  1. A

    The outside interface must be configured as ip nat inside.

  2. B

    The router must have an ACL that permits every protocol, regardless of the traffic being tested.

  3. C

    The outside interface must be up and have usable addressing.

  4. D

    The NAT ACL must list the remote destination network as its source.

Two switches use an interswitch trunk, and you suspect a native-VLAN mismatch is causing unexpected traffic handling. Which check is most appropriate?

  1. A

    Configure the native VLAN differently on each end so each switch can identify the other's untagged traffic.

  2. B

    Compare the native VLAN settings on both trunk ends and make them consistent.

  3. C

    Remove VLAN 10 from the allowed list because it exists on both switches.

  4. D

    Configure the link as an access port on one end and a trunk on the other.

Select all accurate statements about DHCP snooping and port trust.

  1. A

    DHCP snooping helps prevent unauthorized DHCP servers from answering clients.

  2. B

    Every client-facing access port should generally be trusted.

  3. C

    Interfaces leading to legitimate DHCP servers or trusted network infrastructure should generally be trusted.

  4. D

    DHCP snooping replaces the need for a DHCP server scope.

Two directly connected routers do not become OSPF neighbors. Select all useful checks to perform before changing the network design.

  1. A

    Verify interface/link state and IP reachability between the routers.

  2. B

    Check that both interfaces use a compatible OSPF area and compatible hello/dead timers and network type.

  3. C

    Change the administrative distance of OSPF before checking interface settings.

  4. D

    Check whether an OSPF interface has been made passive.

  5. E

  1. A

    On the DHCP server's interface facing its own subnet.

  2. B

    On the VLAN 20 router subinterface that receives the clients' broadcasts.

  3. C

    On the switch's VLAN 20 access ports.

  4. D

Hosts in VLAN 10 communicate locally on each switch, but not across the interswitch link. VLAN 10 exists on both switches. Which trunk setting should you check to determine whether VLAN 10 traffic can cross the link?

  1. A

    Confirm that VLAN 10 is configured as the native VLAN on both switches.

  2. B

    Confirm that VLAN 10 is included in the trunk’s allowed-VLAN list.

  3. C

    Assign the trunk port to VLAN 10 as an access port.

  4. D

    Enable DHCP snooping on the trunk.

A network policy should smooth a traffic flow by delaying excess traffic rather than dropping or remarking it. Which QoS action fits this goal?

  1. A

    Classification identifies traffic, while marking schedules it during congestion.

  2. B

    Policing delays excess traffic to smooth the transmission rate.

  3. C

    Shaping delays excess traffic to smooth the transmission rate.

  4. D

    Queuing enforces a rate by dropping or remarking excess traffic.

VLAN 20 clients receive no DHCP lease, while the DHCP server is at 192.168.99.10 on another network. Where should you inspect for the relay setting that forwards VLAN 20 client broadcasts to the server?

  1. A

    Configure ip helper-address 192.168.99.10 on the VLAN 20 router subinterface.

  2. B

    Configure ip helper-address 192.168.99.10 on the DHCP server’s interface.

  3. C

    Configure the helper address on the VLAN 99 switch access ports.

  4. D

    Configure the helper address only on the interswitch trunk.

A router has routes for 10.8.0.0/16 and 10.8.4.0/24. A packet is destined for 10.8.4.25. Which route is selected by longest-prefix match, even if the /16 route has a lower administrative distance?

  1. A

    The 10.8.0.0/16 route, because it covers the larger network.

  2. B

    The route with the lower administrative distance, regardless of prefix length.

  3. C

    The default route, because both listed routes match.

  4. D

    The 10.8.4.0/24 route, because it has the longer prefix.

An extended ACL first denies all IP traffic from 192.168.20.0/24 to 192.168.30.0/24, then permits UDP DNS traffic from 192.168.20.0/24 to 192.168.30.53. To allow the DNS exception while denying other traffic to that subnet, the DNS permit must appear the deny.
