Question No: 4

The output of the show frame-relay pvc command shows "PVC STATUS = INACTIVE". What does this mean?

A. The PVC is configured correctly and is operating normally, but no data packets have been detected for more than five minutes.

B. The PVC is configured correctly, is operating normally, and is no longer actively seeking the address of the remote router.

C. The PVC is configured correctly, is operating normally, and is waiting for interesting traffic to trigger a call to the remote router.

D. The PVC is configured correctly on the local switch, but there is a problem on the remote end of the PVC.

E. The PVC is not configured on the local switch.

Answer: D

Explanation:

The PVC STATUS displays the status of the PVC. The DCE device creates and sends the report to the DTE devices. There are 4 statuses:

+ ACTIVE: the PVC is operational and can transmit data

+ INACTIVE: the connection from the local router to the switch is working, but the connection to the remote router is not available

+ DELETED: the PVC is not present and no LMI information is being received from the Frame Relay switch

+ STATIC: the Local Management Interface (LMI) mechanism on the interface is disabled (by using the u201cno keepaliveu201d command). This status is rarely seen so it is ignored in some books.

Question No: 5

Which two benefits are provided by creating VLANs? (Choose two.)

A. added security

B. dedicated bandwidth

C. provides segmentation

D. allows switches to route traffic between subinterfaces

E. contains collisions

Answer: A,C

Explanation:

AVLAN is a switched network that is logically segmented on an organizational basis, by

functions, project teams, or applications rather than on a physical or geographical basis. Security:

VLANs also improve security by isolating groups. High-security users can be grouped into a VLAN, possible on the same physical segment, and no users outside that VLAN can communicate with them.

LAN Segmentation

VLANs allow logical network topologies to overlay the physical switched infrastructure such that any arbitrary collection of LAN ports can be combined into an autonomous user group or community of interest. The technology logically segments the network into separate Layer 2 broadcast domains whereby packets are switched between ports designated to be within the same VLAN. By containing traffic originating on a particular LAN only to other LANs in the same VLAN, switched virtual networks avoid wasting bandwidth.

Question No: 6

Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 to OSPF area 0? (Choose two.)

A. Router(config)# router ospf 0

B. Router(config)# router ospf 1

C. Router(config)# router ospf area 0

D. Router(config-router)# network 192.168.16.0 0.0.0.255 0

E. Router(config-router)# network 192.168.16.0 0.0.0.255 area 0

F. Router(config-router)# network 192.168.16.0 255.255.255.0 area 0

Answer: B,E

Explanation:

In the router ospf command, the ranges from 1 to 65535 so o is an invalid number -> but To configure OSPF, we need a wildcard in the u201cnetworku201d statement, not a subnet mask. We also need to assgin an area to this process ->.

Question No: 7

Which command shows your active Telnet connections?

A. show cdp neigbors

B. show session

C. show users

D. show vty logins

Answer: B

Explanation:

The u201cshow usersu201d shows telnet/ssh connections to your router while u201cshow sessionsu201d shows telnet/ssh connections from your router (to other devices). The question asks about u201cyour active Telnet connectionsu201d, meaning connections from your router so the answer should be A.

Question No: 8

Refer to the exhibit.

A technician is troubleshooting host connectivity issues on the switches. The hosts in VLANs 10 and 15 on Sw11 are unable to communicate with hosts in the same VLANs on Sw12. Hosts in the Admin VLAN are able to communicate. The port-to-VLAN assignments are identical on the two switches. What could be the problem?

A. The Fa0/1 port is not operational on one of the switches.

B. The link connecting the switches has not been configured as a trunk.

C. At least one port needs to be configured in VLAN 1 for VLANs 10 and 15 to be able to communicate.

D. Port FastEthernet 0/1 needs to be configured as an access link on both switches.

E. A router is required for hosts on SW11 in VLANs 10 and 15 to communicate with hosts in the same VLAN on Sw12.

Answer: B

Explanation:

In order for hosts in the same VLAN to communicate with each other over multiple switches, those switches need to be configured as trunks on their connected interfaces so that they can pass traffic from multiple VLANs.

Question No: 9

The network administrator cannot connect to Switch1 over a Telnet session, although the hosts attached to Switch1 can ping the interface Fa0/0 of the router.

Given the information in the graphic and assuming that the router and Switch2 are configured properly, which of the following commands should be issued on Switch1 to correct this problem?

A. Switch1(config)# line con0 Switch1(config-line)# password cisco Switch1(config-line)#login

B. Switch1(config)# interface fa0/1

Switch1(config-if)# ip address 192.168.24.3 255.255.255.0

C. Switch1(config)# ip default-gateway 192.168.24.1

D. Switch1(config)# interface fa0/1 Switch1(config-if)# duplex full

Switch1(config-if)# speed 100

E. Switch1(config)# interface fa0/1 Switch1(config-if)# switchport mode trunk

Answer: C

Explanation:

Since we know hosts can reach the router through the switch, we know that connectivity, duplex. Speed, etc. are good. However, for the switch itself to reach networks outside the local one, the ip default-gateway command must be used.

Question No: 10

Which three statements about HSRP operation are true? (Choose three.)

A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.

B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.

C. HSRP supports only clear-text authentication.

D. The HSRP virtual IP address must be on a different subnet than the routers' interfaces on the same LAN.

E. The HSRP virtual IP address must be the same as one of the router's interface addresses on the LAN.

F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.

Answer: A,B,F

Explanation:

The virtual MAC address of HSRP version 1 is 0000.0C07.ACxx, where xx is the HSRP

group number in hexadecimal based on the respective interface. For example, HSRP group 10 uses the HSRP virtual MAC address of 0000.0C07.AC0A. HSRP version 2 uses a virtual MAC address of 0000.0C9F.FXXX (XXX: HSRP group in hexadecimal).

Question No: 11

What will happen if a private IP address is assigned to a public interface connected to an ISP?

A. Addresses in a private range will not be routed on the Internet backbone.

B. Only the ISP router will have the capability to access the public network.

C. The NAT process will be used to translate this address to a valid IP address.

D. A conflict of IP addresses happens, because other public routers can use the same range.

Answer: A

Explanation:

Private RFC 1918 IP addresses are meant to be used by organizations locally within their own network only, and cannot be used globally for Internet use.

Question No: 12

Refer to the exhibit.

A technician has installed SwitchB and needs to configure it for remote access from the management workstation connected to SwitchA. Which set of commands is required to accomplish this task?

A. SwitchB(config)# interface FastEthernet 0/1 SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

B. SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0

SwitchB(config-if)# ip default-gateway 192.168.8.254 255.255.255.0 SwitchB(config-if)# no shutdown

C. SwitchB(config)# ip default-gateway 192.168.8.254 SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

D. SwitchB(config)# ip default-network 192.168.8.254 SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

E. SwitchB(config)# ip route 192.168.8.254 255.255.255.0 SwitchB(config)# interface FastEthernet 0/1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

Answer: C

Explanation:

To remote access to SwitchB, it must have a management IP address on a VLAN on that

switch. Traditionally, we often use VLAN 1 as the management VLAN (but in fact it is not secure).

In the exhibit, we can recognize that the Management Workstation is in a different subnet from the SwitchB. For intersubnetwork communication to occur, you must configure at least one default gateway. This default gateway is used to forward traffic originating from the switch only, not to forward traffic sent by devices connected to the switch.

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?

A. 10.1.1.2

B. 10.154.154.1

C. 172.16.5.1

D. 192.168.5.3

Answer: C

Explanation:

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