Refer to exhibits 1 and 2. In exhibit 1, all users on the LAN segment use router A as the active HSRP router. Router B is the standby router for the HSRP. In exhibit 2, the network management team reported that there is no utilization on the WAN link B. To solve this problem, you decide to change the logical topology of your LAN, but you are not sure about what changes must be made. You must manage HSRP or change it to another protocol in order to provide the most scalable design, automatic redundancy, and load balancing. Which one of these actions would be the best choice? ()

A. Use MHSRP, with three users using router A as the default gateway and three users using router B as the default gateway.
B. Keep HSRP and activate PBR to redirect half of the traffic to the other WAN link.
C. Use the backup interface on the WAN link B to provide load balancing for all users.
D. Use GLBP instead, because it provides you with up to three MAC addresses for the same default gateway virtual IP address.
E. Use GLBP instead, because it provides you with up to four MAC addresses for the same default gateway virtual IP address.

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.

A.It is used in multihome network scenarios.
B.It can be used with BGP to mitigate DoS and DDoS.
C.It does not need to have CEF enabled.
D.It is enabled via the interface level command ip verify unicast reverse-path.
E.It cannot be used with "classification" access lists.

5.單項(xiàng)選擇題What does Cisco recommend when you are enabling Cisco IOS IPS?()

A.Do not enable all the signatures at the same time.
B.Do not enable the ICMP signature.
C.Disable the Zone-Based Policy Firewall because it is not compatible with Cisco IOS IPS.
D.Disable CEF because it is not compatible with Cisco IOS IPS. .
