Which two benefits does using virtual PortChannel technology provide? (Choose two). A. vPC eliminates spanning-tree blocked ports. B. vPC allows a dual-homed server to operate in active-standby mode. C. vPC significantly reduces latency. D. vPC uses all uplink bandwidth. E.…
You must measure the amount of traffic that a mobile packet gateway produces when mobile phones access the service provider’s internal applications, rather than the Internet. Backbone queuing can be properly designed as a result of this analysis. This traffic…
You are a network designer who must fine tune the convergence of an IS-IS network. The failure detection mechanism has been addressed with reliable loss-of-signal at the interface level. Which three other tools or techniques should be employed to achieve…
To improve the stability of the network and protect it from intrusions, you must design control plane security. Which two features should you enable as part of this design? (Choose two.) A. SNMP security B. uRPF C. IPsec D. IP…
You are auditing the network design of a PIM BiDir multicast network. Which option is the most appropriate multicast group source discovery design consideration for this design? A. A phantom RP advertises the multicast group sources. B. Source discovery is…
The network architect wants to reduce the OSPF database in the network by using summarization techniques. In which two places in the network can summarization be applied to maximum effect? (Choose two.) A. on the OSPF links of all ABR…
Which technique can be used to deploy IPv6 services in an IPv4-only routed backbone network? A. NAT64 at the peering locations B. 6PE in the backbone network C. 6RD on CE routers and 6RD border relays at the peering locations…
Which two mechanisms can anycast RPs use to share multicast state information with other RPs? (Choose two.) A. MSDP B. PIM anycast RP sets C. IGMPv3 D. MLD E. static mroutes
In a routed access hierarchical campus design, the access-to-distribution Layer 2 uplink trunks are replaced with Layer 3 point-to-point routed links. Why is it recommended that VLANs are confined on a single access switch rather than span across multiple access…
The Database team will deploy a new clustering technology that uses IPv4, multicast-based data replication, where the servers listen and transmit at the same time on multiple groups. Multicast is not being run on the current network and there are…
