QUESTION 311

Before inserting a new switch in the network, the network administrator checks that the VTP domain name is correct, the VTP mode is set to server, and revision is lower than the switches in the network. The administrator then configures interfaces and trunks, erases existing VLANs, and connects the switch to the network. Following that procedure, there is no connectivity in the network. What is a possible cause of this problem?

 

A.       Because the configuration revision of the new switches is lower than the rest of the network, it can change the VLAN database of the other switches.

B.       As a VTP server, the new switch deleted all VLANs of the network.

C.       Erasing VLANs increases the VTP configuration revision.

D.       Since the configuration revision of the network is higher than the new switch, the VLAN database was automatically synchronized.

 

Correct Answer: C

 

 

QUESTION 312

The network administrator wants to enable an EtherChannel between two switches in “on” mode. The administrator connects the cables and enables the interfaces, but while configuring the EtherChannel in the first switch, a spanning-tree loop was detected. Which two of these procedures can avoid this problem? (Choose two.)

 

A.       Configure the EtherChannel as “desirable” first.

B.       Assign all interfaces to the same VLAN.

C.       Disable PortFast on the interfaces in the EtherChannels.

D.      Disable all interfaces first.

E.       Fast Ethernet and Gigabit Ethernet ports cannot be assigned to the same EtherChannel.

F.        Fix cabling problems.

 

Correct Answer: AD

 

 

QUESTION 313

Customer X has a hub-and-spoke Frame Relay network, with a central office and two branch offices (RemoteA and RemoteB). Each location has only one physical link to the Frame Relay cloud and RemoteB has a router that is not a Cisco router. Since the installation, there is no connectivity between RemoteB and the central office. What is a possible solution to this issue?

 

A.       Because Frame Relay IETF encapsulation is only configurable at interface level, you must use IETF encapsulation on all routers.

B.       This is not a possible scenario. A dedicated Frame Relay link to RemoteB is mandatory at the central office.

C.       The router at RemoteB must be replaced by a Cisco router.

D.       Use Frame Relay IETF encapsulation on a per-VC basis on the central office router.

E.        There is a problem in the Frame Relay cloud, because Cisco routers are compatible with IETF Frame Relay.

 

Correct Answer: D

 

 

QUESTION 314

You are deploying two core switches, one in each building, 50 km away from each other. The cross- connection between them will be a Layer 2 2-gigabit EtherChannel with an 802.1Q trunk. You configured it correctly but the link does not come up. The port is in the “admin up” state, and the line protocol is in the “down” state. The fiber link is OK. What would be the most likely reason for the link not to come up?

 

A.       The switches are not the same model.

B.       You are not using the correct SFP.

C.       You are not using correct optical media converters.

D.      Configuration should be modified, because the distance is longer.

 

Correct Answer: B

 

 

QUESTION 315

You are configuring an 802.1Q trunk between a Layer 2 switch and a firewall. You read in the documentation that the best way to set up a trunk is to set the port as dynamic desirable. The trunk is not coming up. Which one of these options would be a valid explanation?

 

A.       The firewall does not support Cisco Discovery Protocol. You should set the switchport trunk mode ON.

B.       The firewall does not support Cisco Discovery Protocol. You should set the switchport trunk mode to OFF.

C.       The firewall does not support Cisco Discovery Protocol. You should set the switchport trunk mode as auto.

D.       The firewall does not support DTP. You should set the switchport trunk mode to ON.

 

Correct Answer: D

 

 

QUESTION 316

Refer to the exhibit. You are setting up a 2-gigabit EtherChannel. Following IEEE standards, the exhibit shows your configuration in a local switchl. However, EtherChannel is not coming up. Which one of these statements could be a possible reason?

 

clip_image001

 

A.       EtherChannel is only available in Cisco equipment.

B.       The customer side is supposed to be running PAgP, which is a Cisco standard.

C.       PAgP is not an IEEE standard. VRRP should be used.

D.      The configuration on switch1 needs to be modified to use LACP.

 

Correct Answer: D

 

 

QUESTION 317

Refer to the exhibit. R2 and R3 are routers connected using Ethernet services from a service provider and can receive pings from each other. OSPF is configured as the routing protocol but adjacency is not happening. According to the output of the show commands in the exhibit, what could be the most likely cause of the problem?

clip_image003

A.       Ethernet interfaces were configured as point-to-point.

B.       Process IDs are not matching.

C.       Configured bandwidths do not match on both interfaces.

D.      Broadcasts and multicast are not being propagated over the Ethernet services.

E.       OSPF cost does not match on both interfaces.

 

Correct Answer: D

 

 

QUESTION 318

Which mechanism can you use to achieve sub-second failover for link failure detection when a switched Ethernet media is used and loss of signal is not supported by the link provider?

 

A.       OSPF standard hellos

B.       Cisco Discovery Protocol link detection

C.       Bidirectional Forwarding Detection

D.      Fast Link Pulse

E.       autonegotiation

 

Correct Answer: C

 

 

QUESTION 319

While troubleshooting a network, you need to verify the liveness of hosts in the subnet 192.168.1.64/26. All of the hosts are able to reply to ping requests. How would you confirm the existing nodes using one single command?

 

A.       ping 192.168.1.255

B.       ping with sweep option

C.       ping 192.168.1.127

D.      ping 192.168.1.64

E.       P>ng with broadcast option

 

Correct Answer: C

 

 

QUESTION 320

Refer to the exhibit. There are two sites connected ac
ross WAN links. All intersite and intrasite links always have the same routing metric. The network administrator sees only the top routers and links being used by hosts at both LAN A and LAN B. What would be two suggestions to load- balance the traffic across both WAN links? (Choose two.)

clip_image004

 

A.       Make HSRP track interfaces between the edge and core routers.

B.       Replace HSRP with GLBP.

C.       Add crossed intrasite links: R1-R4, R2-R3, R5-R8, and R6-R7.

D.      Make R3 and R8 have lower HSRP priority than R1 and R7.

E.       Replace HSRP with VRRP.

 

Correct Answer: BC
