   Answer: See figure below

   Explanation

   Going to take the first whack at this: Router A: Problem found: Yes Destination Prefix: 10.0.5.0 Destination Mask: 255.255.255.0 Interface: Gi1 Router B: Problem Found: Yes Destination Prefix: 10.0.1.0 Destination Mask: 255.255.255.0 Interface: Gi2 Router C: Problem Found: Yes Destination Prefix: 10.0.5.0 Destination Mask: 255.255.255.0 Interface: Gi2 However, I think Router C also needs an additional route for 10.0.1.0/24, no? Agree or disagree with any of the above?

2. Question 632 · 871 in bank

   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?

   • AA bad switchport
   • BA break in the cable
   • CA cable short
   • DCable interference

   Show answer

   Answer: B

   Explanation

   B. A break in the cable Given 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.

3. Question 633 · 871 in bank

   A network administrator is working to configure a new device to provide Layer 2 connectivity to various endpoints including several WAPs. Which of the following devices will the administrator MOST likely configure?

   • AWLAN controller
   • BCable modem
   • CLoad balancer
   • DSwitch
   • EHub

   Show answer

   Answer: D

   Explanation

   D. Switch The network administrator will most likely configure a switch to provide Layer 2 connectivity to various endpoints, including several Wireless Access Points (WAPs). A switch operates at the Data Link layer (Layer 2) of the OSI model and is used to connect devices within a LAN, facilitating communication by forwarding data based on MAC addresses. It allows multiple devices, like computers, servers, and WAPs, to communicate with each other within the same network segment efficiently.

5. Question 635 · 871 in bank

   Which of the following is an advantage of using the cloud as a redundant data center?

   • AThe process of changing cloud providers is easy.
   • BBetter security for company data is provided.
   • CThe initial capital expenses are lower.
   • DThe need for backups is eliminated.

   Show answer

   Answer: C

   Explanation

   C. The initial capital expenses are lower. Using the cloud as a redundant data center has the advantage of lower initial capital expenses compared to setting up and maintaining a physical data center. Cloud services typically operate on a pay-as-you-go or subscription model, which means companies can scale up their infrastructure as needed without the upfront costs associated with purchasing hardware, software, and real estate or investing in long-term maintenance and staffing. This financial flexibility is one of the key reasons many organizations opt for cloud solutions for redundancy and disaster recovery.

6. Question 636 · 871 in bank

   A network administrator corrected a rule on a misconfigured firewall. Which of the following should the administrator do NEXT when applying the network troubleshooting methodology?

   • AVerify full system functionality.
   • BDocument actions and lessons learned.
   • CEstablish a theory of probable cause.
   • DIdentify potential effects.

   Show answer

   Answer: A

   Explanation

   A. Verify full system functionality. After correcting a rule on a misconfigured firewall, the next step in applying the network troubleshooting methodology is to verify full system functionality and ensure that the correction has resolved the issue without causing additional problems. This involves testing the network to confirm that it operates as expected under normal conditions and that the initial problem has been effectively resolved. Verification is crucial to ensure that the changes made have indeed fixed the issue and that there are no unintended side effects.

7. Question 637 · 871 in bank

   Which of the following technologies would MOST likely be used to prevent the loss of connection between a virtual server and network storage devices?

   • AMultipathing
   • BVRRP
   • CPort aggregation
   • DNIC teaming

   Show answer

   Answer: A

   Explanation

   From VMWare https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-DD2FFAA7-796E-414C-84CE-1FCC14474D5B.html "To maintain a constant connection between a host and its storage, ESXi supports multipathing. With multipathing, you can use more than one physical path that transfers data between the host and an external storage device. If a failure of any element in the SAN network, such as an adapter, switch, or cable, occurs, ESXi can switch to another viable physical path. This process of path switching to avoid failed components is known as path failover. In addition to path failover, multipathing provides load balancing. Load balancing is the process of distributing I/O loads across multiple physical paths. Load balancing reduces or removes potential bottlenecks."

8. Question 638 · 871 in bank

   Which of the following services provides the network information for the address when IPv6 is used for SLAAC addressing?

   • AEUI-64
   • BIPv6 unicast routing
   • CRouter advertisement
   • DDHCPv6

   Show answer

   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.

9. Question 639 · 871 in bank

   A network engineer needs to enable device monitoring using authentication and encryption. Which of the following protocols offers this option?

   • AESP
   • BSNMPv3
   • CNetFlow
   • DSSLv3

   Show answer

   Answer: B

   Explanation

   B. SNMPv3 SNMPv3 (Simple Network Management Protocol version 3) offers the option to enable device monitoring with authentication and encryption, making it suitable for secure network management tasks. SNMPv3 enhances the security features of its predecessors by providing secure access to devices through a combination of authentication and encryption, ensuring that only authorized users can monitor and manage network devices and that the data exchanged is protected from eavesdropping.

10. Question 640 · 871 in bank

    Which of the following can be used to centrally manage credentials for various types of administrative privileges on configured network devices?

    • ASSO
    • BTACACS+
    • CZero Trust
    • DSeparation of duties
    • EMultifactor authentication

    Show answer

    Answer: B

    Explanation

    B. TACACS+ (Terminal Access Controller Access Control System Plus) is the correct answer as it is used to centrally manage credentials for various types of administrative privileges on configured network devices. A. SSO (Single Sign-On) is a method of access control that allows users to log in once and gain access to multiple systems without being prompted to log in again. C. Zero Trust is a security model that assumes that all network traffic is untrusted until proven otherwise. D. Separation of duties is a security principle that ensures that no single individual has complete control over a critical process. E. Multifactor authentication is a method of access control that requires users to provide two or more forms of authentication to access a system.
