  IP Routing Table Entry TypesAn entry in the IP routing table contains the following information in the order presented:

  Network ID. The network ID or destination corresponding to the route. The network ID can be class-based, subnet, or supernet network ID, or an IP address for a host route. Network Mask. The mask that is used to match a destination IP

  address to the network ID.

  Next Hop. The IP address of the next hop.

  Interface. An indication of which network interface is used to forward the IP packet. Metric. A number used to indicate the cost of the route so the best route among possible multiple routes to the same destination can be selected. A common

  use of the metric is to indicate the number of hops (routers crossed) to the network ID. Routing table entries can be used to store the following types of routes:

  Directly Attached Network IDs. Routes for network IDs that are directly attached. For directly attached networks, the Next Hop field can be blank or contain the IP address of the interface on that network. Remote Network IDs. Routes for

  network IDs that are not directly attached but are available across other routers. For remote networks, the Next Hop field is the IP address of a local router in between the forwarding node and the remote network. Host Routes. A route to a

  specific IP address. Host routes allow routing to occur on a per- IP address basis. For host routes, the network ID is the IP address of the specified host and the network mask is 255.255.255.255. Default Route. The default route is designed

  to be used when a more specific network ID or host route is not found. The default route network ID is 0.0.0.0 with the network mask of 0.0.0.0.

• Question 63:

  Refer to the exhibit.

  

  Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to interface E0 inbound, to prevent all hosts (except those whose addresses are the first and last IP of subnet 172.21.1.128/28) from accessing the network. But as is, the ACL does not restrict anyone from the network. How can the ACL statements be re-arranged so that the system works as intended?

  A. ACDB
  B. BADC
  C. DBAC
  D. CDBA
  D. CDBA

  Routers go line by line through an access list until a match is found and then will not look any further, even if a more specific of better match is found later on in the access list. So, it it best to begin with the most specific entries first, in this cast the two hosts in line C and D. Then, include the subnet (B) and then finally the rest of the traffic (A).

• Question 64:

  Which command enables RSTP on a switch?

  A. spanning-tree uplinkfast
  B. spanning-tree mode rapid-pvst
  C. spanning-tree backbonefast
  D. spanning-tree mode mst
  B. spanning-tree mode rapid-pvst

  Rapid Spanning Tree Protocol (RSTP) is an enhancement of the original STP 802.1D protocol. The RSTP 802.1w protocol is an IEEE open implementation. Cisco has its own proprietary implementation of RSTP, that includes the benefits of

  its Per-VLAN spanning tree protocols, called Rapid-PVST+.

  To activate the Rapid-PVST+ protocol:

  switch(config)#spanning-tree mode rapid-pvst

• Question 65:

  Which type of attack can be mitigated by configuring the default native vlan to be unused ?

  A. swich spoofing
  B. cam table overflow
  C. vlan hopping
  D. MAC spoofing
  C. vlan hopping

• Question 66:

  In a switched environment, what does the IEEE 802.1Q standard describe?

  A. the operation of VTP
  B. a method of VLAN trunking
  C. an approach to wireless LAN communication
  D. the process for root bridge selection
  E. VLAN pruning
  B. a method of VLAN trunking

  ---

  A broadcast domain must sometimes exist on more than one switch in the network. To accomplish this, one switch must send frames to another switch and indicate which VLAN a particular frame belongs to. On Cisco switches, a trunk link is created to accomplish this VLAN identification. ISL and IEEE 802.1Q are different methods of putting a VLAN identifier in a Layer 2 frame. The IEEE 802.1Q protocol interconnects VLANs between multiple switches, routers, and servers. With 802.1Q, a network administrator can define a VLAN topology to span multiple physical devices. Cisco switches support IEEE 802.1Q for FastEthernet and Gigabit Ethernet interfaces. An 802.1Q trunk link provides VLAN identification by adding a 4-byte tag to an Ethernet Frame as it leaves a trunk port.

• Question 67:

  Drag and drop

  Select and Place:

  

  

• Question 68:

  Which statement about a router on a stick is true?

  A. Its date plane router traffic for a single VI AN over two or more switches.
  B. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs on the same subnet.
  C. It requires the native VLAN to be disabled.
  D. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs.
  D. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs.
