- B. It permits both frames.
- C. It denies frame 1 and permits frame 2.
- D. It permits frame 1 and denies frame 2.
Answer: C
NEW QUESTION 7

- A. an SNMP trap
- B. an RMON alarm
- C. an auto-config server
- D. an sFlow instance
Answer: A
NEW QUESTION 8
A company wants to implement role-based tunneled node on AOS-Switches. Which solution should be included in the plan to help apply the roles?

- B. an SNMP server, such as Aruba AirWave
- C. Aruba Mobility Manager (MM)
- D. Aruba Meridian
Answer: A
NEW QUESTION 9
A network administrator sets up MAC-Auth and captive portal to Aruba ClearPass on AOS-Switches. The solution seems to work for most guests. However, some guests open their browsers and are not redirected to the captive portal. How should the administrator address the likely cause of the issue?
- A. Set the RADIUS server time window to 0 because some guest computers likely have the incorrect system time.
- B. Replace MAC-Auth on switch ports with Web-Auth because this authentication method offers more reliability with captive portal.
- C. Reconfigure the captive portal URL hash key on some of the switches, which likely have the wrong password.
- D. Replace expired certificates on the switches and set their usage to captive portal since some guests have an HTTPS homepage.
Answer: D
NEW QUESTION 10
Two AOS-Switches connect on VLAN 10 in OSPF Area 1, which is defined as a stub area on both. Which mismatch can cause OSPF routers to lose adjacency?
- A. The administrator adds the backbone area to just one of the routers.
- B. The administrator enables graceful restart, or nonstop switching, on just one of the routers.
- C. The administrator enables jumbo frames on VLAN 10 on just one of the routers.
- D. The administrator adds the no-summary option to Area 1 on just one of the router
Answer: B
NEW QUESTION 11
