11. What are two rules for compacting IPv6 addresses? (Choose two.) A. The maximum number of times a double colon can replace a 16-bit segment that consists of all zeroes is two. B. The leading zeroes in any 16-bit segment do not have to be written. C. Every 16-bit segment that consists of all zeroes can be represented with a single ... Full story

1. Refer to the exhibit. Which statement is true about the 6.6.6.0/24 prefix? A. If another path advertises the 6.6.6.0/24 path and has the default local preference, that path is more preferred. B. The command neighbor send-community is configured on BGP neighbor 10.10.23.3. C. The route 10.10.23.3 is not being advertised to other BGP neighbors. ... Full story

Enhanced Interior Gateway Routing Protocol - (EIGRP) is a Cisco proprietary routing protocol loosely based on their original IGRP. EIGRP is an advanced distance-vector routing protocol, with optimizations to minimize both the routing instability incurred after topology changes, as well as the use of bandwidth and processing power in the router. Routers that support EIGRP will automatically redistribute route information to IGRP neighbors by ... Full story

Rapid Spanning Tree Protocol (RSTP; IEEE 802.1w) which provides for faster spanning tree convergence after a topology change, is an evolution of the 802.1D standard more than a revolution. The 802.1D terminology have been unchanged. Most parameters remain the same so that users familiar with 802.1D can rapidly configure the new protocol comfortably. In most situations, RSTP performs ... Full story

As a link state routing protocol, OSPF establishes and maintains neighbor relationships in order to exchange routing updates with other routers. The neighbor relationship table is called an adjacency database in OSPF. Provided that OSPF is configured correctly, OSPF forms neighbor relationships only with the routers directly connected to it. The routers that it forms a neighbor relationship with must be in the same ... Full story

Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the ... Full story
