what is Post Office Protocol 3 (POP3)
This protocol is used to download email from a server, and then delete the email from that server. (Take note that newer clients provide an option to leave messages on the email server)
What Protocol is port 69/udp
TFTP
Intermediate System to Intermediate System (IS-IS)
IS-IS is a link state routing protocol used for routing within an autonomous system. IS-IS uses a relative link cost for metric IS-Is is a classless protocol. The original IS-IS protocol was not used for routing IP packets; use integrated IS-Is to include routing support IS-IS divides a large network into areas. however there is no area 0 requirement like OSPF, and ISIS provides greater flexability than OSPF for creating and connecting areas. L1 routers share routes within an area; L2 routers share routes between areas; an L1/L2 router can share routes with both L1 and L2 routers A network link is the boundary between one area and another area. IS-IS is best suited for large private networks supporting larger networks than OSPF. IS-IS is typically used within an ISP, and easily supports IPv6 routing.

Border Gateway Protocol (BGP)
BGP is an advanced distance vector protocol (also called a path vector protocol) BGP is an exterior gateway protocol. (EGP) used for routing between autonomous systems. BGP uses paths, rules, and policies instead of a metric for making routing decisions BGP is a classless protocol Internal BGP(iBGP) is used within an autonomous system; external BGP (eBGP) is used between Autonomous systems BGP is the protocol used on the internet: ISPs use BGP to identify routes between autonomous systems. Very large networks can use BGP internally, but typically only share routers on the internet if the Autonomous system has two (or more) connections to the internet through different ISPs.
What is Domain Name System (DNS)

Open shortest Path First (OSPF)
OSPF is a link state routing protocol used for routing within an AS. OSPF uses a relative link cost for the metric OSPF is a classless protocol. OSPF divides a large network into areas. Each Autonomous system requires an area 0 that identifies the network backbone. All areas are connected to area 0, either directly or indirectly through another area. Routes between areas must pass through area 0. Internal routers share routes within an area; area border routers share routes between areas; autonomous system boundary routers share routes outside of the autonomous system. A router is the boundary between one area and another area. OSPF is best suited for large private networks
What protocol is port 137/udp
NetBIOS-ns (NETBIOS Name Service)
what protocol is port 53 tcp/udp?
DNS (Dynamic mail server)
what is Secure Socket Layer (SSL)
secures messages being transmitted on the internet. uses RSA for authentication and encryption.
You have a router configured to share routing information using RIP. In addition, you have a single static route that identifies a default route for all other networks. The next hop router for the default route has changed. You need to make the change with the least amount of effort possible. What should you do?
Manually reconfigure the default route to point to the next hop router. Because the route is static, when changes to the network occur, routing table entries must be changed. The default route was configured manually so it must be manually updated
RIP (Routing protocol information)
Rip is a distance vector routing protocol used for routing wihin an autonomous system. Rip uses the hop count as the metric. Rip Networks are limited in size to a maximum of 15 hops between any two networks. a network with a hop count of 16 is an unreachable network Rip v! is a classful protocol; Rip V2 is a classless protocol. Rip is best suited for private networks

Demarc Extension
extends the demarcation point from its original location to another location within the building. The demark extension typically consists of a single wire bundle that attaches to the existing demark and supplies a termination point to a different location. You might need a demark extension if your network occupies an upper floor building. The LEC will typically install the demark into the MDF on the bottom floor, and you will need to install an extension to place the demark into the IDF on your floor. You are typically responsible for installing the demark, extension, or the LEC might do it for an additional charge.
