Question 97
What kind of users are listed in the Secrets window of the PPP menu?
Correct Answer: C,D,E
The /ppp secret menu is used in RouterOS to manage usernames and passwords for Point-to-Point Protocol (PPP) based services, including: * PPPoE (Point-to-Point Protocol over Ethernet) * PPTP (Point-to-Point Tunneling Protocol) * L2TP (Layer 2 Tunneling Protocol) It does not include HotSpot users, wireless clients, or Winbox users. MTCNA Course Material - PPP User Authentication: "The PPP secret database stores credentials for services like PPPoE, PPTP, and L2TP." Rene Meneses MTCNA Study Guide - PPP Configuration Section: "Users for PPP-based protocols are configured under PPP # Secrets. This includes PPPoE, PPTP, and L2TP." MikroTik Wiki - PPP Secrets Window: "Secrets are used to authenticate users for all PPP interfaces. HotSpot users are managed separately under /ip hotspot user." Option A: HotSpot users # /ip hotspot user Option B: Wireless users connect via WPA/802.11 - not listed in PPP Option F: Winbox users refer to /user under system user management Final answer: C, D, E
Question 98
When using routing option check-gateway=ping, after how many timeouts is the gateway considered unreachable?
Correct Answer: C
In MikroTik RouterOS, if you enable check-gateway=ping on a static route, RouterOS sends periodic ICMP echo requests (ping) to the specified gateway. By default, the gateway is considered unreachable after: * 2 consecutive ping timeouts ## This status will cause the router to remove the route from the routing table until the gateway responds again. Evaluations: * A. 4 ##Too many * B. 1 ##Too sensitive; only one timeout doesn't mark it unreachable * C. 2 ##Correct default behavior * D. 3 ##Incorrect default MTCNA Course Manual - Gateway Checking: "When using check-gateway=ping, the router waits for two failed pings before declaring the route inactive." Rene Meneses Study Guide - Static Routing Behavior: "check-gateway=ping disables the route after two ping failures." Terry Combs Notes - Route Monitoring: "Ping-based route checks fail after 2 missed responses - that route becomes inactive."
Question 99
Select which of the following are 'Public IP addresses':
Correct Answer: C
IP addresses are categorized as either public or private. According to the IANA (Internet Assigned Numbers Authority), the following are reserved for private use: * 10.0.0.0 to 10.255.255.255 (Class A Private) * 172.16.0.0 to 172.31.255.255 (Class B Private) * 192.168.0.0 to 192.168.255.255 (Class C Private) Any IP outside of these ranges is considered public and routable on the global internet. Evaluation of each option: * A. 172.168.254.2 # This is in the 172.16.0.0 - 172.31.255.255 range # Private * B. 172.28.73.21 # Also falls in the same private 172.16.0.0/12 range # Private * C. 11.63.72.21 # Outside all private ranges # Public# * D. 10.110.50.37 # In the 10.0.0.0/8 range # Private * E. 192.168.0.1 # In the 192.168.0.0/16 private range # Private Extract from Rene Meneses MTCNA Study Guide: "Private IP ranges include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These are non-routable over the public internet." Extract from Terry Combs Notes: "Only IPs outside of the above ranges are considered public and routable. Watch out for 172.X.X.X - not all are public; only 172.0.0.0-172.15.255.255 and 172.32.0.0+ are public." MikroTik Wiki - IP Addressing Reference: "Private addresses are not globally routable. They are used inside local networks and must be NATed for internet access."
