  Disabling Dynamic Trunking Protocol (DTP)

  Cisco's Dynamic Trunking Protocol can facilitate the automatic creation of trunks between two switches. When two connected ports are configured in dynamic mode, and at least one of the ports is configured as desirable, the two switches will

  negotiate the formation of a trunk across the link. DTP isn't to be confused with VLAN Trunking Protocol (VTP), although the VTP domain does come into play.

  

  DTP on the wire is pretty simple, essentially only advertising the VTP domain, the status of the interface, and it's DTP type. These packets are transmitted in the native (or access) VLAN every 60 seconds both natively and with ISL encapsulation (tagged as VLAN 1) when DTP is enabled.

• Question 553:

  What are two enhancements that OSPFv3 supports over OSPFv2? (Choose two.)

  A. It requires the use of ARP.
  B. It can support multiple IPv6 subnets on a single link.
  C. It supports up to 2 instances of OSPFv3 over a common link.
  D. It routes over links rather than over networks.
  B. It can support multiple IPv6 subnets on a single link.
  D. It routes over links rather than over networks.

• Question 554:

  which effect does the switchport trunk native vlan 10 command have?

  A. It allows traffic from native VLAN 10 on the trunk
  B. It prevents traffic on VLAN 1 from passing on the trunk
  C. It sets VLAN 10 as the native VLAN on the trunk
  D. It configures the interface as a trunk port
  C. It sets VLAN 10 as the native VLAN on the trunk

• Question 555:

  Refer to the exhibit.

  

  Which command is simplest to configure routing between the regional office network 10.89.0.0/20 and the corporate network?

  A. router2(config)#ip route 0.0.0.0 0.0.0.0 10.89.16.1
  B. router2(config)#ip route 10.89.3.0 255.255.0.0 10.89.16.2
  C. router1(config)#ip route 10.89.0.0 255.255.240.0 10.89.16.1
  D. router1(config)#ip route 10.89.0.0 255.255.240.0 10.89.16.2
  A. router2(config)#ip route 0.0.0.0 0.0.0.0 10.89.16.1

• Question 556:

  Refer to the exhibit.

  

  C-router is to be used as a "router-on-a-stick" to route between the VLANs. All the interfaces have been properly configured and IP routing is operational. The hosts in the VLANs have been configured with the appropriate default gateway. What is true about this configuration?

  A. These commands need to be added to the configuration: C-router(config)# router eigrp 123 C-router(config-router)# network 172.19.0.0
  B. These commands need to be added to the configuration: C-router(config)# router ospf 1 C-router(config-router)# network 172.19.0.0 0.0.3.255 area 0
  C. These commands need to be added to the configuration: C-router(config)# router rip C-router(config-router)# network 172.19.0.0
  D. No further routing configuration is required.
  D. No further routing configuration is required.

  Since all the same router (C-router) is the default gateway for all three VLANs, all traffic destined to a different VLA will be sent to the C-router. The C-router will have knowledge of all three networks since they will appear as directly connected in the routing table. Since the C-router already knows how to get to all three networks, no routing protocols need to be configured.

• Question 557:

  Which two benefits are provided by using a hierarchical addressing network addressing scheme? (Choose two.)

  A. reduces routing table entries
  B. auto-negotiation of media rates
  C. efficient utilization of MAC addresses
  D. dedicated communications between devices
  E. ease of management and troubleshooting
  A. reduces routing table entries
  E. ease of management and troubleshooting

  Here are some of the benefits of hierarchical addressing:

  Reduced number of routing table entries -- whether it is with your Internet routers or your internal routers, you should try to keep your routing tables as small as possible by using route summarization. Route summarization is a way of having a

  single IP address represent a collection of IP addresses; this is most easily accomplished when you employ a hierarchical addressing plan. By summarizing routes, you can keep your routing table entries (on the routers that receive the

  summarized routes) manageable, which offers the following benefits:

  Efficient allocation of addresses--Hierarchical addressing lets you take advantage of all possible addresses because you group them contiguously.
