You have been alerted that TCP traffic leaving an interface has been reduced to near zero, while UDP traffic is steadily increasing at the same time. What is this behavior called and what causes it? A. jitter, caused by lack of QoS B. latency, caused by the MTU C. starvation, caused improper configuration of QoS […]

Examine the following output. What possible reason(s) can cause the state of the first entry in the adjacency table? (Choose all that apply.) A. the interface is a multipoint interface B. the clear ip arp command was executed C. the Layer 3 information is unknown D. the clear adjacency command was executed Explanation: If either […]

Which of the following statements represent characteristics of an automatic 6to4 tunnel through an IPv4 network? (Choose all that apply.) A. There is a NAT-PT router on either end of the tunnel. B. There is a dual stack router on either end of the tunnel. C. Each 6to4 site will have a /48 prefix. D. […]

An enterprise has implemented an IPv4 addressing scheme on the servers of its core network. To effectively handle the increasing user requests to the server, the enterprise has plans to implement three new subnets with IPv6 addressing in its existing IPv4 network. The network administrator has set up dual-stack routers on the boundary of these […]

Which of the following IPv6/IPv4 interoperability techniques routes both IP versions simultaneously? A. NAT-PT B. Dual stack C. 6to4 tunnels D. Teredo Explanation: When the routers in the network are capable of routing both IPv6 and IPv4 traffic, it is referred to as dual stack. The dual stack routers simply recognize the version a frame […]

Examine the following FIB table: Which of the following statements is NOT true? A. These are the default entries in an FIB table B. No IP addresses have been configured on this router C. Multicast routing is enabled D. The gateway of last resort has not been set Explanation: The Forwarding Information Base (FIB) table […]

Which dialer interface command sets the maximum size of IP packets to 1492? A. router(config-if)# mtu 1492 B. router(config-if)# ip ppp 1492 C. router(config-if)# ip 1492 D. router(config-if)# ip mtu 1492 Explanation: The correct interface command to set the maximum size of IP packets (maximum transmission unit or MTU size) to 1492 is router(config-if)# ip […]

Which of the following statements are TRUE about manually configured IPV4-to-IP6 tunnels and GRE tunnels? (Choose two.) A. Manually configured tunnels use the tunnel mode ipv6ip command, while GRE tunnels use the tunnel mode gre ip command. B. Manually configured tunnels support IPv6 IGPs, while GRE tunnels do not. C. Manually configured tunnels block IPv6 […]

You have implemented an automatic 6-to-4 tunnel between the routers rtrA and rtrB as shown in the following network diagram: The routers rtrA and rtrB are connected to two IPv6 subnets and are separated by an IPv4 network. You decide to verify whether the tunnel was correctly implemented using the show running-config command. Which of […]
