Question 1

Which of the following is a general-purpose protocol that provides WAN data link encapsulation services similar to those available for LAN encapsulations?

Accepted Answer

Point-to-Point Protocol (PPP) is a data link layer (Layer 2) communication protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption (using ECP, RFC 1968), and compression. PPP is used over many types of physical networks including serial cable, phone line, trunk line, cellular telephone, specialized radio links, and fiber optic links such as SONET. It is designed to work with various network layer protocols, including Internet Protocol (IP), making it a general-purpose data link encapsulation service suitable for use over WAN links.

Question 2

The method distance vector protocols use to prevent packets from endlessly circulating around a routing loop is called ____________________.

Question 3

Which configuration option allows a router to watch for traffic on its LAN that does not match its own IP address, so the router can add entries for that traffic in its ARP cache and routing table?

Accepted Answer

Local Area Mobility allows a router to monitor traffic within its LAN that doesn't match its own IP address. This feature enables the router to update its ARP cache and routing table with information about the observed traffic, facilitating more efficient routing and communication within the network.

Question 9

Protocols at which layer of the OSI model have the primary function of moving datagrams through an internetwork connected by routers?

Accepted Answer

The primary function of protocols at the Network layer (Layer 3) of the OSI model is to move datagrams through an internetwork connected by routers. This layer is responsible for logical addressing and routing, enabling data to traverse multiple networks from the source to the destination.

Question 14

The default TTL in Windows Server 2008, Windows Server 2012, Windows 7, and Windows 10 is which of the following?

Accepted Answer

The default Time To Live (TTL) value for IP packets in Windows Server 2008, Windows Server 2012, Windows 7, and Windows 10 is 128. This value determines the maximum number of hops an IP packet can travel before being discarded.

Question 15

What method is used to obtain an IP address for an associated data link address?

Accepted Answer

Reverse Address Resolution Protocol (RARP) is used to obtain an IP address for a given hardware (data link) address, such as a MAC address, on a local network. This is particularly useful for diskless workstations that may not know their IP address upon booting.
