單項選擇題

Refer to the exhibit. When applying this hierarchical policy map on the on the tunnel1 interface， you measure high jitter for traffic going through class 1234. What is the most likely cause of this jitter？（）

A.The configuration of a hierarchical policy map on a tunnel interface is not supported.
B.Class 5555 and class 5554 are both taking up 100% of the bandwidth， leaving nothing for class 1234.
C.The burst size for the traffic shaping is wrongly configured to 15000； this would require an interface capable of sending at 150Mb/s.
D.The burst size for the traffic shaping has been wrongly configured； it should be set as low as possible.
E.The burst size for the traffic shaping has been wrongly configured； it should be set as high as possible.

3.多項選擇題Your company is researching a new application that runs over IPv6，but part of it must still have IPv4 support. Your company uses a traditional IPv4 network. Your plan is not to run IPv6 over the whole network，but to segment parts of the network or even to operate simultaneously with IPv6 and IPv4. You must make a brief presentation about IPv6 technology to the board of technical directors. Which three of these items could be part of your presentation？ （）

A.Tunnel IPv6 over IPv4 to connect far-end IPv6 networks.
B.Explain why configuring IPv4 and IPv6 at the same time over the same LAN interface is not possible.
C.Explain why configuring IPv4 and IPv6 at the same time over the same LAN interface is possible.
D.What is the meaning of EUI-64 and how does it work？
E.Tunnel IPv4 over IPv6 to connect far-end IPv4 networks.

5.單項選擇題An expanding company is deploying leased lines between its main site and two remote sites. The bandwidth of the leased lines is 128kb/s each， terminated on different serial interfaces on the main router. These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs， and has therefore reserved sufficient bandwidth in a low latency queue on each interface for the VOIP traffic. Users now complain about bad voice quality although no drops are observed in the low latency queue.What action will likely fix this problem？（）

A.mark VOIP traffic with IP precedence 6 and configure only ’fair-queue’ on the links
B.configure the scheduler allocate 3000 1000 command to allow the QoS code to have enough CPU cycles
C.enable class-based traffic shaping on the VoIP traffic class
D.enable Layer 2 fragmentation and interleaving on the links
E.enable Frame Relay on the links and send voice and data on different Frame Relay PVCs

9.多項選擇題

Refer to the exhibit. The Layer 2 network uses VTP to manage its VLAN database. A network designer created all VLANs on the VTP server （switch 1） and it has been advertised through VTP to all other VTP clients （switches 2 through 4）. Due to network growth，a network operator decided to add a new switch between switch 1 and switch 3. The network operator has been instructed to use a refurbished switch and use a VTP client. Which three of these factors should the network operator consider to minimize the impact of adding a new switch？（）

A.Pay special attention to the VTP revision number， because the higher value takes the priority.
B.Configure all VLANs manually on the new switch in order to avoid connectivity issues.
C.A trunk should be established between the new switch and switches 1 and 3 as VTP only runs over trunk links.
D.Set at least the VTP domain name and password to get the new switch synchronized.
E.An ISL trunk should be established between the new switch and switches 1 and 3，because VTP only runs over ISL.
F.Pay special attention to the VTP revision number， because the lower value takes the priority.
