  Which of the following monitoring devices are used only to recognize suspicious traffic from specific software?

  A. Signature based IPS
  B. Application based IDS
  C. Anomaly based IDS
  D. Application based IPS
  B. Application based IDS

  ---

  Explanation Explanation/Reference:An APIDS monitors the dynamic behavior and state of the protocol and will typically consist of a system or agent that would typically sit between a process, or group of servers, monitoring and analyzing the application protocol between two connected devices.

• Question 402:

  A username provides which of the following?

  A. Biometrics
  B. Identification
  C. Authorization
  D. Authentication
  B. Identification

• Question 403:

  Which of the following performs authentication and provides a secure connection by using 3DES to encrypt all information between two systems?

  A. HTTPS
  B. SSH
  C. RSA
  D. SSL
  B. SSH

  ---

  Explanation Explanation/Reference:DES encryption algorithm encrypts data three times. Three 64-bit keys are used, instead of one, for an overall key length of 192 bits (the first encryption is encrypted with second key, and the resulting cipher text is again encrypted with a third key).

• Question 404:

  Which of the following is the common port used for IMAP?

  A. 25
  B. 53
  C. 143
  D. 443
  C. 143

  ---

  Explanation Explanation/Reference:The Internet Message Access Protocol (commonly known as IMAP) is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. The current version, IMAP version 4 revision 1 (IMAP4rev1), is defined by RFC 3501. An IMAP server typically listens on well-known port 143

• Question 405:

  Which of the following correctly lists the layers of the OSI model starting at Layer 1?

  A. Data Link, Physical, Network, Transport, Presentation, Session, Application.
  B. Physical, Data Link, Network, Transport, Presentation, Session, Application.
  C. Physical, Data Link, Transport, Network, Session, Presentation, Application.
  D. Physical, Data Link, Network, Transport, Session, Presentation, Application.
  D. Physical, Data Link, Network, Transport, Session, Presentation, Application.

• Question 406:

  A network administrator suspects that recent traffic problems could be caused by a high CPU load on company routers. Which of the following would BEST be used to monitor CPU cycles on the routers?

  A. TACACS+
  B. SNMP
  C. Syslog
  D. DOCSIS
  B. SNMP

  ---

  Explanation Explanation/Reference:SNMP, which is widely used in local area networks (LANs), lets you monitor network nodes from a management host. You can monitor network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS).

• Question 407:

  A technician has received several reports from users about slow Internet speeds. The technician can ping the router with 2ms response times and an outside website with 450ms response times. Which of the following is the NEXT step the technician should take?

  A. Check the router WAN interface for input errors.
  B. Check the DNS server.
  C. Verify the local switch is operating properly.
  D. Verify ICMP is permitted through the firewall.
  B. Check the DNS server.

• Question 408:

  A technician troubleshooting an area that is having difficulty connecting to a WAP. After identifying the symptoms, which of the following should the technician do NEXT?

  A. Document findings.
  B. Resolve the issue.
  C. Establish the probable cause.
  D. Implement a solution.
  C. Establish the probable cause.

• Question 409:

  A network administrator must ensure that both the server and the client are authenticated to the wireless system before access is granted. Which of the following should be implemented to meet this requirement?

  A. EAP-PEAP
  B. MAC ACL
  C. EAP-TTLS
  D. MS-CHAPv2
  C. EAP-TTLS

  ---

  Explanation Explanation/Reference:Extensible Authentication Protocol, or EAP, is an authentication framework frequently used in wireless networks and Point-to-Point connections. EAP is an authentication framework providing for the transport and usage of keying material and parameters generated by EAP methods.

• Question 410:

  A network engineer is dispatched to an employee office to troubleshoot an issue with the employee's laptop. The employee is unable to connect to local and remote resources. The network engineer flips the laptop's wireless switch on to resolve the issue. At which of the following layers of the OSI model was the issue resolved?

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 4
  E. Layer 7
  A. Layer 1

  ---

  The bottom layer of the OSI reference model is Layer 1, the physical layer. Thephysical layer is the layer that defines the hardware elements of a network. These elements include: Network Interface Cards Network topology Network cabling The type of signals used for data transmittions In this question, the network engineer flippedthe laptop's wireless switch on to resolve the issue. The laptop was unable to connect to the wireless network because the wireless network interface card was switched off. Switching the wireless network interface card on enabled the laptop to connect to the wireless network. The wireless network interface card is a physical layer device.
