Q31. - (Topic 7)
An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below.
Click the console connected to RouterC and issue the appropriate commands to answer the questions.
What would be the effect of issuing the command ip access-group 114 in to the fa0/0 interface?
A. Attempts to telnet to the router would fail.
B. It would allow all traffic from the 10.4.4.0 network.
C. IP traffic would be passed through the interface but TCP and UDP traffic would not.
D. Routing protocol updates for the 10.4.4.0 network would not be accepted from the fa0/0 interface.
Answer: B
Explanation:
From the output of access-list 114: access-list 114 permit ip 10.4.4.0 0.0.0.255 any we can easily understand that this access list allows all traffic (ip) from 10.4.4.0/24 network
Q32. - (Topic 3)
Refer to the graphic.
A static route to the 10.5.6.0/24 network is to be configured on the HFD router. Which commands will accomplish this? (Choose two.)
A. HFD(config)# ip route 10.5.6.0 0.0.0.255 fa0/0
B. HFD(config)# ip route 10.5.6.0 0.0.0.255 10.5.4.6
C. HFD(config)# ip route 10.5.6.0 255.255.255.0 fa0/0
D. HFD(config)# ip route 10.5.6.0 255.255.255.0 10.5.4.6
E. HFD(config)# ip route 10.5.4.6 0.0.0.255 10.5.6.0
F. HFD(config)# ip route 10.5.4.6 255.255.255.0 10.5.6.0
Answer: C,D
Explanation:
The simple syntax of static route:
ip route destination-network-address subnet-mask {next-hop-IP-address | exit-interface}
+ destination-network-address: destination network address of the remote network
+ subnet mask: subnet mask of the destination network
+ next-hop-IP-address: the IP address of the receiving interface on the next-hop router
+ exit-interface: the local interface of this router where the packets will go out In the statement “ip route 10.5.6.0 255.255.255.0 fa0/0:
+ 10.5.6.0 255.255.255.0: the destination network
+fa0/0: the exit-interface
Q33. - (Topic 4)
It has become necessary to configure an existing serial interface to accept a second Frame Relay virtual circuit. Which of the following procedures are required to accomplish this task? (Choose three.)
A. Remove the IP address from the physical interface.
B. Encapsulate the physical interface with multipoint PPP.
C. Create the virtual interfaces with the interface command.
D. Configure each subinterface with its own IP address.
E. Disable split horizon to prevent routing loops between the subinterface networks.
F. Configure static Frame Relay map entries for each subinterface network.
Answer: A,C,D
Explanation:
For multiple PVC’s on a single interface, you must use subinterfaces, with each subinterface configured for each PVC. Each subinterface will then have its own IP address, and no IP address will be assigned to the main interface.
Q34. - (Topic 8)
What is the default VLAN on an access port?
A. 0
B. 1
C. 10
D. 1024
Answer: B
Q35. - (Topic 7)
Scenario
Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.
The EIGRP routing protocol is configured.
You are required to troubleshoot and resolve the EIGRP issues between the various routers.
Use the appropriate show commands to troubleshoot the issues.
Study the following output taken on R1: R1# Ping 10.5.5.55 source 10.1.1.1 Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds:
Packet sent with a source address of 10.1.1.1
…….
Success rate is 0 percent (0/5) Why are the pings failing?
A. The network statement is missing on R5.
B. The loopback interface is shut down on R5.
C. The network statement is missing on R1.
D. The IP address that is configured on the Lo1 interface on R5 is incorrect.
Answer: C
Explanation:
R5 does not have a route to the 10.1.1.1 network, which is the loopback0 IP address of R1. When looking at the EIGRP configuration on R1, we see that the 10.1.1.1 network statement is missing on R1.
Q36. - (Topic 8)
Which Cisco platform can verify ACLs?
A. Cisco Prime Infrastructure
B. Cisco Wireless LAN Controller
C. Cisco APIC-EM
D. Cisco IOS-XE
Answer: B
Q37. - (Topic 3)
A network administrator needs to allow only one Telnet connection to a router. For anyone viewing the configuration and issuing the show run command, the password for Telnet access should be encrypted. Which set of commands will accomplish this task?
A. service password-encryption
access-list 1 permit 192.168.1.0 0.0.0.255
line vty 0 4 login
password cisco access-class 1
B. enable password secret line vty 0
login
password cisco
C. service password-encryption line vty 1
login
password cisco
D. service password-encryption line vty 0 4
login
password cisco
Answer: C
Explanation:
Only one VTY connection is allowed which is exactly what's requested. Incorrect Answer: command.
line vty0 4
would enable all 5 vty connections.

Q38. - (Topic 5)
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).
Q39. - (Topic 8)
Which component of the Cisco SDN solution serves as the centralized management system?
A. Cisco OpenDaylight
B. Cisco ACI
C. Cisco APIC
D. Cisco IWAN
Answer: B
Explanation:
Cisco ACI is a comprehensive SDN architecture. This policy-based automation solution supports a business-relevant application policy language, greater scalability through a distributed enforcement system, and greater network visibility. These benefits are achieved through the integration of physical and virtual environments under one policy model for networks, servers, storage, services, and security.
Q40. - (Topic 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 “no keepalive” command). This status is rarely seen so it is ignored in some books.
