E7 The OSPF process is configured incorrectly on Router1

E> There is an incorrect wildcard mask statement for network 10.10.0.0/16 on Router2

Using default settings, what is the next step in the router boot sequence after the IOS loads from flash?

Perform the POST routine

Search for a backup IOS in ROM

Load the bootstrap program from ROM

Load the running-config file from RAM

AO Locate and load the startup-config file from NVRAM

Trang 3

5 Which statement is true regarding routing metrics?

All routing protocols use the same metrics

EIGRP uses bandwidth as its only metric

Routers compare metrics to determine the best route

enOnene The larger metric generally represents the better path

Trang 4

Which path will be used to transmit the data packets between PC1 and PC22

The packets will travel via R2-R1

The packets will travel via R2-R3

The traffic will be load-balanced between two paths — via R2-R1 and via R2-R3

The packets will travel via R2-R3, and the other path via R2-R1 will be retained as the backup path

11 A compary Is using static routes that are configured with an administrative distance of “1” on all routers in the network The network administrator decides to introduce a dynamic routing protocol to reduce the manual configurations for the static routes Which option identifies the correct procedure for the dynamic routing to take place in the network?

[° The static routes and the dynamic routes will have the traffic alternate between them

E The static routes will be automatically removed once the dynamic routing is configured

E The static routes will be automatically updated with the next hop IP address once the dynamic routing is configured

E The static routes must be manually removed from all routers in order for the dynamic routes to be installed in the routing table

Routert 192.1.1.65/26

The network shown in the diagram is having problems routing traffic It is suspected that the problem is with the addressing scheme What is the problem with the addressing used in the topology?

Router1 is a broadcast address for that subnetwork

The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to EthernetO The subnetwork assigned to the SerialO interface of Router1 is on a different subnetwork from the address for Serial0 of Router2 The subnetwork assigned to EthernetO of Router2 overlaps with the subnetwork assigned to Ethernet0O of Routers

31 What does RIP use to reduce convergence time in a larger network?

It uses multicast instead of broadcast to send routing updates

It reduces the update timer to 15 seconds if there are more than 10 routes

It uses triggered updates to announce network changes if they happen in between the periodic updates

eonenene It uses random pings to detect if a pathway is down and therefore is preemptive on finding networks that are down

3alf a router is booting with its default configuration register setting and its NVRAM lacks boot system commands, from where will the

~ router try to load the IOS image first?

The router maintains the same source and destination IP

The router changes the source physical address to the physical address of the exit interface

The router changes the destination IP to the IP of the exit interface

| the same process ID

| the same area ID

' network addresses and wildcard masks

| the same router ID

| the same loop back address
