• Question 681:

  A technician thinks one of the router ports is flapping. Which of the following available resources should the technician use in order to determine if the router is flapping?

  A. Audit logs
  B. NetFlow
  C. Syslog
  D. Traffic logs
  C. Syslog

  ---

  Explanation/Reference:

  Syslog is a protocol that allows network devices to send event messages to a centralized server or console for logging and analysis1. Syslog can help a technician to determine if a router port is flapping by providing timestamps, severity levels, and descriptions of the events that occur on the router, such as interface up or down, link state change, or error messages. Syslog can also help to identify the cause and frequency of the port flapping and troubleshoot the issue. Audit logs are records of actions or events that occur on a system or network, such as user login, file access, configuration change, or policy violation. Audit logs can help to monitor and verify the activities and behaviors of users, devices, or applications on a system or network. Audit logs can also help to detect and investigate security incidents, compliance issues, or performance problems. However, audit logs do not provide detailed information about router port flapping. NetFlow is a protocol that collects and analyzes network traffic data for monitoring and troubleshooting purposes2. NetFlow can help to identify the sources, destinations, volumes, and types of traffic on a network. NetFlow can also help to optimize network performance, security, and capacity planning. However, NetFlow does not provide detailed information about router port flapping. Traffic logs are records of network traffic that pass through a device or application, such as a firewall, proxy, or web server. Traffic logs can help to monitor and filter the network traffic based on rules or policies. Traffic logs can also help to detect and prevent malicious traffic, such as malware, attacks, or unauthorized access. However, traffic logs do not provide detailed information about router port flapping.

• Question 682:

  A company wants to invest in new hardware for the core network infrastructure. The management team requires that the infrastructure be capable of being repaired in less than 60 minutes if any major part fails. Which of the following metrics is MOST likely associated with this requirement?

  A. RPO
  B. MTTR
  C. FHRP
  D. MTBF
  B. MTTR

  ---

  Explanation/Reference:

  MTTR is directly related to how quickly a system can be repaired if any major part fails3. The management team requires that the infrastructure be capable of being repaired in less than 60 minutes, which means they have a low MTTR requirement. MTTR stands for Mean Time To Repair and is a metric used to measure the average amount of time it takes to repair a failed component or system. In this case, the requirement is for the infrastructure to be capable of being repaired in less than 60 minutes if any major part fails, which means the MTTR should be less than 60 minutes.

• Question 683:

  Kim, a network administrator, should consult which documentation sources FIRST to determine the cause of recent network issues?

  A. Network map
  B. Cable management
  C. Change management
  D. Asset management
  C. Change management

  E. Distance limitation
  A. Bad switchport

• Question 685:

  A corporation is looking for a method to secure all traffic between a branch office and its data center in order to provide a zero-touch experience for all staff members who work there. Which of the following would BEST meet this requirement?

  A. Site-to-site VPN
  B. VNC
  C. Remote desktop gateway
  D. Virtual LANs
  A. Site-to-site VPN

  ---

  Explanation/Reference:

  A site-to-site VPN is a method that creates a secure and encrypted connection between two internet gateways, such as routers or firewalls, that belong to different networks1. A site-to-site VPN can secure all traffic between a branch office and its data center by creating a virtual tunnel that protects the data from interception or tampering. A site-to-site VPN can also provide a zero-touch experience for all staff members who work there, as they do not need to install any software or configure any settings on their devices to access the data center resources. They can simply use their local network as if they were physically connected to the data center network. VNC (Virtual Network Computing) is a method that allows remote access and control of a computer's desktop from another device over a network2. VNC can enable staff members to work remotely by accessing their office computers from their home computers or mobile devices. However, VNC does not secure all traffic between a branch office and its data center, as it only works at the application layer and does not encrypt the network layer. VNC also does not provide a zero-touch experience for staff members, as they need to install software and configure settings on both the host and the client devices. Remote desktop gateway is a method that allows remote access and control of a computer's desktop from another device over a network using the Remote Desktop Protocol (RDP). Remote desktop gateway can also enable staff members to work remotely by accessing their office computers from their home computers or mobile devices. However, remote desktop gateway does not secure all traffic between a branch office and its data center, as it only works at the application layer and does not encrypt the network layer. Remote desktop gateway also does not provide a zero-touch experience for staff members, as they need to install software and configure settings on both the host and the client devices. Virtual LANs (VLANs) are methods that create logical subdivisions of a physical network based on criteria such as function, department, or security level. VLANs can improve network performance, security, and management by reducing broadcast domains, isolating traffic, and enforcing policies. However, VLANs do not secure all traffic between a branch office and its data center, as they only work at the data link layer and do not encrypt the network layer. VLANs also do not provide a zero-touch experience for staff members, as they need to configure settings on their network devices to join or leave a VLAN.

• Question 686:

  A company is considering shifting its business to the cloud. The management team is concerned at the availability of the third-party cloud service. Which of the following should the management team consult to determine the promised availability of the cloud provider?

  A. Memorandum of understanding
  B. Business continuity plan
  C. Disaster recovery plan
  D. Service-level agreement
  D. Service-level agreement

  ---

  Explanation/Reference:

  A Service-level agreement (SLA) is a document that outlines the responsibilities of a cloud service provider and the customer. It typically includes the agreed-upon availability of the cloud service provider, the expected uptime for the service, and the cost of any downtime or other service interruptions. Consulting the SLA is the best way for the management team to determine the promised availability of the cloud provider. Reference: CompTIA Cloud+ Study Guide, 6th Edition, page 28.

• Question 688:

  A network technician was troubleshooting an issue for a user who was being directed to cloned websites that were stealing credentials. The URLs were correct for the websites but an incorrect IP address was revealed when the technician

  used ping on the user's PC After checking the is setting, the technician found the DNS server address was incorrect.

  Which of the following describes the issue?

  A. Rogue DHCP server
  B. Misconfigured HSRP
  C. DNS poisoning
  D. Exhausted IP scope
  C. DNS poisoning

  ---

  Explanation/Reference:

  DNS poisoning is a type of attack that modifies the DNS records of a domain name to point to a malicious IP address instead of the legitimate one. This can result in users being directed to cloned websites that are stealing credentials, even if

  they enter the correct URL for the website. The incorrect DNS server address on the user's PC could be a sign of DNS poisoning, as the attacker could have compromised the DNS server or spoofed its response to redirect the user's queries.

• Question 689:

  A customer calls the help desk to report that users are unable to access any network resources. The issue started earlier in the day when an employee rearranged the wiring closet. A technician goes to the site but does not observe any obvious damage. The statistics output on the switch indicates high CPU usage, and all the lights on the switch are blinking rapidly in unison. Which of the following is the MOST likely explanation for these symptoms?

  A. The switch was rebooted and set to run in safe mode.
  B. The line between the switch and the upstream router was removed.
  C. A cable was looped and created a broadcast storm.
  D. A Cat 6 cable from the modem to the router was replaced with Cat 5e.
  C. A cable was looped and created a broadcast storm.

  ---

  Explanation/Reference:

  The symptoms, including high CPU usage and rapidly blinking switch lights, are most likely due to a cable loop in the network causing a broadcast storm, which is overwhelming network resources and disrupting connectivity.
