Q81. - (Topic 5)
What command instructs the device to timestamp Syslog debug messages in milliseconds?
A. service timestamps log datetime localtime<input type
B. service timestamps debug datetime msec<input type
C. service timestamps debug datetime localtime<input type
D. service timestamps log datetime msec
Answer: B
Explanation:
Enable millisecond (msec) timestamps using the service timestamps command: router(config)#service timestamps debug datetime msec.
router(config)#service timestamps log datetime msec The “service timestamps debug”. command configures the system to apply a time stamp to debugging messages. The time- stamp format for datetime is MMM DD HH:MM:SS, where MMM is the month, DD is the date, HH is the hour (in 24-hour notation), MM is the minute, and SS is the second. With the additional keyword msec, the system includes milliseconds in the time stamp, in the format HH:DD:MM:SS.mmm, where .mmm is milliseconds.
Q82. - (Topic 8)
Which action can change the order of entries in a named access list?
A. opening the access list in Notepad.
B. resequercing
C. removing an entry
D. adding an entry
Answer: B
Q83. - (Topic 5)
Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two.)
A. Set the IP gateway to be used by the network.
B. Perform host discovery used DHCPDISCOVER message.
C. Configure IP address parameters from DHCP server to a host.
D. Provide an easy management of layer 3 devices.
E. Monitor IP performance using the DHCP server.
F. Assign and renew IP address from the default pool.
Answer: C,F
Explanation:
The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model. DHCP servers assigns IP addresses from a pool of addresses and also assigns other parameters such as DNS and default gateways to hosts.
Q84. - (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
Q85. - (Topic 3)
What OSPF command, when configured, will include all interfaces into area 0?
A. network 0.0.0.0 255.255.255.255 area 0
B. network 0.0.0.0 0.0.0.0 area 0
C. network 255.255.255.255 0.0.0.0 area 0
D. network all-interfaces area 0
Answer: A
Explanation:
Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0. The network command network 0.0.0.0 255.255.255.255 area 0 dictates that you do not care (255.255.255.255) what the IP address is, but if an IP address is enabled on any interface, place it in area 0.
Example 3-1 Configuring OSPF in a Single Area
router ospf 1
network 0.0.0.0 255.255.255.255 area 0

Q86. - (Topic 8)
Which configuration can you apply to enable encapsulation on a subinterface?
A. interface FastEthernet 0/0 encapsulation dot1Q 30
ip address 10.1.1.30 255.255.255.0
B. interface FastEthernet 0/0.30
ip address 10.1.1.30 255.255.255.0
C. interface FastEthernet 0/0.30 description subinterface vlan 30
D. interface FastEthernet 0/0.30 encapsulation dot1Q 30
ip address 10.1.1.30 255.255.255.0
Answer: D
Q87. - (Topic 3)
Refer to the exhibit.
The network administrator requires easy configuration options and minimal routing protocol traffic. What two options provide adequate routing table information for traffic that passes between the two routers and satisfy the requests of the network administrator? (Choose two.)
A. a dynamic routing protocol on InternetRouter to advertise all routes to CentralRouter.
B. a dynamic routing protocol on InternetRouter to advertise summarized routes to CentralRouter.
C. a static route on InternetRouter to direct traffic that is destined for 172.16.0.0/16 to CentralRouter.
D. a dynamic routing protocol on CentralRouter to advertise all routes to InternetRouter.
E. a dynamic routing protocol on CentralRouter to advertise summarized routes to InternetRouter.
F. a static, default route on CentralRouter that directs traffic to InternetRouter.
Answer: C,F
Explanation:
The use of static routes will provide the necessary information for connectivity while producing no routing traffic overhead.
Q88. - (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.
Q89. - (Topic 8)
If a router has four interfaces and each interface is connected to four switches, how many broadcast domains are present on the router?
A. 1
B. 2
C. 4
D. 8
Answer: C
Q90. - (Topic 4)
Which Layer 2 protocol encapsulation type supports synchronous and asynchronous circuits and has built-in security mechanisms?
A. HDLC
B. PPP
C. X.25
D. Frame Relay
Answer: B
Explanation:
PPP: Provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. PPP was designed to work with several network layer protocols, including IP. PPP also has built-in security mechanisms, such as Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP).
