Correct Answer: B,C
Question 8
For user in local PPP Secrets/PPP Profiles database, it is possible to:
Correct Answer: A,B,D
The local PPP database in MikroTik allows control over authentication and access for PPP-based services such as PPTP, L2TP, PPPoE, and SSTP. Several configuration options can be specified per user or profile. * A.#Correct - You can use the "only-one" setting in PPP profiles to allow/deny multiple logins for the same user. * B.#Correct - Under the "service" parameter in /ppp secret, you can restrict allowed protocols (e.g., enable PPPoE, PPTP, and disable L2TP). * C.#Incorrect - Data transfer limits (Rx/Tx) are not enforced directly in PPP profiles or secrets. This is usually handled via queues or hotspot limitations. * D.#Correct - By setting the "service" to only "pppoe", all other PPP types will be denied. * E.#Incorrect - Access to services like telnet is managed via firewall rules or user groups, not in PPP profiles. Extract from Official MTCNA Course Material - PPP Profiles: "PPP Profiles control session parameters. You can limit simultaneous logins, restrict service types (e.g., PPPoE), and set IP pools." Extract from Rene Meneses MTCNA Study Guide - PPP Configuration: "Use the 'only-one' flag to control concurrent logins. The 'service' field allows or restricts protocol types per user." Extract from Terry Combs MTCNA Notes - PPP Features: "To allow a user access only via PPPoE or PPTP, adjust the service types in /ppp secret."
Question 9
Can you manually add drivers to RouterOS in case your PCI Ethernet card is not recognized, and you suspect it is a driver issue?
Correct Answer: B
RouterOS is a closed, embedded Linux-based system. It does not support adding custom drivers or compiling modules manually. You must use supported hardware that is natively compatible with RouterOS. MTCNA Course Material - RouterBOARD Compatibility: "RouterOS supports a fixed set of drivers. You cannot install third-party drivers or modules." Rene Meneses MTCNA Guide - Hardware Limitations: "Custom drivers cannot be added to RouterOS. Use only supported network interface cards as listed by MikroTik." MikroTik Wiki - Hardware Support: "RouterOS does not allow manual driver installation. All drivers are precompiled and built into the system image." Therefore, if your PCI Ethernet card is not recognized, you must replace it with a compatible model - you cannot add a driver manually.
