Dell EMC Specialist – Systems Administrator, VNX — Question 13

Which configuration supports tagged frames on VLAN 20 and untagged frames on VLAN 5?

Answer options

• A. interface ethernet 1/1/9 switchport trunk mode allowed vlan 20 switchport access mode vlan 5 no shutdown
• B. interface ethernet 1/1/9 switchport trunk allowed vlan 20 switchport access vlan 5 switchport mode trunk
• C. interface ethernet 1/1/9 switchport trunk mode allowed vlan 20 switchport access vlan 5 no shutdown
• D. interface ethernet 1/1/9 switchport mode trunk switchport trunk allowed vlan 20 switchport access vlan 5

Correct answer: D

Explanation

Option D is correct because it configures the interface to operate in trunk mode, allowing VLAN 20 to send tagged frames while permitting VLAN 5 to send untagged frames. Options A and C incorrectly specify 'mode' and 'access mode', which are not valid configurations. Option B does not set the interface to trunk mode, which is necessary to support tagged frames.
