Standard and extended access control lists (ACLs) are used to configure security on a router.

The Transport layer receives large data streams from the upper layers and breaks these up into smaller pieces called segments.

The encapsulation method is data, segment, packet, frame, bit.

Internet Control Message Protocol (ICMP) is used to send error messages through the network, but they do not work alone. Every segment or ICMP payload must be encapsulated within an IP datagram (or packet).

A 240 mask is 4 subnet bits and provides 16 subnets, each with 14 hosts. We need more subnets, so let's add subnet bits. One more subnet bit would be a 248 mask. This provides 5 subnet bits (32 subnets) with 3 host bits (6 hosts per subnet). This is the best answer.

To test the local stack on your host, ping the loopback interface of 127.0.0.1.

You can exit setup mode at any time by using the keystroke Ctrl+C.

The enable secret password is case sensitive, so the second option is wrong. To set the enable secret <password>, use the enable secret <password> command from global configuration mode.

Although answer D almost seems right, it is not; the mask is the mask used on the remote network, not the source network. Since there is no number at the end of the static route, it is using the default administrative distance of 1.

The command show ip nat translations will show you the translation table containing all the active NAT entries.

The show ip nat statistics command displays a summary of the NAT configuration as well as counts of active translation types, hits to an existing mapping, misses (causing an attempt to create a mapping), and expired translations.

The command ip nat pool <name> creates the pool that hosts can use to get onto the global Internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224. Option C is wrong because the pool name has a lower case "T" in the pool name. Pool name's are case sensitive.

You can configure NAT three ways on a Cisco router: static, dynamic, and NAT Overload (PAT).

The host on the private network before translation is considered to be an inside local host.

The host on the global network before translation is considered to be an outside local host.

The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps.

The IEEE 802.11b standard provides a maximum data rate of up to only 11Mbps, and you can be around 150 feet, maybe farther, depending on conditions.

Link-local addresses are meant for throwing together a temporary LAN for meetings or a small LAN that is not going to be routed but needs to share and access files and services locally.

Frame Relay, by default, is a non-broadcast multi-access (NBMA) network, which means that broadcasts, such as RIP updates, will not be forwarded across the link by default.

Please do not freak out because ATM is an answer to this question. ATM is not covered in depth on the CCNA exam. PPP is mostly used for dial-up (async) services, but ATM could be used as well, though it typically is not used anymore since PPP is so efficient.
