N10-008 Online Practice Questions and Answers

Correct Answer: C

A warm site is a type of disaster recovery site that has equipment ready to go in the event of a disaster at the main datacenter, but does not have live data or applications. A warm site requires some time and effort to restore the data and services from backups, but it is less expensive than a hot site that has live data and applications. A cold site is a disaster recovery site that has no equipment or data, and requires a lot of time and money to set up after a disaster. A cloud site is a disaster recovery site that uses cloud computing resources to provide data and services, but it may have issues with bandwidth, latency, security, and cost.

Correct Answer: DG

Correct Answer: B

A water sensor is a type of environmental sensor that detects the presence of water or moisture in an area. A water sensor is most needed in a network main distribution frame (MDF) that is located in a basement near underground fiber-optic cables. A network MDF is a central point where all the network connections converge and where network equipment such as switches and routers are located. If water leaks into the basement and damages the fiber-optic cables or the network equipment, it can cause network outages, performance degradation, or data loss. A water sensor can alert the network administrator of any water intrusion and help prevent or minimize the damage.

Correct Answer: CD

The "community: public" line indicates that the default community string "public" is being used for SNMP requests. This is a well-known community string that is often used for testing but should not be used in production environments. Changing the community string to a private, unique value is essential to prevent unauthorized access. Only devices with the correct community string can access SNMP data.

SNMPv3 is the most secure version of SNMP. It provides authentication, data integrity, and encryption features to protect SNMP traffic. By using SNMPv3, the administrator can ensure that SNMP traffic is secure and protected from unauthorized access and data tampering.

Correct Answer: BD

The data link layer is responsible for defining the format of data on the network and providing physical transmission of data. Devices that operate at this layer include switches and network interface cards (NICs). Encapsulations that are used at this layer include frames, which are units of data that contain a header, payload, and trailer. Frames are used to identify the source and destination of data on the network and to perform error detection.

Correct Answer: A

CRC errors and/or late collisions can be caused by a duplex mismatch. When one site of a link is configured on full-duplex and the other on half-duplex you will see the CRC errors at the interface which is configured on full-duplex. This problem occurs also when one site of a link is configured on auto-duplex and the other fixed (full-duplex).

Correct Answer: AC

Least privilege network access: Implementing the principle of least privilege ensures that users and systems have only the minimum levels of access or permissions necessary to perform their functions. This helps to limit the potential impact of security breaches. Central policy management: Centralized policy management allows for consistent application of security policies across the entire network. This ensures that security settings are centrally configured, monitored, and enforced, reducing the likelihood of misconfigurations or oversights that could lead to security vulnerabilities.

While all the options listed can contribute to overall security, the two mentioned above are particularly effective in controlling access and managing security policies, which are crucial aspects of post-breach security measures.
