The current software on the Intelligent Resilient Framework (IRF) virtual device shown in the exhibit is version 1104. The network administrator wants to upgrade to software version 1105.
What will happen when the administrator attempts to use In-Service Software Upgrade (ISSU) for this upgrade?

• A.  When the administrator executes the switch over to the new master, a rollback will occur, causing the software to revert to the previous version.
• B.  The IRF virtual device will not accept the ISSU commands. It will output various error messages.
• C.  The process can complete successfully. Some links might go down, causing temporary failovers within link aggregation groups.
• D.  When the administrator executes the switchover to the new master, an outage will occur while this master reboots.

• A.  On trk2
• B.  On trk1 and trk3
• C.  On trk1, trk2, trk3
• D.  On trk2 and the peer keepalive

How does virtual output queuing (VoQ) help switches avoid head-of-line blocking and enhance throughput?

• A.  It divides each port ingress queue into different queues based on the priority and egress port of each packet
• B.  It establishes a matrix of connections to multiple cross-bar switches within the switch backplane
• C.  It allows the ingress port to fragment packets and send the fragments in multiple queues over different crossbars
• D.  It considers traffic congestion, queues traffic, and informs the ingress port when it can use the crossbar

• A.  It forwards the traffic without remarking it in any way
• B.  It forwards the traffic but marks it for forwarding in a lower priority queue
• C.  It drops the traffic
• D.  It forwards the traffic but marks it yellow (for a higher drop precedence)
