Cisco 100-101 Online Questions & Answers

• Question 81:

  Refer to the exhibit.

  

  The network administrator made the entries that are shown and then saved the configuration. From a console connection, what password or password sequence is required for the administrator to access privileged mode on Router1?

  A. cisco
  B. sanfran
  C. sanjose
  D. either cisco or sanfran
  E. either cisco or sanjose
  F. sanjose and sanfran
  B. sanfran

  ---

  The enable secret password takes precedence over the enable password, so sanfran will be used.

• Question 82:

  How does TCP differ from UDP? (Choose two.)

  A. TCP provides best effort delivery.
  B. TCP provides synchronized communication.
  C. TCP segments are essentially datagrams.
  D. TCP provides sequence numbering of packets.
  E. TCP uses broadcast delivery.
  B. TCP provides synchronized communication.
  D. TCP provides sequence numbering of packets.

• Question 83:

  What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

  A. 2
  B. 8
  C. 16
  D. unlimited
  B. 8

  ---

  Maximum-paths (OSPF)

  To control the maximum number of parallel routes that Open Shortest Path First (OSPF) can maximum-paths command. support, use the Syntax Description

  maximum Maximum number of parallel routes that OSPF can install in a routing table. The range is from 1 to 16 routes.

  Command Default paths

• Question 84:

  How can you ensure that only the MAC address of a server is allowed by switch port Fa0/1?

  A. Configure port Fa0/1 to accept connections only from the static IP address of the server.
  B. Configure the server MAC address as a static entry of port security.
  C. Use a proprietary connector type on Fa0/1 that is incomputable with other host connectors.
  D. Bind the IP address of the server to its MAC address on the switch to prevent other hosts from spoofing the server IP address.
  B. Configure the server MAC address as a static entry of port security.

  ---

  When the MAC address is configured as static entry, no other address is allowed.

• Question 85:

  Which statements accurately describe CDP? (Choose three.)

  A. CDP is an IEEE standard protocol.
  B. CDP is a Cisco proprietary protocol.
  C. CDP is a datalink layer protocol.
  D. CDP is a network layer protocol.
  E. CDP can discover directly connected neighboring Cisco devices.
  F. CDP can discover Cisco devices that are not directly connected.
  B. CDP is a Cisco proprietary protocol.
  C. CDP is a datalink layer protocol.
  E. CDP can discover directly connected neighboring Cisco devices.

  ---

  CDP (Cisco Discovery Protocol) is a proprietary protocol designed by Cisco to help administrators collect information about both locally attached and remote devices. By using CDP, you can gather hardware and protocol information about neighbor devices containing useful info for troubleshooting and documenting the network.

• Question 86:

  Which statement about IPv6 is true?

  A. Addresses are not hierarchical and are assigned at random.
  B. Only one IPv6 address can exist on a given interface.
  C. There are 2.7 billion addresses available.
  D. Broadcasts have been eliminated and replaced with multicasts.
  D. Broadcasts have been eliminated and replaced with multicasts.

  IPv6 has three types of addresses, which can be categorized by type and scope:

  Unicast addresses. A packet is delivered to one interface. Multicast addresses. A packet is delivered to multiple interfaces. Anycast addresses. A packet is delivered to the nearest of multiple interfaces (in terms of routing distance).

  IPv6 does not use broadcast messages.

  Unicast and anycast addresses in IPv6 have the following scopes (for multicast addresses, the scope are built into the address structure):

  Link-local. The scope is the local link (nodes on the same subnet). Site-local. The scope is the organization (private site addressing). Global. The scope is global (IPv6 Internet addresses). In addition, IPv6 has special addresses such as the

  loopback address. The scope of a special address depends on the type of special address.

  Much of the IPv6 address space is unassigned.

• Question 87:

  Refer to the exhibit.

  

  The output is from a router in a large enterprise. From the output, determine the role of the router.

  A. A Core router.
  B. The HQ Internet gateway router.
  C. The WAN router at the central site.
  D. Remote stub router at a remote site.
  D. Remote stub router at a remote site.

• Question 88:

  What information can be used by a router running a link-state protocol to build and maintain its topological database? (Choose two.)

  A. hello packets
  B. SAP messages sent by other routers
  C. LSAs from other routers
  D. beacons received on point-to-point links
  E. routing tables received from other link-state routers
  F. TTL packets from designated routers
  A. hello packets
  C. LSAs from other routers

  Link state protocols, sometimes called shortest path first or distributed database protocols, are built around a well-known algorithm from graph theory, E. W. Dijkstra'a shortest path algorithm.

  Examples of link state routing protocols are:

  Open Shortest Path First (OSPF) for IP

  The ISO's Intermediate System to Intermediate System (IS-IS) for CLNS and IP DEC's DNA Phase V Novell's NetWare Link Services Protocol (NLSP)

  Although link state protocols are rightly considered more complex than distance vector protocols, the basic functionality is not complex at all:

  1.

  Each router establishes a relationship--an adjacency--with each of its neighbors.

  2.

  Each router sends link state advertisements (LSAs), some

  3.

  Each router stores a copy of all the LSAs it has seen in a database. If all works well, the databases in all routers should be identical.

  4.

  The completed topological database, also called the link state database, describes a graph of the internetwork. Using the Dijkstra algorithm, each router calculates the shortest path to each network and enters this information into the route table.

• Question 89:

  An administrator is in the process of changing the configuration of a router. What command will allow the administrator to check the changes that have been made prior to saving the new configuration?

  A. Router# show startup-config
  B. Router# show current-config
  C. Router# show running-config
  D. Router# show memory
  E. Router# show flash
  F. Router# show processes
  C. Router# show running-config

  ---

  This command followed by the appropriate parameter will show the running config hence the admin will be able to see what changes have been made, and then they can be saved.

• Question 90:

  

  

  The hosts in the LAN are not able to connect to the Internet. Which commands will correct this issue?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  E. Option E
  F. Option F
  B. Option B

  ---

  Do a "show ip int brief" and you will see that Fa0/1 has an IP address assigned, but it is shut down.
