Question 100

At North Library, an IDF trunk carries voice VLAN 310 but its upstream interface mistakenly permits only data VLAN 110. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Restrict sensitive management details on ports where topology advertisement is inappropriate.
  2. Record VLAN allowlists and avoid a global all-VLAN trunk as a shortcut.
  3. Validate compatible PoE class switch power budget and negotiated per-port allocation.
  4. Permit the required 802.1Q VLAN tags at both trunk ends and map the correct native VLAN.

Explanation

Correct Answers

B:

This is the continuing risk-control element for North Library. Record VLAN allowlists and avoid a global all-VLAN trunk as a shortcut prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

D:

This is the implementation element for the North Library case: 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links. The specific action Permit the required 802.1Q VLAN tags at both trunk ends and map the correct native VLAN addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for LLDP topology and discovery: LLDP supplies adjacent-device identity without proving end-to-end routing or authentication. It does not resolve the 802.1Q VLAN tagging requirement in North Library and is not one of the two controls requested. The direct mechanism here is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

C:

This may be a configuration step for PoE power negotiation: 802.3af at and bt power classes and the switch budget constrain device operation. It does not resolve the 802.1Q VLAN tagging requirement in North Library and is not one of the two controls requested. The direct mechanism here is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links
