Q101. – (Topic 2) 

How many simultaneous Telnet sessions does a Cisco router support by default? 

A. 1 

B. 2 

C. 3 

D. 4 

E. 5 

F. 6 



By default, Cisco routers support virtual terminal interfaces 0-4 (5 total) which are used for telnet sessions. 

Q102. – (Topic 1) 

Refer to the exhibit. 

What must be configured to establish a successful connection from Host A to switch SW-A through router RT-A? 

A. VLAN 1 on RT-A 

B. IP routing on SW-A 

C. default gateway on SW-A 

D. crossover cable connecting SW-A and RT-A 



In order for the switch to reach networks that are not local, such as networks attached to different interfaces of the router, it will need to set its default gateway to be the IP address of the attached router. 

Q103. – (Topic 5) 

Including the address on the Routed Ethernet interface, how many hosts can have IP addresses on the LAN to which Routed is connected? 

A. 6 

B. 30 

C. 62 

D. 126 



This is a /29 address, so there are 6 usable IP’s on this subnet. 

Q104. – (Topic 1) 

Refer to the exhibit. 

A network has been planned as shown. Which three statements accurately describe the areas and devices in the network plan? (Choose three.) 

A. Network Device A is a switch. 

B. Network Device B is a switch. 

C. Network Device A is a hub. 

D. Network Device B is a hub. 

E. Area 1 contains a Layer 2 device. 

F. Area 2 contains a Layer 2 device. 

Answer: A,D,E 


Switches use a separate collision domain for each port, so device A must be a switch. Hubs, however, place all ports in the same collision domain so device B is a hub. Switches reside in layer 2 while hubs are layer 1 devices. 

Q105. – (Topic 7) 

Which statement about native VLAN traffic is true? 

A. Cisco Discovery Protocol traffic travels on the native VLAN by default 

B. Traffic on the native VLAN is tagged with 1 by default 

C. Control plane traffic is blocked on the native VLAN. 

D. The native VLAN is typically disabled for security reasons 


Q106. – (Topic 3) 

Refer to the exhibit. 

Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router? 







The highest IP address of all loopback interfaces will be chosen -> Loopback 0 will be chosen as the router ID. 

Q107. – (Topic 1) 

Refer to the exhibit. 

What kind of cable should be used to make each connection that is identified by the numbers shown? 

A. 1 – Ethernet Crossover cable 2 – Ethernet straight-through cable 3 – Fiber Optic cable 4 – Rollover cable 

B. 1 – Ethernet straight-through cable 2 – Ethernet straight-through cable 3 – Serial cable 4 – Rollover cable 

C. 1 – Ethernet rollover cable 2 – Ethernet crossover cable 3 – Serial cable 4 – Null-modem cable 

D. 1 – Ethernet straight-through cable 2 – Ethernet Crossover cable 3 – Serial cable 4 – Rollover cable 

E. 1 – Ethernet straight-through cable 2 – Ethernet Crossover cable 3 – Serial cable 4 – Ethernet Straight-through cable 



When connecting a PC to a switch, a standard Ethernet straight through cable should be used. This same cable should also be used for switch to router connections. Generally 

speaking, crossover cables are only needed when connecting two like devices (PC-PC, 

switch-switch, router-router, etc). 

Routers connect to frame relay and other WAN networks using serial cables. 

Rollover cables are special cables used for connecting to the console ports of Cisco 


Q108. – (Topic 7) 

Which routing protocol has the smallest default administrative distance? 







Explanation: Default Distance Value TableThis table lists the administrative distance default values of the protocols that Cisco supports: 

Route Source Default Distance Values 

Connected interface 0 Static route 1 Enhanced Interior Gateway Routing Protocol (EIGRP) summary route 5 External Border Gateway Protocol (BGP) 20 Internal EIGRP 90 IGRP 100 OSPF 110 Intermediate System-to-Intermediate System (IS-IS) 115 Routing Information Protocol (RIP) 120 Exterior Gateway Protocol (EGP) 140 On Demand Routing (ODR) 160 External EIGRP 170 Internal BGP 200 Unknown* 

Q109. – (Topic 3) 

What is the OSPF default frequency, in seconds, at which a Cisco router sends hello packets on a multi-access network? 

A. 10 

B. 40 

C. 30 

D. 20 



On broadcast multiacess and point-to-point links, the default is 10 seconds. On NBMA, the default is 30 seconds. 

Q110. – (Topic 5) 

Refer to the exhibit. 

The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three.) 

A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports. 

B. Ensure that cables A and B are straight-through cables. 

C. Ensure cable A is plugged into a trunk port. 

D. Ensure the switch has power. 

E. Reboot all of the devices. 

F. Reseat all cables. 

Answer: B,D,F 


The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.
