1. Question 491 · 1003 in bank

   A server running Linux is providing support for virtual machines along with DNS and DHCP services for a small business. Which technology does this represent?

   • Acontainer
   • BType 1 hypervisor
   • CType 2 hypervisor
   • Dhardware pass-thru

   Show answer

   Answer: C

   Explanation

   This question is really stupid and so is the discussion about type 1 and 2 hypervisors. ESX runs on linux just as much as... linux running kvm Stupid ambiguous question. But if I were to guess, I would say the answer is C because whoever wrote it doesn't consider anything except vmware a type 1 hypervisor. But who knows what that person was thinking.

   Rember boys and girls.. when reading an EIGRP question, any positive-sounding description is automatically EIGRP. "Quickly computes new paths?" - MUST BE EIGRP! "Can load-balance unequal cost LB?" - MUST BE EIGRP! Only CISCO DESIGNS THE BEST PROTOCOLS

5. Question 495 · 1003 in bank

   An engineer is configuring Local WebAuth on a Cisco Wireless LAN Controller. According to RFC 5737, which virtual IP address must be used in this configuration?

   • A172.20.10.1
   • B192.168.0.1
   • C1.1.1.1
   • D192.0.2.1

   Show answer

   Answer: D

   Explanation

   RFC 5737 specifies the use of the following blocks of IP addresses for documentation purposes: 192.0.2.0/24 (TEST-NET-1) 198.51.100.0/24 (TEST-NET-2) 203.0.113.0/24 (TEST-NET-3) These addresses are reserved for use in documentation and sample configurations and are not routable on the public Internet. The address 192.0.2.1 falls within the 192.0.2.0/24 range and is intended for such purposes, making it the correct choice for configuring Local WebAuth on a Cisco Wireless LAN Controller in this context.

7. Question 497 · 1003 in bank

   What is one benefit of adopting a data modeling language?

   • Aaugmenting the use of management protocols like SNMP for status subscriptions
   • Brefactoring vendor and platform specific configurations with widely compatible configurations
   • Caugmenting management process using vendor centric actions around models
   • Ddeploying machine-friendly codes to manage a high number of devices

   Show answer

   Answer: B

   Explanation

   I did not find any documents which would clearly exclude answer D, still, I am going for B. Consistency and standardization seem to be the main advantage of data models, which is more in line with answer B (vendor/platform independent). https://www.cisco.com/c/en/us/td/docs/iosxr/ncs5xx/programability/63x/b-programmability-cg-63x-ncs5xx/cg_63_data_models_scope_need_and_benefits.pdf "Data models can be used to automate configuration tasks across heterogeneous devices in a network." https://developer.cisco.com/docs/ios-xe/#!model-based-management-introduction/data-models Open Models are supported for IOS-XE. "Open models are models designed to be independent of the underlying platform implementation." https://www.cisco.com/c/en/us/td/docs/iosxr/ncs5xx/programability/63x/b-programmability-cg-63x-ncs5xx/cg_63_data_models_scope_need_and_benefits.pdf Although this document reads "automating the configuration using data models results in scalability." Scalability seems to be linked rather to hierarchical network design.

9. Question 499 · 1003 in bank

   An engineer must configure a new WLAN that allows a user to enter a passphrase and provides forward secrecy as a security measure. Which Layer 2 WLAN configuration is required on the Cisco WLC?

   • AWPA3 Enterprise
   • BWPA2 Personal
   • CWPA2 Enterprise
   • DWPA3 Personal

   Show answer

   Answer: D

   Explanation

   D is correct WPA3-Personal provides the following key advantages: • Creates a shared secret that is different for each SAE authentication. • Protects against brute force “dictionary” attacks and passive attacks. • Provides forward secrecy. <--- Reference: https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9100ax-access-points/wpa3-dep-guide-og.pdf WPA3 Personal provides forward secrecy.
