You've backed up the router config to a remote location in an encrypted file. You access the router config interface from your notebook computer using an SSH client with the user name *admin01* and the password *P@ssW0rd*. You have used the MD5 hashing algorithm to protect the password. What should you do to increase the security of this device?

Use a web browser to access the router config using an HTTP connection Use an SSH client to access the router configuration Move the device to a secure data center >>Use a stronger admin password

>>Use SCP to back up the router config to a remote location Move the router to a secure data center. Use an SSH client to access the router config Use encrypted type 7 passwords

You've just deployed a new Cisco router that connects several network segments in your organization. The router is physically located in a locked server closet. You use an FTP client to regularly back up the router configuration to a remote sever in an encrypted file. You access the router configuration interface from a notebook computer that is connected to the router's console port. You've configured the device with the user name *admin01* and the password *P@ssW0rd*. You have used the MD5 hashing algorithm to protect the password. What should you do to increase the security of this device?

You've just deployed a new Cisco router that connects several network segments in your organization. The router is physically located in a server room that requires an ID card to gain access. You've backed up the router configuration to a remote location location in an encrypted file. You access the router configuration interface from your notebook computer by connecting it to the console port on the router. You configured the management interface with a user name of admin and a password of password. What should you do to increase the security of this device?

Use Kerberos Use IPsec and certificates >>Use SSL Add SASL and use TLS

Your LDAP directory services solution uses simple authentication. What should you always do when using simple authentication?

Spanning tree VPN >>VLAN Port Security

Your company is a small start-up company that has leased office space in the building shared by other businesses. All businesses share a common infrastructure. A single switch connects all devices in the building to the router that provides internet access. You would like to make sure your computers are isolated from computers used by other companies. What feature should you request to have implemented?

Network firewalling Virtual local area networking >>Network segmentation Trust zone networking

Your network devices are categorized into the following zone types: No-trust zone Low-trust zone Medium-trust zone High-trust zone Your network architecture employs multiple VLANs for each of these network zones. Each zone is separated by a firewall that ensures only specific traffic is allowed. Which of the following is the secure architecture concept that is being used on this network?

>>User education and training Identifying a network baseline Network segmentation Identifying inherent vulnerabilities Documenting all network assets in your organization

Your organization has started receiving phishing emails. You suspect that an attacker is attempting to find an employee workstation they can compromise. You know that a workstation can be used as a pivot point to gain access to more sensitive systems. Which of the following is the most important aspect of maintaining network security against this type of attack?

Implement a packet-filtering firewall in front of the web server Implement an application-aware IDS in front of the web server Install an anti-malware scanner on the web server >>Implement an application-aware IPS in front of the web server Implement a stateful firewall in front of the web server

Your organization uses a web server to host an e-commerce site. Because this web server handles financial transactions, you are concerned that it could become a prime target for exploits. You want to implement a network security control that will analyze the contents of each packet going to or from the web server. The security control must be able to identify malicious payloads and block them.

Determine that the accused employee is innocent and being framed. >>Implement an application control solution Block all outbound ports in the perimeter firewall Call human resources and have the employee fired for violation of the security policy.

Your organization's security policy specifies that peer-to-peer file sharing is not allowed. Recently, you received an anonymous tip that an employee has been using a BitTorrent client to download copyrighted media while at work. You research BitTorrent and find that it uses TCP ports 6881-6889 by default. When you check your perimeter firewall configuration, ports 80 and 443 are open. When you check your firewall logs, you find that no network traffic is using ports 6881-6889 has been blocked. What should you do?
