关于VRRP,下列说法正确的是()。A.Master定期发送VRRP报文,如果Backup长时间没有收到报文,则将自己状态改为MasterB.Backup定期发送VRRP报文,如果Master收到Backup来的报文,比较优先级,确定是否将自己状态设定为Master或者BackupC.若有多台Backup,则根据发送的VRRP报文,选举优先级最大成为新的MasterD.在备份容错协议中,还有一种HSRP协议,此协议除了报文结构和VRRP不一样外,类的报文交互方式等全部都是一致的

Refer to the exhibit. There are two sites connected across WAN links. All intersite and intrasite links always have the same routing metric. The network administrator sees only the top routers and links being used by hosts at both LAN A and LAN B. What would be two suggestions to load-balance the traffic across both WAN links?()A、 Make HSRP track interfaces between the edge and core routers.B、 Replace HSRP with GLBP. 用GLBP替换HSRPC、 Add crossed intrasite links: R1-R4, R2-R3, R5-R8, and R6-R7.D、 Make R3 and R8 have lower HSRP priority than R1 and R7.E、 Replace HSRP with VRRP

TippingPoint被设计成无IP地址和MAC地址的设备,所以TippingPoint本身不可能独立支持主备倒换,它的主备倒换要借助于其它的协议,这些协议有VRRP、OSPF、CARP、HSRP等。()
You need to decide on the best router redundancy protocol to use in the Company network. Which two statements are true about HSRP, VRRP, and GLBP?()A、 GLBP and VRRP allow for MD5 authentication, whereas HSRP does not.B、 HSRP allows for multiple upstream active links being simultaneously used, whereas GLBP does not.C、 GLBP allows for router load balancing of traffic from a network segment without the different host IP configurations required to achieve the same results with HSRP.D、 Unlike HSRP and VRRP, GLBP allows automatic selection and simultaneous use of multiple available gateways.E、 GLBP allows for router load balancing of traffic from a network segment by utilizing the creation of multiple standby groups.
What are two characteristics of GSS?()A、It helps verify end-to-end path availability.B、It provides traffic rerouting in case of disaster.C、HSRP, GLBP, and VRRP can be clients of GSS.D、BGP must be the routing protocol between the distributed data centers.E、DNS responsiveness is improved by providing centralized domain management.
For the following protocols, which one provides a mechanism to transparently intercept and redirect CIFS traffic from a client to a local Cisco Wida Area Application engine?()A、Virtual Router Redundancy Protocol(VRRP)B、File Transport Protocol(FTP)C、Hot Standby Routing Protocol(HSRP)D、Web Cache Communication Protocol(WCCP)
多选题You need to decide on the best router redundancy protocol to use in the Company network.
