NO.1 Which technology allows multiple VLANs to be extended across the network without the need for Layer 3 routing? A. access ports B. MPLS tunnels C. IPsec tunnels D. trunk ports Answer: D NO.

3 NO.1 Which technology allows multiple VLANs to be extended across the network without the need for Layer 3 routing? A. access ports B. MPLS tunnels C. IPsec tunnels D. trunk ports Answer: D NO.2 R1 is configured with the default configuration of OSPF. From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID? A B C D Answer: D The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence. + The highest IP address assigned to a loopback (logical) interface. + If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen. + The router ID can be manually assigned In this case, because a loopback interface is not configured so the highest active IP address is chosen as the router ID. NO.3 An administrator previously changed the encapsulation on a synchronous serial line and saved the configuration. Now the administrator wants to restore the encapsulation back to the default.

4 What action can the administrator do to return the interface back to its default encapsulation? A. Issue the shutdown then no shutdown commands to reset the encapsulation on the interface. B. Change the encapsulation to ARP C. Configure the interface for HDLC encapsulation. D. Reboot the router and allow it to reload the configuration. E. Remove the cable and plug it back in to allow the router to autonegotiate encapsulation settings. Answer: C NO.4 Which statement about standard access list is true? A. They can use either a wildcard mask or a subnet mask to identify host B. They must be placed close to the source of traffic C. They have an implicit permit statement at the end to allow all traffic D. They can be identified by a number from 1 to 99 Answer: D NO.5 There are three locations in a school district of a large city: ROUTER -M, ROUTER -W and ROUTER -U. The network connection between two of these locations has already functioned. Configure the ROUTER -M router IP addresses on the E0 and S0 interfaces so that the E0 receives the first usable subnet while the S0 receives the second usable subnet from the network /28. Both interfaces would receive the last available ip address on the proper subnet. Get Latest & Valid Exam's Question and Answers 3 from Examtorrent.com. 3

You have determined that computer A cannot ping computer B. Which reason for the problem is most likely true? A. The computer B subnet mask is incorrect. B. The computer B default gateway address is incorrect.

6 You have determined that computer A cannot ping computer B. Which reason for the problem is most likely true? A. The computer B subnet mask is incorrect. B. The computer B default gateway address is incorrect. C. The computer A default gateway address is incorrect. D. The computer A subnet mask is incorrect. Answer: C NO.9 Which statements describe the routing protocol OSPF? (Choose three.) A. It is simpler to configure than RIP v2. B. It increases routing overhead on the network. C. It is used to route between autonomous systems. D. It confines network instability to one area of the network. E. It supports VLSM. F. It allows extensive control of routing updates. Answer: D,E,F Routing overhead is the amount of information needed to describe the changes in a dynamic network topology. All routers in an OSPF area have identical copies of the topology database and the topology database of one area is hidden from the rest of the areas to reduce routing overhead because fewer routing updates are sent and smaller routing trees are computed and maintained (allow extensive control of routing updates and confine network instability to one area of the network). NO.10 Refer to the exhibit. The network administrator must complete the connection between the RTA of the XYZ Company and the service provider.

CSU/DSU E. modem F. PVC Answer: D,E NO.11 What is true about ipv6 unique local addresses: A. Summarization B. Unique prefix C. Public routable D. Global id Answer: B NO.12 For which reason does an administrator implement static routing? A. to provide quick convergence when links fail on the enterprise network B. to simplify network maintenance in a large enterprise C. to reduce the amount of time required to deploy new devices on the network D. to reduce overhead on a stub router that requires access only to a default route Answer: D NO.13 Which method does a connected trunk port use to tag VLAN traffic? A. IEEE 802 1Q B. IEEE 802 1D C. IEEE 802 1p D. IEEE 802 1w Answer: A IEEE 802.1Q is the networking standard that supports virtual LANs (VLANs) on an Ethernet network. When a frame enters the VLAN-aware portion of the network (a trunk link, for example), a VLAN ID tag is added to represent the VLAN membership of that frame. The picture below shows how VLAN tag is added and removed while going through the network. Get Latest & Valid Exam's Question and Answers 6 from Examtorrent.com. 6

A technician is troubleshooting a host connectivity problem. The host is unable to ping a server connected to Switch_A. Based on the results of the testing, what could be the problem? A. A remote physical layer problem exists. B. TCP/IP has not been correctly installed on the host. C. The host NIC is not functioning. D. A local physical layer problem exists. Answer: D Here we see that the host is able to ping its own loopback IP address of and it's own IP address of , so we know that the NIC is functioning and that the host's TCP/IP stack is OK.

9 However, it is not able to ping the IP address of its local default gateway, so we know that there is a local cabling problem between the switch and the router. NO.16 Which statement about IPv6 link-local addresses is true? A. They must be configured on all IPv6 interface B. They are advertised globally on the network C. They must be globally unique D. They must be manually configured Answer: A NO.17 Which destination IP address can a host use to send one message to multiple devices across different subnets? A B C D Answer: A Multicast is a networking protocol where one host can send a message to a special multicast IP address and one or more network devices can listen for and receive those messages. Multicast works by taking advantage of the existing IPv4 networking infrastructure, and it does so in something of a weird fashion. As you read, keep in mind that things are a little confusing because multicast was "shoe-horned" in to an existing technology. For the rest of this article, let's use the multicast IP address of We'll not worry about port numbers yet, but make a mental note that they are used in multicast. We'll discuss that later.

The junior network support staff provided the diagram as a recommended configuration for the first phase of a four-phase network expansion project.

10 The junior network support staff provided the diagram as a recommended configuration for the first phase of a four-phase network expansion project. The entire network expansion will have over 1000 users on 14 network segments and has been allocated this IP address space through through What are three problems with this design? (Choose three.) A. The network address space that is provided requires a single network-wide mask. B. The router-to-router connection is wasting address space. C. The broadcast domain in AREA 1 is too large for IP to function. D. AREA 2 could use a mask of /25 to conserve IP address space. E. The AREA 1 IP address space is inadequate for the number of users. F. The AREA 3 IP address space is inadequate for the number of users. Answer: B,D,E The given IP addresses of areas 1 and 3 along with network masks of /24 cannot accommodate 500 users so are inadequate, while the area 2 is having over capacity so its network mask can be reduced to /25 to accommodate the only 60 users it has. NO.19 On which type of device is every port in the same collision domain? A. a Layer 2 switch B. a hub C. a router Answer: B Collision domain A collision domain is, as the name implies, a part of a network where packet collisions can occur. A Get Latest & Valid Exam's Question and Answers 9 from Examtorrent.com. 9

11 collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.
