  1. Ensure each device accesses only its correctly associated network

  2. Disable all unused switch ports

  3. Require fault-tolerant connections between the switches

  4. Only make necessary changes to complete the above requirements

  Switch 1 and Switch 2 is the only two switches that can be configured. Only switches linked together with there switch ports needs to be "tagged" and "LACP" needs to be enabled. The other ports must be untagged with no LACP enabled.

  You only need to assign the correct vlan via each port. 'Speed and Duplex' needs to be Speed=1000 and Duplex=Full, with is by default.

• Question 1072:

  Users are reporting performance issues when attempting to access the main fileshare server. Which of the following steps should a network administrator perform next based on the network troubleshooting methodology?

  A. Implement a fix to resolve the connectivity issues.
  B. Determine if anything has changed.
  C. Establish a theory of probable cause.
  D. Document all findings, actions, and lessons learned.
  B. Determine if anything has changed.

  ---

  Explanation/Reference:

  According to the network troubleshooting methodology, the first step is to identify the problem and gather information about the current state of the network using the network troubleshooting tools that are available1. The next step is to determine if anything has changed in the network configuration, environment, or usage that could have caused or contributed to the performance issues1. This step helps to narrow down the possible causes and eliminate irrelevant factors. For example, the network administrator could check if there were any recent updates, patches, or modifications to the fileshare server or the network devices that connect to it. They could also check if there was an increase in network traffic or demand for the fileshare server resources2. The other options are not correct because they are not the next steps in the network troubleshooting methodology. Implementing a fix to resolve the connectivity issues (A) is premature without determining the root cause of the problem. Establishing a theory of probable cause ?is a later step that requires testing and verification. Documenting all findings, actions, and lessons learned (D) is the final step that should be done after resolving the problem and restoring normal network operations1.

• Question 1073:

  A systems administrator is configuring a firewall using NAT with PAT. Which of the following would be BEST suited for the LAN interface?

  A. 172.15.0.0/18
  B. 172.18.0.0/10
  C. 172.23.0.0/16
  D. 172.28.0.0/8
  E. 172.32.0.0/14
  C. 172.23.0.0/16

  ---

  Explanation/Reference:

  NAT and PAT translate private IPs to public IPs, so we're seeking a private IP.

  Addresses 172.16.0.0 - 172.31.255.255 are private, excluding options A and E.

  Using CIDR, consider the remaining answers:

  Answer B) 172.18.0.0/10 has subnet mask 255.192.0.0 (10 network bits).

  To find network address we need to do a bitwise "AND" operation with the IP and subnet mask:

  Comparing bits side by side. If both bits are 1 it's a 1. If any bit is a 0 it's a 0.

  Subnet mask: 11111111.11000000.00000000.00000000(255.192.0.0)

  IP address: 10101100.00010010.00000000.00000000(172.18.0.0)

  Result: 10101100.00000000.00000000.00000000 (172.0.0.0)

  Network: 172.0.0.0

  Range: 172.0.0.1-172.63.255.254

  Broadcast: 172.63.255.255

• Question 1074:

  Access to a datacenter should be individually recorded by a card reader even when multiple employees enter the facility at the same time. Which of the following allows the enforcement of this policy?

  A. Motion detection
  B. Access control vestibules
  C. Smart lockers
  D. Cameras
  B. Access control vestibules

  ---

  Explanation/Reference:

  Access control vestibules can ensure that each individual's entry into the datacenter is separately recorded by a card reader, even when multiple employees enter the facility at the same time. Access control vestibules are small rooms with two doors that require authorized individuals to present their access cards to enter or exit. The vestibules ensure that only authorized individuals enter the datacenter, and their entry is individually recorded by the card reader. Once the first door is closed, the employee must present their card again to enter the second door. This double-entry system ensures that access to the datacenter is controlled and recorded accurately.

• Question 1075:

  Which of the following is the primary function of the core layer of the three-tiered model?

  A. Routing
  B. Repeating
  C. Bridging
  D. Switching
  A. Routing

  ---

  Explanation/Reference:

  https://www.omnisecu.com/cisco-certified-network-associate-ccna/three-tier-hierarchical-network-model.php

  Core Layer consists of biggest, fastest, and most expensive routers with the highest model numbers and Core Layer is considered as the back bone of networks. Core Layer routers are used to merge geographically separated networks. The Core Layer routers move information on the network as fast as possible. The switches operating at core layer switches packets as fast as possible.

• Question 1076:

  An engineer was asked to update an MX record for an upcoming project. Which of the following server types is MOST likely to be in scope for the project?

  A. Email
  B. Web
  C. File
  D. Database
  A. Email

  ---

  Explanation/Reference:

  An MX record is a type of DNS record that specifies the mail server responsible for accepting email messages on behalf of a domain name. Therefore, an engineer who needs to update an MX record is most likely working on an email server project

• Question 1077:

  A network technician is implementing a solution that will allow end users to gain access to multiple applications after logging on. Which of the following authentication methods would allow this type of access?

  A. SSO
  B. LDAP
  C. EAP
  D. TACACS+
  A. SSO

  ---

  Explanation/Reference:

  Single sign-on (SSO) is an authentication method that enables users to securely authenticate with multiple applications and websites by using just one set of credentials.

• Question 1078:

  A technician is configuring a wireless network and needs to ensure users agree to an AUP before connecting. Which of the following should be implemented to achieve this goal?

  A. Captive portal
  B. Geofencing
  C. Wireless client isolation
  D. Role-based access
  A. Captive portal

  ---

  Explanation/Reference:

  A captive portal is a web page that is displayed to users before they are able to access the internet or other network resources. It is commonly used to require users to agree to an Acceptable Use Policy (AUP) before they are able to connect to a wireless network.

• Question 1079:

  A network device is configured to send critical events to a syslog server; however, the following alerts are not being received:

  1.

  Severity 5 LINK-UPDOWN: Interface 1/1, changed state to down

  2.

  Severity 5 LINK-UPDOWN: Interface 1/3, changed state to down

  Which of the following describes the reason why the events are not being received?

  A. The network device is not configured to log that level to the syslog server
  B. The network device was down and could not send the event
  C. The syslog server is not compatible with the network device
  D. The syslog server did not have the correct MIB loaded to receive the message
  A. The network device is not configured to log that level to the syslog server

  ---

  Explanation/Reference:

  The syslog severity levels are 0 (Emergency), 1 (Alert), 2 (Critical), 3 (Error), 4 (Warning), 5 (Notice/Notification), 6 (Information), and 7 (Debugging). An easy mnemonic to memorize this is "Emus Are Cute Even When In Disguise." Because the device is set to send CRITICAL events, it will send only events that have a severity level of 2 and below. Thus, you have to configure the device to send events at severity level 5 or higher.

• Question 1080:

  A. Add a POE injector
  B. Enable MDIX.
  C. Use a crossover cable.
  D. Reconfigure the port.
  A. Add a POE injector
