP neighbors share only private networks.
- C. Two BGP neighbors share only native BGP networks.
- D. Two BGP neighbors have the same autonomous system numbers
Answer: D
Explanation:
An iBGP (Internal Border Gateway Protocol) neighbor relationship is established between two BGP routers within the same autonomous system (AS). This relationship allows for the exchange of routing information within the AS, ensuring that internal routes are propagated correctly.

NEW QUESTION # 32
An administrator for a service provider uses this command on a switch:
What is the result of running the command?
- A. Maps the VLAN traffic that a CVLAN identifies to a VNI on a VTEP
- B. Maps the VLAN traffic that an SVLAN identifies to a VNI on a VTEP
- C. Maps the VLAN traffic that a TPID identifies to a VNI on a VTEP
Answer: B
Explanation:
The command interface vxlan vtep-stacking followed by map vni 10010 vlan 100 maps the VLAN traffic that an SVLAN identifies to a VNI on a VTEP. In this context, SVLAN (Service VLAN) is being mapped to a VXLAN Network Identifier (VNI) for encapsulation and transport across the VXLAN tunnel.

NEW QUESTION # 33
What interface must be selected when configuring the management port from within the MF-CLI environment?
- A. ma 0/1
- B. mgmt 1/1/1
- C. eth0
- D. Management 0
Answer: C
Explanation:
* Dell SONiC Management Interface Configuration:
* In Dell SONiC, the management port configuration is a crucial aspect that allows administrators to access and manage the network device.
* The management interface typically provides out-of-band management access to the device, ensuring that even if the data network is down, the management network can still be accessed.
* Common Interface Naming Conventions:
* mgmt 1/1/1: This naming convention is not typically used in Dell SONiC environments for management interfaces.
* ma 0/1: This could be a potential naming convention but is not standard for Dell SONiC.
* Management 0: This is a logical name but does not align with the standard interface naming conventions used in Dell SONiC.
* eth0: This is the standard naming convention used for the primary management interface in most Linux-based systems, including Dell SONiC.
* Verification with Dell SONiC Documentation:
* Dell SONiC documentation specifies that the management interface is usually named eth0.
* When accessing the management interface within the MF-CLI (Management Framework Command Line Interface) environment, eth0 is the correct interface to configure.
* Practical Configuration Example:
* When configuring the management port, the command might look something like:
config interface ip add eth0 <management_ip_address>/<subnet_mask>
* This command specifies the management interface eth0 and assigns it an IP address for network management purposes.
References:
* Dell Enterprise SONiC Deployment Guide
* Dell Technologies Networking - SONiC
This detailed step-by-step explanation confirms that the correct answer is D, providing insights into the typical interface naming conventions and configuration practices within the Dell SONiC environment.
NEW QUESTION # 34
Which two elements are configured when RoCE is enabled?
- A. ETS
- B. TCP
- C. IB
- D. PFC
Answer: A,D
Explanation:
When RDMA over Converged Ethernet (RoCE) is enabled, Enhanced Transmission Selection (ETS) and Priority Flow Control (PFC) are two key elements that need to be configured. ETS allows for bandwidth allocation among different traffic classes, and PFC provides lossless Ethernet operation for specific traffic classes to support low-latency, high-performance network communication.

NEW QUESTION # 35
What is ECMP?
- A. A routing protocol with multipath support
- B. A round-robin path distribution mechanism
- C. A routing protocol database filter supporting a maximum of four paths
- D. A Layer 3 routing feature to forward traffic using multiple available paths
Answer: D
Explanation:
ECMP (Equal-Cost Multi-Path) is a Layer 3 routing feature that allows traffic to be forwarded using multiple available paths of equal cost. This improves bandwidth utilization and provides redundancy. ECMP is commonly used in modern networks to optimize the flow of traffic and increase the resiliency of network connections.

NEW QUESTION # 36
Which network devices route unencapsulated user traffic in a symmetric IRB overlay network?
- A. Capability extended next hop router and leaf router
- B. Leaf router and spine router
- C. Source VTEP and destination VTEP
- D. Autonomous system boundary router and source VTEP
Answer: C
Explanation:
In a symmetric Integrated Routing and Bridging (IRB) overlay network, the Source Virtual Tunnel End Point (VTEP) and the Destination VTEP route unencapsulated user traffic. Symmetric IRB ensures that routing occurs at both the ingress and egress VTEPs, allowing for optimized traffic flow and efficient network operations.

NEW QUESTION # 38
Which two things does the no vrrp 100 address-family ipv6 command delete?
- A. Address-family
- B. Version
- C. Identifier
- D. Authentication
- E. Interface
Answer: A,C
Explanation:
The no vrrp 100 address-family ipv6 command deletes the VRRP (Virtual Router Redundancy Protocol) identifier (A) and the address-family configuration (D) for VRRP group 100. This effectively removes the VRRP configuration for the specified address family.
