Which of the following commands should you use to upgrade the IOS stored in flash from an image stored on a TFTP server?

  1. upgrade flash tftp

  2. copy tftp flash

  3. copy flash tftp

  4. copy ios flash


Correct Option: B
Explanation:

copy tftp flash is the correct answer. copy flash tftp creates a backup from the current IOS and stores it in a file on a tftp server.

  1. Routing table

  2. Neighbour table

  3. Topology table

  4. Adjacency table


Correct Option: C

What is a routing loop?

  1. A packet bouncing back and forth between two loopback interfaces on a route.

  2. A condition where a return path from a destination is different from the outbound path forming a loop.

  3. A condition where a packet is constantly transmitted within a series of routers without ever reaching its intended destination.

  4. The distribution of routes from one routing protocol into another.


Correct Option: C

Interface s0/0/0 already has an IP ACL applied inbound. What happens when the network administrator attempts to apply a second inbound IP ACL?

  1. Both ACLs are applied to the interface.

  2. The second ACL is applied to the interface, replacing the first.

  3. The network administrator receives an error.

  4. Only the first ACL remains applied to the interface.


Correct Option: B

Refer to the exhibit. The exhibited network contains a mixture of Cisco and non-Cisco routers. The command debug ip rip was entered on the JAX router. All routers are running the same version of RIP. Router CHI and Router ORL are not able to reach the 192.168.1.16/28 network. What is a possible solution to this problem?

  1. Enable split horizon in the network.

  2. Configure RIPv2 on routers.

  3. Add network 192.168.1.0 to the RIP configuration on the JAX router.

  4. Configure JAX Fa0/0 as a passive interface.

  5. Enable the Serial0/0/0 interface on the JAX router.


Correct Option: A

Refer to the exhibit. Security Device Manager (SDM) is installed on router R1. What is the result of opening a web browser on PC1 and entering the URL https://192.168.10.1?

  1. The password is sent in plain text.

  2. A Telnet session is established with R1.

  3. The SDM page of R1 appears with a dialog box that requests a username and password.

  4. The R1 home page is displayed and allows the user to download Cisco IOS images and configuration files.


Correct Option: C

When connectionless protocols are implemented at the lower layers of the OSI model, what is usually used to acknowledge that the data was received and to request the retransmission of missing data?

  1. IP

  2. UDP

  3. Ethernet

  4. A connectionless acknowledgement

  5. An upper-layer, connection-oriented protocol or service


Correct Option: D

Refer to the exhibit. All routers are running RIP version 2. JAX is configured to just advertise the 10.0.0.0/24 network. CHI is configured to advertise the 172.16.0.0/16 network. A network administrator enters the commands shown in the exhibit. What changes will occur in this network?

  1. The JAX router will ignore updates for the 172.16.0.0/16 network due to split horizon issues.

  2. The CHI router will install a route to the 192.168.0.0/16 network in its routing table.

  3. The routing table for CHI will have the 192.168.0.0/16 route but it will have an S next to the route.

  4. The ORL router will apply a 255.255.0.0 subnet mask to all networks in the routing updates it forwards.


Correct Option: B

When would the IOS image held in ROM be used to boot the router?

What is the outcome of entering these commands? R1(config)# line vty 0 4 R1(config-line)# password check123 R1(config-line)# login

  1. Ensures that a password is entered before entering user EXEC mode

  2. Sets the password to be used for connecting to this router via Telnet

  3. Requires check123 to be entered before the configuration can be saved

  4. Creates a local user account for logging in to a router or switch

Correct Option: A

What will be the result of adding the command ip dhcp excluded-address 192.168.24.1 192.168.24.5 to the configuration of a local router that has been configured as a DHCP server?

  1. Traffic that is destined for 192.168.24.1 and 192.168.24.5 will be dropped by the router.

  2. Traffic will not be routed from clients with addresses between 192.168.24.1 and 192.168.24.5.

  3. The DHCP server will not issue the addresses ranging from 192.168.24.1 to 192.168.24.5.

  4. The router will ignore all traffic that comes from the DHCP servers with addresses 192.168.24.1 and 192.168.24.5.
