Practise exhibit-style questions that ask you to read a topology, table, command output or diagram before choosing the best answer.
Start Scenario PracticeBased on the exhibit, why are clients in VLAN 70 failing to resolve hostnames even though they can reach remote IP addresses?
Explanation: The strongest explanation is that the clients are missing valid DNS server information. In practical terms, successful reachability to remote IP addresses proves that Layer 3 forwarding is working. The failure occurs only when a hostname is used, which points to a naming service problem rather than a general connectivity problem. The DHCP scope shown provides an address and default gateway, but no DNS server option is defined. This is a very realistic IP-services troubleshooting pattern because the network path works while application usability still fails.
Based on the exhibit, which action is most likely required to allow AP-22 to join the controller successfully?
Explanation: The correct action is to fix the AP's default gateway so it can reach the controller's subnet. Option B is wrong because APs use Ethernet, not PPP encapsulation, which is used for serial WAN links. Option C is wrong because CAPWAP does not assign IP addresses; DHCP does, but the AP already has a static IP, and removing it would cause it to fall back to DHCP, which may not fix the gateway issue. Option D is wrong because disabling DHCP on the controller would affect all APs and prevent new APs from obtaining addresses, which is not a targeted fix.
A switch stack is running PVST+. Users on VLAN 40 lose connectivity for roughly 30 seconds every time the uplink on SW2 flaps. Based on the exhibit, which change would most directly improve convergence for this VLAN?
Explanation: The output shows VLAN 40 is still using the legacy IEEE STP process, which converges much more slowly than Rapid PVST+. Moving the switch to rapid-pvst mode gives VLAN 40 the faster proposal/agreement behavior that typically cuts convergence time from tens of seconds to a few seconds.
Based on the exhibit, why is traffic to host 198.51.100.70 using the OSPF route instead of the static route?
Explanation: The traffic uses the OSPF route because it is the more specific match. In practical terms, the router evaluates destination-prefix specificity before comparing route source preference. The static route points to a broader /24, while the OSPF entry points to a narrower /26 that still contains the destination. Because longest-prefix match comes first, the /26 route wins. This is a good reminder that static routes do not automatically beat dynamic routes when the prefixes are different. Specificity matters first, then source preference only when the prefix length is the same.
Based on the exhibit, why is traffic to 192.168.40.200 using the default route instead of the intended static route?
Explanation: The intended static route is not being used because the next hop for that static route is not reachable from the current routing table. In practical terms, a route can be configured, but the router still needs a way to resolve and forward to the next-hop address. If that next hop is unreachable, the route may not be installed or usable, so traffic falls back to the default route instead. This is a realistic troubleshooting pattern because the configuration line alone can look correct until you compare it with actual reachability.
