Q

A network technician is configuring a wireless access point and wants to only allow company-owned devices to associate with the network. The access point uses PSKs, and a network authentication system does not exist on the network. Which of the following should the technician implement?
A.Captive portal
B.Guest network isolation
C.MAC filtering
D.Geofencing

A

Answer: C

Explanation:
C. MAC filteringTo only allow company-owned devices to associate with the wireless network when using PSKs (Pre-Shared Keys) and in the absence of a network authentication system, the network technician should implement MAC filtering. MAC filtering involves creating a whitelist of allowed MAC addresses (the unique hardware addresses of network interfaces) that are permitted to connect to the wireless network.By configuring MAC filtering on the wireless access point, only devices with MAC addresses specified in the whitelist will be allowed to associate with the network.Therefore, the correct answer is C. MAC filtering.

Q

A network administrator received reports that a 40Gb connection is saturated. The only server the administrator can use for data collection in that location has a 10GB connection to the network. Which of the following is the best method to use on the server to determine the source of the saturation?
A.Port mirroring
B.Log aggregation
C.Flow data
D.Packet capture

A

Answer: C

Explanation:
C. Flow data. Flow data, collected through flow monitoring protocols such as Net Flow, s Flow, or IPFIX, provides aggregated information about network traffic, including details on source and destination IP addresses, ports, protocols, and more. This method doesn’t capture the actual packet contents but summarizes network traffic flow. By leveraging flow data, the network administrator can gather information about the traffic patterns and bandwidth usage across the network. This method is less resource-intensive than performing packet captures and can provide valuable insights into the sources and destinations of the traffic causing the saturation on the 40Gb connection.

Q

A network engineer performed a migration to a new mail server. The engineer changed the MX record, verified the change was accurate, and confirmed the new mail server was reachable via the IP address in the A record. However, users are not receiving email. Which of the following should the engineer have done to prevent the issue from occurring?
A.Change the email client configuration to match the MX record.
B.Reduce the TTL record prior to the MX record change.
C.Perform a DNS zone transfer prior to the MX record change.
D.Update the NS record to reflect the IP address change.

A

Answer: B

Explanation:
B. Reduce the TTL (Time To Live) record prior to the MX record change.TTL (Time To Live): TTL is a value in a DNS record that determines the amount of time it can be cached by DNS resolvers and other devices on the internet. When making changes to DNS records, reducing the TTL beforehand helps minimize the time it takes for the changes to propagate throughout the internet.MX Record Change: Changing the MX (Mail Exchange) record directs email traffic to the specified mail server. However, DNS changes take time to propagate across the internet due to caching. If the TTL is set too high, old records may be cached for an extended period, leading to email delivery issues.

Q

Which of the following layers of the OSI model is responsible for end-to-end encryption?
A.Presentation
B.Application
C.Session
D.Transport

A

Answer: A

Explanation:
A. Presentation.

The Presentation layer of the OSI model is primarily responsible for formatting, encrypting, and compressing data in a way that the Application layer can understand. Encryption, as a part of data formatting, is often implemented in this layer to ensure end-to-end secure communication between applications.

While encryption can also be implemented at other layers of the OSI model, such as the Application layer (for application-specific encryption) and the Transport layer (for transport-level encryption such as SSL/TLS), the Presentation layer specifically deals with the syntax and semantics of the data to be exchanged and is where data encryption/decryption often takes place, allowing for secure communication between applications.

A client wants to increase overall security after a recent breach. Which of the following would be best to implement? (Choose two.)

A.Least privilege network access
B.Dynamic inventories
C.Central policy management
D.Zero-touch provisioning
E.Configuration drift prevention
F.Subnet range limits

A

Answer: AC

Explanation:
A. 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.C. 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.

Users are moving back into an office that had been vacant for a while. Ten workstations are hooked up in the office, but one workstation cannot obtain a link with the switch. A network engineer checks the documentation and cable labeling, and everything is hooked up as expected. The engineer moves the connection to a different switchport. but a link still cannot be obtained. When the engineer puts a tone generator on the infrastructure cable, no tone is heard at the far end. Which of the following issues is the engineer MOST likely trying to find?
A.A bad switchport
B.A break in the cable
C.A cable short
D.Cable interference

A

Answer: B

Explanation:
B. A break in the cableGiven the scenario where moving the connection to a different switch port did not resolve the issue and no tone is heard at the far end when using a tone generator on the infrastructure cable, the engineer is most likely trying to find a break in the cable. The absence of a tone signal at the far end indicates a discontinuity or complete break in the cable, which prevents the signal from traveling the entire length of the cable. This would also explain why the workstation cannot obtain a link with the switch, as the physical pathway for the network connection is interrupted.

22
Q

Which of the following services provides the network information for the address when IPv6 is used for SLAAC addressing?
A.EUI-64
B.IPv6 unicast routing
C.Router advertisement
D.DHCPv6

A

Answer: C

Explanation:
C. Router advertisement

Router advertisement messages are used in IPv6 networks to advertise routing information, including network prefixes, to hosts. When SLAAC is used, routers send router advertisement messages periodically, informing hosts about the network’s prefix, which the hosts then use to generate their IPv6 addresses. This process allows hosts to configure their own IPv6 addresses without the need for a DHCPv6 server.

A network administrator for a small office is adding a passive IDS to its network switch for the purpose of inspecting network traffic. Which of the following should the administrator use?
A.SNMP trap
B.Port mirroring
C.Syslog collection
D.API integration

A

Answer: B

Explanation:
Port mirroring (also known as SPAN - Switched Port Analyzer) is the process of forwarding a copy of network packets from one port on a network switch to another port, where the packets can be analyzed. In this scenario, the network administrator should use port mirroring to send a copy of the network traffic to the passive IDS (Intrusion Detection System) for inspection without interrupting the normal flow of traffic on the network. This allows the IDS to monitor the network traffic and detect any suspicious or malicious activity.

Q

Which of the following routing technologies uses a successor and a feasible successor?
A.IS-IS
B.OSPF
C.BGP
D.EIGRP

A

Answer: D

Explanation:
EIGRP (Enhanced Interior Gateway Routing Protocol) utilizes both successor and feasible successor concepts for routing:Successor: The primary path to a destination with the best metric (lowest cost). This route gets installed in the routing table and is used for forwarding traffic.Feasible Successor: A backup path considered a viable alternative if the primary route fails. It meets specific criteria (feasible distance) but doesn’t have the absolute best metric. This route is stored in the topology table and can be immediately used for traffic forwarding if the successor goes down.

A company is sending a switch to a remote site to be reused. An administrator needs to move the switch and ensure no network settings persist. Which of the following databases does the administrator need to delete?
A.VLAN
B.STP
C.ARP
D.Trunking

A

Answer: C

Explanation:
C. ARP (Address Resolution Protocol)When reusing a switch at a remote site and wanting to ensure that no network settings persist, the administrator should delete the ARP (Address Resolution Protocol) cache. ARP maintains a mapping between IP addresses and MAC addresses in a table, and clearing the ARP cache helps prevent any potential conflicts or issues when connecting the switch to a new network.Options A (VLAN), B (STP), and D (Trunking) are not databases but rather configuration settings that may need attention depending on the specific requirements of the new network. Deleting VLAN configurations, spanning tree protocol settings, or trunking configurations may be necessary, but they are not referred to as databases.
