• Question 931:

  A network is experiencing a number of CRC errors during normal network communication. At which of the following layers of the OSI model will the administrator MOST likely start to troubleshoot?

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 4
  E. Layer 5
  F. Layer 6
  G. Layer 7
  A. Layer 1

  ---

  Explanation/Reference:

  CRC (Cyclic Redundancy Check) errors are often indicative of problems at the physical layer of communication because they often result from issues like interference, signal attenuation, or poor-quality cables. The physical layer corresponds to Layer 1 of the OSI model.

• Question 932:

  A network administrator is unable to identify the root cause of a network incident because insufficient evidence about the threat actor's actions was logged. The administrator notes that the server receiving and storing the events was not compromised by any attack and is properly communicating with all network devices.

  Which of the following can the administrator employ to improve network access accountability?

  A. Activate the audit logs on the network server and resources.
  B. Configure SNMP on the network server.
  C. Deploy a central SIEM server into the network.
  D. Collect traffic statistics from the servers using NetFlow data.
  C. Deploy a central SIEM server into the network.

• Question 933:

  A company is designing a SAN and would like to use STP as its medium for communication. Which of the following protocols would BEST suit the company's needs?

  A. SFTP
  B. Fibre Channel
  C. iSCSI
  D. FTP
  C. iSCSI

• Question 934:

  Which of the following types of datacenter architectures will MOST likely be used in a large SDN and can be extended beyond the data center? (Choose two.)

  A. iSCSI
  B. FCoE
  C. Three-tiered network

• Question 936:

  A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?

  A. Hosts file
  B. Self-signed certificate
  C. Nameserver record
  D. IP helper
  A. Hosts file

• Question 937:

  A network team has reopened multiple outages caused by unauthorized access to the IDF.

  Which of the following would BEST prevent this issue from reoccurring?

  A. Video surveillance
  B. Badge readers
  C. Motion sensors
  D. Tamper switches

• Question 938:

  A WAN technician reviews activity and identifies newly installed hardware that is causing outages over an eight-hour period. Which of the following should be considered FIRST?

  A. Network performance baselines
  B. VLAN assignments
  C. Routing table
  D. Device configuration review
  D. Device configuration review

  ---

  Explanation/Reference:

  The most likely cause of outages due to newly installed hardware is a misconfiguration of the device settings. Therefore, the first step should be to review the device configuration and check for any errors or inconsistencies that might affect the WAN connectivity.

• Question 939:

  Which of the following devices and encapsulations are found at the data link layer? (Choose two.)

  A. Session
  B. Frame
  C. Firewall
  D. Switch
  E. Packet
  F. Router
  B. Frame
  D. Switch

  ---

  Explanation/Reference:

  Frame: Frames are the units of data at the data link layer. They encapsulate packets and include control information such as MAC addresses and error detection codes. Switch: Switches operate at the data link layer and make forwarding decisions based on MAC addresses.

• Question 940:

  A network security engineer is responding to a security incident. The engineer suspects that an attacker used an authorized administrator account to make configuration changes to the boundary firewall. Which of the following should the network security engineer review?

  A. Network traffic logs
