Questions — 40

  1. A 2.4 GHz deployment must reduce adjacent-channel overlap across three nearby APs using 20 MHz channels in the US. Which set is appropriate?
  2. A branch needs 50 usable IPv4 addresses per VLAN. Which prefix provides the smallest conventional subnet that meets this requirement?
  3. A Cisco ACL ends with several permit statements but no catch-all permit. What happens to a packet matching none of them?
  4. A controller separates network policy decisions from device packet forwarding. Which concept does this illustrate?
  5. A DHCP client has no valid IPv4 address. Which message normally begins its address-allocation exchange?
  6. A DHCP server is on another routed subnet. Which router function forwards client discovery traffic to it?
  7. A four-link EtherChannel has one physical member configured in a different access VLAN. What is the likely outcome?
  8. A full-duplex Ethernet link experiences many late collisions after a configuration change. What should be investigated first?
  9. A host is 192.0.2.78/27. Which address is in the same subnet and usable by another host?
  10. A router forwards traffic to fe80::2 on an Ethernet link. What additional information is needed for an unambiguous next hop?
  11. A router has no specific destination match and no default route. What happens to an ordinary transit IPv4 packet?
  12. A routing table has 10.0.0.0/8 via A and 10.20.0.0/16 via B. Where is 10.20.8.5 forwarded?
  13. A script needs to retrieve a controller's current device inventory through a REST API. Which HTTP method is normally appropriate?
  14. A static backup route must remain unused while an OSPF route to the same prefix exists. What should be configured?
  15. A static route points to an unreachable next hop with no recursive route resolving it. Why is it absent from the routing table?
  16. A switch has the lowest bridge priority and lowest MAC among peers in one STP instance. What role should it obtain?
  17. A switch receives a frame from MAC 00aa.bbcc.0010 on port Gi1/0/8. What information populates its MAC table?
  18. A switch receives a unicast frame whose destination MAC is absent from its table. What does it do by default?
  19. A wireless network requires per-user enterprise authentication. Which design is most appropriate?
  20. A workstation must reach another IPv4 subnet. Which MAC address normally appears as the destination in its first Ethernet frame?
  21. An administrator must replace cleartext remote CLI access. Which option provides encrypted remote management?
  22. An AI assistant proposes a new switch configuration from natural-language instructions. What is the best next step before production rollout?
  23. An API returns {"enabled":true,"ports":[1,2]}. Which statement correctly interprets this JSON?
  24. An attacker sends forged DHCP offers from an access port. Which control identifies permitted DHCP server-facing ports?
  25. An employee connects an unauthorized switch to a PortFast port. Which feature can shut the port when it receives a BPDU?
  26. An endpoint-only access port takes too long to forward after link-up. Which feature is appropriate with suitable protections?
  27. An extended ACL should block only TCP traffic from 10.1.1.0/24 to a server's port 443. Which fields are necessary?
  28. An office port should allow only two learned endpoint MAC addresses. Which feature is the best fit?
  29. An OSPF router must advertise a user LAN but never form neighbors on that LAN. Which configuration approach is suitable?
  30. Hosts use a redundant virtual default gateway. Which benefit does a first-hop redundancy protocol provide?
  31. Many internal IPv4 hosts share one public IPv4 address for outbound TCP sessions. Which feature distinguishes their flows?
  32. On a broadcast OSPF segment, a router's interface priority is zero. What does that mean?
  33. OSPF neighbors remain down after the hello interval is changed on only one peer. What is the best correction?
  34. Security logs from two routers show the same event several minutes apart. Which service should be checked first?
  35. The same /24 prefix is learned through OSPF and a normal static route. Which is preferred with default Cisco administrative distances?
  36. Two OSPF routers on the same subnet use different area IDs. What prevents adjacency?
  37. Two switches connect through an 802.1Q trunk. VLAN 30 works locally but not across switches. What should be checked first?
  38. Two switches must form an LACP channel without a proprietary negotiation protocol. Which pairing negotiates successfully?
  39. Two trunk ends use different native VLANs. What is the primary risk?
  40. Which two statements about IPv6 are correct? Select 2 answers.
