A network technician analyzes the network and notices late collisions. The collisions occur accompanied by jabber that originates from the server. What is the likely cause of the problem?

Refer to the exhibit. This router is being configured to use SDM, but the SDM interface of the router cannot be accessed. What is the cause of the problem?

Which configuration on the vty lines provides the best security measure for network administrators to remotely access the core routers at headquarters?

Refer to the exhibit. What can be concluded from the exhibited output of the debug ip nat command?

Refer to the exhibit. A network administrator is creating a prototype to verify the new WAN design. However, the communication between the two routers cannot be established. Based on the output of the commands, what can be done to solve the problem?

A technician has been asked to run the Cisco SDM one-step lockdown on a customer router. What will be the result of this process?

Which Frame Relay flow control mechanism is used to signal routers that they should reduce the flow rate of frames?

An administrator learns of an e-mail that has been received by a number of users in the company. This e-mail appears to come from the office of the administrator. The e-mail asks the users to confirm their account and password information. Which type of security threat does this e-mail represent?

Refer to the exhibit. A network administrator configures a standard access control list on Router1 to prohibit traffic from the 192.168.0.0/24 network from reaching the Internet. The access control list also permits traffic from the 192.168.0.0/24 network to reach the 192.168.1.0/24 network. On which interface and in which direction should the access control list be applied?

An administrator issues the command show interfaces s0/1/0 on a router that is configured for Frame Relay. Which console output may indicate an LMI mismatch?

What is the result of adding the global command service password-encryption to the configuration of a router?

Refer to the exhibit. This router is being configured to use SDM, but the SDM interface of the router cannot be accessed. What is the cause of the problem?

A recently patched application server is experiencing response time problems. The network on which the application server is located has been experiencing occasional outages that the network team believes may be related to recent routing changes. Network and application teams have been notified to work on their respective issues. Which statement applies to this situation?

What does an access control list determine when used with NAT on a Cisco router?

Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP request that enters interface s0/0/0 and is destined for an FTP server at IP address 192.168.1.5?

When Frame Relay encapsulation is used, what feature provides flow control and exchanges information about the status of virtual circuits?

Refer to the exhibit. From the output of the show interfaces and ping commands, at which layer of the OSI model is a fault indicated?

Refer to the exhibit. EIGRP has been configured as a routing protocol on the network. Users on the 192.168.1.0/24 network should have full access to the web server that is connected to 192.168.3.0/24 but should not be allowed to telnet to router R3. Verifying the configuration, the network administrator realizes that users on network 192.168.1.0/24 can successfully telnet to the router. What should be done to remedy the problem?

What are three important reasons to establish a network baseline? (Choose three.)

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?

Refer to the exhibit. An ACL called Managers already exists on this router. What happens if the network administrator issues the commands as shown in the exhibit?

Which WAN connection type uses a fixed-length 53 byte cell for transmitting data?

What three questions can be answered using data gathered from a baseline on a new network? (Choose three.)

Refer to the exhibit. An ACL called Managers already exists on this router. What happens if the network administrator issues the commands as shown in the exhibit?

Which two statements are true about creating and applying access lists? (Choose two.)

Which IP address and wildcard mask would be used in an ACL to block traffic from all hosts on the same subnet as host 192.168.16.43/28?

Refer to the exhibit. A network administrator is tasked with completing the Frame Relay topology that interconnects two remote sites. How should the point-to-point subinterfaces be configured on HQ to complete the topology?
