An analysis of the full cosmic microwave background (CMB) sky by the Wilkinson Microwave Anisotropy Probe (WMAP) has revealed that the two lowest cosmologically interesting multipoles, the quadrupole (l=2) and the octopole (l=3) moments of the temperature variations, are unexpectedly aligned with each other. In this paper, we demonstrate that, whereas this alignment constitutes a statistically significant anomaly in the standard model, it is statistically insignificant within the context of the R_h=ct Universe. The key physical ingredient responsible for this difference is the existence in the latter of a maximum fluctuation size at the time of recombination, which is absent in LCDM because of inflation.
