Q1 MultipleChoice

What are three characteristics of VLAN translation?

AVLAN translation is not supported on MC-LAG port channel interfaces.

BTrunk or access ports can be configured as members of any VLANs that are not used as an SVLAN.

CBy default, VLAN stacking is enabled on Z9432F-ON switches.

DThe SVLAN header is replaced with a VNI if the provider network uses a VXLAN overlay.

ESVLAN configuration for both Q-in-Q VLAN tunneling and VLAN translation is possible on the same interface.

Correct Answer: A, B, E

Explanation:

VLAN translation is not supported on MC-LAG port channel interfaces (A): This is a restriction commonly seen in network configurations involving Multi-Chassis Link Aggregation (MC-LAG) where VLAN translation capabilities are not applied.

Trunk or access ports can be configured as members of any VLANs that are not used as an SVLAN (B): This ensures that the VLAN configuration on trunk or access ports is flexible and does not overlap with Service VLANs (SVLANs).

SVLAN configuration for both Q-in-Q VLAN tunneling and VLAN translation is possible on the same interface (E): This allows for complex VLAN tagging and translation configurations to be applied to the same interface, supporting advanced networking scenarios.

Q2 MultipleChoice

What is ECMP?

AA Layer 3 routing feature to forward traffic using multiple available paths

BA routing protocol database filter supporting a maximum of four paths

CA round-robin path distribution mechanism

DA routing protocol with multipath support

Correct Answer: A

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.

Q3 MultipleChoice

Refer to the exhibit.

The router ID has not been manually configured. What router ID is used for Switch 3?

A192.168.100.2

B192.168.100.0

C10.0.2.1

D10.0.1.1

Correct Answer: D

Explanation:

In the absence of a manually configured router ID, OSPF typically uses the highest IP address on the switch's active interfaces. For Switch 3 in the exhibit, the highest IP address is 10.0.1.1 on Loopback 0. Therefore, 10.0.1.1 is used as the router ID for Switch 3.

Q4 MultipleChoice

How many port channels can be assigned to a single port?

A8

B2

C4

D1

Correct Answer: D

Explanation:

According to the Dell SONiC documentation, a single physical port can be a member of only one port channel at a time. This restriction ensures the consistency and integrity of link aggregation configurations.

Q5 MultipleChoice

What is the impact of entering the qos-mode uniform command on a VTEP interface?

AThe DCSP values for the local and remote VTEPs are synchronized.

BThe local VNI value is aligned to the VNI of the remote VTEP interface.

CA uniform VNI value is configured on local and remote VTEP interfaces.

DThe payload DSCP value is copied to the outer header DSCP value.

Correct Answer: D

Explanation:

Entering the qos-mode uniform command on a VTEP interface ensures that the DSCP (Differentiated Services Code Point) value of the payload is copied to the outer header DSCP value. This maintains the Quality of Service (QoS) markings across the VXLAN tunnel, allowing consistent traffic prioritization.
