An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500.Traffic destined to AS 111 network 91 7 0.0/16 should come in via AS 100. while traffic destined to all other networks in AS
111 should continue to use the existing path Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 Into the 91.7.0.0/16 network?

• A.Prepend AS path for the 91.7.0.0/16 network and set it for neighbor in AS 200.
• B.Set higher MED for neighbor in AS 100 to influence incoming traffic for the 91. 7.0.0/16 network.
• C.Use extended community for the 91.7.0.0/16 network, not advertising it to the bi-lateral peer.
• D.Use local preference on R1 for the networks that AS 500 advertises to AS 111.

An IT service provider is upgrading network infrastructure to comply with PCI security standards. The network team finds that 802.1X and VPN authentication based on locally-significant certificates are not available on some legacy phones.
Which workaround solution meets the requirement?

• A.Temporarily allow fallback to TLS 1.0 when using certificates and then upgrade the software on legacy phones.
• B.Enable phone VPN authentication based on end-user username and password.
• C.Use authentication-based clear text password with no EAP-MD5 on the legacy phones.
• D.Replace legacy phones with new phones because the legacy phones will lose trust if the certificate is renewed.

Company XYZ wants to redesign the Layer 2 part of their network and wants to use all available uplinks for increased performance. They also want to have end host reachability supporting conversational learning. However, due to design constraints, they cannot implement port-channel on the uplinks. Which other technique can be used to make sure the uplinks are in active/active state?

• A.TRILL
• B.MSTP
• C.switch stack
• D.LISP

This network is running legacy STP 802.1 d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

• A.Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
• B.The transit_delay=5 and dpdu_delay=20 are recommended values, considering helto_timer=2 and specified
• C.Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802. to speed up STP convergence process
• D.The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
