Route 10.42.91.0/24 has a tag of 28160. The reported distance of 10.0.0.0/8 is 0. Route 10.42.88.0/21 has an administrative distance of 28160. Each route has only one best path.

Which value must you configure on a device before EIGRP for IPv6 can start running?. public IP address. loopback interface. router ID. process ID.

Which two statements about link-state routing protocols are true? (Choose two.). Link-state routing protocols use split horizon to avoid routing loops. Each router determines its own path to a destination. Each router maintains its own unique routing database. Each router shares a database of known routes. Each router is aware only of its neighbor routers.

Refer to the exhibit. Which of these statements correctly describes the state of the switch once the boot process has been completed?. The switch will need a different IOS code in order to support VLANs and ST. Remote access management of this switch will not be possible without configuration change. As FastEthernet0/12 will be the last to come up, it will be blocked by STP. More VLANs will need to be created for this switch.

Which effete does the aaa new-model coniguration commandhave?. It enables AAA services on the device. It configures the device to connect to a RADIUS server for AAA. It associates a RADIUS server to an AAA group. It configures a local user on the device.

Which two statements about DNS lookup operations are true? (Choose two). They use destination port 53. When the primary IP address of the destination is down, the DNS server can forward the client to an alternative IP address. The client sends a request for IP address to domain name resolution to the DNS server. The client sends a request for domain name to IP address resolution to the DNS server. The DNS server pings the destination to verify that is available.

Which two criteria must be met to support the ICMP echo IP SLA? (Choose two). The destination device must support the echo protocol. default gateway must be configured for the source and destination devices. The source device must be running Layer 2 services. The source and destination devices must be Cisco devices. The source device must be a Cisco device but the destination device can be from any vendor.

Which two advantages do dynamic routing protocols provide over static routing? (Choose two.). Dynamic routing requires fewer resources than static routing. Only dynamic routing is supported on all topologies that require multiple routers. Dynamic routing protocols are easier to manage on very large networks ITExamAnswers.net.
