A.    The region name is configured the same on both devices.B.    The VLAN mapping is configured incorrectly.C.    The MSTP revision is configured incorrectly.D.    The bridge priority has not been configured correctly. Answer: C QUESTION 44A network engineer has configured MSTP on several switches for loop protection. You must verify the work and ensure that the appropriate parameters match on all switches.MSTP informationContext identifier : 0Region name : JuniperRevision : 1Configuration digest : 0xfdbe318c0ae799ae6dfdae4c882c67eeMSTI Member VLANs0 0,4-40941 1-3Which operational command provides the required output shown in the exhibit?

A.    The bridge priority values of MSTI 2 are the same.B.    There is a VLAN mismatch between the two switches for MSTI 2.C.    There is a bridge priority mismatch.D.    MSTI 1 and MSTI 2 are part of the same the MSTP region. Answer: B QUESTION 46Your company makes extensive use of VSTP in your network for loop protection. The network is at the VSTP VLAN limit and must protect additional VLANs.Which command allows you to protect additional VLANs? A.    set protocols mstp interface allB.    set protocols vstp vlan allC.    set protocols vstp vlan-groupD.    set protocols rstp Answer: D QUESTION 47You are asked to set up 802.1X port authentication for all access ports on your EX Series switch. You must ensure that only one user is allowed to authenticate per port and all other attempts are denied.Which supplicant mode must be used? A.    single modeB.    single-secure modeC.    default modeD.    multiple mode Answer: B QUESTION 48You are asked to set up 802.1X port authentication for all access ports on your EX Series switch. You have a device that does not support 802.1X supplicants and you must ensure this device is authenticated. You must also ensure that no unnecessary delay occurs when authenticating this device.Which statement is correct? A.    You should enable MAC RADIUS on the interface and use 802.1X multiple mode.B.    You should enable MAC RADIUS on the interface and statically add the MAC address to the 802.1x configuration.C.    You should enable MAC RADIUS on the interface and include the restrict parameter.D.    You should enable MAC RADIUS on the interface and include the disable parameter. Answer: C QUESTION 49Your company uses 802.1X to authenticate your users. You want to provide access to the Internet when users cannot authenticate on the RADIUS server or when the RADIUS server becomes unreachable.Which two methods accomplish this goal? (Choose two.) A.    using a captive portalB.    using a server fail fallbackC.    using MAC RADIUSD.    using a guest VLAN Answer: BD QUESTION 50Your company recently implemented Layer 2 authentication and access control to secure users accessing the corporate network. You implemented 802.1X, MAC RADIUS, and a captive portal to support a variety of hosts on the network. Senior management is concerned that valid users might be authenticated incorrectly on the network and they ask you questions about how these different access technologies are used simultaneously.Which three statements are correct? (Choose three.) A.    MAC addresses that are part of a MAC address whitelist or a static MAC list are authenticated before any other authentication protocol is invoked.B.    Captive portal is a supported fallback option for 802.1X.C.    If the authentication server fails to respond to access requests and both a server-fail and guest VLAN are configured correctly, the server-fail VLAN takes precedence over the guest VLAN.D.    Captive portal can only be configured on Layer 3 interfaces.E.    If a port is configured with 802.1X and the host does not respond to EAP requests, no other authentication protocol can authenticate the host.
