• Question 804:

  What are three benefits of implementing VLANs? (Choose three.)

  A. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
  B. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.
  C. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
  D. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.
  E. Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.
  F. VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain.
  G. Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.
  A. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
  C. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
  D. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.

  Benefits of VLANs VLAN is a network structure which allows users to communicate while in different locations by sharing one multicast domain and a single broadcast. They provide numerous networking benefits and have become popular in the market. For instance, it helps reduce administrative costs when users are geographically dispersed.

  1.

  Inexpensive

  The popularity of VLANs is due to the fact that changes, adds, and moves can be attained simply by making necessary configurations on the VLAN port. Time-consuming, re- addressing, and host reconfigurations is now a thing of the past,

  because network configuration can be made at ease when need arises.

  2.

  Better management

  A VLAN typically solve the scalability issues that exist in a large network by breaking the main domain into several VLAN groups or smaller broadcast configurations, thereby encourage better control of multicast traffic as well as broadcast

  domains.

  3.

  Improves network security

  High-security can be positioned in different VLAN groups to ensure that non-members cannot receive their broadcasts. On the other hand, a router is added and workgroups relocated into centralized locations.

  4.

  Enhances performance

  A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.

  5.

  Segment multiple networks

  VLANs are typically used to achieve multiple purposes. They are popularly used to reduce broadcast traffic. Each VLAN creates a separate, smaller broadcast domain.

  6.

  Better administration

  VLANs facilitate grouping of multiple geographical stations. When VLAN users move to another physical location, the network does not have to be configured.

• Question 805:

  

  Refer to the exhibit.If all routers on this network run RIPv2,which configuration should you apply to router R3 to produce this routing table ?

  A. router rip network 192.168.3.0 network 192.168.4.0 network 192.168.23.0 passive-interface default router rip
  B. version 2 network 192.168.3.0 network 192.168.4.0 network 192.168.23.0 distance 70 passive-interface default router rip
  C. version 2 network 192.168.3.0 network 192.168.4.0 network 192.168.23.0 distance 50
  D. router rip version 2 network 192.168.3.0 network 192.168.23.0 distance 50
  D. router rip version 2 network 192.168.3.0 network 192.168.23.0 distance 50

• Question 806:

  Which two commands can you use to troubleshoot DHCP issues? (Choose two)

  A. service dhcp
  B. ip helper-address
  C. clear ip route dhcp
  D. show ip route dhcp
  E. show ip name-server
  A. service dhcp
  B. ip helper-address

• Question 807:

  What are two characteristics of Frame Relay point-to-point subinterfaces? (Choose two.)

  A. They create split-horizon issues.
  B. They require a unique subnet within a routing domain.
  C. They emulate leased lines.
  D. They are ideal for full-mesh topologies.
  E. They require the use of NBMA options when using OSPF.
  B. They require a unique subnet within a routing domain.
  C. They emulate leased lines.

  ---

  Subinterfaces are used for point to point frame relay connections, emulating virtual point to point leased lines. Each subinterface requires a unique IP address/subnet. Remember, you cannot assign multiple interfaces in a router that belong to the same IP subnet.

• Question 809:

  Which two authentic methods are compatible with MLPPP on a serial Interface?(choose two)

  A. PEAP
  B. CHAP
  C. TACACS+
  D. PAP
  E. LEAP
  B. CHAP
  D. PAP
