CCNA 3:Module 6

Options With Highlight Colours are Correct Answer 1. Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.) This design will not scale easily. The router merges the VLANs into a single broadcast domain. This design uses more switch and router ports than are necessary. This design exceeds the maximum number of VLANs that can be attached to a switch. This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router. If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router. 2. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance? Implement a router-on-a-stick configuration. Add a second router to handle the inter-VLAN traffic. Use a hub t

CCNA 3:Module 7

Options With Highlight Colours are Correct Answer 1. Which two conditions have favored adoption of 802.11g over 802.11a? (Choose two.) 802.11a suffers from a shorter range than 802.11g. The 2.4 GHz frequency band is not as crowded as the 5 GHz band. 802.11a is more susceptible to RF interference from common commercial items. 802.11a uses a more expensive modulation technique than 802.11g. 802.11g is backward compatible with 802.11b, but 802.11a is not. 2. Which two statements concerning network security are accurate? (Choose two.) 802.11i uses 3DES for encryption. Open authentication uses no client or AP verification. The 802.11i protocol is functionally identical to WPA. 802.11i incorporates a RADIUS server for enterprise authentication. A wireless client first associates with an AP and then authenticates for network access. 3. Which installation method will allow connectivity for a new wireless network? set up WEP on the access point only set up open access on both the access point a

CCNA 2 - Module 1

If a router cannot find a valid configuration file during the startup sequence, what will occur? The router will prompt the user for a response to enter setup mode. Refer to the exhibit. The network administrator has configured the router with the interface IP addresses shown for the directly connected networks. Pings from the router to hosts on the connected networks or pings between router interfaces are not working. What is the most likely problem? The interfaces must be enabled with the no shutdown command. Refer to the exhibit. What can be concluded from the routing table output in the exhibit? (Choose two.) The FastEthernet0/0 and Serial0/0/0 interfaces of this router were configured with an IP address and the no shutdown command. An IP packet received by this router with a destination address of 198.18.9.1 will be forwarded out of the Serial0/0/0 interface. Refer to the exhibit. The frame shown in the exhibit was received by the router. The router interfaces are operational. How

Which of the following are displayed by the Router# show cdp neighbors command? (Choose three.) platform holdtime local interface Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network? In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address. The output of the Router# show interfaces serial 0/1 command displays the following: Serial0/1 is up, line protocol is down. What is the most likely cause for the line protocol being down? No clock rate has been set. A static route that points to the next hop IP will have what administrative distance and metric in the routing table? administrative distance of 1 and metric of 0 Refer to the exhibit. What two commands will change the next-hop address for the 10.0.0.0/8 network from 172.16.40.2 to 192.168.1.2? (Choose two.) A(config)# no ip route 10.0.0.0 255.0.0.0 172.16.40.2 A(config)# ip route 10.0.0.0 255.

CCNA 2 - Module 3

Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.) Administrative distance refers to the trustworthiness of a particular route. Routes with the smallest metric to a destination indicate the best path. Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2? R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP. Which two statements are true regarding classless routing protocols? (Choose two.) sends subnet mask information in routing updates allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology Which command would the network administrator issue to determine if load balancing is in effect on a router? show ip route Which statement is true regarding routing protocols? EIGRP uses DUAL to calculate the shortest path and can be configured to do unequal cost load balancing. Which two co

CCNA 2 - Module 4

Which event will cause a triggered update? a route is installed in the routing table Three routers running a distance-vector routing protocol lost all power, including the battery backups. When the routers reload, what will happen? They will send updates that include only directly connected routes to their directly connected neighbors. What does the RIP holddown timer do? instructs routers to ignore updates, for a specified time or event, about possible inaccessible routes Which two statements are true regarding the function of the RIPv1 routing updates? (Choose two). updates are broadcast at regular intervals broadcasts are sent to 255.255.255.255 Which of the following statements are correct about RIP? will send out an update if there is a failure of a link Which two statements describe EIGRP? (Choose two.) EIGRP sends triggered updates whenever there is a change in topology that influences the routing information. EIGRP sends a partial routing table update, which includes just r

CCNA 2 - Module 5 Refer to the exhibit. The network that is shown is running RIPv1. The 192.168.10.0/24 network was recently added and will only contain end users. What command or set of commands should be entered on Router1 to prevent RIPv1 updates from being sent to the end user devices on the new network while still allowing this new network to be advertised to other routers? Router1(config-router)# passive-interface fastethernet 0/0 The following line was displayed in the output of the show ip route command. R 192.168.3.0/24 [120/3] via 192.168.2.2, 00:00:30, Serial0/0 What is the value of the routing metric? 3 Which of the following is considered a limitation of RIP v1? RIP v1 does not send subnet mask information in its updates. Refer to the exhibit. The Ethernet interface on Router2 goes down and the administrator notices that the route is still in the Router1 routing table. How much longer will Router1 keep the down network in its routing table before marking it as possibly do
