QUESTION 86 You are a newly appointed Cisco Highway trainee. The Cisco Highway WAN is shown in the following exhibit: What are the broadcast addresses of the subnets in the Cisco Highway WAN? (Select three options.)
A. 172.16.82.255
B. 172.16.95.255
C. 172.16.64.255
D. 172.16.32.255
E. 172.16.47.255
F. 172.16.79.255 Answer: B E F Explanation: 172.16.23.0/20 has 16 increments and the broad cast address will always be 1 before the actual number. 172.16.23.0 next increment will be 172.16.39.0 so then the broadcast address is 1 less than 172.16.39.0 = 172.16.38.255 (Broadcast address).
QUESTION 87 One of your trainees wants to know which of the following mentioned below are represented in the router IOS file naming conventions. What can you tell her? (Select three options.)
A. Distribution channel failures
B. Feature capabilities
C. Memory capacity needs
D. Hardware product platform
E. Programming language requirements
F. Run location and compression status Answer: B D F Explanation: Image Naming Conventions You can identify the platform, features, and image location by the name of the image. The naming convention is platform-features-type for images that re stored on a UNIX system The platform variable indicates which platforms can use this image. Examples of platform variables include rsp (Cisco 7000 series with RSP7000 and Cisco 7500 series), c1600 (Cisco 1600 series), and c1005 (Cisco 1005). The features variable identifies the feature sets supported by the image. The type field can contain the following characters: f-The image runs from Flash memory. m-The image runs from RAM. r-The image runs from ROM. l-The image is relocatable.
z-The image is zip compressed. x-The image is mzip compressed. Source: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800 c6c63.php#1026053
