Scroll up to the Exam Topics section for the complete breakdown, and use it to plan how much study time each domain deserves.
Question 1
Which statement describes a step in provisioning SPBM in an enterprise network?
A. Enable SPBM and IS-IS globally on all nodes and on the core facing links.
B. Configure L2 and L3 VSNs on the core SPBM nodes.
C. Configure the MAC table.
D. Configure IP addresses on the core links.
Question 2
A technician discovers that an Ethernet Routing Switch (ERS) 8300 cat5e copper link is intermittent. The link connects a distant workstation to 8348GTX port 6/2. The cable path is undetermined at this point and it is suspected to traverse many patch panels. How can the
ERS 8300 Time Domain reflectometer tool be of help in this situation?
A. The Virtual Circuit Detect command config ethernet 6/2 vct detect can detect how many patch panels are used between the device and switch and provide a percentage of dropped packets.
B. The Virtual Circuit Echo command config ethernet 6/2 vct echo can detect the bad cable pairs only when connected to another ERS 8300.
C. The virtual circuit Repair command config ethernet 6/2 vct repair can detect the bad cable pairs and repair the cable by moving data to the good cable pairs.
D. The Virtual Circuit Test command config ethernet 6/2 vct test can detect opens, shorts, bad terminations.
Question 3
The attempt to manage an Ethernet Routing Switch (ERS) 8000 using a Virtual Route Redundancy Protocol (VRRP) address was not successful. What is causing this problem?
A. The virtual router identifier is 0.
B. The data center interface is set as a critical IP interface.
C. The virtual router identifier is configured for the VRRP IP address owner.
D. A real IP address is required for management access not a VRRP address.
Question 4
A call centre is using the stacks of Ethernet Routing Switches (ERS) 5520-48T- PWR to supply power over Ethernet (PoE) to their IP telephones. Each switch is attached to 48 telephones. The call centre begins operation at 9:00 am each day and they
verify that the
switch can supply
enough power to support each telephone drawing their maximum power for all switches simultaneously. They are using the IP Phone port 10/100 switch. Which statement it is true if all telephones are drawing 13.2 watts simultaneously?
A. Each switch of supplying full port to all ports with only the AC input
B. Each switch requires an RPSU 15 in addition to AC to supply full power to all ports.
C. RPSU 15 can support four ERS 5520 switches that supply full power to all ports.
D. Each switch can supply full power to all ports while the AC is unavailable if attached to
Question 5
The
IEEE 802.1aq virtualized service standard supports two
modes
of operation for the implementation of shortest path Bridging. Which mode is supported in the Avaya VENA Enterprise Fabric solution?
A. Shortest Path Bridging Mac-In-Mac (SPBM)
B. Shortest Path Bridging SID (SPBS)
C. Provider link state bridging (PLSB)
