QuestionQ1

SONiC Configuration

Which modes are supported by the QSFP28 ports on an S5248F?

Explanation

The S5248F QSFP28 interfaces support operation as one 100-GbE port, one 40-GbE port, two 50-GbE breakout interfaces, or four 25-GbE breakout interfaces. The 200-GbE and 400-GbE modes apply to higher-capacity port technologies, not standard QSFP28 ports.

QuestionQ2

SONiC Configuration

Which three characteristics describe VLAN translation?

Choose three
Explanation

VLAN translation is unsupported on MC-LAG port-channel interfaces. Trunk and access ports may belong to VLANs that are not designated as S-VLANs, and an interface can have S-VLAN configuration for both Q-in-Q VLAN tunneling and VLAN translation. On Z9432F-ON, VLAN stacking must be enabled before VLAN translation is used; with a VXLAN overlay, the S-VLAN is mapped to a VNI.

QuestionQ4

VXLAN

Refer to the exhibit.

Question Image

The route distinguisher was generated automatically. Which VLAN is mapped to VNI 410?

Explanation

VNI 410 is the Layer 2 VXLAN segment associated with VLAN 10. An automatically derived EVPN route distinguisher identifies the MAC-VRF and must not be interpreted as the VNI or as a VLAN number; the automatically derived route target, by contrast, carries the VNI value.

QuestionQ5

VXLAN

Enterprise SONiC Switch 1 and Switch 2 are components of a symmetric VXLAN fabric in a data-center environment. Switch 1 has learned MAC addresses from its local VLANs.

What is the role of BGP EVPN in this scenario?

Explanation

BGP EVPN distributes locally learned MAC reachability information through EVPN MAC/IP Advertisement routes to other participating switches. This enables Switch 2 to install reachability information for MAC addresses learned by Switch 1.

QuestionQ6

SONiC Configuration

How many port channels may be assigned to one port?

Explanation

A physical interface can be a member of only one port channel at a time, because a port channel is the interface’s single logical link-aggregation membership.
