New Questions 1

Which two statements about static NAT translations are true? (Choose two.)

A. They allow connections to be initiated from the outside.

B. They require no inside or outside interface markings because addresses are statically defined.

C. They are always present in the NAT table.

D. They can be configured with access lists, to allow two or more connections to be initiated from the outside.

Answer: A,C

Explanation:

Static NAT is to map a single outside IP address to a single inside IP address. This is typically done to allow incoming connections from the outside (Internet) to the inside. Since these are static, they are always present in the NAT table even if they are not actively in use.

New Questions 2

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.

New Questions 3

Refer to the exhibit.

All switch ports are assigned to the correct VLANs, but none of the hosts connected to SwitchA can communicate with hosts in the same VLAN connected to SwitchB. Based on the output shown, what is the most likely problem?

A. The access link needs to be configured in multiple VLANs.

B. The link between the switches is configured in the wrong VLAN.

C. The link between the switches needs to be configured as a trunk.

D. VTP is not configured to carry VLAN information between the switches.

E. Switch IP addresses must be configured in order for traffic to be forwarded between the switches.

Answer: C

Explanation:

In order to pass traffic from VLANs on different switches, the connections between the switches must be configured as trunk ports.

New Questions 4

Two routers named Atlanta and Brevard are connected via their serial interfaces as illustrated, but they are unable to communicate. The Atlanta router is known to have the correct configuration.

Given the partial configurations, identify the fault on the Brevard router that is causing the lack of connectivity.

A. incompatible IP address

B. insufficient bandwidth

C. incorrect subnet mask

D. incompatible encapsulation

E. link reliability too low

F. IPCP closed

Answer: D

Explanation:

Because Interface Serial 0 of Atlanta Router has 192.168.10.1 And Interface Serial 1 of Router Brevard has 192.168.11.2. These are from different network.

New Questions 5

Which command allows you to verify the encapsulation type (CISCO or IETF) for a Frame Relay link?

A. show frame-relay lmi

B. show frame-relay map

C. show frame-relay pvc

D. show interfaces serial

Answer: B

Explanation:

When connecting Cisco devices with non-Cisco devices, you must use IETF4 encapsulation on both devices. Check the encapsulation type on the Cisco device with the show frame-relay mapexec command.

New Questions 6

Assuming the default switch configuration, which VLAN range can be added, modified, and removed on a Cisco switch?

A. 1 through 1001

B. 2 through 1001

C. 1 through 1002

D. 2 through 1005

Answer: B

Explanation: Explanation

VLAN 1 is the default VLAN on Cisco switch. It always exists and cannot be added, modified or removed.

VLANs 1002-1005 are default VLANs for FDDI & Token Ring and they canu2021t be deleted or used for Ethernet.

New Questions 7

Refer to the exhibit.

According to the routing table, where will the router send a packet destined for 10.1.5.65?

A. 10.1.1.2

B. 10.1.2.2

C. 10.1.3.3

D. 10.1.4.4

Answer: C

Explanation:

The destination IP address 10.1.5.65 belongs to 10.1.5.64/28, 10.1.5.64/29 & 10.1.5.64/27 subnets but the u201clongest prefix matchu201d algorithm will choose the most specific subnet mask

-> the prefix u201c/29 will be chosen to route the packet. Therefore the next-hop should be

10.1.3.3 ->.

Topic 8, WAN Technologies

739.A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection?

A. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.252 Main(config-if)# no shut

B. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.252 Main(config-if)# encapsulation ppp

Main(config-if)# no shut

C. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.252 Main(config-if)# encapsulation frame-relay

Main(config-if)# authentication chap Main(config-if)# no shut

D. Main(config)# interface serial 0/0

Main(config-if)#ip address 172.16.1.1 255.255.255.252 Main(config-if)#encapsulation ietf

Main(config-if)# no shut

Answer: B

Explanation:

With serial point to point links there are two options for the encapsulation. The default, HDLC, is Cisco proprietary and works only with other Cisco routers. The other option is PPP which is standards based and supported by all vendors.

New Questions 8

Which two are advantages of static routing when compared to dynamic routing? (Choose two.)

A. Configuration complexity decreases as network size increases.

B. Security increases because only the network administrator may change the routing table.

C. Route summarization is computed automatically by the router.

D. Routing tables adapt automatically to topology changes.

E. An efficient algorithm is used to build routing tables, using automatic updates.

F. Routing updates are automatically sent to neighbors.

G. Routing traffic load is reduced when used in stub network links.

Answer: B,G

Explanation:

Since static routing is a manual process, it can be argued that it is more secure (and more prone to human errors) since the network administrator will need to make changes to the routing table directly. Also, in stub networks where there is only a single uplink connection, the load is reduced as stub routers just need a single static default route, instead of many routes that all have the same next hop IP address.

New Questions 9

A network administrator enters the following command on a router: logging trap 3. What are three message types that will be sent to the Syslog server? (Choose three.)

A. informational

B. emergency

C. warning

D. critical

E. debug

F. error

Answer: B,D,F

Explanation:

The Message Logging is divided into 8 levels as listed below:

Level Keyword Description 0

emergencies System is unusable 1

alerts

Immediate action is needed 2

critical

Critical conditions exist 3

errors

Error conditions exist

4

warnings

Warning conditions exist 5

notification

Normal, but significant, conditions exist 6

informational Informational messages 7

debugging Debugging messages

If you specify a level with the u201cloggingtrap levelu201d command, that level and all the higher levels will be logged. For example, by using the u201clogging trap 3 command, all the logging of emergencies, alerts, critical, and errors, will be logged.

New Questions 10

Refer to the exhibit.

Which switch provides the spanning-tree designated port role for the network segment that services the printers?

A. Switch1

B. Switch2

C. Switch3

D. Switch4

Answer: C

Explanation:

Printers are connected by hubs. Decide the switch that provides the spanning-tree designated port role between Switch3 and Switch4. They have the same priority 32768. Compare their MAC addresses. Switch3 with a smaller MAC address will provide a designated port for printers.
