JNCIS-DC: Juniper Networks Certified Specialist – Data Center — Question 4

Which two statements correctly describe an extended service set (ESS)? (Choose two.)

Answer options

• A. Each BSS within the ESS share a common BSSID.
• B. Each BSS within the ESS has its own unique BSSID.
• C. The SSID is common across all BSSs within the ESS.
• D. The SSID is unique across all BSSs within the ESS.

Correct answer: B, C

Explanation

Option B is correct because each Basic Service Set (BSS) within an ESS does indeed have its own unique BSSID. Option C is also correct because the SSID is shared among all BSSs in the ESS, allowing devices to connect seamlessly. Options A and D are incorrect as they misrepresent the relationship between BSSIDs and SSIDs in an ESS.
