  Port Roles

  The role is now a variable assigned to a given port. The root port and designated port roles remain, while the blocking port role is split into the backup and alternate port roles. The Spanning Tree Algorithm (STA) determines the role of a port

  based on Bridge Protocol Data Units (BPDUs). In order to simplify matters, the thing to remember about a BPDU is there is always a method to compare any two of them and decide whether one is more useful than the other. This is based on

  the value stored in the BPDU and occasionally on the port on which they are received. This considered, the information in this section explains practical approaches to port roles.

  Compatibility with 802.1D

  RSTP is able to interoperate with legacy STP protocols. However, it is important to note that the inherent fast convergence benefits of 802.1w are lost when it interacts with legacy bridges.

  Understanding IPv6 Link Local Address Reference: http://www.cisco.com/en/US/tech/tk872/technologies_configuration_example09186a0080ba1d07.shtml

  The purpose of this document is to provide an understanding of IPv6 Link-local address in a network. A linklocal address is an IPv6 unicast address that can be automatically configured on any interface using the linklocal prefix FE80::/10 (1111 1110 10) and the interface identifier in the modified EUI-64 format. Link-local addresses are not necessarily bound to the MAC address (configured in a EUI-64 format). Link-local addresses can also be manually configured in the FE80::/10 format using the ipv6 address link-local command.

• Question 33:

  Which three statements about HSRP operation are true? (Choose three.)

  A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.
  B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
  C. HSRP supports only clear-text authentication.
  D. The HSRP virtual IP address must be on a different subnet than the routers' interfaces on the same LAN.
  E. The HSRP virtual IP address must be the same as one of the router's interface addresses on the LAN.
  F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.
  A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.
  B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
  F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.

• Question 34:

  Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.) Router(config)# router ospf 1

  A. All OSPF routers in an area must have the same process ID.
  B. Only one process number can be used on the same router.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.
  E. Hello packets are sent to each neighbor to determine the processor identifier.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.

  ---

  we all know that The areas can be any number from 0 to 4.2 billion and 1 to 65,535 for the Process ID. The process ID is the ID of the OSPF process to which the interface belongs. The process ID is local to the router, and two OSPF neighboring routers can have different OSPF process IDs. (This is not true of Enhanced Interior Gateway Routing Protocol [EIGRP], in which the routers need to be in the same autonomous system). Cisco IOS Software can run multiple OSPF processes on the same router, and the process ID merely distinguishes one process from the another. The process ID should be a positive integer.

  Open Shortest Path First Reference: http://docwiki.cisco.com/wiki/Open_Shortest_Path_First Additional OSPF features include equal-cost, multipath routing, and routing based on upper- layer type-of-service (TOS) requests. TOS-based routing supports those upper-layer protocols that can specify particular types of service. An application, for example, might specify that certain data is urgent. If OSPF has high- priority links at its disposal, these can be used to transport the urgent datagram. OSPF supports one or more metrics. If only one metric is used, it is considered to be arbitrary, and TOS is not supported. If more than one metric is used, TOS is optionally supported through the use of a separate metric (and, therefore, a separate routing table) for each of the eight combinations created by the three IP TOS bits (the delay, throughput, and reliability bits). For example, if the IP TOS bits specify low delay, low throughput, and high reliability, OSPF calculates routes to all destinations based on this TOS designation. IP subnet masks are included with each advertised destination, enabling variable-length subnet masks. With variable- length subnet masks, an IP network can be broken into many subnets of various sizes. This provides network administrators with extra network-configuration flexibility.

• Question 37:

  Refer to the exhibit.

  

  A packet with a source IP address of 192.168.2.4 and a destination IP address of 10.1.1.4 arrives at the AcmeB router. What action does the router take?

  A. forwards the received packet out the Serial0/0 interface
  B. forwards a packet containing an EIGRP advertisement out the Serial0/1 interface
  C. forwards a packet containing an ICMP message out the FastEthemet0/0 interface
  D. forwards a packet containing an ARP request out the FastEthemet0/1 interface
  C. forwards a packet containing an ICMP message out the FastEthemet0/0 interface

  CCNA - EIGRP Common Question http://www.orbitco-ccna-pastquestions.com/CCNA---EIGRP-Common-Question.php

  Looking at the output above, there is no IP route for 10.1.1.4 address on AcmeB routing table. If the router can no find a specific path in its routing table to a particular route,( In this case no path is found so AcmeB) the router will inform the source host with an ICMP message that the destination is unreachable and this will be through the same interface it has received the packet (interface Fa0/0 network 192.168.3.0/28 from the exhibit).

• Question 38:

  Which protocol is an open standard protocol framework that is commonly used in VPNs, to provide secure end-to-end communications?

  A. RSA
  B. L2TP
  C. IPsec
  D. PPTP
  C. IPsec

  ---

  Internet Protocol Security (IPsec) is a technology protocol suite for securing Internet Protocol (IP) communications by authenticating and/or encrypting each IP packet of a communication session. IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session.

• Question 39:

  What is the advantage of using a multipoint interface instead of point-to-point subinterfaces when configuring a Frame Relay hub in a hub-and-spoke topology?

  A. It avoids split-horizon issues with distance vector routing protocols.
  B. IP addresses can be conserved if VLSM is not being used for subnetting.
  C. A multipoint interface offers greater security compared to point-to-point subinterface configurations.
  D. The multiple IP network addresses required for a multipoint interface provide greater addressing flexibility over point-to-point configurations.
  B. IP addresses can be conserved if VLSM is not being used for subnetting.

  ---

  You do not have to assign a separate subnet per sub-interface .if you're using a Class A network (10.x.x.x/8), you blow the whole network on a few connections (if you used VLSM, you could use a better mask, limit the addresses used). if you used 10.0.0.0/8, you would not be assigning the entire /8 to a single network. You would select a subnet mask for the network and then, you would have to use that mask with all subnets of the network. So if you chose a /24 mask, that would mean that you would have to use a /24 mask for even point-to-point links.

• Question 40:

  

  

  A static map to the S-AMER location is required. Which command should be used to create this map?

  A. frame-relay map ip 172.30.0.3 825 broadcast
  B. frame-relay map ip 172.30.0.3 230 broadcast
  C. frame-relay map ip 172.30.0.3 694 broadcast
  D. frame-relay map ip 172.30.0.3 387 broadcast
  B. frame-relay map ip 172.30.0.3 230 broadcast

  ---

  Frame-relay map ip 172.30.0.3 230 broadcast

  172.30.0.3 is S-AMER router ip address and its configure on 230 dlci value. Check "show frame-relay map " output in the diagram.
