One of the drawbacks of NAT is that it might disrupt services that require the initiation of TCP connections from the outside network or disrupt stateless protocols, such as those using UDP. Why is NAT disruptive in these two cases? Inbound (outside to inside connections) depend on the presence of NAT mapping to be forwarded to the receiving host inside the network. NAT mappings can time out and, therefore, prevent the device from translating the incoming packets, which end up discarded. TCP connections require three-way handshake to be completed. NAT allows initial TCP segment, which has flags SYN and ACK set to pass only from the inside to the outside and not from the outside to the inside. NAT does not translate ackets for protocols that do not establish connections and do not maintain the state of the connections. For applications that use UDP, NAT always translates both IPv4 address and port number. Since UDP applications can use whatever port number, it is impossible to make mappings for all; therefore, NAT translations will not happen and UDP segments get discarded.

You configured an important host in your company with a static default gateway pointing to one of the routers in the network. You also have a second router that can provide connectivity to other subnets. What will happen when the primary router fails and there is only a dynamic routing protocol configured between the routers? The host will automatically discover the failure and update its default gateway with the IP address of the second router. The second router will use the dynamic routing protocol to instruct the host to change its default gateway with its IP address. The host should have DHCP provide the default gateway, so the DHCP server can dynamically update the gateway after the failure. The host will lose connection to other subnets, since it cannot dynamically update the default gateway.

In which mechanism can a device be configured with a private IPv4 address but communicate on the internet using a globally routable IPv4 address? * NAT * VLSM * ARP multihoming

In which mechanism can a device be configured with a private IPv4 address but communicate on the internet using a globally routable IPv4 address? NAT The correct answer is "NAT." NAT breaks the end-to-end model of IP. NAT introduced a model in which a device that is facing outward to the internet has a globally routable IPv4 address, while the internal network is configured with private addresses. These private addresses can never leave the site, so they can be identical in many different enterprise networks.

Regarding trunk ports, which statement is true? * The show vlan command can be used to check trunk ports on a switch. * The native VLAN on a trunk port is tagged. * All VLANs are sent untagged on a trunk port. * By default, all VLANs are allowed on a trunk.

Regarding trunk ports, which statement is true? By default, all VLANs are allowed on a trunk. If you do not explicitly allow VLANs to traverse the trunk, all will be allowed to cross the link. By default the native VLAN is VLAN 1, and it is untagged by default. All the other VLANs that are traversing the trunk are tagged. If you use the show vlan command, you will not see any trunk ports in the output. In this case, it is better to use the show interfaces trunk command.

The administrator has configured an EtherChannel link between switches SW1 and SW2. His configuration is shown in the exhibit. However, the EtherChannel does not form. What is the likely reason for the issue? The configurations do not use the same channel-group number. The configurations do not form between the same interfaces—SW1 is bundling ports FastEthernet 0/1 and 0/2, while SW2 is bundling ports FastEthernet 0/4 and 0/5. Logical interfaces cannot be trunks. The trunk configuration on the switches is not consistent.

The administrator wants to allow only PC1 to have remote access to the file server, using SSH. Other devices from the 192.168.10.0/24 network should not be allowed SSH remote access, but other traffic should be permitted. Where would you place this access list for most efficient implementation? - router R1, interface Gi0/0 out - router R1, interface Gi0/1 in - router R1, interface Gi0/2 out - router R3, interface Gi0/0 in - router R2, interface Gi0/0 out - router R2, interface Gi0/1 out - router R3, interface Gi0/1 out

(Choose two.) * Place unused ports into VLAN 1. * Administratively shut down the unused ports. * Create a black hole VLAN, and place unused ports into that VLAN. * Configure unused ports as trunk ports. * Place unused ports into a VLAN that has access to the internet.

Your boss asked you to secure the unused switch ports on a switch that resides on a 2nd floor. Which two options are recommended as best practice? (Choose two.) * Administratively shut down the unused ports. * Create a black hole VLAN, and place unused ports into that VLAN. A good security practice is to configure all the ports on all switches to be associated with VLANs other than VLAN 1. Also, all unused switch ports should be assigned to black hole VLAN and set to be administratively down. A black hole VLAN is a term for a VLAN, which has no route, or no default-gateway to other networks within your organization, or to the internet.
